A cathode-ray tube (CRT) is a vacuum tube containing one or more electron guns, which emit electron beams that are manipulated to display images on a phosphorescent screen.waveforms (oscilloscope), pictures (television set, computer monitor), radar targets, or other phenomena. A CRT on a television set is commonly called a picture tube. CRTs have also been used as memory devices, in which case the screen is not intended to be visible to an observer. The term

In CRT television sets and computer monitors, the entire front area of the tube is scanned repeatedly and systematically in a fixed pattern called a raster. In color devices, an image is produced by controlling the intensity of each of three electron beams, one for each additive primary color (red, green, and blue) with a video signal as a reference.magnetic deflection, using a deflection yoke. Electrostatic deflection is commonly used in oscilloscopes.

Since the mid-late 2000"s, CRTs have been superseded by flat-panel display technologies such as LCD, plasma display, and OLED displays which are cheaper to manufacture and run, as well as significantly lighter and less bulky. Flat-panel displays can also be made in very large sizes whereas 40 in (100 cm) to 45 in (110 cm)

Cathode rays were discovered by Julius Plücker and Johann Wilhelm Hittorf.cathode (negative electrode) which could cast shadows on the glowing wall of the tube, indicating the rays were traveling in straight lines. In 1890, Arthur Schuster demonstrated cathode rays could be deflected by electric fields, and William Crookes showed they could be deflected by magnetic fields. In 1897, J. J. Thomson succeeded in measuring the charge-mass-ratio of cathode rays, showing that they consisted of negatively charged particles smaller than atoms, the first "subatomic particles", which had already been named George Johnstone Stoney in 1891. The earliest version of the CRT was known as the "Braun tube", invented by the German physicist Ferdinand Braun in 1897.cold-cathode diode, a modification of the Crookes tube with a phosphor-coated screen. Braun was the first to conceive the use of a CRT as a display device.

The first cathode-ray tube to use a hot cathode was developed by John Bertrand Johnson (who gave his name to the term Johnson noise) and Harry Weiner Weinhart of Western Electric, and became a commercial product in 1922.

In 1926, Kenjiro Takayanagi demonstrated a CRT television receiver with a mechanical video camera that received images with a 40-line resolution.Philo Farnsworth created a television prototype.Vladimir K. Zworykin.: 84 RCA was granted a trademark for the term (for its cathode-ray tube) in 1932; it voluntarily released the term to the public domain in 1950.

In 1947, the cathode-ray tube amusement device, the earliest known interactive electronic game as well as the first to incorporate a cathode-ray tube screen, was created.

In the mid-2000s, Canon and Sony presented the surface-conduction electron-emitter display and field-emission displays, respectively. They both were flat-panel displays that had one (SED) or several (FED) electron emitters per subpixel in place of electron guns. The electron emitters were placed on a sheet of glass and the electrons were accelerated to a nearby sheet of glass with phosphors using an anode voltage. The electrons were not focused, making each subpixel essentially a flood beam CRT. They were never put into mass production as LCD technology was significantly cheaper, eliminating the market for such displays.

Beginning in the late 90s to the early 2000s, CRTs began to be replaced with LCDs, starting first with computer monitors smaller than 15 inches in size,Hitachi in 2001,Flat-panel displays dropped in price and started significantly displacing cathode-ray tubes in the 2000s. LCD monitor sales began exceeding those of CRTs in 2003–2004

Despite being a mainstay of display technology for decades, CRT-based computer monitors and televisions are now virtually a dead technology. Demand for CRT screens dropped in the late 2000s.

A popular consumer usage of CRTs is for retrogaming. Some games are impossible to play without CRT display hardware, and some games play better. Reasons for this include:

The design of the high voltage power supply in a product using a CRT has an influence in the amount of x-rays emitted by the CRT. The amount of emitted x-rays increases with both higher voltages and currents. If the product such as a TV set uses an unregulated high voltage power supply, meaning that anode and focus voltage go down with increasing electron current when displaying a bright image, the amount of emitted x-rays is as its highest when the CRT is displaying a moderately bright images, since when displaying dark or bright images, the higher anode voltage counteracts the lower electron beam current and vice versa respectively. The high voltage regulator and rectifier vacuum tubes in some old CRT TV sets may also emit x-rays.

