comparison of crt and lcd monitors for sale

CRT stands for Cathode Ray Tube and LCD stands for Liquid Crystal Display area unit the kinds of display devices wherever CRT is employed as standard display devices whereas LCD is more modern technology. These area unit primarily differentiated supported the fabric they’re made from and dealing mechanism, however, each area unit alleged to perform identical perform of providing a visible variety of electronic media. Here, the crucial operational distinction is that the CRT integrates the 2 processes lightweight generation and lightweight modulation and it’s additionally managed by one set of elements. Conversely, the LCD isolates the 2 processes kind one another that’s lightweight generation and modulation.

Since the production of cathode ray tubes has essentially halted due to the cost and environmental concerns, CRT-based monitors are considered an outdated technology. All laptops and most desktop computer systems sold today come with LCD monitors. However, there are a few reasons why you might still prefer CRT over LCD displays.

While CRT monitors provide better color clarity and depth, the fact that manufacturers rarely make them anymore makes CRTs an unwise choice. LCD monitors are the current standard with several options. LCD monitors are smaller in size and easier to handle. Plus, you can buy LCD monitors in a variety of sizes, so customizing your desktop without all the clutter is easy.

The primary advantage that CRT monitors hold over LCDs is color rendering. The contrast ratios and depths of colors displayed on CRT monitors are better than what an LCD can render. For this reason, some graphic designers use expensive and large CRT monitors for their work. On the downside, the color quality degrades over time as the phosphors in the tube break down.

Another advantage that CRT monitors hold over LCD screens is the ability to easily scale to various resolutions. By adjusting the electron beam in the tube, the screen can be adjusted downward to lower resolutions while keeping the picture clarity intact. This capability is known as multisync.

The biggest disadvantage of CRT monitors is the size and weight of the tubes. An equivalently sized LCD monitor can be 80% smaller in total mass. The larger the screen, the bigger the size difference. CRT monitors also consume more energy and generate more heat than LCD monitors.

For the most vibrant and rich colors, CRTs are hard to beat if you have the desk space and don"t mind the excessive weight. However, with CRTs becoming a thing of the past, you may have to revisit the LCD monitor.

The biggest advantage of LCD monitors is the size and weight. LCD screens also tend to produce less eye fatigue. The constant light barrage and scan lines of a CRT tube can cause strain on heavy computer users. The lower intensity of the LCD monitors coupled with the constant screen display of pixels being on or off is easier on the eyes. That said, some people have issues with the fluorescent backlights used in some LCD displays.

The most notable disadvantage to LCD screens is the fixed resolution. An LCD screen can only display the number of pixels in its matrix. Therefore, it can display a lower resolution in one of two ways: using only a fraction of the total pixels on the display, or through extrapolation. Extrapolation blends multiple pixels together to simulate a single smaller pixel, which often leads to a blurry or fuzzy picture.

For those who are on a computer for hours, an LCD can be an enemy. With the tendency to cause eye fatigue, computer users must be aware of how long they stare at an LCD monitor. While LCD technology is continually improving, using techniques to limit the amount of time you look at a screen alleviates some of that fatigue.

Significant improvements have been made to LCD monitors over the years. Still, CRT monitors provide greater color clarity, faster response times, and wider flexibility for video playback in various resolutions. Nonetheless, LCDs will remain the standard since these monitors are easier to manufacture and transport. Most users find LCD displays to be perfectly suitable, so CRT monitors are only necessary for those interested in digital art and graphic design.

There are two primary types of computer monitors in use today: LCD monitors and CRT monitors. Nearly every modern desktop computer is attached to an LCD monitor. This page compares the pros and cons of both the CRT type displays and LCD or flat-panel type displays. You"ll quickly discover that the LCD or flat-panel displays pretty much sell themselves and why they are the superior display used today.

LCD monitors are much thinner than CRT monitors, being only a few inches in thickness (some can be nearly 1" thick). They can fit into smaller, tighter spaces, whereas a CRT monitor can"t in most cases.

Although a CRT can have display issues, there is no such thing as a dead pixel on a CRT monitor. Many issues can also be fixed by degaussing the monitor.

LCD monitors have a slightly bigger viewable area than a CRT monitor. A 19" LCD monitor has a diagonal screen size of 19" and a 19" CRT monitor has a diagonal screens size of about 18".

A German scientist called Karl Ferdinand Braun invented the earliest version of the CRT in 1897. However, his invention was not isolated, as it was among countless other inventions that took place between the mid-1800s and the late 1900s.

CRT technology isn’t just for displays; it can also be utilized for storage. These storage tubes can hold onto a picture for as long as the tube is receiving electricity.

Like the CRT, the invention of the modern LCD was not a one-man show. It began in 1888 when the Austrian botanist and chemist Friedrich Richard Kornelius Reinitzer discovered liquid crystals.

CRT stands for cathode-ray tube, a TV or PC monitor that produces images using an electron gun. These were the first displays available, but they are now outdated and replaced by smaller, more compact, and energy-efficient LCD display monitors.

In contrast, a Liquid crystal display, or an LCD monitor, uses liquid crystals to produce sharp, flicker-free images. These are now the standard monitors that are giving the traditional CRTs a run for their money.

Although the production of CRT monitors has slowed down, due to environmental concerns and the physical preferences of consumers, they still have several advantages over the new-age LCD monitors. Below, we shed some light on the differences between CRT and LCD displays.

FlickeringFlickering is recognizable by the naked eye because of the monitor’s low refresh rateFlickering is almost negligible thanks to its high refresh rate

CRTs boast a great scaling advantage because they don’t have a fixed resolution, like LCDs. This means that CRTs are capable of handling multiple combinations of resolutions and refresh rates between the display and the computer.

In turn, the monitor is able to bypass any limitations brought about by the incompatibility between a CRT display and a computer. What’s more, CRT monitors can adjust the electron beam to reduce resolution without affecting the picture quality.

On the other hand, LCD monitors have a fixed resolution, meaning they have to make some adjustments to any images sent to them that are not in their native resolution. The adjustments include centering the image on the screen and scaling the image down to the native resolution.

