crt and lcd monitors brands
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).
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.

A CRT or cathode-ray tube monitor is a computer display that produces images using an electron gun. In the past, these types of monitors were the most popular screens for personal computers. They were considered state-of-the-art in their time but have been replaced by LCD monitors now.
In this article, I will discuss what a CRT monitor is, its pros and cons. I will also look at how it works, its benefits, and what to look for when buying one.
The cathode ray tube (CRT) was the display technology for computer monitors, televisions, calculators, and other electronic equipment prior to the introduction of flat panel displays, and, unfortunately, as monitors with lower resolutions may not be worth much to resell or refurbish them.
As CRT monitors are becoming more and more outdated, they are no longer widely used, especially with the rising popularity of flat panel displays using LCD and LED technology.
The old CRT monitor is being phased out from the market due to its bulky size and high energy consumption. The reason for the CRT monitor being bulky is that it has a cathode ray tube which is a very solid component of the monitor.
Because CRT monitors are analog, they are not able to display all the colors that come with digital technology. CRT monitors also have a lower refresh rate than modern LCD screens, which means that moving images will appear less smooth.
However, CRT monitors can still be found in most computer labs or tech businesses, as they have been used for years and can still meet the current need for a basic monitor.They have the advantage of being less expensive than other types of computer displays (see today"s top budget monitors).
CRT stands for cathode ray tube. They are called CRTs because the light that displays the images comes from an electron gun which creates a picture by generating streams of electrons with high-voltage differences.
A CRT computer monitor works by using an electron gun, which shoots out electrons at high speed. The electrons then collide with red, green, and blue phosphors that coat the inside of the screen. This process allows you to see the image on your monitor.
A CRT monitor is made up of many different parts that work together for optimal performance.The cabinet or casing of the monitor, often made out of plastic or metal, is where the heart of the monitor lies, containing the tube and plug-in boards.
CRTs, which stands for cathode ray tube, is a technology that was used in television and computer monitors for several decades. It was invented in 1897 by German scientist Karl Ferdinand Braun.
His CRT contained a cathode, a display surface made of glass coated with an opaque material, and a positively charged metal plate called the anode. Over the next few decades, CRTs made their way into the market due to their cost-effectiveness.
While it is not quite as popular as it was in the past, there are features of CRT monitors that many gamers, graphics designers,s, etc., would like to know, and they are;CRT monitors were the first displays available hence it is an old and outdated technology
You have to admit; CRT monitors were a great invention. They were big and beautiful. However, they were a bit bulky and made a fair bit of noise after some time. Here are their few advantages;
A new or old CRT is easy to use hence can be used very effectively by beginners without extensive training and yet at the same time be used quite easily by advanced users for work, gaming and so on.
When compared to LCDs, CRT monitors are very heavy with thick frames compared to today"s portable monitors, for example, making them impractical for travel.
Another disadvantage of this type of PC monitor is that it takes up a lot of space on your desk. Their big size takes up much of your desk space, making it hard for you to fit other things on top of it. Nowadays, this problem can easily be solved with curved monitors for more useful screen and work space.
CRTs use outdated technology, which sometimes produces images that have the blurry text and distorted colors. Purchasing a monitor with LCD technology will help avoid these problems.
These monitors are often not good gaming monitors or high-end photo editing because they don’t have the refresh rate needed to handle high-speed graphics without slowing down.
The picture projected by a CRT monitor is different than that of an LCD. The older technology of the CRT does not produce sharp and high-quality images due to its low resolution.
Their standard resolution is 640×480 pixels. Therefore, it is not the best for watching videos, streaming video content, or playing games. Also, some CRTs produce a lot of color distortion and slow response times, which leads to blurry graphics and ghosting on the screen.
The average price of CRTs is $50. However, you’ll find that they are less expensive than other types of computer monitors. There are several different places where you can buy a CRT. You can purchase it at a computer store, online, or you can even place an order at your local TV station.