Since it is a hot cathode, it is prone to cathode poisoning, which is the formation of a positive ion layer that prevents the cathode from emitting electrons, reducing image brightness significantly or completely and causing focus and intensity to be affected by the frequency of the video signal preventing detailed images from being displayed by the CRT. The positive ions come from leftover air molecules inside the CRT or from the cathode itself

Burn-in is when images are physically "burned" into the screen of the CRT; this occurs due to degradation of the phosphors due to prolonged electron bombardment of the phosphors, and happens when a fixed image or logo is left for too long on the screen, causing it to appear as a "ghost" image or, in severe cases, also when the CRT is off. To counter this, screensavers were used in computers to minimize burn-in.

Various phosphors are available depending upon the needs of the measurement or display application. The brightness, color, and persistence of the illumination depends upon the type of phosphor used on the CRT screen. Phosphors are available with persistences ranging from less than one microsecond to several seconds.

Doming is a phenomenon found on some CRT televisions in which parts of the shadow mask become heated. In televisions that exhibit this behavior, it tends to occur in high-contrast scenes in which there is a largely dark scene with one or more localized bright spots. As the electron beam hits the shadow mask in these areas it heats unevenly. The shadow mask warps due to the heat differences, which causes the electron gun to hit the wrong colored phosphors and incorrect colors to be displayed in the affected area.

Aperture grille screens are brighter since they allow more electrons through, but they require support wires. They are also more resistant to warping.

CRT monitors can still outperform LCD and OLED monitors in input lag, as there is no signal processing between the CRT and the display connector of the monitor, since CRT monitors often use VGA which provides an analog signal that can be fed to a CRT directly. Video cards designed for use with CRTs may have a RAMDAC to generate the analog signals needed by the CRT.multisyncing.

Picture tube CRTs have overscan, meaning the actual edges of the image are not shown; this is deliberate to allow for adjustment variations between CRT TVs, preventing the ragged edges (due to blooming) of the image from being shown on screen. The shadow mask may have grooves that reflect away the electrons that do not hit the screen due to overscan.

A shadow mask tube uses a metal plate with tiny holes, typically in a delta configuration, placed so that the electron beam only illuminates the correct phosphors on the face of the tube;aperture grille of tensioned vertical wires to achieve the same result.

Due to limitations in the dimensional precision with which CRTs can be manufactured economically, it has not been practically possible to build color CRTs in which three electron beams could be aligned to hit phosphors of respective color in acceptable coordination, solely on the basis of the geometric configuration of the electron gun axes and gun aperture positions, shadow mask apertures, etc. The shadow mask ensures that one beam will only hit spots of certain colors of phosphors, but minute variations in physical alignment of the internal parts among individual CRTs will cause variations in the exact alignment of the beams through the shadow mask, allowing some electrons from, for example, the red beam to hit, say, blue phosphors, unless some individual compensation is made for the variance among individual tubes.

The solution to the static convergence and purity problems is a set of color alignment ring magnets installed around the neck of the CRT.magnetic fields parallel to the planes of the magnets, which are perpendicular to the electron gun axes. Often, one ring has two poles, another has 4, and the remaining ring has 6 poles.vector can be fully and freely adjusted (in both direction and magnitude). By rotating a pair of magnets relative to each other, their relative field alignment can be varied, adjusting the effective field strength of the pair. (As they rotate relative to each other, each magnet"s field can be considered to have two opposing components at right angles, and these four components [two each for two magnets] form two pairs, one pair reinforcing each other and the other pair opposing and canceling each other. Rotating away from alignment, the magnets" mutually reinforcing field components decrease as they are traded for increasing opposed, mutually cancelling components.) By rotating a pair of magnets together, preserving the relative angle between them, the direction of their collective magnetic field can be varied. Overall, adjusting all of the convergence/purity magnets allows a finely tuned slight electron beam deflection or lateral offset to be applied, which compensates for minor static convergence and purity errors intrinsic to the uncalibrated tube. Once set, these magnets are usually glued in place, but normally they can be freed and readjusted in the field (e.g. by a TV repair shop) if necessary.

