3D Glasses:

3D glasses, also called anaglyph glasses, are a type of glasses that can be used to give an otherwise two dimensional image, text or film three dimensional depth. 3D glasses are used mainly for entertainment, movies in particular, and to a lesser degree in science. The glasses themselves have two differently coloured lenses, one in red and one in blue.

Passive 3D Glasses / Polarized 3D Glasses

Modern monitors are capable of 3D images by using a polarized screen. The glasses are slightly grey and does dim the image. This is because of the technology used. No batteries or power is required.

Active 3D glasses

Active 3D glasses works by switching each lens on and off rapidly in sync with the relevant image on screen. Batteries are required.

Gaming monitors - what is a gaming monitor?

Gaming monitors have various technologies that appeal to gamers such as faster refresh rates of 100Hz / 120Hz / 144Hz / 160Hz / 165Hz / 180Hz / 200Hz / 240Hz  or more and a gray-to-gray response of 2 milliseconds or less.

G-Sync and FreeSync The latest crop of gaming monitors use synchronization technology to help reduce tearing and other motion artifacts while lowering input lag. Monitors equipped with Nvidia's G-Sync or AMD's FreeSync modules give control of the screen's refresh rate to the GPU instead of the monitor, which allows the display to operate with a variable refresh rate.

Standard Refresh rates

50Hz   / 60Hz  is the standard refresh rates for monitors.

High end monitors and gaming monitor have refresh rates are 100Hz / 120Hz / 144Hz or 240Hz.

For a long time 144Hz was the de facto standard gaming monitor refresh rate (6 x 24Hz) .

Why 24Hz?

Hollywood movies and cinemas run at just 24Hz! This is a standard that was chosen decades ago.

When viewing movies at 144Hz, i still looks good - to our brain.

Some viewers have difficulty viewing movies at 120Hz or 240Hz since frames have to drop or duplicate to compensate for the difference in frame rates, creating micro-stutters that our brains pick up, and makes viewing at these rates irritating for a small percentage of viewers.

Games are perfectly synced to whatever frame rate you set, and this is not a problem.

Non-standard refresh rates (over-clocked refresh rates)

Some gaming monitors have over-clocking options.

Some gaming monitors can be over-clocked to refresh rates of 160Hz and 165Hz.
Several Standard monitors can also be over-clocked to 70Hz.

Refresh rates and gaming

The faster the refresh rate, the more times an image can update every second and the smoother the image movement will look. This is the advantage that a gamer with android-like speeds, and a keen eye for detail, needs to be the best.

Refresh rates and eye strain

For an average user who suffers eye strain when looking at a monitor, a 120Hz monitor is optimal in relieving eye strain doing PC work, and 144Hz when viewing movies.

CRT Monitors:

A CRT is the the old, square and heavy "box-type" monitor.

These monitors are difficult to find. The CRT no longer cuts it in modern gaming, or for viewing digital TV.

These monitors can still be found with CCTV systems and on some testing devices.

LCD Monitors:

Thin film transistor liquid crystal display (TFT-LCD) is a variant of liquid crystal display (LCD) which uses thin-film transistor (TFT) technology to improve image quality (e.g., addressability, contrast). TFT LCD is one type of Active matrix LCD, though all LCD-screens are based on TFT active matrix addressing. TFT LCD s are used in television sets, computer monitors, mobile phones, hand held video game systems, personal digital assistants, navigation systems, projectors, etc

LED Monitors:

A light-emitting diode (LED) is a semiconductor light source. LEDs are used as indicator lamps in many devices and are increasingly used for other lighting. Introduced as a practical electronic component in 1962, early LEDs emitted low-intensity red light, but modern versions are available across the visible, ultraviolet, and infra-red wavelengths, with very high brightness. When a light-emitting diode is forward-biased (switched on), electrons are able to recombine with electron holes within the device, releasing energy in the form of photons. This effect is called electro luminescence and the colour of the light (corresponding to the energy of the photon) is determined by the energy gap of the semiconductor. LEDs are often small in area (less than 1 mm2), and integrated optical components may be used to shape its radiation pattern. LEDs present many advantages over incandescent light sources including lower energy consumption, longer lifetime, improved robustness, smaller size, and faster switching. LEDs powerful enough for room lighting are relatively expensive and require more precise current and heat management than compact fluorescent lamp sources of comparable output. Light-emitting diodes are used in applications as diverse as replacements for aviation lighting, automotive lighting (in particular brake lamps, turn signals, and indicators) as well as in traffic signals. LEDs have allowed new text, video displays, and sensors to be developed, while their high switching rates are also useful in advanced communications technology. Infra-red LEDs are also used in the remote control units of many commercial products including televisions, DVD players, and other domestic appliances.

An LED display is a flat panel display, which uses light-emitting diodes as a video display. An LED panel is a small display, or a component of a larger display. They are typically used outdoors in store signs and billboards, and in recent years have also become commonly used in destination signs on public transport vehicles or even as part of transparent glass area. LED panels are sometimes used as form of lighting, for the purpose of general illumination, task lighting, or even stage lighting rather than display.
