lcd displays common for sale

Unfortunately, most of that stuff requires either a certified repair or a complete replacement to fix. Unless you’re especially handy with electronics and you just happen to have access to cheap replacement parts, it’s usually better to either return a monitor to the manufacturer (if it’s under warranty) or simply buy a new one. Even so, here are the most common ailments for modern LCD monitors, and what can be done to fix them…or not.

An incorrect refresh rate setting can also cause flickering. The refresh rate is the number of times the computer sends an image to the monitor per second, expressed in hertz. Most LCD monitors use either 59 or 60 hertz, though 75Hz, 120Hz, and 144Hz are also found on premium monitors. Go into your operating system’s display settings (right-click desktop and head to Display settings > Display adapter properties > Monitor in Windows 10) to make sure the right hertz setting is applied—you may need to update your video drivers as well.

Black or single-colored lines on LCD screens are caused by a lot of different issues, but if the standard fixes outlined in the flickering section above don’t fix them (check your video and power cables for problems, install new drivers), it’s probably a physical defect in the screen itself. Try your monitor on another computer or laptop to see if the problem persists; if it does, you’re probably looking at a replacement, since the error is almost certainly in the LCD panel (the most expensive component of the monitor).

A “dead” pixel is a single dot on your LCD screen that doesn’t illuminate, showing up as one or more black squares. “Stuck” pixels are similar, but instead of showing black they’re stuck on a single color that doesn’t match the computer screen’s image, typically either red, green, or blue.

If your monitor has a visible crack, a large discolored area, or a black/multicolored spot that doesn’t align with the pixel grid, it’s been subjected to physical trauma and the LCD panel is damaged. There’s nothing you can do here: even if your monitor is within its warranty period, it almost certainly won’t cover physical damage. You could try to replace the LCD panel itself, but since the replacement part will be almost as expensive as a new monitor anyway, you might as well start shopping.

The most common problem that can cause a buzz or whine noise in a monitor is an issue with the backlight, usually with the compact florescent tubes used for lighting in older models. (This design has been largely superseded by LED backlighting, but there are still plenty of CFL-equipped monitors in use.) Buzzing can occur due to problems in power regulation to one or more bulbs. Try adjusting the brightness of your screen up or down to see if the noise dissipates; of course, this can be a less than optimal solution if you need your screen brightness at a specific setting.

Most of the above problems can happen to the LCD screens used in laptop PCs and tablets, too…but because of the compact build, they’re much harder to repair. That being said, the extra expense of a laptop versus a monitor might make it a much better candidate for a repair rather than a replacement. At the very least (assuming you’re out of the warranty period), it’s probably worth a diagnosis and quote at a repair shop, if you’re not comfortable replacing the screen assembly yourself.

It is such a waste to only use the LCD for desktop computers. Connecting it up with a laptop PC has many merits for the user and can also bring out the latent power of the laptop.

A laptop can be put to more effective use if it is connected to an external LCD. The photograph shows an EIZO 23-inch wide-screen LCD connected by HDMI to a Sony VAIO C laptop (VPCCW28FJ/R).

This time we would like to suggest a style that can be used in both the home and the office, where a laptop and stand-alone LCD remain connected. A laptop already has an LCD, but using it with an additional stand-alone LCD offers various merits. Not only does it make the laptop environment more pleasant and convenient, it also expands the potential of the computer itself, for example by making it possible to use it for new purposes.

Even if the LCD is already connected to a desktop computer and being used for something other than the laptop, most monitors nowadays have two or more video inputs and they tend not to use this capability to the full. It is such a waste to let the laptop"s external display output function and the monitor"s video input function remain dormant, so we would like them to be put to effective use. Of course, we would also recommend the introduction of a new LCD to connect to your laptop.

The biggest merit of connecting a laptop with a stand-alone LCD is that it gives you a large screen and high resolution dual display environment. Standard laptop models usually come with a built-in 13-inch to 15-inch wide-screen LCD with a 1280 × 800 dot or 1366 × 768 dot resolution.

