1, as with a hand pushing to normal, is part of a display board field scanning weld or field scanning Trimming Potentiometer due to poor contact, there is a disconnection signal line.2, the signal line can be removed on the old display, look at the board on the socket is the same, and then look at the end of the assembly line, plug part of the line color is the same as the original location, if the same can be directly replaced.3, if not line problems, see if the motherboard has open welding place, if don"t understand, don"t do it yourself, the monitor after power failure still exist high pressure, careless will be electric shock.sThere is little refresh rate of 120HZ CRT, and even lower resolution can not be achieved. But to the inappropriate refresh rate will damage the hardware, really I used to have CRT is what I adjust the refresh rate gaohuai.sDo you think the LED is dazzling when you look at most of the white pages? That"s right, because now LED are low cost high light LED, even at 0 brightness are very bright, looking at the will of course be dazzling, CRT has now gone, you can then use CRT, can suggest to the landlord to see second-hand second-hand market CCFL LCD backlight. Because of the CCFL backlight display also discontinued, remember one of the most important parameter is the choice of a backlight, CCFL backlight, CCFL backlight display spectrum partial Green Blue Multi LED wave looks a lot of soft, though not necessarily more comfortable than CRT but certainly much better than LED, really do not want to use the old I recommend you are a brand: Yi Zhuo, Zhuo Yi display the quality control of excellence, sophisticated technology of other manufacturers is difficult to match. Even if the same is zhuoneng LED light-emitting display art LED control was lower than that of the other display, and the shading Eizo display in a low brightness is very good, if you want to buy a new LED display recommended Eizo EV series, if there is a CCFL backlight display better channel to buy Yi Zhuo this, basically can satisfy your requirements of the eye, the most economical way is to buy a second-hand CCFL backlit displays1.LCD is suitable for families, schools, offices, is the mainstream display, can meet the demand, but it shows the effect of miss CRT.2.CRT as imaging home tube television, the theory can be displayed on the infinite color and picture saturation, dynamic picture response time of 1 milliseconds, but the body is thick.3.LCD liquid crystal display, lightweight and slim, but only shows hundreds of thousands of limited colors, but high resolution, good static images, but the dynamic response time is about 5 ms. 4., professional video and animation are now using CRT display. ]sRadiation: the radiation of CRT is large, and LCD is not zero radiation. It"s only much smaller than conventional CRT radiation.Color: CRT absolute advantage. LCD"s best panel at the moment is 10bit, 16.7M. And CRT in this regard is an absolute advantage, in theory, unlimited color. So the current field of professional graphics still uses CRT.Refresh: since CRT is a tube light, so no matter how high refresh, has just reached 75HZ eye blinking, will obviously feel, while LCD is due to pixel directly display color, there is no refresh problem.Resolution: CRT, as long as the bandwidth is large, it can theoretically achieve unlimited resolution. Since LCD is made up of pixels, it can only have an optimum resolution, otherwise the difference display is very poor. For example, the 15 inch LCD panel is 1024*768 pixels, so the best resolution is 1024*768. 17 inches, 19 deposits are 1280*1024 pixels.Speed: CRT basically no delay. Similarly, due to the imaging principle of LCD CRT, CRT is luminous, the speed of light is needless to say. And LCD has response time problem, even if the fastest 2MS at the moment, there will be a shadow.Life: CRT life generally will be in 5~10 years, but there is an aging process in the middle, will slowly occur, focus is not allowed, brightness reduction and other issues. CRT life in 3~5 years, as long as the use of caution, do not force to stimulate panels, generally no problem.sLet"s buy a Philip!!!!!!!Just when everyone had Longguan buys, but high radiation, high power consumption, the problems brought about to make just in time. Longguan MAG also fire a!!! But, if the color saturation, reducing accuracy, life quality, frequency, customer service.... or to see Philip Samsung!!! After the fall, May 2005 Samsung has already poor customer service. As everyone knows...!!! so... We are practicing the display. Besides Philip other brands are very common!!!!!sCRT is the abbreviation of "cathode ray tube", which is a display which uses electronic emission to hit phosphor to display images. Oscilloscope tube similar to television screen and oscilloscope.s

CRTs are analog devices controlled by the varying voltages in the signal. There are also two controls for each of the three "beams" coming off the electron gun: bias and gain. When the three bias controls and gain controls are lumped together, you have contrast and brightness. All of these together control the floor and ceiling of the amplification (black and white luminance) as well as how quickly the luminance of the display increases from black to white. These are the controls most users know.