CRT monitors project images by picking up incoming signals and splitting them into audio and video components. More specifically, the video signals are taken through the electron gun and into a single cathode ray tube, through a mesh, to illuminate the phosphorus inside the screen and light the final image.

The images created on the phosphor-coated screen consist of alternating red, blue, and green (RGB) lights, creating countless different hues. The electron gun emits an electron beam that scans the front of the tube repetitively to create and refresh the image at least 100 times every second.

LCD screens, on the other hand, are made of two pieces of polarized glass that house a thin layer of liquid crystals. They work on the principle of blocking light. As a result, when light from a backlight shines through the liquid crystals, the light bends to respond to the electric current.

The liquid crystal molecules are then aligned to determine which color filter to illuminate, thus creating the colors and images you see on the screen. Interestingly, you can find color filters within every pixel, which is made up of three subpixels—red, blue, and green—that work together to produce millions of different colors.

Thanks to the versatility of pixels, LCD screens offer crisper images than CRT monitors. The clarity of the images is a result of the LCD screen’s ability to produce green, blue, and red lights simultaneously, whereas CRTs need to blur the pixels and produce either of the lights exclusively.

The diversity of the pixels also ensures LCD screens produce at least twice as much brightness as CRTs. The light on these screens also remains uninterrupted by sunlight or strong artificial lighting, which reduces general blurriness and eyestrain.

Over time, however, dead pixels negatively affect the LCD screen’s visual displays. Burnout causes these dead pixels, which affect the visual clarity of your screen by producing black or other colored dots in the display.

CRT monitors also have better motion resolution compared to LCDs. The latter reduces resolution significantly when content is in motion due to the slow pixel response time, making the images look blurry or streaky.

With CRTs, you don’t experience any display lag because the images are illuminated on the screen at the speed of light, thus preventing any delays. However, lag is a common problem, especially with older LCD displays.

CRTs are prone to flickeringduring alternating periods of brightness and darkness. LCDs don’t flicker as much thanks to the liquid pixels that retain their state when the screen refreshes.

CRTs have a thick and clunky design that’s quite unappealing. The monitor has a casing or cabinet made of either plastic or metal that houses the cathode ray tube. Then there’s the neck or glass funnel, coated with a conductive coating made using lead oxide.

Leaded glass is then poured on top to form the screen, which has a curvature. In addition, the screen contributes to about 65% of the total weight of a CRT.

LCDs feature low-profile designs that make them the best choice for multiple portable display devices, like smartphones and tablets. LCD displays have a lightweight construction, are portable, and can be made into much larger sizes than the largest CRTs, which couldn’t be made into anything bigger than 40–45 inches.

The invention of the cathode ray tube began with the discovery of cathode beams by Julius Plucker and Johann Heinrich Wilhelm Geissler in 1854. Interestingly, in 1855, Heinrich constructed glass tubes and a hand-crack mercury pump that contained a superior vacuum tube, the “Geissler tube.”

Later, in 1859, Plucker inserted metal plates into the Geissler tube and noticed shadows being cast on the glowing walls of the tube. He also noticed that the rays bent under the influence of a magnet.

Sir William Crookes confirmed the existence of cathode rays in 1878 by displaying them in the “Crookes tube” and showing that the rays could be deflected by magnetic fields.

Later, in 1897, Karl Ferdinand Braun, a German physicist, invented a cathode ray tube with a fluorescent screen and named it the “Braun Tube.” By developing the cathode ray tube oscilloscope, he was the first person to endorse the use of CRT as a display device.

Later, in 1907, Boris Rosing, a Russian scientist, and Vladimir Zworykin used the cathode ray tube in the receiver of a television screen to transmit geometric patterns onto the screen.

LCD displays are a much more recent discovery compared to CRTs. Interestingly, the French professor of mineralogy, Charles-Victor Mauguin, performed the first experiments with liquid crystals between plates in 1911.

George H. Heilmeier, an American engineer, made significant enough contributions towards the LCD invention to be inducted into the Hall of Fame of National Inventors. And, in 1968, he presented the liquid crystal display to the professional world, working at an optimal temperature of 80 degrees Celsius.

Many other inventors worked towards the creation of LCDs. As a result, in the 1970s, new inventions focused on ensuring that LCD displays worked at an optimal temperature. And, in the 1980s, they perfected the crystal mixtures enough to stimulate demand and a promotion boom. The first LCDs were produced in 1971 and 1972 by ILIXCO (now LXD Incorporated).

Although they may come in at a higher price point, LCD displays are more convenient in the long run. They last almost twice as long as CRTs are energy efficient, and their compact and thin size make them ideal for modern-day use.

LCDs are also more affordable compared to other display monitors available today. So, you can go for a CRT monitor for its ease of use, faster response rates, reduced flickering, and high pixel resolution. However, we don’t see why you should look back since there are so many new options that will outperform both CRTs and LCDs.

If you are shopping for a display, you may look to compare LCD vs CRT computer monitors. Some of the best computer monitors come in a wide variety of styles and design types. Keep reading to learn the difference between these two types of monitors.

CRT displays, however, are known for superior color rendering performance and for offering high refresh rates. We have a whole page dedicated to explaining what a CRT monitor is if you’re curious.

CRT monitors are bad for the environment, as they draw a whole lot of power during use. To help reduce humanity’s carbon footprint through tech products, there are opportunities for computer monitor recycling.

There are multiple distinctions to be made between LCD and CRT monitors, as well as LCD vs LED monitors, but that’s for another post. A liquid crystal display (LCD) has liquid crystals squeezed between two sheets of glass along with an electron gun that shoots an electron beam, while a CRT (cathode ray tube) monitor features a number of cathode-ray tubes. This overall difference in design leads to widely different use case scenarios, such as when you are comparing LCD vs LED monitors for gaming.

Despite being an older technology, CRT monitors are quite capable when it comes to rendering accurate colors. As a matter of fact, many creative professionals opt for expensive newly made CRT screens over LCD technology, LED screens, or even OLED displays for just this reason. Another advantage to the bright and vivid colors found with CRT displays is that they slightly reduce eye fatigue, which can be a handy bit of information if you are comparing LCD vs LED monitors for eye strain. The downside here is that CRT monitors are fragile, so this color accuracy will break down over time as the phosphor tubes degrade.