Another plus is that you can create the luxury of a "watching while" environment where you run the web browser, for instance, on the laptop"s built-in LCD and watch the video content on the large screen of the external monitor. This can be really useful for hobbies too. For example, while playing a game on the large external LCD screen you can check out strategies on websites, post information on a BBS or communicate with other users.

You can smoothly use multiple applications at the same time in the large workspace provided by a dual display. The photograph shows an EIZO 24.1-inch wide-screen LCD, the FlexScan SX2462W connected to a VAIO C. By supplementing the laptop"s built-in 1366 × 768 dot 14-inch wide-screen LCD with a 1920 × 1200 dot 24.1-inch wide-screen, it is possible to show more data at a time, a huge boost to work efficiency.

With two screens it"s easy to have full-screen display of the video content on one screen while you operate the computer on the other. The photograph shows an EIZO 23-inch wide-screen LCD monitor connected to a VAIO C. The VAIO C has HDMI output and the LCD monitor has HDMI input so visuals and sound can be transmitted by a single HDMI cable. The LCD monitor has full HD screen resolution (1920 × 1080 dot), making it the perfect match for HD video content.

At the office, it is very helpful for presentations to use "clone view" for the laptop"s built-in LCD and the external LCD screen. Clone view means showing exactly the same content on two display screens. It is normally set by a graphics driver function.

When holding small meetings it is certainly very convenient to be able to offer simple explanations of the presentation materials displayed on the external LCD, rather than having to ready a projector. Being able to explain about what is displayed on the screen means fewer documents to distribute, helping your office to "go paperless", which can only be a good thing.

Even if the upper limit is 1680 × 1050 dots, the LCD can still display the data if its own resolution is 1680 × 1050 dots or higher. In such cases, it is better to use a monitor that offers dot-by-dot display, which displays the input resolution as it is, or enlarged display, which maintains the screen"s aspect ratio as it is. You do not need to worry because EIZO wide-screen LCDs can handle such display methods (although in some cases they do not function properly depending on the laptop computer or input resolution).

This is an example of a low-resolution display on the 1920 × 1200 dot display SX2462W. Since dot-by-dot display outputs the physical "1 dot" of the LCD and the input resolution "1 dot" without enlargement or reduction, it is shown small in the center of the screen (photo on the left). The display is a little blurred if it is enlarged while maintaining the aspect ratio, but this method is suitable for displaying images as they are shown large with low resolution to make the most of the screen size (photo on the right). Many monitors that cannot handle such display methods enlarge the display to full screen regardless of the input resolution. In such cases you have to be careful as the aspect ratio of the image is altered (for example, people appear to be thinner or fatter).

It is easy to set up a dual display in Windows 7. A menu is displayed when you right-click on the desktop. From "Screen resolution" it is possible to detect and align the external LCD, and set details such as resolution, display method and which will be the main display screen.

The "Screen resolution" menu. If the external LCD is not automatically recognized, click on "Detect". After the monitor has been recognized, you can select the display mode from the "Multiple displays" drop-down menu. Select "Extend display screen" to make the laptop screen and the external LCD into a single display screen (dual display).

Select "Duplicate display screen" from the "Multiple displays" drop-down menu to display the same content on the laptop screen and the external LCD screen (clone view). With this drop-down menu you can also set it to display video on one of the LCDs.

It is also worth noting that Windows 7 has added functions so that dual display can be used more effectively. An active window can be moved to the screen of another LCD by simultaneously pushing "Windows" + "Shift" + "→" (or "←"). It is also possible to maximize the window by pressing "Windows" + "↑", minimize it by pressing "Windows" + "↓", and shift it to the left or right of each screen by pressing "Windows" + "→" (or "←"). Making good use of these shortcuts should enable the efficient placing of windows in the two screens.