There"s no secret to finding or buying a CRT monitor though you will need patience. The fastest and probably the best way to buy a CRT is eBay or Etsy. Hundreds of CRT computer monitors are available, including many that fit the recommendations of this guide.
The energy consumption of CRTs is higher than most other types of computer monitors. A 17-inch CRT monitor consumes 75 watts a day; this is according topower consumption calculators online.
Your CRT will last 8-10 years if you use the monitor eight hours a day. However, most CRT monitors sold in the last few years have 25,000 to 30,000-hour lifespans (see "How Long Do Monitors Last?" post).
Here are the best CRTs that are still on the market. The CRT displays that I have listed here have rich colors, some have an ergonomic design, are small screens to save your desktop space, have good resolution, and others have wide viewing angles of even160.ViewSonic PF790 Perfectly Flat 19" CRT
Buying a CRT can be tricky if you don"t know what to look for, i.e., features and qualities. This section will help you make the right choice whether you primarily want to use your monitor for work, gaming, or entertainment purposes.
The resolution of a CRT monitor measures in pixels per inch. The resolution, which is measured horizontally first, then vertically, can range from 600 to 2550 pixels on CRT displays.
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.
Refresh rates for a CRT monitor can reach up to 60 Hertz (Hz) or 75 Hz, which is significantly lower than what modern 120Hz or even 240Hz monitors offer. Lower numbers indicate a slower screen update, which could make your images look blurry. If you are using your CRT monitor for watching videos or playing games, choose a CRT for gaming with a refresh rate of above 60 Hz.
To avoid any problems, it is very important to check the size of the CRT monitor that you are about to buy. The majority of CRTs that are available in the market today come in sizes between 13 and 21 inches, which is really compact and small compared to 40-inch monitors of today.
Its popular sizes are 17 and 19 inches. A better computer display is one with a large screen. The bigger the display, the more you can see at once, thus reducing the need to scroll up and down web pages or work documents (see "What are the Best Monitors to Read Documents and Texts?" post).
Installing a new CRT is an easy task since it’s just setting it on your desktop and using the correct ports and cable to connect to your computer. Just plug one end of the cable into your computer and the other end directly into your monitor.
CRTs monitors become dirty because they are covered with dust, fingerprints, and grime that"s bonding on the screen. A little monitor cleaning once or twice a month will keep it as good as new.
Before starting to clean your computer monitor, turn off your monitor and unplug the power cable. Even with your computer turned off, there"s still some electrical current running through it; hence unplug its power cord before cleaning it.
First, connect your monitor to your PC via VGA or HDMI. Use a cable TV box or monitor to TV software to enable the monitor to display TV channels. With this, you will enjoy watching television on your monitor instead of on your old television set, cutting down on electricity costs and eliminating the need for cumbersome wires.
There is a common video input connection on most CRT (cathode ray tube) monitors and is VGA.A VGA port, or Video Graphics Array port, is an analog computer monitor connector that has been standard on personal computers for a long time. VGA carries a video signal in analog format.
There are various CRT problems that can cause monitors to display an image improperly. The most common ones include cracks and spots, discoloration, bad sound or no sound from the monitor, no image, etc.
This can be due to clogged speaker ports if dust and hair have gotten into the monitor"s internal components and plugged up the speaker ports or burned out speakers. Clean the speakers to solve the problem.
If you plan to buy a CRT, check it carefully for any signs of broken pixels or discoloration on the screen. If the monitor you choose has problems with discoloration, take it back immediately.
Yes, you can use a CRT computer monitor for gaming, but it is not the best. Some CRTs come with a good refresh rate of 60 HZ and 75 HZ, which are good for gaming. Monitors with this faster refresh rate will give smoother output with less blur and jumping.
Other CRTs come with high resolution, which is important for gaming. It"s what creates the definition in all those smoke trails and flame effects that make gaming so cool. The higher the resolution, the more you will be able to see clearly within games, like distant enemy movement.