The convergence signal may instead be a sawtooth signal with a slight sine wave appearance, the sine wave part is created using a capacitor in series with each deflection coil. In this case, the convergence signal is used to drive the deflection coils. The sine wave part of the signal causes the electron beam to move more slowly near the edges of the screen. The capacitors used to create the convergence signal are known as the s-capacitors. This type of convergence is necessary due to the high deflection angles and flat screens of many CRT computer monitors. The value of the s-capacitors must be chosen based on the scan rate of the CRT, so multi-syncing monitors must have different sets of s-capacitors, one for each refresh rate.

Dynamic color convergence and purity are one of the main reasons why until late in their history, CRTs were long-necked (deep) and had biaxially curved faces; these geometric design characteristics are necessary for intrinsic passive dynamic color convergence and purity. Only starting around the 1990s did sophisticated active dynamic convergence compensation circuits become available that made short-necked and flat-faced CRTs workable. These active compensation circuits use the deflection yoke to finely adjust beam deflection according to the beam target location. The same techniques (and major circuit components) also make possible the adjustment of display image rotation, skew, and other complex raster geometry parameters through electronics under user control.

Color CRT displays in television sets and computer monitors often have a built-in degaussing (demagnetizing) coil mounted around the perimeter of the CRT face. Upon power-up of the CRT display, the degaussing circuit produces a brief, alternating current through the coil which fades to zero over a few seconds, producing a decaying alternating magnetic field from the coil. This degaussing field is strong enough to remove shadow mask magnetization in most cases, maintaining color purity.deform (bend) the shadow mask, causing a permanent color distortion on the display which looks very similar to a magnetization effect.

Dot pitch defines the maximum resolution of the display, assuming delta-gun CRTs. In these, as the scanned resolution approaches the dot pitch resolution, moiré appears, as the detail being displayed is finer than what the shadow mask can render.

Beam-index tubes, also known as Uniray, Apple CRT or Indextron,Philco to create a color CRT without a shadow mask, eliminating convergence and purity problems, and allowing for shallower CRTs with higher deflection angles.

Flat CRTs are those with a flat screen. Despite having a flat screen, they may not be completely flat, especially on the inside, instead having a greatly increased curvature. A notable exception is the LG Flatron (made by LG.Philips Displays, later LP Displays) which is truly flat on the outside and inside, but has a bonded glass pane on the screen with a tensioned rim band to provide implosion protection. Such completely flat CRTs were first introduced by Zenith in 1986, and used

flat tensioned shadow masks, where the shadow mask is held under tension, providing increased resistance to blooming.TV80, and in many Sony Watchmans were flat in that they were not deep and their front screens were flat, but their electron guns were put to a side of the screen.

Radar CRTs such as the 7JP4 had a circular screen and scanned the beam from the center outwards. The screen often had two colors, often a bright short persistence color that only appeared as the beam scanned the display and a long persistence phosphor afterglow. When the beam strikes the phosphor, the phosphor brightly illuminates, and when the beam leaves, the dimmer long persistence afterglow would remain lit where the beam struck the phosphor, alongside the radar targets that were "written" by the beam, until the beam re-struck the phosphor.

In oscilloscope CRTs, electrostatic deflection is used, rather than the magnetic deflection commonly used with television and other large CRTs. The beam is deflected horizontally by applying an electric field between a pair of plates to its left and right, and vertically by applying an electric field to plates above and below. Televisions use magnetic rather than electrostatic deflection because the deflection plates obstruct the beam when the deflection angle is as large as is required for tubes that are relatively short for their size. Some Oscilloscope CRTs incorporate post deflection anodes (PDAs) that are spiral-shaped to ensure even anode potential across the CRT and operate at up to 15,000 volts. In PDA CRTs the electron beam is deflected before it is accelerated, improving sensitivity and legibility, specially when analyzing voltage pulses with short duty cycles.

