Yes, it happens. It was 2013 when I had a phone call from BenQ, a multinational manufacturer of LCD monitors. The project manager mentioned that one kind of LCD TV screen they were currently shipping damage. BenQ team looked for a solution from us to prevent broken TV monitors when shipped because defective products are not what any good business would want to do.

It was BenQ’s biggest embarrassment. They had a factory in mainland China and every time certain models of LCD screens were produced, they would be shipped to PChome Taiwan for sale. However, the recent damage rate of the goods had been abnormally high up to nearly 20%. Taking preventive measures, such as adjustment of packaging materials or structure, etc., there is no significant effect.

The situation became increasingly serious and it’s not just that it was BenQ who noticed this problem; customers’ feedback also showed that their LCD TVs were suffering from abnormal damages when delivered to them. Without any big accidents happening during the transportation or delivery process at all – one could only imagine what was going on inside those.

We had conducted a study on what type of shock can affect the LCD screen and how much damage it entails. We first put types of indicators labels in the box of the LCD panel in order to determine how much force damage would occur during regular shipment and transit.

In confirmation of the true cause, BenQ officially imported Impact Labels to adhere to each TV box, as well as to inform all handlers of the impact indicator monitor is in place.

A study shows the damage rate typically drops by 50% or more when a monitor is in place. The TV screens are rarely damaged in this case, which proves the statement.

In fact, change the handling environment is the fastest and most effective way to solve damaged LCD TV screens, and where Impact Label comes to play! BenQ is not the first user of impact indicators in LCD TV manufacturers. To comply with your LCD TV, our free consultant and free samples for testing are waiting for you.

Current state and federal regulations mandate that cathode ray tubes (CRTs) found in computer monitors and televisions cannot be disposed of in landfills. However, there are several REUSE & RECYCLING options available to Kern County residents:

• Non-working computer monitors and televisions are accepted at Kern County Disposal sites and Special Waste Facilities (see page 14) for recycling at NO CHARGE.

• Non-working computer monitors and televisions are also accepted for recycling at thrift shops and non-profit organizations such as Goodwill Industries, Salvation Army, St. Vincent de Paul, Bakersfield Association of Retarded Citizens (BARC) and others that have been authorized by the state.

The display in modern monitors is typically an LCD with LED backlight, having by the 2010s replaced CCFL backlit LCDs. Before the mid-2000s,CRT. Monitors are connected to the computer via DisplayPort, HDMI, USB-C, DVI, VGA, or other proprietary connectors and signals.

Originally, computer monitors were used for data processing while television sets were used for video. From the 1980s onward, computers (and their monitors) have been used for both data processing and video, while televisions have implemented some computer functionality. In the 2000s, the typical display aspect ratio of both televisions and computer monitors has changed from 4:3 to 16:9.

Modern computer monitors are mostly interchangeable with television sets and vice versa. As most computer monitors do not include integrated speakers, TV tuners, nor remote controls, external components such as a DTA box may be needed to use a computer monitor as a TV set.

Early electronic computer front panels were fitted with an array of light bulbs where the state of each particular bulb would indicate the on/off state of a particular register bit inside the computer. This allowed the engineers operating the computer to monitor the internal state of the machine, so this panel of lights came to be known as the "monitor". As early monitors were only capable of displaying a very limited amount of information and were very transient, they were rarely considered for program output. Instead, a line printer was the primary output device, while the monitor was limited to keeping track of the program"s operation.

Multiple technologies have been used for computer monitors. Until the 21st century most used cathode-ray tubes but they have largely been superseded by LCD monitors.

The first computer monitors used cathode-ray tubes (CRTs). Prior to the advent of home computers in the late 1970s, it was common for a video display terminal (VDT) using a CRT to be physically integrated with a keyboard and other components of the workstation in a single large chassis, typically limiting them to emulation of a paper teletypewriter, thus the early epithet of "glass TTY". The display was monochromatic and far less sharp and detailed than on a modern monitor, necessitating the use of relatively large text and severely limiting the amount of information that could be displayed at one time. High-resolution CRT displays were developed for specialized military, industrial and scientific applications but they were far too costly for general use; wider commercial use became possible after the release of a slow, but affordable Tektronix 4010 terminal in 1972.