CRTs work fine for old-fashioned businesses. However, they tend to be larger and bulkier while not coming with eye care technologies like anti-glare and flicker-free which are needed if you will be staring at the screen for hours.
LED monitors quickly replaced the CRT monitors. Given the fact that most CRT users have upgraded to LED, there is a strong concern of potential customers not being informed about this latest technological breakthrough.
There are 3 other types of monitors you will find when shopping for a new display for your computer, and each one is best suited for different use. They are;LED or light-emitting diode
If the CRT is broken or cracked, these materials may be released and pose a risk of toxic exposure. A charged CRT carries high voltage—about 27,000 volts in a color unit. You could electrocute yourself unless you handle the display using the appropriate safety procedures.
Respondents also provided the number of CRT units in their homes from none up to “4 or more.” Analysis of the results suggests there are approximately 77 million CRT TVs still in U.S. households and approximately 30 million CRT monitors.

In today’s digital world we are very have seen different types of monitors. We spend most of our time sitting in front of many types of monitors, like playing games, watching movies, and many other things.
Have you wondered which types of monitor are you using to watch TV and playing games? Well, All the 5 types of monitors I have mentioned in this article for you look at which monitor you are using. Let’s get to know.
A good display can be very effective in the user experience. The properties of display devices have also improved a lot due to the innovation in Display Technologies. There are many types of computer monitors available right now, in the case of CRT monitor and plasma maybe not.
LCD is known for‘Liquid Crystal Display’made of liquid crystals. It is the most used monitor worldwide, as it requires less space, consumes less electricity, and produces relatively less heat than an old CRT monitor.
This display was first used in laptops,and later the manufacturers also being produced for Desktop Computers range from 17 inches to 60 inches. Being these monitors need less space and are light in weight, they do not create any trouble in transporting and moving them from one place to another.
Both LCD and LED monitors have considerably more adaptability for positioning the screen in the manner in which you need it. These monitors can turn, tilt up and down, and even rotate from landscape to portrait mode.
LED’s full form is ‘Light Emitting Diode’ is the latest innovation in the market today’s market competing with LCDs and Plasma Monitors. These types of monitors are slightly curved or flat panel displays that use light-emitting diodes for backlighting on the screen instead of cold cathode fluorescent (CCFL) for back-lighting.
LED displays are more bright with 4k resolution than other displays, due to which the user can be read or seen easily in daylight time. LED monitors use less power than LCDs as well as LEDs are widely used by gamers for playing high graphics and HD games.
The advantage of LEDs is that they produce images with higher contrastand vivid colors as well as don’t make a negative impact on the environment at the time of disposing of. In addition, the LEDs are more durable as compared to LCD and CRT Monitors.
The wavelength range of lights utilized is such that to give high quality. These LEDs screen delivers flicker-free image which lessens the eye strain and fatigue, and headaches.
These kinds of monitors have a long life expectancy, use less power, and are thinner greater contrast and more vivid colors, and have a less environmental impact than LCDs.
The price rate of LED monitors can be a little expensive than TVs even after same sized, so they are not affordable for some people at which they are available in the market.
OLED stands for “Organic Light Emitting Diode“. As the name suggests, it is made of organic material (such as carbon, plastic, wood, and polymers), that is used to convert electric current into light.
This is also the latest display technology used in displays of television, computer screen, game consoles, PDAs, or even in the latest smartphones. It can be thinner or lighter with a higher contrast ratio than LCDs
Since these LEDs are capable enough to produce a lot of different colored light, can be used directly to produce the correct color and there is no need for any backlight, which saves power also requires less space. The OLED display is considered great for watching movies.
OLED Monitors are considered the best display technology ever because of their characteristics like wide viewing angles, picture quality, outstanding contrast levels, No ghosting, fast response, and perfect contrast and brightness.