Another surprising feature of CRT monitors is their ultra-fast refresh rates. Due to the nature of the design, they offer higher refresh rates than LCD screens, as the light has a shorter route to travel.

There is no way around it. Cathode tubes are extremely large and extremely heavy, making CRT monitors an absolute beast to haul around and to place in your workspace. LCD screens, on the other hand, are light and portable, easily fitting just about anywhere.

In most cases, LCD monitors will offer a much larger field of view for viewing image and video than CRT displays, due to the nature of the design of the flat screen. Something like an LCD screen would come in handy as a gaming monitor. The larger the field of view with a CRT, the heavier and bulkier it will be.

CRT monitors are made from multiple materials that are relatively tough to source and they draw a whole lot of power during use. In other words, they are not too great for the environment.

Text and images (scans of census records) are crisper and sharper and the LCD monitor is easier on your eyes. Monitor"s size: Traditional monitors are similar to a TV because both of them have the CRT (Cathode Ray Tube). That is the reason for its bigger size. It therefore occupies more space at the desk. It is also heavy.

However, LCD monitors have thin flat screen. Therefore occupies very less space and is lighter than the CRT monitor. LCD monitors can be fixed even on wall. Display Size: Even though the display size of a CRT monitor is calculated diagonally, the actual display size is smaller. For instance a 17" CRT monitor will actually have a display size of only 16" However, the display size of 17" LCD monitor will have 17" display size. Resolution: CRT monitors can show different resolutions. The resolution can be changed as required. LCD Monitors will have Native Resolution and therefore has a fixed resolution. The best resolution will be the native resolution for that LCD monitor. Viewing Direction: A CRT screen can be viewed from all directions. And from different distance. But LCD monitors cannot be viewed from all directions. LCD monitors can only be viewed straight. Therefore its viewing direction is limited. If viewed from other directions the colors will change and sometimes the vision will be unclear if not viewed straight. But in recent years the new LCD monitors have improved on this defect. Radiation Emission: The radiation emission in CRT monitors are higher. This will not be visible normally but it will affect eyesight and may cause head ache. Long term use of these monitors may even affect the eyes adversely. LCD monitors do not have this type of Radiation emission. Therefore LCD monitors are good for the eyes. Price: CRT monitors are priced very cheap. However they consume more power. LCD monitors are priced higher, but they consume less electricity. Though the electricity consumption is not very significant for personal use, it is very cost efficient in big organizations with many computers.

Text and images (scans of census records) are crisper and sharper and the LCD monitor is easier on your eyes. Dot pitch: This is the space between dots and is measured in fractions of a millimeter, e.g., .25mm. The smaller the number the better because the dots are tighter. Many manufacturers don%u2019t even list the dot pitch anymore and you probably won%u2019t be able to tell the difference between a .22 and .27 pitch anyway. So, if you like the monitor then don%u2019t worry about the dot pitch. Passive-matrix vs. active-matrix: Do not buy a passive-matrix monitor. I seriously doubt you%u2019ll even see one for sale, but%u2026just in case. Having said that, there are some new passive-matrix technologies that are worth buying. If the monitor isn"t TFT (a type of active-matrix), look for CSTN or DSTN (the latest passive technologies). Brightness: How bright is the picture, expressed as cd/m (I have no idea what the units mean). Look for a brightness level of 200 cd/m or greater. Again, if the monitor specs don%u2019t list this value (not all do) be sure you can get your money back. If the lighting in your office (kitchen table) is subdued the brightness factor won%u2019t be as important as if you have a lot of sunlight streaming in. Don%u2019t pay extra for extra brightness unless you%u2019re worried about bright sunlight. Overall, the contrast ratio will have a bigger impact on picture quality. Monitor"s size: Traditional monitors are similar to a TV because both of them have the CRT (Cathode Ray Tube). That is the reason for its bigger size. It therefore occupies more space at the desk. It is also heavy. However, LCD monitors have thin flat screen. Therefore occupies very less space and is lighter than the CRT monitor. LCD monitors can be fixed even on wall. Display Size: Even though the display size of a CRT monitor is calculated diagonally, the actual display size is smaller. For instance a 17" CRT monitor will actually have a display size of only 16" However, the display size of 17" LCD monitor will have 17" display size. Resolution: CRT monitors can show different resolutions. The resolution can be changed as required. LCD Monitors will have Native Resolution and therefore has a fixed resolution. The best resolution will be the native resolution for that LCD monitor.

Speaking of easy on your eyes, there isn"t any glare, and the flat screen means no distortion. By the way, even those expensive old-fashioned flat screen CRT monitors have some distortion. Monitor"s size: Traditional monitors are similar to a TV because both of them have the CRT (Cathode Ray Tube). That is the reason for its bigger size. It therefore occupies more space at the desk.

If you are looking for a new display, you should consider the differences between CRT and LCD monitors. Choose the type of monitor that best serves your specific needs, the typical applications you use, and your budget.

Require less power - Power consumption varies greatly with different technologies. CRT displays are somewhat power-hungry, at about 100 watts for a typical 19-inch display. The average is about 45 watts for a 19-inch LCD display. LCDs also produce less heat.

Smaller and weigh less - An LCD monitor is significantly thinner and lighter than a CRT monitor, typically weighing less than half as much. In addition, you can mount an LCD on an arm or a wall, which also takes up less desktop space.

More adjustable - LCD displays are much more adjustable than CRT displays. With LCDs, you can adjust the tilt, height, swivel, and orientation from horizontal to vertical mode. As noted previously, you can also mount them on the wall or on an arm.

Less eye strain - Because LCD displays turn each pixel off individually, they do not produce a flicker like CRT displays do. In addition, LCD displays do a better job of displaying text compared with CRT displays.

Better color representation - CRT displays have historically represented colors and different gradations of color more accurately than LCD displays. However, LCD displays are gaining ground in this area, especially with higher-end models that include color-calibration technology.

More responsive - Historically, CRT monitors have had fewer problems with ghosting and blurring because they redrew the screen image faster than LCD monitors. Again, LCD manufacturers are improving on this with displays that have faster response times than they did in the past.

