Video calibration software is software used to improve the quality of commercial video reproduction.. Organizations such as the Society for Motion Picture and Television Engineers (SMPTE), the Commission Internationale de l'Eclairage, the Advanced Television Systems Committee (ATSC), and the International Telecommunication Union (ITU) have established standards for the proper transmission and ...
requires skilled convergence calibration and adjustments for geographic location changes. [46] Glass display tube is evacuated and carries risk of implosion if improperly handled. May be risky and expensive to repair due to complexity of the display; [ 47 ] units with mercury CCFL backlight lamps are an environmental health hazard [ 48 ]
Logo The Christie Mirage 5000, a 2001 DLP projector. Digital light processing (DLP) is a set of chipsets based on optical micro-electro-mechanical technology that uses a digital micromirror device. It was originally developed in 1987 by Larry Hornbeck of Texas Instruments. While the DLP imaging device was invented by Texas Instruments, the ...
A thinner and lighter LCD or DLP projection TV in a home cinema. A projection television uses a projector to create a small image or video from a video signal and magnify this image onto a viewable screen. The projector uses a bright beam of light and a lens system to project the image to a much larger size.

A DMD chip, used in most projectors and some TVs. The digital micromirror device, or DMD, is the microoptoelectromechanical system (MOEMS) that is the core of the trademarked Digital Light Processing (DLP) projection technology from Texas Instruments (TI).
Rendition of SD ECR-1-1978 color bars Colors are only approximate due to different transfers and color spaces used on web pages and video (BT.601 or BT.709). SMPTE color bars are a television test pattern used where the NTSC video standard is utilized, including countries in North America.
A good monitor with proper calibration shows the six numbers on the right in both bars, a cheap monitor shows only four numbers. Given a desired display-system gamma, if the observer sees the same brightness in the checkered part and in the homogeneous part of every colored area, then the gamma correction is approximately correct.