Also, you should protect the monitor from water as it can damage the OLED screen. The other disadvantages of the OLED monitor right now are its short life expectancy than LCDs and LEDs and the high price rate in the market currently.
The basic idea behind its invention is that it illuminates the tiny colored fluorescent lights that create image pixels. Each pixel is made of three fluorescent lights like a tiny neon light-red, green, and blue lights. that produces a superior contrast ratio, along with the intensity of these lights also vary accordingly.
In addition, it has the advantage of slimness, a plasma display is flat rather than slightly curved as an LCDs has. It cuts down image distortion and glare through its perfect flat screens.
A plasma display offers a good response, superior performance, time, and a much wide viewing angle as compared to LCDs. Plasma displays come in sizes up to 60 inches that can be considered the best home theater and HD television.
The major disadvantages of plasma monitors are their limited production and screen sizes. Plasma monitors are heavier in size a well as consume more electricity, on average than LCD monitors.
Here CRT means “Cathode Ray Tube”. Its main part is the Cathode Ray tube which is called the “Generally Picture tube”. The above image is of the CRT monitor and was used a few decades ago as a desktop computer or to watching TV.
CRT monitors are much heavier in size as compared to LCD and LED monitors. Due to being heavy, they have much trouble while moving and transporting from one place to another. Also, they need more space for installation.
As they now disappeared from the market quickly in the last few decades, because display manufacturers switched their production lines from CRT 4:3 displays to LCD 16:9 widescreen displays in order to survive the transition to the digital world widescreen television of LEDs or LCDs.
This monochrome is made up of two words Mono (Single) and Chrome (Color), hence it is called Single Color Display and it displays the monitor’s output in Black & White colors.
These Gray-scale display monitors are similar to monochrome but it displays in gray shades. These types of computer monitors are mostly used in portable and hand computers such as laptops.
Color monitor displays the output with the adjustment of RGB (Red-Green-Blue) radiations. The theory of such monitors is capable of displaying graphics in high-resolution it can be 4k.
Full FormLCD is known for"Liquid Crystal Display."LED"s full form is "Light Emitting Diode."OLED stands for "Organic Light Emitting Diode".Plasma also known as PDP stands for "Plasma Display Panel".CRT stands for "Cathode Ray Tube".
Weight and SizeLCD monitors are compact in size and light in weight.LEDs are also compact in size and very light in weight.OLEDs are large in size and heavy in weight.Plasma monitors are also large in size and little bit heavy in weight.CRT monitors are bulky in size and very heavy in weight.
There are five types of monitors CRT(Cathode Ray tube), LCD (Liquid Crystal Display), LED (Liquid Emitting Diode), OLED (Organic Light Emitting Diode), and Plasma Monitor all are used in televisions or computer desktops.
The following are the five types of monitor: 1. LCD (Liquid Crystal Display), 2. LED (Liquid Emitting Diode), 3. OLED (Organic Light Emitting Diode), 4. CRT(Cathode Ray tube), and 5. Plasma Monitor.
LED displays are more bright with 4k resolution than other displays, due to which they can be read or seen easily in daylight time. LED monitors use less power than LCDs as well as LEDs are widely used by gamers for playing high graphics and HD games.
LCDs are much better than CRT monitors because they are much heavier in size as well as consume a lot of energy compared to LCD monitors. Due to being heavy, they have much trouble while moving and transporting from one place to another. Also, they need more space for installation.
Not at all, CRT monitors being older television sets. As they now disappeared from the market in the last few decades, because display manufacturers discontinued it and switched their production from CRT 4:3 displays to LCD 16:9 widescreen displays in order to survive the transition to the digital world widescreen television of LEDs or LCDs.

CRT displays use the same picture tube technology with many enhancements as the first color televisions did more than half a century ago. But old doesn"t necessarily mean obsolete. A good CRT display, such as the Samsung 997DF 19" model shown in Figure 11-1, provides excellent image quality at a reasonable price. CRT displays are an excellent choice for many people, and will remain so for years.