When displaying fast one-shot events, the electron beam must deflect very quickly, with few electrons impinging on the screen, leading to a faint or invisible image on the display. Oscilloscope CRTs designed for very fast signals can give a brighter display by passing the electron beam through a micro-channel plate just before it reaches the screen. Through the phenomenon of secondary emission, this plate multiplies the number of electrons reaching the phosphor screen, giving a significant improvement in writing rate (brightness) and improved sensitivity and spot size as well.

Most oscilloscopes have a graticule as part of the visual display, to facilitate measurements. The graticule may be permanently marked inside the face of the CRT, or it may be a transparent external plate made of glass or acrylic plastic. An internal graticule eliminates parallax error, but cannot be changed to accommodate different types of measurements.

Where a single brief event is monitored by an oscilloscope, such an event will be displayed by a conventional tube only while it actually occurs. The use of a long persistence phosphor may allow the image to be observed after the event, but only for a few seconds at best. This limitation can be overcome by the use of a direct view storage cathode-ray tube (storage tube). A storage tube will continue to display the event after it has occurred until such time as it is erased. A storage tube is similar to a conventional tube except that it is equipped with a metal grid coated with a dielectric layer located immediately behind the phosphor screen. An externally applied voltage to the mesh initially ensures that the whole mesh is at a constant potential. This mesh is constantly exposed to a low velocity electron beam from a "flood gun" which operates independently of the main gun. This flood gun is not deflected like the main gun but constantly "illuminates" the whole of the storage mesh. The initial charge on the storage mesh is such as to repel the electrons from the flood gun which are prevented from striking the phosphor screen.

When the main electron gun writes an image to the screen, the energy in the main beam is sufficient to create a "potential relief" on the storage mesh. The areas where this relief is created no longer repel the electrons from the flood gun which now pass through the mesh and illuminate the phosphor screen. Consequently, the image that was briefly traced out by the main gun continues to be displayed after it has occurred. The image can be "erased" by resupplying the external voltage to the mesh restoring its constant potential. The time for which the image can be displayed was limited because, in practice, the flood gun slowly neutralises the charge on the storage mesh. One way of allowing the image to be retained for longer is temporarily to turn off the flood gun. It is then possible for the image to be retained for several days. The majority of storage tubes allow for a lower voltage to be applied to the storage mesh which slowly restores the initial charge state. By varying this voltage a variable persistence is obtained. Turning off the flood gun and the voltage supply to the storage mesh allows such a tube to operate as a conventional oscilloscope tube.

The Williams tube or Williams-Kilburn tube was a cathode-ray tube used to electronically store binary data. It was used in computers of the 1940s as a random-access digital storage device. In contrast to other CRTs in this article, the Williams tube was not a display device, and in fact could not be viewed since a metal plate covered its screen.

In some vacuum tube radio sets, a "Magic Eye" or "Tuning Eye" tube was provided to assist in tuning the receiver. Tuning would be adjusted until the width of a radial shadow was minimized. This was used instead of a more expensive electromechanical meter, which later came to be used on higher-end tuners when transistor sets lacked the high voltage required to drive the device.

Some displays for early computers (those that needed to display more text than was practical using vectors, or that required high speed for photographic output) used Charactron CRTs. These incorporate a perforated metal character mask (stencil), which shapes a wide electron beam to form a character on the screen. The system selects a character on the mask using one set of deflection circuits, but that causes the extruded beam to be aimed off-axis, so a second set of deflection plates has to re-aim the beam so it is headed toward the center of the screen. A third set of plates places the character wherever required. The beam is unblanked (turned on) briefly to draw the character at that position. Graphics could be drawn by selecting the position on the mask corresponding to the code for a space (in practice, they were simply not drawn), which had a small round hole in the center; this effectively disabled the character mask, and the system reverted to regular vector behavior. Charactrons had exceptionally long necks, because of the need for three deflection systems.