Multiple resolutions - If you need to change your display"s resolution for different applications, you are better off with a CRT monitor because LCD monitors don"t handle multiple resolutions as well.

So now that you know about LCD and CRT monitors, let"s talk about how you can use two monitors at once. They say, "Two heads are better than one." Maybe the same is true of monitors!

The obsolescence of CRT monitors requires replacing stimulators used for eliciting VEPs with new monitors. Currently, LCD monitors are the only suitable alternative, however other technologies, like OLED, may become a viable option [23]. So far, the ISCEV extended protocol for VEP methods of estimation of visual acuity recommends ensuring luminance artifacts caused by non-CRT stimulators [9], which can be achieved by reducing the stimulus contrast [23]. However, this may not be possible without falling below the minimum contrast values recommended for VEP [1, 23]. Since LCD stimulators have been shown to result in mostly a delay in the VEP responses [2,3,4, 23] but seem not to affect the size of the amplitudes [2], we expected no difference between the estimated visual acuity by using LCD or CRT monitors used as a stimulator for the sweep VEP.

The results of the first experiment show statistically significant effects of the monitor type on the time-to-peak after stimulus onset and the peak-to-trough amplitude (Table 1). The mean delay of the time-to-peak after stimulus onset between recordings obtained using the LCD and the CRT monitor was about 60 ms, which is quite high and possibly caused by the relatively old LCD monitor used. Accordingly, statistically significant effects on the time-to-peak after stimulus onset and the peak-to-trough amplitude were found for the monitor/contrast combination in the results of the second experiment (Table 4). Surprisingly, the mean delay of the time-to-peak after stimulus onset of the CRT monitors with high contrast was with up to 151 ms, longer (Table 5) than that of the LCD monitors (with low and high contrast), although one would expect modern monitors to have shorter or even no delays [24, 25]. Additionally, a statistically significant interaction between the spatial frequency and the monitor type was revealed in both experiments, causing an increased time delay for the intermediate spatial frequencies (1.4–10.3 cpd) with LCD stimulation (Fig. 2, top left) in the first experiment and an almost linear increase with the spatial frequencies in the second experiment (Fig. 2, bottom left). This may be explained by the semi-manual cursor placement, which is necessary because the amplitudes are less pronounced at frequencies below and above this frequency band. Another cause might be an input lag resulting from the time required by the monitor to prepare the image data to be displayed. This could be caused by, e.g., internal scaling for non-native resolutions, which may even be present when using the monitor’s native resolution. In the worst case, this leads to nonlinearities of the response timing of the LCD monitor when presenting patterns of low or high frequency [26, 27]. In doubt, the precise duration of the input lag should be measured using a photodiode attached to the display [28] and in case of being constant, the delay could then be subtracted from the respective time-to-peak values. Finally, the higher latencies may also be caused by the different software used for generating the stimuli: whereas in the first experiment, a custom-developed Java-based software was used, in the second experiment, the Python-based PsychoPy was employed. Nevertheless, these differences seem not to affect the estimated visual acuity. The mean peak-to-trough amplitude using the LCD monitor in the first experiment is reduced by about 0.9 µV with a confidence interval from − 1.6 to − 0.2 µV compared to the CRT stimulator, but increased by about 2.6 µV (confidence interval from 1.2 to 4.0 µV) when comparing the new LCD monitor with the CRT monitor (both with high contrast) in the second experiment (Table 5). However, these differences were, despite being statistically significant, within the expected standard deviation from about 0.5 to 7 µV of the P100 amplitude found in the literature [29,30,31] and therefore probably of no clinical relevance (Fig. 2, right). Interestingly, the results of Nagy et al. [2] suggest a similar reduction in the peak-to-trough amplitude when using an LC display for stimulation. In the first experiment, no statistically significant interaction between monitor type and spatial frequency on peak-to-trough amplitude was found but a tendency to smaller amplitudes at intermediate frequencies (Table 1), whereas in the second experiment, the effect of the interaction of stimulator and spatial frequency was statistically significant (Table 4). It has to be taken into account that the residuals of the models were heteroscedastic and therefore the statistical significance of the effects may be overestimated [32].

In the first experiment, the difference between the subjective visual acuity and that estimated by the second-order polynomial method, or by the modified Ricker function, was not statistically significant from a hypothetical assumed value of 0 logMAR (Table 2). Neither were the variances between CRT and LCD statistically different. Accordingly, the linear mixed-effects models revealed no statistically significant effects of neither the monitor type, the recording cycle, nor their interaction on the difference between subjective and estimated visual acuity for both estimation methods (Table 3).

In contrast in the second experiment, the differences between subjective visual acuity determined using FrACT and the visual acuities estimated using the modified Ricker function along with the conversion formula used in the first experiment were significantly different from the hypothesized difference of 0 logMAR for both, the new gaming LCD monitor and the old LCD monitor, at high and low contrast, but not for the CRT monitor. After using an individually adjusted conversion formula for each monitor/contrast combination, no statistically significant difference from the hypothesized difference of 0 logMAR was found (Table 7). However, one should keep in mind that using the results to calculate the conversion formula used to predict the results is circular reasoning. Nevertheless, it indicates, that using individual established conversion formulas calculated from a sufficiently large number of normative data will minimize the error between true visual acuity and estimated visual acuity.

Table 6 lists the signal-to-noise ratio calculated from the fitted Ricker model for the different combinations of monitors and contrasts. The highest SNR was found for the CRT monitor using high contrast. The LCDs showed lower SNR values. The on average higher amplitudes obtained using LCD monitors (Table 5) indicate that more noise is present when stimulating using LCDs. However, this effect could be caused by the different software used for the stimulus presentation and the lower number of sweeps recorded for averaging compared to the recordings using the CRT monitor. Nevertheless, none of the differences between the SNR values obtained from the different monitor types was statistically significant (Table 6), which corresponds to the findings of Fox et al. [28].