We would recommend a wide-screen model with a screen resolution of 1920 × 1080 dots (Full HD) or 1920 × 1200 dots (WUXGA) as the LCD to connect to a laptop, so that you can make full use of the advantages of dual display. EIZO has an extensive line up of wide-screen LCDs which can offer many benefits, in addition to the merits of a large screen and high resolution, when used with a laptop for dual display.

With a 24.1 inch wide-screen like the SX2462W, an A3 sheet (two A4 sheets side by side) can be viewed in actual size, particularly effective for paper-based creative work ITmedia LCD Course II, Lesson 3: Which is better, 16:10 or 16:9 ? – "Screen size / resolution / aspect ratio"

We must not forget that EIZO"s wide-screen LCDs have non-glare screens (processed to reduce ambient light reflection). Nowadays the trend is for laptops to have an LCD with glare (glossy) surface treatment. While these can display images in bright color, reflected ambient light can sometimes be distracting.

A laptop screen is not so large and adjusting its angle can avoid the reflection of lights and so on, however it is not so easy with the large screen of an external LCD. When it comes to the large screen of an LCD in habitual use, a non-glare type that is not reflective is probably easier to see, as well as being kinder on the eyes. A large screen, high resolution and non-glare ensure that you can comfortably continue viewing over a prolonged period of time.

The surface treatment of an LCD makes a difference to the background reflection. Glare panels do not diffuse background light, making it easier to achieve high color purity, but easily reflect the user or lights (photo on the left). If the lights are similarly trained on a non-glare panel they do not have much effect, only appearing as a fuzzy brightness (photo on the right).

Another distinctive feature of EIZO wide-screen LCDs is a commitment to energy saving. They incorporate various power saving features that support "EcoView". A pivotal feature is the "EcoView Sense" adopted in the FlexScan EV series, such as the EV2333W.

This is the motion sensor on the front of the LCD. It constantly monitors the user"s movements to automatically take finely-tuned power saving measures. To be more precise, if the user"s presence is not detected for a specified period of time, for example if he leaves his seat, the monitor automatically switches to power save mode, and then automatically switches back when the user"s presence is detected again.

Other features include "Auto EcoView", which automatically optimizes the brightness of the LCD based on ambient lighting, and "EcoView Index", which displays a meter on the screen showing how much power is being saved. All these features can be expected to have a strong energy saving effect and to boost the user"s awareness of power saving, making them particularly useful in the office.

A standard laptop computer switches to sleep mode if the built-in LCD is closed while it is running but, if this function is turned off, a laptop can be treated as a "small desktop computer."

It can be set to use only the connected external LCD and not to react when the laptop"s built-in LCD is closed. The transformation into a small desktop PC is complete if you add a keyboard and mouse connected to the laptop via USB ports, for example. The OS is still running even though the laptop"s built-in LCD is closed, so you can carry out normal operations using the external keyboard and mouse, and also use the laptop"s built-in optical drives.

The idea is to use a large screen, high resolution external LCD at home or in the office, and to use the laptop"s built-in LCD as usual for mobile purposes. This helps to boost the longevity of the laptop"s built-in LCD and many people do use their laptop in this way. If you feel reluctant to use a dual display environment, where the screen is split in two, why not give this a try?

Select "Only show the desktop on 2" from the "Multiple displays" list in the "Screen resolution" menu. The laptop"s built-in LCD will be switched off and the external LCD will become the main display.

By making this simple setting your laptop can be used as a space saving desktop computer. Another plus is that the laptop"s built-in LCD will last longer.

Recently some high-end laptop computers, such as the Sony VAIO F, are insisting on good display quality for their LCDs. However, a typical laptop"s built-in LCD does not have as good image quality as a stand-alone LCD. This is only natural since the costs allowed for display quality are completely different for an LCD incorporated into the PC as one of its parts and a specialized LCD.