Nimo was the trademark of a family of small specialised CRTs manufactured by Industrial Electronic Engineers. These had 10 electron guns which produced electron beams in the form of digits in a manner similar to that of the charactron. The tubes were either simple single-digit displays or more complex 4- or 6- digit displays produced by means of a suitable magnetic deflection system. Having little of the complexities of a standard CRT, the tube required a relatively simple driving circuit, and as the image was projected on the glass face, it provided a much wider viewing angle than competitive types (e.g., nixie tubes).

Flood-beam CRTs are small tubes that are arranged as pixels for large video walls like Jumbotrons. The first screen using this technology (called Diamond Vision by Mitsubishi Electric) was introduced by Mitsubishi Electric for the 1980 Major League Baseball All-Star Game. It differs from a normal CRT in that the electron gun within does not produce a focused controllable beam. Instead, electrons are sprayed in a wide cone across the entire front of the phosphor screen, basically making each unit act as a single light bulb.light-emitting diode displays. Unfocused and undeflected CRTs were used as grid-controlled stroboscope lamps since 1958.Electron-stimulated luminescence (ESL) lamps, which use the same operating principle, were released in 2011.

In the late 1990s and early 2000s Philips Research Laboratories experimented with a type of thin CRT known as the Zeus display, which contained CRT-like functionality in a flat-panel display.

Some CRT manufacturers, both LG.Philips Displays (later LP Displays) and Samsung SDI, innovated CRT technology by creating a slimmer tube. Slimmer CRT had the trade names Superslim,

At low refresh rates (60 Hz and below), the periodic scanning of the display may produce a flicker that some people perceive more easily than others, especially when viewed with peripheral vision. Flicker is commonly associated with CRT as most televisions run at 50 Hz (PAL) or 60 Hz (NTSC), although there are some 100 Hz PAL televisions that are flicker-free. Typically only low-end monitors run at such low frequencies, with most computer monitors supporting at least 75 Hz and high-end monitors capable of 100 Hz or more to eliminate any perception of flicker.sonar or radar may have long persistence phosphor and are thus flicker free. If the persistence is too long on a video display, moving images will be blurred.

This problem does not occur on 100/120 Hz TVs and on non-CGA (Color Graphics Adapter) computer displays, because they use much higher horizontal scanning frequencies that produce sound which is inaudible to humans (22 kHz to over 100 kHz).

High vacuum inside glass-walled cathode-ray tubes permits electron beams to fly freely—without colliding into molecules of air or other gas. If the glass is damaged, atmospheric pressure can collapse the vacuum tube into dangerous fragments which accelerate inward and then spray at high speed in all directions. Although modern cathode-ray tubes used in televisions and computer displays have epoxy-bonded face-plates or other measures to prevent shattering of the envelope, CRTs must be handled carefully to avoid personal injury.

Under some circumstances, the signal radiated from the electron guns, scanning circuitry, and associated wiring of a CRT can be captured remotely and used to reconstruct what is shown on the CRT using a process called Van Eck phreaking.TEMPEST shielding can mitigate this effect. Such radiation of a potentially exploitable signal, however, occurs also with other display technologies

As electronic waste, CRTs are considered one of the hardest types to recycle.phosphors, both of which are necessary for the display. There are several companies in the United States that charge a small fee to collect CRTs, then subsidize their labor by selling the harvested copper, wire, and printed circuit boards. The United States Environmental Protection Agency (EPA) includes discarded CRT monitors in its category of "hazardous household waste"

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.

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.

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.

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.

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.

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.

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

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.

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 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

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

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.

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).

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.

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.