We want to point out the limitations of the current study: We included only healthy participants, so the possible effects of LCD stimulators on patients with reduced visual acuity remain unclear and should be further investigated, especially since we found a statistically significant, albeit not clinically relevant, effect of the monitor/contrast combination on peak-to-trough amplitude and time-to-peak after stimulus onset in the second experiment (Tables 4, 5). Further limitations are that the participants were not stratified by age and that the subjective visual acuity in the first experiment was determined using an eye chart projector, in contrast to the second experiment, where FrACT was used, limiting the accuracy of the estimated value. Finally, this study compared only three specific monitors; therefore, the results are not universally valid.

In conclusion, based on the results of this study, LCD monitors may substitute CRT monitors for presenting the stimuli for the sweep VEP to objectively estimate visual acuity. Newer LCD screens, especially with low response times in the range of 1–2 ms, therefore, allow for a reduction in luminance artifacts at required contrast levels [23], albeit the luminance artifact may not have a large effect on the recorded signals [28]. New technologies like OLED displays [23] may even be better suited, since one the one hand, the onset will be the same for the whole pattern, and on the other hand, LCDs and OLEDs provide a constant luminance level during stimulation, whereas CRTs need a constants pulses to keep the phosphor lit up, causing fast local luminance flashes all the time [28]. Therefore, in contrast to CRTs, LCD and OLED stimulators, e.g., may allow for recording true offset responses [33]. However, caution should be taken when leveraging modern displays for stimulation, since their in-built electronics perform all kinds of sophisticated image-enhancing procedures including color-correction, brightness boosting, contrast enhancement by real-time adjustments of the colors or the backlight, or eyestrain-reducing blue light filtering, with the aim to improve the users’ experience, or to increase the monitors lifetime. This applies in particular to consumer electronics like TVs. Gaming monitors, in addition, use special acceleration drivers, which shut down the backlight, insert black frames (Black Frame Insertion, BFI), or employ variable refresh rates (e.g., Nvidia G-SYNC or AMD FreeSync) to clean the retained image from the eye. Therefore, one should disable any image processing or enhancing functionality in the monitor settings, before using the monitor as stimulator for electrophysiological experiments. Finally, it is advisable to perform a calibration with healthy volunteers using best-corrected and artificially reduced visual acuity and to collect normative data for the employed setup, as always recommended by ISCEV [34], in order to establish an individual conversion formula between the sweep VEP outcome and the estimated visual acuity.

CRT monitors have surged back to relevance on a wave of nostalgia, driven by the exploding popularity of retro gaming. Unfortunately, most of the reviews, specification sheets, and comparison data that once existed has vanished from the Internet, making it difficult to know what you should look for while scanning eBay and Craigslist ads.

If you’re looking for a newer display filled with the latest and greatest goodies, our guides to the best PC monitors, best 4K monitors, and best gaming monitors can help you find the perfect fit for your needs. But this particular guide will get you up to date on aging, but still hotly desired CRT monitors.

CRT monitors fell from fashion with the same breathtaking speed as portable CD players and vinyl records. Three out of four monitors sold in 2001 were a CRT. But in 2006, Sony drew curtains on the era when it ceased production of new CRT TVs and monitors.

Still, CRTs have their perks. Most have a better contrast ratio and higher refresh rates than modern LCD monitors, so content looks richer and deeper. There’s a sub-culture of first-person shooter fans who swear FPS games always look best on a high-end CRT monitor.

A CRT is also a window into an entire era of media. Films, movies, and games produced from the dawn of television to around 2004 were created with a CRT in mind. You can enjoy older media on a modern LCD or OLED, but it will never look as originally intended. A CRT computer monitor is the most versatile, practical choice for tapping into nostalgia.

One quick note: This guide is for CRT computer monitors, not professional video monitors. PVMs are high-end CRT televisions. They’re amazing for retro console gaming but aren’t designed for use with a computer.

Sony’s Trinitron dominates the conversation just as it does in the world of retro CRT televisions and PVMs. Trinitron computer monitors are excellent, easy to find, and come from Sony, a brand people still recognize today. Other outstanding brands include Mitsubishi, Hitachi, LaCie, NEC, Iiyama, and Eizo.

Dell, Gateway, HP, and Compaq monitors are less loved, but this can be an opportunity. Large PC manufacturers didn’t make monitors in-house but rebranded monitors from others, and some use the same CRT tubes found in Trinitrons and other brands. Deciphering what’s in a rebrand can be difficult, though, so you may need to take a leap of faith.

I don’t recommend fretting brands and models if this is your first CRT. Trying to find a specific monitor is frustrating and, depending on your dream monitor, can take years (or cost thousands of dollars). Still, keep brand in mind when negotiating price. A Gateway monitor with mystery specifications might look great, but it’s not worth top dollar.

CRTs were improved and refined over the years. The oldest CRT monitors commonly sold are pushing forty years of age. They have a low maximum resolution, a low refresh rate, and small physical display size.

Newer CRT monitors, such as those produced in the mid-90s and the 2000s, will look sharper, handle reflections better, and have less noticeable lines or gaps in the image they display. You’re also find better on-screen menus with extensive image quality options.

Luckily, CRT monitors often have a label indicating the year or even month of production. This is printed on the rear of the display or might be found on a sticker in this same location. Newer is better, and a CRT built this millennia are best.

Most CRT computer monitors have a display size between 13 and 21 inches. If you follow my advice and stick with newer monitors, though, you’ll be comparing monitors between 15 and 21 inches.

I don’t recommend going below 17 inches unless you’re trying to replicate the experience of a late-80s or early-90s computer or have very limited space. Smaller CRT monitors feel tiny by modern standards. They also tend to support lower resolutions that are only ideal for enjoying older content.

There’s such a thing as too large, too, so be cautious about massive CRTs. A 21-inch CRT monitor can weigh 50 or 60 pounds. You’re unlikely to run into a CRT computer monitor larger than 21 inches, and if you do, it can weigh nearly 100 pounds. The Sony GDM-FW900, a truly epic 24-inch 16:9 CRT, is the most well-known of these rare beasts.

19 inches is the sweet spot. This size of CRT monitor remains manageable. It’s about as tall as a 24-inch LCD (though narrower, of course) and isn’t too hard to find. With that said, 17-inch monitors are more common and less expensive, so don’t hesitate to leap on a 17-incher if you find one.