However, by using an EIZO wide-screen LCD a laptop user can still fully enjoy such benefits of a stand-alone high-quality LCD as excellent color reproduction, a wide viewing angle, more even display and a wealth of items that can be adjusted to improve image quality. This is a crucial point for people who use their computer for photographs and videos in particular.

EIZO"s wide-screen LCDs emphasize color reproduction, and the coloration in sRGB mode has a high degree of accuracy. The standard color gamut used in PC environments and Internet content is sRGB, so you need have no worries about viewing or editing videos and photographs. They can also display images on web pages, such as products in online shops or goods for sale in online auctions, in colors that are very close to the real thing. (This is also influenced by how the seller took the photographs and processed the images, so we cannot say that the colors will always be accurate.)

In this case, if the image is edited on the external LCD with its high color reproducibility and the many tool palettes in the application are grouped in the laptop"s built-in LCD, there is less need to display or hide the tool palettes or to switch back and forth, and the image data to be edited can be displayed in a large form, making for more efficient work.

In this case, if the image is edited on the external LCD with its high color reproducibility and the many tool palettes in the application are grouped in the laptop"s built-in LCD, there is less need to display or hide the tool palettes or to switch back and forth, and the image data to be edited can be displayed in a large form, making for more efficient work.

When doing things like photo retouching, using software where there is a lot of switching between tool palettes it is very handy to display the image data to be edited on the external LCD with its high color reproducibility, and to gather the palette tools to be used on the laptop"s built-in LCD.

Going back to the subject of laptop computers, it is not going too far to say that applications and functions are being spoiled in laptops whose built-in LCD"s image quality is not too good. Connecting a laptop to a monitor with high image quality dispels any concerns about work that deals with colors and also helps to bring out the laptop"s potential.

Combining an EIZO wide-screen LCD with a laptop computer makes viewing videos and images even more fun. Just being able to see them on a large screen is a pleasure, but what makes it even better is that our LCDs are equipped with Fine Contrast, the optimum image quality mode for video and visuals. You can also use the Custom mode to create the image quality you prefer.

We expect that you now understand how displaying screens from a laptop computer on a stand-alone LCD can create a very pleasant environment. It feels as if your everyday laptop has been transformed into a completely different desktop machine. Even if you only use laptop computers, it is definitely worthwhile to add a stand-alone LCD.

When choosing the type of LCD the most important consideration is to choose one with overall high quality. When it comes to that, we can recommend EIZO wide-screen LCDs to a broad range of laptop users. In addition to their high image quality, EIZO wide-screen LCD are built with careful attention to detail, including non-glare screens, versatile stand features, dot-by-dot capability, abundant image quality modes, and our proprietary eco-functions. We want you to make full use of your beloved laptop computer along with an EIZO wide-screen LCD.

This time we have spoken about how an external LCD can be connected to a laptop computer, but if your main machine is a desktop computer then you probably already have a LCD.

In which case, why not consider adding a full HD (1920 × 1080 dot) or WUXGA (1920 × 1200 dot) wide-screen LCD and creating a more advanced dual display environment to further enhance your computer"s usability.

The dual display environment of a desktop PC has a wider range of options than a laptop computer, which is already installed with an LCD. Depending on the combination of products used you can seek for a larger screen, higher resolution and better image quality.

You can get a super high resolution of 3840 × 1200 dots in total by putting two 24.1-inch 1920 × 1200 dot wide-screen LCDs side by side. The advantage in this is that a larger screen and higher resolution are achieved at a lower cost than buying a single 30-inch high resolution model

There are tons of screens available in the market today. However, LED screens and LCD screens are by far the most popular. But what is the difference between LCD vs. LED screens?

The main difference between LCD and LED displays is that the LCD screens come with a layer of liquid crystals. The liquid crystal layer is put between two plates. Images are made when light passes through parts of the liquid crystal.

The liquid crystal part either block or enhance an area which helps to create the image. Most LCD panel types have LED lights that help bring out the image.