In autumn 2005, Robert finally replaced his beloved Hitachi SuperScan Elite 751 19" CRT display which he had been using as his primary display for six years with a 19" Samsung 930BF LCD display. The Hitachi is a top-notch display, and Robert would have sworn that its image quality was as good then as the day it was first installed. Until, that is, he connected the Samsung 930BF. The difference was startling. The Samsung provided much better brightness, contrast, and color saturation.
Does that mean that a good LCD display always beats a good CRT display, or that current display technology is worlds better than that of six years ago? Nope. It just means that every CRT display even the best models decreases in brightness, contrast, and saturation as it ages. From day to day, the difference is imperceptible, but as the months and years pass the accumulated difference becomes large.
There is a happy ending to this story, though. Robert had been running the Hitachi CRT at 50% brightness and 85% contrast for years. Boosting brightness to 75% and contrast to 100% greatly improved the display quality, so there"s life in it yet. Barbara promptly grabbed the Hitachi for her own office, where it will probably live for another few years.
The CRT is essentially a large glass bottle, flat or nearly so on one end (the screen), tapering to a thin neck at the back, and with nearly all air exhausted. The inside of the screen end is covered with a matrix of millions of tiny phosphor dots (or stripes). A phosphor is a chemical compound that, when struck by electrons, emits visible light of a particular color. Phosphors are organized by groups of three, collectively called a pixel. Each pixel contains one phosphor dot that emits each of the additive primary colors, red, green, and blue. By choosing which dots to illuminate and how brightly to illuminate each, any pixel can be made to emit any one of thousands or millions of discrete colors. The distance between nearest neighbors of the same phosphor color on adjacent rows is called the dot pitch or stripe pitch. A smaller pitch results in a sharper image and the ability to resolve finer detail.
The phosphor dots are excited by one or more electron emitters, called electron guns, located in the neck at the back of the monitor. A gun comprises a heated cathode, which emits electrons, and circuitry that focuses the free electrons into a thin beam.
The deflection yoke is located around the tapered portion of the CRT, between the guns and the screen. This yoke is actually a large electromagnet, which, under the control of the monitor circuitry, is used to steer the electron beam(s) to impinge on the correct phosphor dot at the correct time and with the correct intensity.
The mask sits between the electron guns and the phosphor layer, very close to the latter. This mask may be a sheet of metal with a matrix of fine perforations that correspond to the phosphor dot triads on the screen, called a shadow mask, or a series of fine vertical wires that correspond to phosphors laid down in uninterrupted vertical stripes, called an aperture grill. In practice, and despite the marketing efforts of manufacturers to convince us otherwise, we find that the mask type makes little real difference. Good (read: more expensive) monitors produce good images, regardless of their mask type. Inexpensive monitors produce inferior images, regardless of their mask type.
Screen size is specified in two ways. The nominal size the size by which monitors are advertised and referred to is the diagonal measurement of the tube itself. However, the front bezel of the monitor conceals part of the tube, making the usable size of the monitor less than stated. Various consumer lawsuits have resulted in monitor manufacturers also specifying the Viewable Image Size (VIS), which is the portion of the tube that is actually visible. Typically, VIS is an inch or so less than nominal. For example, a nominal 17" monitor may have a 15.8" VIS. Small differences in VIS for example, 15.8" versus 16" make little practical difference. The smallest monitors still available are 15". While 17" remains the most popular size, 19" models are now so inexpensive that they have nearly overtaken 17" models in unit sales. Monitors 21" and larger are still relatively expensive, and are used primarily by graphics artists and others who require huge displays.