Resolution works differently on a CRT computer monitor than on a modern LCD. CRT monitors are an analog technology and don’t have a native resolution. CRT monitors were sometimes marketed with a “recommended” resolution that served as a guideline, but CRTs computer monitors support a range of input resolutions and refresh rates.

Take the Hitachi SuperScan 751 as an example. This 19-inch CRT computer monitor lists a maximum resolution of 1600 x 1200 at 85Hz but supports 1024 x 768 at 130Hz and 640 x 480 at 160Hz.

In general, the best resolution is the highest you can find. A monitor with a high maximum resolution will also support lower resolutions, and often a higher refresh rate. A resolution of 2048 x 1536 is the highest you’re likely to see. 1600 x 1200 is more common.

The importance of resolution depends on your use. I use my CRT monitor to run Windows 95/98 in a virtual machine, play late-90s PC games, and emulate console games. All of these were designed with lower resolutions in mind, so the content I’m viewing is usually at a resolution of 1024 x 768 or lower.

If you want to use a CRT monitor to play Doom: Eternal at insane refresh rates with near-perfect response times, however, you’ll prefer the highest resolution you can find. Resolution is not the final word on CRT monitor sharpness but in general a higher resolution will appear sharper.

Dot pitch is the distance between dots in a shadow mask or the distance between wires in an aperture grill. More on that in a moment. Remember that a CRT shoots electrons at the front of the display. The shadow mask or aperture grill filters the electrons so they hit phosphors at the front of the display and create a usable color image. The gaps in the shadow mask or aperture grill influences how sharp the image appears.

Dot pitch is measured in millimeters. I recommend monitors with a horizontal dot pitch around .28 millimeters or lower. A dot pitch between .24 millimeters and .21 millimeters is excellent. Lower is better, but you likely won’t find a monitor with a dot pitch below .21 millimeters in your search.

Make dot pitch a priority if you care about sharpness at resolutions beyond 1600 x 1200. A monitor with a lackluster dot pitch might support a high resolution but appear blurrier at a high resolution than a low resolution. This occurs when a CRT monitor’s dot pitch isn’t up to the task.

Dot pitch is less important if you only care to use a CRT at lower resolutions. Late-model CRT monitors will be enjoyable at 800 x 600 or 1024 x 768 no matter the dot pitch listed on their spec sheet.

A shadow mask or aperture grill is a filter a CRT computer monitor uses to make sure electrons end up where they should be. A shadow mask does the job with a metal mask of evenly spaced holes. An aperture grill uses an array of wires instead. Sony was the first to introduce aperture grill technology under the Trinitron brand name, but Sony wasn’t the only company that sold CRT monitors with an aperture grill.

In general, a monitor with an aperture grill will be superior to one with a shadow mask. The aperture grill blocks less light than a shadow mask, which translates to a brighter and more colorful picture. The aperture grill is also better suited for a flat CRT display, though flat shadow mask CRTs were produced.

That’s not to say shadow masks were trash. Hitachi and NEC put a ton of effort into shadow mask technology to rival Sony’s Trinitron and had success. A late-model Hitachi ErgoFlat or NEC ChromaClear is a great monitor. If you’re comparing two random, mid-range monitors, though, the aperture grill will probably be brighter and more attractive.

As mentioned, CRT monitors support a range of resolutions and refresh rates. The higher the resolution, the lower the refresh rate. Most late-model CRT monitors had a refresh rate of at least 75Hz at maximum resolution. Lower resolutions come with higher supported refresh rates with the best models topping out at 200Hz.

Refresh rate and resolution are linked. CRT monitors with the best refresh rates also support the highest resolutions. If you want the best refresh rate, then, you’ll need to keep an eye out for a top-tier CRT monitor, and you should expect to use it at a resolution lower than the maximum it supports.

Obsessing over a CRT’s refresh rate is often not worth the trouble. CRT monitors feel smooth not just because of refresh but also thanks to fundamental differences in how an image is produced. Nearly all late-model CRT monitors support a refresh rate of at least 75Hz at their maximum supported resolution and look exceptionally smooth.

Most CRT televisions and monitors have curved (also known as convex) glass. This was necessary to fix some problems of CRT technology. CRT makers found ways to overcome these issues by the mid-1990s and flat CRT displays hit the market. Shoppers loved them and flat-screen models dominated the final years of CRT production.

The big difference is the most obvious: Curved CRT monitors are curved, and flat CRT monitors aren’t. Your choice should come down to the “feel” you’re going for. A curved CRT will feel more accurate to a mid-90s PC or earlier, while flat screens were more common after the turn of the millennium. Those looking to use a CRT with modern software and games will prefer a flat screen as well.

The vast majority of CRT computer monitors you’ll encounter have a VGA video input. This is likely the only input on the monitor. It’s an analog technology that most modern computers do not support, so you’ll need an active DisplayPort or HDMI to VGA adapter. I use a StarTech adapter from Amazon.

Be careful about the adapter you purchase. Many, including the one I purchased, have a maximum resolution and refresh rate below the best CRT monitors available. It works for me because I’m mostly driving lower resolutions and my CRT monitor is a mid-range model. But I would need to upgrade if I bought a better CRT.

While VGA dominates by far, it’s not the only input you might find. A handful of late-model CRTs support a version of DVI-A or DIV-I, which can provide an analog signal. CRT monitors from the 1980s might use a different video input. Commodore 1701 and 1702 monitors, for example, can use a composite input (just as you’d find on a CRT television).

What dot pitch is best? .28 millimeters or lower is fine for general use. Look for .24mm or lower if you want to display a resolution of 1600 x 1200 or higher.

The fastest way to buy a CRT monitor is eBay or Etsy. Hundreds of CRT computer monitors are available, including many that fit the recommendations of this guide. You’ll have to spend several hundred dollars, however, and you can’t see the monitor before buying. Shipping is a gamble, too. Many fine CRTs have met their demise in the hands of Fedex.

Local listings like Craigslist, OfferUp, and Facebook Marketplace can help you find a more affordable monitor, but stock can be limited depending on your location. Rural readers may have to search for months or drive long distances. Try to test the CRT before you buy, especially if it’s not sold at a low price. Ask the seller to have it connected to a PC when you arrive.