Older LCD screens and use Cold Cathode Fluorescent Lamps (CCFLs) to light the screen. The CCFLs use electron discharge and fluorescence to light the screen.

LEDs like the one from our "Dell Computer Ultrasharp 24.0-Inch Screen LED Monitor Review" are taking over the market while LCD screens with CCFLs are fading away. LCD screens are used in watches, some notebook computers, and calculators.

The Q in QLED stands for Quantum Dot (see Quantum Dot and IPS). The screens have an additional layer between the LCD screen and the backlight of the monitor. The layer allows light to pass through easily and produce better colors than an ordinary LED screen.

Slimmer design:LED screens to come in a slimmer design than their LCD counterparts. This gives them a sleek and elegant look, and it also takes less space.

Cheaper to run:If you are trying to cut down on energy cost, an LED screen will be a better option between the two as it is more energy-efficient. However, LED screens are more expensive than their LCD counterparts. As such, you can expect to pay more initially.

However, if you are working on a tight budget, you may consider an LCD screen. Besides the cost, LED performs better than the LCD screen in all the other aspects.

If you want to find out the type of screen you already have, you can check out the screen"s model number. The model number can tell you if the screen is an LED or LCD.

When it comes to picture quality, LED TVs look better than older LCD TVs. Manufacturers also make a big deal out of LED backlighting because sets that use the technology are usually more energy-efficient than CCFL LCD TVs. Therefore, the money you save on your power bill could eventually offset the extra cost of an LED TV.

You"ll be happy with the picture regardless of what kind of display you buy. Still, LED TV have a few practical advantages that make them a better purchase than the older LCD TVs.

Alternatively, you can go for LCD screens that offer arefresh rate of 120Hz or more. The LCD screens also offer a wider variety of viewing angles, which can offer better comfort.

When choosing between LED and LCD monitors, there are several factors to consider. Besides the backlighting technology, you should also consider the panel type - see also what types of monitors are there. Various panels have their benefits compared to others.

LED monitors tend to be more expensive than LCD screens, thanks to LED technology being newer and featuring pricier components. Additionally, there is a newer form of LED called the OLED, which stands for Organic Light-Emitting Diodes. These OLED displays are extremely expensive, especially at high resolutions. LED technology, on the other hand, is extremely cheap and readily available.

Are you lost on the best choice between LCD and LED monitors? If you spend a lot of time in front of your monitor, you should ensure you end up with the best quality screen. This will ensure that you get high-quality images and also minimize eye strain.

In the battle between LCD and LED displays, LED comes out as the better option. It offers more crisp and clear images, and it also comes with a sleek and elegant design. However, it can be a little expensive. If you are working on a budget, LCD monitors can make a perfect choice.

LED technology has improved drastically in recent years improving picture quality while driving costs down. LED is a bigger investment up front but generally has a lifespan of about 100,000 hours. LCD is cheaper and generally more familiar. A LCD screen typically has a lifespan of about 50,000 hours.

Sort of. Older technologies like LCD technology and Plasma displays are becoming obsolete due to the intrinsic properties of LEDs like brightness, efficiency, maintainability, and sustainability.

LCD screens emit blue light and thus negatively affects not only vision but also overall health. Continual extended screen time mainly can impact your eyes in two major ways. When we look at a screen, our blink rate drops significantly, thus causing digital eye strain.

Again, IPS is the clear winner here. The vertical viewing angles are very similar to the horizontal ones on both IPS and VA panels. Unfortunately, this is one area where TN panels are usually much, much worse. TN monitors degrade rapidly from below, and colors actually inverse - resulting in a negative image that can be distracting. For this reason, if you decide to buy a TN monitor, look for one with an excellent height adjustment, or consider buying a VESA mounting arm, as you should mount TN monitors at eye level. Even when mounted properly, larger TN displays can appear non-uniform at the edges.

