Video Graphics Array Extended Video Graphics Array (or EVGA ) is a standard created by VESA in 1991 ( VBE 1.2) [ 1 ] [ 2 ] [ 3 ] denoting a non-interlaced resolution of 1024x768 at a maximum of 70 Hz refresh rate .
Alternative to RCA for professional video electronics. Protocols: Serial digital interface (SDI) and HD-SDI. CoaXPress; 75 Ω for video signal (SDI and CoaXPress) on, for example, RG59 and RG6. 50 Ω for data link, like Ethernet on RG58. 93 Ω on RG62. 50 Ω (white/bottom row) and 75 Ω C connectors (red/top row) C connector (Concelman connector)
An enlargement of a small section of a 1024x768 (VESA XGA) resolution image; the individual pixels are more visible in its scaled form than its normal resolution.A video scaler is a system that converts video signals from one display resolution to another; typically, scalers are used to convert a signal from a lower resolution (such as 480p standard definition) to a higher resolution (such as ...
FHD (Full HD) is the resolution 1920 × 1080 used by the 1080p and 1080i HDTV video formats. It has a 16:9 aspect ratio and 2,073,600 total pixels, i.e. very close to 2 megapixels, and is exactly 50% larger than 720p HD ( 1280 × 720 ) in each dimension for a total of 2.25 times as many pixels.

Ultra High-Definition, or Quad Full High-Definition Four times the resolution of 1080p. Requires a dual-link DVI, category 2 (high-speed) HDMI, DisplayPort or a single Thunderbolt link, and a reduced scan rate (up to 30 Hz); a DisplayPort 1.2 connection can support this resolution at 60 Hz, or 30 Hz in stereoscopic 3D. 3840×2160 (8,294k) 3840
VGA section on the motherboard in IBM PS/55. The color palette random access memory (RAM) and its corresponding digital-to-analog converter (DAC) were integrated into one chip (the RAMDAC) and the cathode-ray tube controller was integrated into a main VGA chip, which eliminated several other chips in previous graphics adapters, so VGA only additionally required external video RAM and timing ...
The older Academy format of Anamorphic widescreen was a response to a shortcoming in the non-anamorphic spherical (a.k.a. "flat") widescreen format. With a non-anamorphic lens, the picture is recorded onto the film negative such that its full width fits within the film's frame, but not its full height.