Don’t neglect searching offline. I snagged my current CRT computer monitor for free from someone a few blocks away who decided to put old electronics on the curb. Yard sales and estate sales are great, too. They can be a grind if you don’t enjoy the search, but you’ll spend a lot less than you would online.

Put out the word, as well. Post on social media about your search and ask relatives if they have a hidden gem. CRT monitors aren’t easy to move or dispose of, so they’re often stuffed in a closet, attic, or basement. Many people will let you have a monitor to get it out of their hair.

Good luck on your search. Just remember: The best CRT monitor is the one you own. Don’t be too harsh on the CRTs you come across. Your first task is finding one that meets your needs and reliably works. After that, you can get picky. Once again, if you’re looking for a newer display filled with the latest and greatest goodies, our guides to the best PC monitors, best 4K monitors, and best gaming monitors can help you find the perfect fit for your needs.

Resolution on a CRT is flexible and a newer model will provide you with viewing resolutions of up to 1600 by 1200 and higher, whereas on an LCD the resolution is fixed within each monitor (called a native resolution). The resolution on an LCD can be changed, but if you’re running it at a resolution other than its native resolution you will notice a drop in performance or quality.

Both types of monitors (newer models) provide bright and vibrant color display. However, LCDs cannot display the maximum color range that a CRT can. In terms of image sharpness, when an LCD is running at its native resolution the picture quality is perfectly sharp. On a CRT the sharpness of the picture can be blemished by soft edges or a flawed focus.

A CRT monitor can be viewed from almost any angle, but with an LCD this is often a problem. When you use an LCD, your view changes as you move different angles and distances away from the monitor. At some odd angles, you may notice the picture fade, and possibly look as if it will disappear from view.

Some users of a CRT may notice a bit of an annoying flicker, which is an inherent trait based on a CRTs physical components. Today’s graphics cards, however, can provide a high refresh rate signal to the CRT to get rid of this otherwise annoying problem. LCDs are flicker-free and as such the refresh rate isn’t an important issue with LCDs.

Dot pitch refers to the space between the pixels that make up the images on your screen, and is measured in millimeters. The less space between pixels, the better the image quality. On either type of monitor, smaller dot pitch is better and you’re going to want to look at something in the 0.26 mm dot pitch or smaller range.

Most people today tend to look at a 17-inch CRT or bigger monitor. When you purchase a 17-inch CRT monitor, you usually get 16.1 inches or a bit more of actual viewing area, depending on the brand and manufacturer of a specific CRT. The difference between the “monitor size” and the “view area” is due to the large bulky frame of a CRT. If you purchase a 17″ LCD monitor, you actually get a full 17″ viewable area, or very close to a 17″.

There is no denying that an LCD wins in terms of its physical size and the space it needs. CRT monitors are big, bulky and heavy. They are not a good choice if you’re working with limited desk space, or need to move the monitor around (for some odd reason) between computers. An LCD on the other hand is small, compact and lightweight. LCDs are thin, take up far less space and are easy to move around. An average 17-inch CRT monitor could be upwards of 40 pounds, while a 17&-inch LCD would weigh in at around 15 pounds.

As an individual one-time purchase an LCD monitor is going to be more expensive. Throughout a lifetime, however, LCDs are cheaper as they are known to have a longer lifespan and also a lower power consumption. The cost of both technologies have come down over the past few years, and LCDs are reaching a point where smaller monitors are within many consumers’ price range. You will pay more for a 17″ LCD compared to a 17″ CRT, but since the CRT’s actual viewing size is smaller, it does bring the question of price back into proportion. Today, fewer CRT monitors are manufactured as the price on LCDs lowers and they become mainstream.

First, we will provide a brief technical overview of functional principles as they relate to visual stimulus presentation. Detailed descriptions and parameter measurements are already available from the existing literature; however, our intention here is to equip readers with limited technical expertise with the necessary knowledge to set up computer experiments with LCD monitors. Thus, we keep our explanations relatively short and simplified.

LCD monitors work differently: Each pixel consists of liquid crystal threads that can be twisted or arranged in parallel by an electrical current applied to them. This leads to a polarization effect that either allows or prevents light passing through. A white light source located behind this crystal array uniformly and constantly illuminates the array. To display a black pixel, the crystal threads are twisted by 90° such that no light will pass through. A white pixel is achieved by aligning the crystals such that maximum light is allowed to pass through, until a different, non-white color needs to be displayed (see the lower panel of Fig. 1 for an LCD pixel’s brightness over time). This is a static process, not a pulsed one as in CRTs.

In theory, the difference in presentation methods, namely a strobing versus a static image, should be of no consequence if the light energy that falls onto the retina remains the same over the time period of one single frame. As the Talbot-Plateau law states2 is equally well detectable as a light flash presented for 60 ms at 40 cd/m2. This suggests that temporal integration can be easily described by energy summation”. Thus, in principle, LCD and CRT monitors should be able to yield comparable results.

However, due to the differences in technology, the visual signals produced by the two display types have different shapes (i.e., a different light energy-over-time-curve; see Fig. 1). Moreover, default luminance as well as visual-signal response times (in addition to other parameters, see below) differ between most CRT and LCD monitors

Table 1 reports the parameters we considered in setting up the CRT and LCD monitors. Certainly, most of them are commonly considered when setting up a computer experiment; nevertheless we deemed it important to mention them here explicitly, as their neglect might have unintended consequences. We used a 17” Fujitsu Siemens Scenicview P796-2 CRT color monitor previously used in several published studies including studies with masked presentation conditions

We tested various monitor user settings, refresh rates, resolutions and luminance settings (see materials available at https://osf.io/g842s/) with regard to the emitted light energy–over-time-curve and therefore response characteristics (i.e., onset and offset of full screen and centrally presented stimuli). Measurements were conducted with a photodiode setup, using both an oscilloscope (model “Agilent MSOX 3012 A”) and a self-developed microcontroller setup as measurement devices. Stimuli were black and white squares.