Behind a nondescript Manhattan storefront, Chi-Tien Lui is stockpiling objects many people wouldn’t think twice about trashing: cathode ray tube televisions. The first floor of CTL Electronics — whose clientele includes the Museum of Modern Art, the Whitney, and other museums across the country — is lined with a rich mix of vintage TVs, from tiny boxes to big, looming screens. In his bedroom upstairs, Lui has a 1930s mechanical television, an early image transmission system that passed light through a spinning metal disc. In his workshop, there’s a grid of old screens that once sat inside the Palladium, an iconic New York nightclub that closed in 1997. “They used to have 16 of these, rotating in the club — everybody danced underneath,” Lui recalls. “When they went out of business I took all the equipment back. And right now, I’m restoring them.”

CRTs were once synonymous with television. By 1960, nearly 90 percent of American households had one. But at the turn of the millennium, their popularity rapidly decayed as LCD panels flooded the market. Even though CRTs comprised an estimated 85 percent of US television sales in 2003, analysts were already predicting the technology’s demise. In 2008, LCD panels outsold CRTs worldwide for the first time. Sony shut down its last manufacturing plants that same year, essentially abandoning its famous Trinitron CRT brand. By 2014, even stronghold markets like India were fading, with local manufacturers switching to flat-panel displays.

Despite all this, picture tube televisions continue to linger. You’ll find them in museums, arcades, video game tournaments, and the homes of dedicated fans. But as the CRT slips further into obsolescence, devotees like Lui are navigating a difficult transition between simply maintaining an aging device and preserving a piece of technological history.

The concept of television predates the electronic CRT display by decades. Scholar Alexander Magoun’s book Television: The Life Story of a Technology describes it as a natural extension of the telegram, fax machine, and telephone. In 1879, a cartoonist envisioned families communicating across continents via a wall-mounted “telephonoscope.” In the 1880s, German inventor Paul Nipkow imagined capturing slices of an image through holes in a spinning disk, then projecting the light patterns through an identical disk on the other end. Russian scientist Constantin Perskyi reported on this new theory of “television by means of electricity” at the 1900 Paris world’s fair, coining the term that we still use today.

Toward the end of the CRT era, manufacturers began directly competing with the plasma and liquid-crystal displays that were threatening to overtake the market. The mid-2000s saw a brief enthusiasm for “ultra-slim” models, which touted tubes as miraculously thin as 15 inches. Some manufacturers adopted new high-definition HDMI connections. These machines maintained a tenuous advantage at first: new flat-panel TVs cost thousands of dollars, and consumers had to sort through a confusing assortment of unproven display technologies. But as these screens got cheaper, bigger, and had higher-resolutions, there was no way for the CRT to win. Its design relied on a fat glass tube, which became deeper and heavier with every added inch of screen space. Sony’s hulking 40-inch Trinitron from 2002, one of the biggest consumer CRTs ever produced, weighed over 300 pounds. A modern 40-inch Sony TV, the second-smallest option in its current lineup, weighs less than 20 pounds.

But flatscreens haven’t won everyone over. Ian Primus, an IT repair technician and CRT aficionado, has amassed a basement and storage unit full of old TVs. He has a reputation as one of the increasingly few people who will take CRTs off people’s hands. “If you let people know that you’re looking for old TVs, suddenly you’ve got three or four people calling you,” he says. He gives out his number to thrift stores that have decided the bulky sets are more trouble than they’re worth and want to direct donors elsewhere. Sometimes he simply drives around at night before garbage collection, looking for castoffs.

A video game’s look and feel is often highly dependent on specific hardware setups, and for most of the medium’s history, those setups often involved a CRT. The iconic black scanlines we associate with old games, for instance, exist because consoles would tell a TV to only draw every other line — thus avoiding the flickering that interlaced video could produce, and smoothing out the overall image. (For more detail, retro gaming enthusiast Tobias Reich maintains an exhaustive guide about scanlines and other CRT rendering issues.) Old games may look torn or feel laggy on a new TV. That’s in part because LCD screens process an entire frame of an image and then display it, rather than receiving a signal and drawing it right away.