Some of the earliest home computers (such as the TRS-80 and Commodore PET) were limited to monochrome CRT displays, but color display capability was already a possible feature for a few MOS 6500 series-based machines (such as introduced in 1977 Apple II computer or Atari 2600 console), and the color output was a speciality of the more graphically sophisticated Atari 800 computer, introduced in 1979. Either computer could be connected to the antenna terminals of an ordinary color TV set or used with a purpose-made CRT color monitor for optimum resolution and color quality. Lagging several years behind, in 1981 IBM introduced the Color Graphics Adapter, which could display four colors with a resolution of 320 × 200 pixels, or it could produce 640 × 200 pixels with two colors. In 1984 IBM introduced the Enhanced Graphics Adapter which was capable of producing 16 colors and had a resolution of 640 × 350.

By the end of the 1980s color progressive scan CRT monitors were widely available and increasingly affordable, while the sharpest prosumer monitors could clearly display high-definition video, against the backdrop of efforts at HDTV standardization from the 1970s to the 1980s failing continuously, leaving consumer SDTVs to stagnate increasingly far behind the capabilities of computer CRT monitors well into the 2000s. During the following decade, maximum display resolutions gradually increased and prices continued to fall as CRT technology remained dominant in the PC monitor market into the new millennium, partly because it remained cheaper to produce.

There are multiple technologies that have been used to implement liquid-crystal displays (LCD). Throughout the 1990s, the primary use of LCD technology as computer monitors was in laptops where the lower power consumption, lighter weight, and smaller physical size of LCDs justified the higher price versus a CRT. Commonly, the same laptop would be offered with an assortment of display options at increasing price points: (active or passive) monochrome, passive color, or active matrix color (TFT). As volume and manufacturing capability have improved, the monochrome and passive color technologies were dropped from most product lines.

The first standalone LCDs appeared in the mid-1990s selling for high prices. As prices declined they became more popular, and by 1997 were competing with CRT monitors. Among the first desktop LCD computer monitors was the Eizo FlexScan L66 in the mid-1990s, the SGI 1600SW, Apple Studio Display and the ViewSonic VP140vision science remain dependent on CRTs, the best LCD monitors having achieved moderate temporal accuracy, and so can be used only if their poor spatial accuracy is unimportant.

High dynamic range (HDR)television series, motion pictures and video games transitioning to widescreen, which makes squarer monitors unsuited to display them correctly.

Organic light-emitting diode (OLED) monitors provide most of the benefits of both LCD and CRT monitors with few of their drawbacks, though much like plasma panels or very early CRTs they suffer from burn-in, and remain very expensive.

Radius of curvature (for curved monitors) - is the radius that a circle would have if it had the same curvature as the display. This value is typically given in millimeters, but expressed with the letter "R" instead of a unit (for example, a display with "3800R curvature" has a 3800mm radius of curvature.

Dot pitch represents the distance between the primary elements of the display, typically averaged across it in nonuniform displays. A related unit is pixel pitch, In LCDs, pixel pitch is the distance between the center of two adjacent pixels. In CRTs, pixel pitch is defined as the distance between subpixels of the same color. Dot pitch is the reciprocal of pixel density.

Pixel density is a measure of how densely packed the pixels on a display are. In LCDs, pixel density is the number of pixels in one linear unit along the display, typically measured in pixels per inch (px/in or ppi).

Contrast ratio is the ratio of the luminosity of the brightest color (white) to that of the darkest color (black) that the monitor is capable of producing simultaneously. For example, a ratio of 20,000∶1 means that the brightest shade (white) is 20,000 times brighter than its darkest shade (black). Dynamic contrast ratio is measured with the LCD backlight turned off. ANSI contrast is with both black and white simultaneously adjacent onscreen.

Color depth - measured in bits per primary color or bits for all colors. Those with 10bpc (bits per channel) or more can display more shades of color (approximately 1 billion shades) than traditional 8bpc monitors (approximately 16.8 million shades or colors), and can do so more precisely without having to resort to dithering.

Refresh rate is (in CRTs) the number of times in a second that the display is illuminated (the number of times a second a raster scan is completed). In LCDs it is the number of times the image can be changed per second, expressed in hertz (Hz). Determines the maximum number of frames per second (FPS) a monitor is capable of showing. Maximum refresh rate is limited by response time.

On two-dimensional display devices such as computer monitors the display size or view able image size is the actual amount of screen space that is available to display a picture, video or working space, without obstruction from the bezel or other aspects of the unit"s design. The main measurements for display devices are: width, height, total area and the diagonal.

With the introduction of flat panel technology, the diagonal measurement became the actual diagonal of the visible display. This meant that an eighteen-inch LCD had a larger viewable area than an eighteen-inch cathode-ray tube.