Historically, TN panels used to have the worst colors, as many of them were cheaper models that only supported 6-bit colors or used techniques like dithering (FRC) to approximate 8-bit colors. Most displays today, including TN models, are at least 8 bit, and many of them are even able to approximate 10-bit colors through dithering. New technologies, like LG"s Nano IPS and Samsung"s Quantum Dot, add an extra layer to the LCD stack and have significantly improved the color gamut of modern IPS and VA displays, leaving TN a bit behind. Between them, NANO IPS is slightly better, as it tends to offer better coverage of the Adobe RGB color space. Although the difference is minor, IPS panels still have a slight edge over VA and TN displays.

Although not necessarily as noticeable to everyone as the differences in picture quality, there can also be a difference in motion handling between IPS, VA, and TN displays. TN panels historically offered the best gaming performance, as they had the highest refresh rates and extremely fast response times. Manufacturers have found ways to drastically improve the motion handling of VA and IPS panels, though, and the difference isn"t as pronounced.

LCD panel technology has changed drastically over the last few years, and the historical expectations for response time performance don"t necessarily hold anymore. For years, TN monitors had the fastest response times by far, but that"s started to change. New high refresh-rate IPS monitors can be just as fast.

VA panels are a bit of a strange situation. They typically have slightly slower response times overall compared to similar TN or IPS models. It"s especially noticeable in near-black scenes, where they tend to be significantly slower, resulting in dark trails behind fast-moving objects in dark scenes, commonly known as black smear. Some recent VA panels, such as the Samsung Odyssey G7 LC32G75T, get around it by overdriving the pixels. It results in much better dark scene performance but a more noticeable overshoot in brighter areas.

Within each of the three types of LCD we mentioned, other related panel types use the same basic idea but with slight differences. For example, two popular variants of IPS panels include ADS (technically known as ADSDS, or Advanced Super Dimension Switch) and PLS (Plane to Line Switching). It can be hard to tell these panels apart simply based on the subpixel structure, so we"ll usually group them all as IPS, and in the text, we"ll usually refer to them as IPS-like or IPS family. There are slight differences in colors, viewing angles, and contrast, but generally speaking, they"re all very similar.

There"s another display technology that"s growing in popularity: OLED. OLED, or organic light-emitting diode, is very different from the conventional LCD technology we"ve explored above. OLED panels are electro-emissive, which means each pixel emits its own light when it receives an electric signal, eliminating the need for a backlight. Since OLED panels can turn off individual pixels, they have deep, inky blacks with no blooming around bright objects. They also have excellent wide viewing angles, a near-instantaneous response time, and excellent gray uniformity.

Buying an impressive computer displays doesn’t have to be complicated or expensive. Browse our inventory of options based on group, activity, connections, resolution, aspect ratio, and more to find the best fit for your lifestyle. With the right monitor complementing your PC, you can fully realize its potential as a business, gaming, or everyday machine.

Trying to decide between all the types of displays, frames, and panels today’s modern computer monitor can offer? Here are a few common comparisons of monitor types that might help.

As monitor technology has evolved over the years, so have the types of inputs you’ll potentially use to connect your monitor to your PC and other devices. The most common way to connect your PC to your preferred display is by HDMI, but most modern monitors feature eitherHDMIorUSB Type-Cinput options to be easily compatible with today’s tech.

Many monitor manufacturers, including Lenovo, also still offerVGA displays. VGA is a more dated method of connecting your PC and visuals but there are still plenty of PCs around that may require this input method.

There are plenty of new and confusing terms facing TV shoppers today, but when it comes down to the screen technology itself, there are only two: Nearly every TV sold today is either LCD or OLED.

The biggest between the two is in how they work. With OLED, each pixel provides its own illumination so there"s no separate backlight. With an LCD TV, all of the pixels are illuminated by an LED backlight. That difference leads to all kinds of picture quality effects, some of which favor LCD, but most of which benefit OLED.