Some games are completely dependent on the display technology. One of the best-known examples is Duck Hunt, which uses Nintendo’s Zapper light gun. When players pull the trigger, the entire screen briefly flashes black, then a white square appears at the “duck’s” location. If the optical sensor detects a quick black-then-white pattern, it’s a hit. The entire Zapper system is coded for a CRT’s super fast refresh rate, and it doesn’t work on new LCD TVs without significant DIY modification.

As with many debates in the gaming world, there’s disagreement over whether new TVs are truly unusable. Not everyone believes the lag is bad enough to justify keeping an old CRT around, especially as flat-panel displays have gotten more responsive. But for now, visiting the Melee section of an e-sports tournament is a little like stepping back in time, as sleek LCD screens give way to bulky black boxes. Some of those boxes belong to Primus. He leases them out to gatherings around his hometown of Albany, as well as larger events across the region, like the Boston-based tournament Shine.

Shi Deng, co-founder of Shine’s organizing body Big Blue Esports, estimates the tournament used about 100 CRTs last year. Some events let players bring their own displays, but Shine doesn’t; they’re a pain to set up, and there’s too much liability if someone drops a 50- or 100-pound television on the ground. (An abandoned CRT caused real panic at one Detroit tournament last year, when police shut down the surrounding block out of fear it might be a bomb.) Instead, they rent from a handful of providers, who might truck the screens in from hundreds of miles away, coordinating tournament dates so there are enough TVs to go around.

The CRT’s slow extinction is also becoming a pressing problem for arcades, especially with the rise of arcade bars over the past decade. Establishments like San Francisco’s Brewcade, Portland’s Ground Kontrol, and Chicago’s Emporium Arcade Bar all line their walls with dozens of nostalgia-inspiring cabinets and by extension, dozens of CRT displays.

Barcade, one of the largest — and most strictly retro-focused — chains, has about 350 games spread across seven locations. It has almost an equal number in storage. The company carefully preserves original, untouched cabinets for games like Centipedeand Tetris. But it also buys a lot of sloppy “conversions” — machines that arcade operators hacked to install new games, with different paint jobs and controls. It strips these down for parts, operating out of what Barcade co-founder and CEO Paul Kermizian jokingly refers to as a “secret lair” on the outskirts of New York City. They give the cabinets to collectors for restoration, swap individual components into vintage machines, and hold onto the tubes until they can’t possibly be fixed.

These places may eventually have to start installing LCD monitors in cabinets, and the results might not be disastrous. Software filters can approximate a CRT’s trademark image distortions, like scanlines or the curve of a screen, and a tinted glass panel can enhance the illusion. Not all arcades are so dependent on CRTs, either. Classic arcade series like Street Fighter switched to LCD-based cabinets years ago. A wave of indie game developers have designed a host of cabinet-based games with modern displays, ranging from weird, arty experiments to traditional-looking two-player boxes.

Barcade, for one, will hold onto CRTs as long as possible — and Kermizian thinks that will be a while. “I think there’s plenty around for at least 10 years, before anyone even stresses about it,” he says. It’s still cheaper to buy old parts than to retrofit a cabinet for LCD, a process Kermizian says would cost about $350. And paradoxically, he says fear of an impending shortage could free up more tubes, as some competitors preemptively adopt LCD displays to get ahead of the curve.

“The day maybe will come when we have to do an emulation of a CRT. We’ll be pretty sad,” he says. “But there are a lot of tubes out there. It’s not dire at this point. Not for us, anyway.”

It’s one thing to round up screens for a video game tournament, or even swap out the tube in an arcade cabinet. But what if an artist has turned a mass-market television set into something truly one-of-a-kind and that television set is about to wear out? This is the question that Chi-Tien Lui has built his life around, and one that few people are so well equipped to answer.