LCDs are digital devices and are a completely different animal. When run digitally, there is no bias or gain and in some instances...no contrast adjustment. The only variation is the intensity of the backlight. This is how LCDs connected to a computer through a DVI or ADC cable will operate. Unfortunately, digital interfaces for displays did not exist when LCDs were first introduced, so manufacturers tried to graft on analog controls since an analog signal was being used. This has caused mixed results. In most cases, setting brightness and/or contrast too high on an LCD with an analog connection will introduce clipping of the lighter tones.

Our goal is to achieve the highest contrast ratio and luminance without introducing clipping. We are measuring the luminance of a white patch and a very light gray patch and checking to see if there is an appropriate difference between them. We have found that some displays (usually laptops) will not produce a large enough luminance difference between the two patches regardless of the contrast setting. You can do this test visually. The alternating patches will be displayed continuously. If you can see them change with contrast all the way up, you can proceed. If not, turn the contrast down until you can see the difference and then proceed.

LCDs respond rather slowly to contrast and brightness adjustments and may take some time to stabilize. Since they change over time, this can cause the luminance of two sequential measurements to be greater or smaller, thus causing the indicator to move. That"s why we recommend waiting for the indicator to stabilize. When the indicator stabilizes, the display probably has as well.

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/.

A CRT (cathode-ray tube) monitor is an analog display device that creates a visible image on the screen by directing three electron beams over millions of phosphor dots to make them light up. In a color monitor, the screen is composed of numerous stripes of alternating red, green, and blue phosphor dots, which get activated by the electrons and combine to make countless different hues.

The electron beam repetitively scans the entire front of the tube to “paint” and refresh the image nearly 100 times every second. Computer monitors and televisions that use CRT technology have large, heavy physical casings. The long length between the front screen and the back of the case is necessary to accommodate the length of the vacuum tube.

Cathode-ray tubes were commonly used in televisions and computer monitors throughout the mid-to-late 1900s. Throughout that time, manufacturers continually improved performance and resolution. Most computer monitors in the 1970s only displayed green text on a black screen. By 1990, IBM’s Extended Graphics Array (XGA) display boasted 16.8 million colors in 800 x 600 pixel resolution.

Some gamers believe the faster refresh rate and minimal motion blur of CRT monitors creates a better gaming experience, especially for older titles with lower-resolution graphics.

In the early 2000s, advances in technology made flat-panel displays more accessible. These newer display types (LCD, plasma, and OLED) don’t require a large casing and are more energy efficient. Manufacturing costs are lower than for CRT monitors, and flat-panel displays can be made in larger sizes than CRTs. These factors make flat-panel displays far more popular among consumers.

Depending on how old you are, you may remember your parents chiding you for sitting too close to the TV and claiming that it would damage your eyes. However, these fears seem to be largely unsubstantiated. There are some legitimate health and safety concerns with CRT monitors, but none of them link sitting too close to the screen with negative effects on eyesight.

There is a significant amount of stored electrical charge in a CRT, even one that’s powered off. Breaking a CRT monitor or attempting to dismantle it without proper tools and training can lead to a severe electrical shock.

If you have a CRT monitor you no longer want, it’s not safe to toss it in your trash can. You should contact your local authorities for information on safe disposal methods and/or recycling options.

While flat-panel LCD and OLED monitors and televisions are more common nowadays than CRTs, the older technology is still superior in some ways. A CRT monitor can display/refresh an image faster than an LCD screen. This means the monitor can respond faster to input and avoid motion-blur issues that are common in LCD screens. The color range and contrast is often better on a CRT, and this type of monitor supports deeper black tones. For some computer gamers, these advantages are enough to warrant scouring the internet for old CRT monitors.