LCDs are made by a number of companies across Asia. All current OLED TVs are built by LG Display, though companies like Sony and Vizio buy OLED panels from LG and then use their own electronics and aesthetic design.

So which one is better? Read on for their strengths and weaknesses. In general we"ll be comparing OLED to the best (read: most expensive) LCD has to offer, mainly because there"s no such thing as a cheap OLED TV (yet).

The better LCDs have local dimming, where parts of the screen can dim independently of others. This isn"t quite as good as per-pixel control because the black areas still aren"t absolutely black, but it"s better than nothing. The best LCDs have full-array local dimming, which provides even finer control over the contrast of what"s onscreen -- but even they can suffer from "blooming," where a bright area spoils the black of an adjacent dark area.

One of the main downsides of LCD TVs is a change in picture quality if you sit away from dead center (as in, off to the sides). How much this matters to you certainly depends on your seating arrangement, but also on how much you love your loved ones.

A few LCDs use in-plane switching (IPS) panels, which have better off-axis picture quality than other kinds of LCDs, but don"t look as good as other LCDs straight on (primarily due to a lower contrast ratio).

OLED doesn"t have the off-axis issue LCDs have; its image looks basically the same, even from extreme angles. So if you have a wide seating area, OLED is the better option.

Nearly all current TVs are HDR compatible, but that"s not the entire story. Just because a TV claims HDR compatibility doesn"t mean it can accurately display HDR content. All OLED TVs have the dynamic range to take advantage of HDR, but lower-priced LCDs, especially those without local-dimming backlights, do not. So if you want to see HDR content it all its dynamic, vibrant beauty, go for OLED or an LCD with local dimming.

In our tests comparing the best new OLED and LCD TVs with HDR games and movies, OLED usually looks better. Its superior contrast and lack of blooming win the day despite LCD"s brightness advantage. In other words LCD TVs can get brighter, especially in full-screen bright scenes and HDR highlights, but none of them can control that illumination as precisely as an OLED TV.

The energy consumption of LCD varies depending on the backlight setting. The lower the backlight, the lower the power consumption. A basic LED LCD with its backlight set low will draw less power than OLED.

LG has said their OLED TVs have a lifespan of 100,000 hours to half brightness, a figure that"s similar to LED LCDs. Generally speaking, all modern TVs are quite reliable.

Does that mean your new LCD or OLED will last for several decades like your parent"s last CRT (like the one pictured). Probably not, but then, why would you want it to? A 42-inch flat panel cost $14,000 in the late 90"s, and now a 65-inch TV with more than 16x the resolution and a million times better contrast ratio costs $1,400. Which is to say, by the time you"ll want/need to replace it, there will be something even better than what"s available now, for less money.

OLED TVs are available in sizes from 48 to 88 inches, but LCD TVs come in smaller and larger sizes than that -- with many more choices in between -- so LCD wins. At the high end of the size scale, however, the biggest "TVs" don"t use either technology.

If you want something even brighter, and don"t mind spending a literal fortune to get it, Samsung, Sony, and LG all sell direct-view LED displays. In most cases these are

You can get 4K resolution, 50-inch LCDs for around $400 -- or half that on sale. It"s going to be a long time before OLEDs are that price, but they have come down considerably.

LCD dominates the market because it"s cheap to manufacture and delivers good enough picture quality for just about everybody. But according to reviews at CNET and elsewhere, OLED wins for overall picture quality, largely due to the incredible contrast ratio. The price difference isn"t as severe as it used to be, and in the mid- to high-end of the market, there are lots of options.

How big is big enough? When it comes to computer monitors, you want something that can fit comfortably on your desk while giving you plenty of screen real estate. While in the past sub-20-inch monitors were commonplace, today, unless you’re really constrained for space, there’s no real need to buy anything under 22 inches. For most, 24 inches is going to be a baseline, as you can pick up a number of screens at that size for around $100, and they look fantastic at 1080p.