Today, Lui specializes in maintaining pieces like Paik’s Untitled (Piano), a player piano piled high with televisions displaying closed-circuit footage of its interior workings. He’s been fixing TVs for so long that he knows exactly which brands have compatible parts, across decades’ worth of hardware, including the now-rare Korean monitors that Paik favored. That’s particularly important for the museums that hire him to help replicate the precise original look of video art installations. It’s a task that’s much easier if you can just replace a broken tube with one of the right shape and size, rather than replacing the entire set. When he eventually retires, the prospect of losing that expertise makes the future of CTL Electronics — which employs Lui’s daughter and a handful of other employees — uncertain.

CRTs are tough pieces of hardware, but as they age, plenty of things can go wrong. The electron gun can weaken, giving screens a dim, yellowish tinge. An electrical transformer can blow out. The phosphor can burn away unevenly, leaving permanent, ghostly outlines of images behind.

Lui works with a German engineer who helps refurbish tubes — by installing a new electron gun to fix yellowing, for example. Much of his work involves sifting through the vast but shrinking pool of CRT detritus. He scours eBay for old TVs and parts, snapping them up in bulk, and hopes that most of them will work when they arrive. “It’s getting harder and harder, and the price goes up and up and up,” he says. He gestures toward a sizable Sony Trinitron, one of his prize finds. “Ten years ago, I could get them under $100. Now it’s $2,000. Certain TVs, everybody wanted to grab.”

Getting rid of the broken or unwanted CRTs, though, is a nightmare. “CRTs are essentially the bane of the electronic recycling industry,” says Andrew Orben, director of business development at Tekovery, one of the companies Barcade uses to dispose of irrevocably broken hardware. The tubes contain toxic metals that could leach into a dump site, and 18 states specifically ban sending them to landfills. They’re made of raw materials that are often impossible to sell at a profit, primarily glass that’s mixed with several pounds of lead. When CRTs were still being made, that was a useful resource, but recyclers have struggled to find other uses. Companies could once export the tubes abroad, but as LCDs become more commonplace, CRTs are becoming less and less attractive.

Tekovery doesn’t dismantle the CRTs it receives, and Orben says few e-waste companies in America will handle that part of the operation. Over the past few years, several supposed CRT “recyclers” have been caught secretly abandoning their old displays in vast television graveyards. Iowa’s attorney general sued the now-defunct company Recycletronics in January for storing 4.6 million pounds of leaded CRT glass, along with other e-waste, across eight facilities in two states. A lawsuit last year targeted a former partner of Recycletronics, which kept a staggering 113 million pounds of glass in two Ohio warehouses.

“There are companies in the industry that are specifically looking for long-term solutions” to the CRT recycling question, says Orben. But they’ve faced their own difficulties. Nulife, a company that legitimately smelted down old tubes for commercial sale, was ordered to scrap its backlog of glass after failing regulatory checks. It pulled out of the US market last year.

In the meantime, he has no intention of moving into the world of repairing flatscreens. “When the iPod, iPad came out, I quit learning new things,” he says. The new generation of electronics, he says, is fundamentally different from the old one. You could go to a factory training program and learn how to repair a CRT. “The new TVs, they don’t want you to repair.”

A cathode ray tube (CRT) is the glass video display component of an electronic device (usually a television or computer monitor). EPA encourages repair and reuse as a responsible ways to manage CRTs. If reuse or repair are not practical options, CRTs can be recycled. Recycled CRTs are typically disassembled so that valuable materials can be recovered.

Cathode ray tube (CRT) display uses CRT that is a vacuum tube medium interpreting electrical phenomenon of an image projected on a phosphorescent screen by sharp focused beam of electrons being controlled by an intensity of electrical signals. It consists of one or more electron guns and a phosphorescent screen to display images or signals. CRT displays are used in the residential sector as they can operate at any resolution, geometry, and aspect ratio without the need to rescale an image.

CRT displays are mostly preferred in PC gaming circles as they offer high pixel resolution, respond to input faster, have less motion blur than LCDs, and are suitable for use in both dimly lit and dark environments. CRT displays are less expensive and produce perfectly smooth gray scale with an infinite number of intensity levels, which enhances product quality standards in the market. Significant advantages of this display technology over smart LCD