If you want to check out the benefits of a CRT monitor for yourself, prepare for a bit of work. Because CRTs aren’t manufactured anymore, you won’t be able to grab one at your local big box store. You’ll probably be able to find a decent selection on eBay or through Craigslist or your local thrift store. CRT monitors can be pricey, especially if you have to pay for shipping, and it’s important to make sure you choose a model that’s compatible with your computer or gaming console.

When LCDs took over the market in the early 2000s, most companies drastically reduced their CRT manufacturing to account for the decreased demand. Sony stopped making CRT monitors in 2005, and 2008 was the last year Samsung introduced new CRT models. Despite pleas from a small number of passionate gamers who prefer CRT screens over LCDs, the lack of adequate market demand will likely prevent any major company from restarting production any time soon.

CRT, which stands for Cathode-Ray Tube, is an antiquated type of display technology that was commonly used in televisions and computer monitors in the 1900s. While CRT displays are no longer manufactured, they maintain some advantages over modern LCD, OLED, and plasma displays, and are sometimes prized by gamers.

With the advent of LCD screens in the early 2000s, CRT displays became less popular. LCDs are more compact, more energy-efficient, and cost less to make. They can also be made with larger screen sizes than CRT monitors. They’re vastly lighter; a 21-inch CRT display can weigh between 50 and 60 pounds, and some weigh nearly 100 pounds. One of the rarest and most sought-after CRT monitors, the Sony GDM-FW900, had a screen size of 24” and a widescreen aspect ratio of 16:9 and weighed about that much.

However, modern displays are not totally superior to CRT screens. CRT displays can refresh the display at a faster rate than LCDs, making motion on the screen appear smoother with less motion blur. CRTs also have higher contrast ratios and tend to have superior color ranges.

While CRT displays are no longer made, they are sometimes sought after by gamers for their superior refresh rates and contrast ratios. They are also able to avoid the problem of input lag, which is when commands on a controller take longer to register.

LCD gaming displays are catching up to CRTs, however, and can be obtained with comparable refresh rates to CRTs. Still, motion blur remains an issue even on the highest-end gaming monitors.

Finally, retro games were simply designed with CRT in mind, meaning older video games don’t have an authentic look on modern display technologies. Retro gamers commonly want their experience to be as close to the original as possible, and using a modern LCD monitor just doesn’t have the same effect.

CRTs do not support modern display interfaces such as HDMI or DisplayPort. Instead, they typically use VGA. Unlike CRT, the VGA interface is still manufactured today. However, modern graphics cards and motherboards typically do not have a VGA port. Thankfully, you can remedy this with an adapter. Not all adapters are equal, though, so make sure the adapter you use supports the resolution and refresh rate you plan to use.

To understand dot pitch, you need to understand a little about how a CRT screen creates an image. CRT monitors shoot electrons toward the phosphors at the front of the machine, which is then filtered by either a shadow mask or an aperture grill. The sharpness of the image is defined by how large the gaps in the shadow mask or aperture grill are. The shorter the distance, the sharper the image. This is referred to as dot pitch, and it is measured in millimeters.

If you want the sharpest possible display on a CRT monitor, you’ll want one with a dot pitch below .28 millimeters. It’s very rare for a dot pitch to fall below .21 millimeters, but the lower, the better.

If you want to display an image with a high resolution (say, above 1600 x 1200) on a CRT monitor, the dot pitch becomes especially relevant. If the dot pitch is too large, an image will look blurry at higher resolutions. However, if you only intend to use lower resolutions, dot pitch has little impact on the sharpness of the screen. Regardless of the resolution you use, it is best not to go above .28 millimeters to ensure adequate clarity.

Each of these technologies works differently to filter electrons at the front of the screen. A shadow mask uses a metal sheet with evenly spaced holes, and an aperture grill uses a wire array. Both will create a comprehensive color image to generate the final product you see on the screen.

Generally, an aperture grill will display a better image than a shadow mask, creating a brighter and more colorful image because it handles light better. However, this is not always the case, and some CRTs with shadow masks have superior image quality than those with aperture grills.