Until about 2003, most computer monitors had a 4:3 aspect ratio and some had 5:4. Between 2003 and 2006, monitors with 16:9 and mostly 16:10 (8:5) aspect ratios became commonly available, first in laptops and later also in standalone monitors. Reasons for this transition included productive uses for such monitors, i.e. besides Field of view in video games and movie viewing, are the word processor display of two standard letter pages side by side, as well as CAD displays of large-size drawings and application menus at the same time.LCD monitors and the same year 16:10 was the mainstream standard for laptops and notebook computers.

In 2011, non-widescreen displays with 4:3 aspect ratios were only being manufactured in small quantities. According to Samsung, this was because the "Demand for the old "Square monitors" has decreased rapidly over the last couple of years," and "I predict that by the end of 2011, production on all 4:3 or similar panels will be halted due to a lack of demand."

The resolution for computer monitors has increased over time. From 280 × 192 during the late 1970s, to 1024 × 768 during the late 1990s. Since 2009, the most commonly sold resolution for computer monitors is 1920 × 1080, shared with the 1080p of HDTV.2560 × 1600 at 30 in (76 cm), excluding niche professional monitors. By 2015 most major display manufacturers had released 3840 × 2160 (4K UHD) displays, and the first 7680 × 4320 (8K) monitors had begun shipping.

Most modern monitors will switch to a power-saving mode if no video-input signal is received. This allows modern operating systems to turn off a monitor after a specified period of inactivity. This also extends the monitor"s service life. Some monitors will also switch themselves off after a time period on standby.

Most modern monitors have two different indicator light colors wherein if video-input signal was detected, the indicator light is green and when the monitor is in power-saving mode, the screen is black and the indicator light is orange. Some monitors have different indicator light colors and some monitors have blinking indicator light when in power-saving mode.

Many monitors have other accessories (or connections for them) integrated. This places standard ports within easy reach and eliminates the need for another separate hub, camera, microphone, or set of speakers. These monitors have advanced microprocessors which contain codec information, Windows interface drivers and other small software which help in proper functioning of these functions.

Monitors that feature an aspect ratio greater than 2:1 (for instance, 21:9 or 32:9, as opposed to the more common 16:9, which resolves to 1.77:1).Monitors with an aspect ratio greater than 3:1 are marketed as super ultrawide monitors. These are typically massive curved screens intended to replace a multi-monitor deployment.

These monitors use touching of the screen as an input method. Items can be selected or moved with a finger, and finger gestures may be used to convey commands. The screen will need frequent cleaning due to image degradation from fingerprints.

Some displays, especially newer flat panel monitors, replace the traditional anti-glare matte finish with a glossy one. This increases color saturation and sharpness but reflections from lights and windows are more visible. Anti-reflective coatings are sometimes applied to help reduce reflections, although this only partly mitigates the problem.

Most often using nominally flat-panel display technology such as LCD or OLED, a concave rather than convex curve is imparted, reducing geometric distortion, especially in extremely large and wide seamless desktop monitors intended for close viewing range.

Newer monitors are able to display a different image for each eye, often with the help of special glasses and polarizers, giving the perception of depth. An autostereoscopic screen can generate 3D images without headgear.

Raw monitors are raw framed LCD monitors, to install a monitor on a not so common place, ie, on the car door or you need it in the trunk. It is usually paired with a power adapter to have a versatile monitor for home or commercial use.

A stowable rack mount monitor is 1U, 2U or 3U high and is mounted on rack slides allowing the display to be folded down and the unit slid into the rack for storage as a drawer. The flat display is visible only when pulled out of the rack and deployed. These units may include only a display or may be equipped with a keyboard creating a KVM (Keyboard Video Monitor). Most common are systems with a single LCD but there are systems providing two or three displays in a single rack mount system.

An open frame monitor provides the display and enough supporting structure to hold associated electronics and to minimally support the display. Provision will be made for attaching the unit to some external structure for support and protection. Open frame monitors are intended to be built into some other piece of equipment providing its own case. An arcade video game would be a good example with the display mounted inside the cabinet. There is usually an open frame display inside all end-use displays with the end-use display simply providing an attractive protective enclosure. Some rack mount monitor manufacturers will purchase desktop displays, take them apart, and discard the outer plastic parts, keeping the inner open-frame display for inclusion into their product.

Van Eck phreaking is the process of remotely displaying the contents of a CRT or LCD by detecting its electromagnetic emissions. It is named after Dutch computer researcher Wim van Eck, who in 1985 published the first paper on it, including proof of concept. Phreaking more generally is the process of exploiting telephone networks.