Dot pitch or stripe pitch is measured in millimeters, and specifies the center-to-center distance between the nearest neighboring phosphor dots or stripes of the same color. Smaller pitch means a sharper image that resolves finer detail. Unfortunately, dot pitch, which is used to describe shadow mask monitors, cannot be compared directly to stripe pitch, which is used to describe aperture grill monitors. For equivalent resolution, stripe pitch must be about 90% of dot pitch. That is, a 0.28 mm dot pitch monitor has resolution similar to a 0.25 mm stripe pitch monitor.
Maximum resolution specifies the maximum number of pixels that the monitor can display, which is determined by the physical number of pixels present on the face of the tube. The maximum resolution of many low-end monitors is identical to the optimum resolution for that monitor size. For example, 1024x768 is optimum for 17" monitors, so many low-end 17" monitors provide 1024x768 maximum resolution. Conversely, midrange and high-end monitors may have maximum resolutions higher than practically usable. For example, a high-end 17" monitor may support up to 1600x1200. There is no real benefit to such extreme resolutions, although it can be useful to have one step higher than optimum (e.g., 1280x1024 on a 17" monitor or 1600x1200 on a 19" monitor) available for occasional use for special purposes.
The synchronization range specifies the bandwidth of the monitor, which determines which combinations of resolution, refresh rate, and color depth can be displayed. Synchronization range is specified as two values:
Vertical Scanning Frequency (VSF) is the inverse of the time the monitor requires to display one full screen. VSF (also called refresh rate) is measured in hertz (Hz) and specifies the number of times per second the screen can be redrawn. To avoid screen flicker, the monitor should support at least 70 Hz refresh at the selected resolution. Within reason, higher refresh rates provide a more stable image, but rates beyond 85 or 90 Hz are necessary only for specialized applications such as medical imaging. Most monitors support a wide range of refresh rates, from very low (e.g., 50 Hz) to very high (e.g., 120 to 160 Hz).
Horizontal Scanning Frequency (HSF) is the inverse of the time the monitor requires to display one full scan line. HSF is measured in kilohertz (KHz), and specifies the overall range of bandwidths supported by the monitor. For example, a monitor running 1280x1024 at 85 Hz must display 1024 lines 85 times per second, or 87,040 scan lines per second, or about 87 KHz. In fact, some overhead is involved, so the actual HSF for such a monitor might be 93.5 KHz.
Resolution and refresh rate are interrelated parts of synchronization range of an analog monitor. For a given resolution, increasing the refresh rate increases the number of screens (and accordingly the amount of data) that must be transferred each second. Similarly, for a given refresh rate, increasing the resolution increases the amount of data that must be transferred for each screen. If you increase resolution or refresh rate, you may have to decrease the other to stay within the HSF limit on total bandwidth.
Note that manufacturers often specify maximum resolution and maximum refresh rate independently, without consideration for their interrelatedness. For example, specifications for a 19" monitor may promise 1600x1200 resolution and 160 Hz refresh. Don"t assume that means you can run 1600x1200 at 160 Hz. 160 Hz refresh may be supported only at 640x480 resolution; at 1600x1200, the monitor may support only 70 Hz refresh.
Resolution and refresh rate alone determine the required bandwidth for an analog monitor. Color depth is immaterial, because the color displayed for a given pixel is determined by the analog voltages present on the red, green, and blue lines at the time that pixel is processed. Therefore, at a given resolution and refresh rate, an analog monitor uses exactly the same bandwidth whether the color depth is set to 4, 8, 16, 24, or 32 bits, because the video card converts the digital color data to analog signals before sending it to the monitor. For purely digital monitors, such as LCD displays, greater color depth requires greater bandwidth, because color information is conveyed to a digital monitor as a digital signal.
Monitors use one of three geometries for the front viewing surface. Older monitors used spherical tubes or cylindrical tubes, both of which have noticeably curved surfaces. Flat square tubes (FST) are nearly flat. Other than some "value" models, all current monitors use an FST. Don"t consider buying a monitor that is not FST.