Today, all the best screens are still LCD monitors that use LED technology for a slim product that saves energy while providing ideal backlighting. We’ve been waiting years for OLED technology to make the transition to PC monitors, it isfinally beginning thanks to brands like LG, but the technology is still relatively rare.

1080p: If you want reasonable clarity, but want to save on cost or focus on other, more important features, 1080p is where it’s at — as long as the monitor you’re buying isn’t extremely large. 1080p is ideal for 21-inch to 24-inch displays. These monitors offer great picture quality, and now that they are competing with 4K, the prices are rock-bottom. If you want to go larger than 24 inches, though, you should consider 2,560 x 1,440 resolution at the least and perhaps 4K.

1440p: The oft-forgotten stepchild in the gradual marriage of consumers and 4K, 1440p is still the suggested resolution for gamers, as it offers a noticeable improvement in visuals over 1080p but doesn’t overly tax your graphics card. It’s also far more affordable if you’re interested in extra features like high refresh rates. It is also commonly referred to as Quad HD/QHD.

5K:This resolution made headlines when Apple debuted it on its iMac, but it’s far from a common resolution even years later. Dell’s UP2715K is a great-looking display, but we would recommend many high-end 4K monitors before it, as you won’t be able to see too much difference between them.

While the above are the most common resolutions you’ll find on monitors, some fall into more niche categories. The best ultrawide monitors offer unique aspect ratios and resolutions with broad horizontal pixel counts, but less on the vertical dimension.

Aspect ratio: The aspect the screen shows images in (length compared to height). A common standard, and your best bet, is 16:9. It works with plenty of content, and it’s great for movies or games. Some fancy monitors like to stretch things out with ratios like 21:9, but that is more suitable for unusual work situations or hardcore gaming. Another common format, 16:10, provides slightly more vertical space for viewing multiple open documents or images. 3:2 is becoming more commonplace in laptops for better web viewing, but that’s rare on stand-alone displays.

Refresh rate: Rated in hertz (Hz), a monitor’s refresh rate is how often it updates the image on your screen. While most support up to 60Hz, some displays now offer much higher refresh rates. That can result in smoother movements on your desktop and support for higher frame rates in games, which can make a big difference in high-paced titles by reducing your input lag. 120Hz to 144Hz is a great range to target, but you could opt for the fastest screens out there with up to 240Hz support. Just make sure you have a high-powered graphics card to back it up.

TN: The most common panel type, Twisted Nematic (TN) displays offer good visuals and some of the fastest response times, making them great for gamers. But colors can look a little washed out, and viewing angles aren’t great. Displays with TN panels tend to be the most affordable.

IPS: Displays with IPS panels tend to be the most expensive of the bunch, but what you get for your money is much richer colors and clear viewing angles that are near horizontal. The downside of IPS panels is that they don’t tend to have as fast response times as TN displays, so some consider them inferior for gaming. There are, however, gaming IPS displays, like the fantastic Asus PG279Q, which make good ground on their TN counterparts. Some IPS monitors suffer from quality control issues, though, and most IPS displays have a telltale glow when displaying dark images due to backlight bleeding.

There are a few different ports you should look for on your monitor. Where VGA and DVI were standards of yesteryear, today, new displays ship with HDMI, DisplayPort, and USB-C connections most commonly. To make things more confusing, each of those has its own multitude of generations, which you need to be aware of if you’re planning on running a high-resolution or high refresh rate display.

The most common computer monitors are compact enough to sit on a table, desk, or stand. However, if you’re in the market for an enormous monitor, the most space-efficient choice is to mount the monitor onto a wall, thereby freeing up precious floor space. In this case, look for monitors thatcome with VESA standard mountingoptions or which are compatible with them. That way, you’ll have a larger selection of mounting arms from a variety of manufacturers to choose from, rather than being limited by specific mounting options.