Our measurements revealed several interesting characteristics: First, luminance of the LCD monitor at default setting (i.e., maximum brightness) exceeded the CRT luminance at a ratio of 3.25:1. However, comparable average luminance can be (and was) achieved by downregulating the LCD monitor (the older CRT technology emits less energy even at maximum settings, see Table 2), without participants perceiving it as unnaturally dark. If one plans to upgrade from CRT to LCD monitors in an experimental laboratory, we therefore recommend measuring the CRT monitors’ brightness levels and matching them in the new LCD monitors’ user setup, if comparability with the old setup is needed. This will minimize hardware-dependent variability, thus contributing to better replicability. Please note that a brightness adaption is not a necessary precondition when employing LCD monitors; researchers should simply be aware that the brightness level can have an influence onto the resulting effects, especially in time-critical experiments with short and/or masked presentation. Thus, we recommend the adaptation for time-critical experiments in which researchers orient on existing empirical evidence gathered with CRT monitors. Furthermore, gray-to-gray response times varied slightly depending on the employed brightness levels2), so we suggest that researchers can rely on this more efficient method as an approximation.

For the empirical comparison of human performance with CRT and LCD monitors, we relied on these results and set the monitor settings accordingly (see Method section below).

Participants were administered a masked number priming task and a subsequent forced-choice prime discrimination task using both a CRT and an LCD monitor. In this well-established paradigm

Of central interest was the question whether both monitors would yield comparable masked priming effects. Monitors were set according to the parameters described in the previous section (see also Method section below). In order to obtain conclusive evidence, we decided for sequential hypothesis testing using Bayes factorshttps://osf.io/g842s/.

As of July 2021, CRT monitors are no longer in production. Even if you managed to get a used CRT monitor, there is a issue of connecting it to your system as newer PCs/notebooks come equipped only with HDMI and/or DisplayPort display ports. However, this can be worked around using HDMI to VGA adapters.

The viewable area is about 0.9 - 1.1 inch smaller than the size specified on paper. This is due to the frame around the glass screen. So a 15" CRT would have only about 14" of viewable area.

17 inch LCD has 17 inch viewable. 24 inch LCD has about 23.8" viewable depending on model. Slightly less viewable as sizes go bigger, but not as severe as CRT.

Many manufacturers tout true flatness for their CRT monitors, but the sad truth is that most are fake. In reality it is only the outer glass that is flat, and not the actual screen. The true 100% perfect flat monitors are the aperture grille tubes made by Mitsubishi and Sony. Even then, these tubes have a disadvantage - a faint thin line or two (depending on size) running through the screen to stabilize the grill. Some people find this distracting, especially if you work on a white background (eg. documents) most of the time.

CRTs emit electromagnetic radiation. Much of it is filtered by the lead heavy glass front and the rest that reaches your eyes are mostly harmless. Even then, radiation still passes through the screen and some people regard them as hazardous.

CRTs weigh heavier, especially in the front (the display area) 17 inch CRT weighs around 16kg. 19 inch CRT weighs around 20kg.

Higher power usage, more than 400% compared to an LED backlight LCD of equivalent size. 17 inch CRT requires around 90 watts 19 inch CRT requires around 110 watts

LCDs are free from the burn-in issue that plagues CRTs and Plasma displays. However, they do occasionally have Image Persistence problems which can be fixed by switching off the LCD for an extended period of time.

LCDs do not "paint" their image. They provide a flicker free image every time. However, games and fast moving videos benefit from a higher refresh rate monitor by appearing smoother

LCD panels are prone to dead or stuck pixels (or dots) on the screen due to their manufacturing process. However, stiff competition has made many manufacturers adopt zero dead pixel / stuck pixel warranties for their products.

Must be used at its native resolution (maximum resolution) for best quality. Using the display at a lower resolution will result interpolation (scaling of the image), causing image quality loss. For this reason, gamers should avoid buying a monitor too high a resolution (e.g. 4K) as you will need more processing power (and more fan noise) to run the game in native resolution. As of 2021, we recommend 1920 x 1080 monitors when paired with recent GPUs/processors.

As CRT monitors are no longer manufactured, LCD monitors are the only way to go. Our recommendation is to go for a LED backlight LCD monitor that has a native resolution of 1920 x 1080.

Currently I am using a curved 31.5 inch 1920 x 1080 G-Sync 144hz monitor - the Acer Predator Z321 Qbmiphzx. It was bought from Amazon UK but it is no longer available as of July 2021. My reason was that it was the biggest G-Sync monitor I could get for 1080p resolution as I did not want Windows to scale font sizes (but I still had to anyway). Before this I was using a 26" Sony LCD TV as a monitor for its 1360 x 768 resolution.

Always preferred tube TV"s, I always had one plus the way they work interests me. I sill got my 36 inch Sony hd tube good tv I won"t make the mistake of buying a cheap liquid crap display again I wasted $150 for 1 year of tv then it burned out meanwhile my old tube doesnt even show signs of wear. So don"t waste time buying liquid crap. Lol

I don"t really like LCD"s, I prefer Old CRT TV"s because it works better with my VCR, and old video gaming systems, with LCD it has the VHS tapes have black bars at the sides and same with the video games. Ssame with my grandson (who is currently 12), so we switched back to our 25 inch CRT zenith Televison and everything went smooth, my grandson enjoys it too.

I have a CRT TV and used to have a LCD HDTV and I think I liked both but I had huge problems with an LCD TV because the screen broke easily and I called up to repair it but my warranty has expired and unable to repair my TV. So I bought another TV and its a Samsuck LED LCD TV and same sh*t happens again. So I give up and used my Old CRT TV left in the storage and I have no problems with this thing. So in conclusion I think CRT TVs are bit better then LCD but I liked LCD because it has HD 1080p and I can save up some space on my table to put stuff on it.

I have both CRT and LCD, but prefer CRT because ic an play at lower resolution (but with AA) this requires less powerfull videocard. Also i like to play old games that have low resolution. LCD displays look crappy whenusing low resolution

Seriously looks like a Windows bashing Linux, or visa-versa. Most of the facts where so outdated, at the time this comparison was written, that it isn"t even funny. LCD only had 8bit color, in 2008? More like 16. But don"t take my word for it, Google is your friend!

You should really make sure the comparisons at the bottom always list CRT on the same side, currently you"re switching between left and right, which makes for a very confusing read. Fix that and it"ll