CRTs cost less than LCDs. For the same price as an entry-level 17" LCD, you can buy a midrange 19" CRT or two good 17" CRTs. The pricing differential has somewhat narrowed recently, but LCDs are likely for the foreseeable future to cost more than CRTs with similar size, features, and quality.
LCDs are designed to operate at one resolution, typically 1024x768 for 15" models and 1280x1024 for 17", 18", and 19" models. Although you can run an LCD at lower resolution than it was designed to use, you don"t want to. At nonnative resolution, you must choose between having a sharp image that occupies only a portion of the screen or using pixel extrapolation, which results in a full-screen image with significantly degraded image quality. CRTs, conversely, can operate at various resolutions, which means that you can choose the resolution that suits your own preferences and vision.
A high-quality CRT normally lasts for many years. It"s common for a CRT to remain in use for five years or more, and even ten years is not unheard of. LCDs use an array of cold cathode ray tubes (CCRTs), which are similar to fluorescent tubes, to provide the backlight required to view the image. A failed CCRT is not economically repairable. When a CCRT burns out, the LCD display must be replaced.
CRTs use phosphor pixels, which can be turned on or off almost instantly. LCDs use transistorized pixels that respond more slowly. This slower response may be visible as a smearing or ghosting effect when an LCD displays fast-motion video, such as DVD video or graphics-intensive games. Although better LCDs don"t exhibit this problem, at least not as severely as cheaper models, it is common and intrusive with entry-level LCDs.
CRTs present essentially the same image quality regardless of viewing angle. Conversely, LCDs present their best image quality only within a relatively small viewing angle, although midrange and better LCD models typically have larger viewing angles than entry-level models.
Many graphic artists refuse to use LCDs because the appearance of colors and the relationship between them changes with viewing angle. This problem is particularly acute with inexpensive LCDs, although even premium units exhibit it at least to some extent. The best LCD models are good enough in this respect for routine use, but most who insist on accurate color reproduction still prefer high-quality CRT monitors.
A CRT never has defective pixels. An LCD panel is manufactured as a monolithic item that contains more than a million pixels, and on some LCD panels one or a few of those pixels are defective. Defective pixels may be always-on (white), always-off (black), or some color. People vary in their reaction to defective pixels. Many don"t even notice a defective pixel or two, while others, once they notice a defective pixel, seem to be drawn to that pixel to the exclusion of all else. Most manufacturer warranties specifically exclude some number of defective pixels, typically between five and ten, although the number may vary with display size and, sometimes, with the location of the defective pixels and how closely they are clustered. As long as the display meets those requirements, the manufacturer considers the display to be acceptable. You may or may not find it acceptable.
Although the contrast and brightness of recent high-end LCDs are excellent, most LCDs provide subjectively less vibrant color than a good CRT. This is particularly evident in the darkest and lightest areas, where tones seem to be compressed, which limits subtle gradations between light tones or dark tones that are readily evident on a good CRT. Also, some LCDs add a color cast to what should be neutral light or dark tones. For example, dark neutral tones may appear shifted toward the blue (cooler) or red (warmer) ranges. This problem is less prevalent in high-quality LCDs than in entry-level units, and is also more likely to occur if you are using an analog interface rather than a digital interface.
If your budget is limited, a CRT offers far more bang for the buck than an LCD and, particularly for entry-level models, overall display quality will also be higher.
Remember that a CRT display is a long-term purchase. Even with heavy use, a high-quality CRT can be expected to last five years or more, so buy quality and choose a model that"s likely to keep you happy not just for your current system, but for one or even two systems after that.
Make sure the CRT is big enough, but not too big. We consider 17" models suitable only for casual use or those on the tightest of budgets. For not much more, you can buy a 19" model that you"ll be much happier with. Conversely, make sure your desk or workstation furniture can accommodate the new CRT. Many people have excitedly carried home a new 21" CRT only to find that it literally won"t fit where it needs to. Check physical dimensions and weight carefully before you buy. Large CRTs commonly weigh 50 lbs. or more, and some exceed 100 lbs. That said, if you find yourself debating 17" versus 19" or 19" versus 21", go with the larger model. But note that if your decision is between a cheap larger CRT and a high-quality smaller one for about the same price, you may well be happier with the smaller CRT. A $130 17" CRT beats a $130 19" CRT every time.