Typical LCDs are edge-lit by a strip of white LEDs. The 2D backlighting system in Pro Display XDR is unlike any other. It uses a superbright array of 576 blue LEDs that allows for unmatched light control compared with white LEDs. Twelve controllers rapidly modulate each LED so that areas of the screen can be incredibly bright while other areas are incredibly dark. All of this produces an extraordinary contrast that’s the foundation for XDR.

With a massive amount of processing power, the timing controller (TCON) chip utilizes an algorithm specifically created to analyze and reproduce images. It controls LEDs at over 10 times the refresh rate of the LCD itself, reducing latency and blooming. It’s capable of multiple refresh rates for amazingly smooth playback. Managing both the LED array and LCD pixels, the TCON precisely directs light and color to bring your work to life with stunning accuracy.

California’s Electronic Waste Recycling Act of 2003 pays us for monitor and TV recycling at no charge if they are from California. Out-of-State CRTs do not qualify for free electronics recycling. Note: We charge $.50 per pound for unqualified CRTs, monitors & TVs (CRTs) from outside of California or with inadequate or missing source information, which is the name & address of the users of the CRTs. Don’t fret! Your CRT most likely qualifies, unless you snuck it across the state border, or you went around collecting a bunch of random TVs and monitors lying around the street without getting the name and address of the owner. So, don’t go around picking-up random CRTs from the street, and we won’t have to charge you for them. Instead, we encourage you to notify the local authority about abandoned monitors and TVs so they can be properly disposed.

Non-California or “No Source Info” CRT Monitors/TVs from out-of-state or with missing or inadequate source info (name and address of the user). $ .50/lb to recycle. Although it costs us a little more, our electronics are NOT exported for treatment in countries with low environmental standards. Instead we send all our unrefurbished electronics to a Seri certified recycler in California, which processes scrap electronics by shredding and separating the components, ferrous metals (steel), copper and precious metals, aluminum, and plastic. The steel and aluminum are recycled as metals, the plastic is recycled as plastic, and the copper and precious metals are sampled, prepared, and packaged for shipment to a primary copper smelter.

The Hisense U7G offers great image quality, superb gaming features, and the Android TV interface, but it has a narrower viewing angle and comes in fewer screen sizes than some other TVs.

The Hisense U7G is a great-looking 4K TV with all the technologies and features that any LCD/LED TV should have today, including a full-array local-dimming backlight for superb black levels and image contrast as well as a 120 Hz refresh rate that delivers better motion quality than you’ll find on many competitors. It does a nice job showing high dynamic range video, thanks to its high brightness and rich color, and it supports the more advanced Dolby Vision HDR standard (which can offer improvements in image quality over the standard HDR10 format). For serious gamers, Hisense has also added all the HDMI 2.1 features necessary to take full advantage of the newest gaming consoles. (Check out TV features, defined for more explanation of the technical terms we’re using here.) The U7G features the Android TV streaming platform, which offers a wide variety of streaming services and a continually improving user interface. But the TV comes only in 55-, 65-, and 75-inch screen sizes.

If you’re willing to pay a higher price to get one of the best LCD performers we’ve tested, the Samsung QN90A is our recommendation. Moving beyond the standard LED backlight in the Hisense U7G, this TV has a mini-LED backlighting system—which offers more local-dimming zones for even better contrast ratios and brighter HDR highlights than on the Hisense—and it produces vibrant colors. It also has a wider viewing angle than our top pick, so everyone can enjoy a good-looking image no matter where they sit in the room, and it comes in more screen sizes, from 43 to 98 inches. The QN90A supports all the latest HDMI 2.1 features, which gamers will appreciate, and it uses Samsung’s proprietary Tizen streaming platform, which supports most of the popular streaming services. We like that it features a center stand so it will fit on virtually any TV furniture, and it sits high enough on the stand that you can place a soundbar in front of it without blocking the screen. The drawbacks are that the QN90A does not support the more advanced Dolby Vision high dynamic range format (but it does support the similarly advanced HDR10+ format), and it’s significantly more expensive than the Hisense U7G.

If you have a wider seating area, or if you regularly watch your TV from side angles, the Sony X950H uses an LCD panel specifically designed to produce a better-looking image at wider viewing angles than many 4K LCD TVs offer. (Our upgrade pick, the Samsung QN90A, employs a similarly effective wide-angle-viewing technology but costs more.) This TV also has Sony’s superb color accuracy and video-processing capability, so it’s better than the competition at removing banding artifacts. However, that wider viewing angle comes at the expense of the TV’s black level, which isn’t as dark as that of Hisense’s U7G or Samsung’s QN90A. Also, you don’t get the full complement of HDMI 2.1 features to improve the gaming experience. The Sony X950H is available in a variety of screen sizes, from 49 to 85 inches.