Stick with good name brands and buy a midrange or higher model from within that name brand. That doesn"t guarantee that you"ll get a good CRT, but it does greatly increase your chances. The CRT market is extremely competitive. If two similar models differ greatly in price, the cheaper one likely has significantly worse specs. If the specs appear similar, the maker of the cheaper model has cut corners somewhere, whether in component quality, construction quality, or warranty policies.
RECOMMENDED BRANDS Our opinion, which is shared by many, is that NEC-Mitsubishi, Samsung, and ViewSonic make the best CRTs available. Their CRTs, particularly midrange and better models, provide excellent image quality and are quite reliable. You"re likely to be happy with a CRT from any of these manufacturers.
If possible, test the exact CRT you plan to buy (not a floor sample) before you buy it. Ask the local store to endorse the manufacturer"s warranty that is, to agree that if the CRT fails you can bring it back to the store for a replacement rather than dealing with the hassles of returning it to the manufacturer. Mass merchandisers like Best Buy usually won"t do this they try to sell you a service contract instead, which you shouldn"t buy but small local computer stores may agree to endorse the manufacturer"s warranty. If the CRT has hidden damage from rough handling during shipping, that damage will ordinarily be apparent within a month or two of use, if not immediately.
BUY CRTS LOCALLY After shipping costs, it may actually cost less to buy locally, but that is not the main reason for doing so. Buying locally gives you the opportunity to examine the exact CRT you are buying. CRTs vary more between samples than other computer components. Also, CRTs are sometimes damaged in shipping, often without any external evidence on the CRT itself or even the box. Damaged CRTs may arrive DOA, but more often they have been jolted severely enough to cause display problems and perhaps reduced service life, but not complete failure. Buying locally allows you to eliminate a "dud" before you buy it, rather than having to deal with shipping it back to the vendor or manufacturer.
Most mainstream CRT manufacturers produce three Good, Better, and Best models in 17", 19", and 21". In general, the Good model from a first-tier maker corresponds roughly in features, specifications, and price to the Better or Best models from lower-tier makers. For casual use, choose a Good model from a first-tier maker, most of which are very good indeed. If you make heavier demands on your CRT such as sitting in front of it eight hours a day you may find that the Better model from a first-tier maker is the best choice. The Best models from first-tier makers are usually overkill, although they may be necessary if you use the CRT for CAD/CAM or other demanding tasks. Best models often have generally useless features like extremely high resolutions and unnecessarily high refresh rates at moderate resolutions. It"s nice that a Best 17" model can display 1600x1200 resolution, for example, but unless you can float on thermals and dive on rabbits from a mile in the air, that resolution is likely to be unusable. Similarly, a 17" CRT that supports 115 MHz refresh rates at 1024x768 is nice, but in practical terms offers no real advantage over one that supports an 85 or 90 MHz refresh.
Choose the specific CRT you buy based on how it looks to you. Comparing specifications helps narrow the list of candidates, but nothing substitutes for actually looking at the image displayed by the CRT. For example, CRTs with Sony Trinitron tubes have one or two fine horizontal internal wires whose shadows appear on screen. Most people don"t even notice the shadow, but some find it intolerable.
Make sure the CRT has sufficient reserve brightness. CRTs dim as they age, and one of the most common flaws in new CRTs, particularly those from second- and third-tier manufacturers, is inadequate brightness. A CRT that is barely bright enough when new may dim enough to become unusable after a year or two. A new CRT should provide a good image with the brightness set no higher than 50%.
Like all other component manufacturers, CRT makers have come under increasing margin pressures. A few years ago, we felt saf
