A VGA to TV scan converter box like this turns enhanced-definition or high-definition signals into standard-definition signals. Up conversion ( interpolation ): In many LCD monitors there is a native picture mode, however the monitor can display different graphical modes using a scan converter.
Coordinated Video Timings (CVT; VESA-2013-3 v1.2 [1]) is a standard by VESA which defines the timings of the component video signal.Initially intended for use by computer monitors and video cards, the standard made its way into consumer televisions.
A Brooktree RAMDAC. A RAMDAC (random-access memory digital-to-analog converter) is a combination of three fast digital-to-analog converters (DACs) with a small static random-access memory (SRAM) used in computer graphics display controllers or video cards to store the color palette and to generate the analog signals (usually a voltage amplitude) to drive a color monitor.

In the Linux systems, a patch named vga_switcheroo [13] has been added to the Linux kernel since version 2.6.34 in order to deal with multiple GPUs. Here, the switch requires a restart of the X Window System to be taken into account. Ubuntu Control Center allows the user to access vga_switcheroo functionality through a GUI.
For example, a VGA-signal, which is created by GPU is being transported over a VGA-cable to the monitor built-in controller. Both ends of the cable end in a VGA connector. Laptops and other mobile computers use different interfaces between the display controller and the display. A display controller usually supports multiple computer display ...
An extension to VGA defined by VESA for IBM PC-compatible computers in 1989 meant to take advantage of video cards that exceeded the minimum 256 kB defined in the VGA standard. For instance, one of the early supported modes was 800×600 in 16 colours at a slightly lower 56 Hz refresh rate, leading to 800×600 sometimes being referred to as ...
Default VGA 256-color palette. Mode 13h is the standard 256-color mode on VGA graphics hardware introduced in 1987 with the IBM PS/2. It has a resolution of 320 × 200 pixels. [1] It was used in computer games and art/animation software of the late 1980s and early to mid-1990s. [citation needed] "13h" refers to the number of the mode in the VGA ...
BIOS Modes 2 and 3 select 80 columns by 25 rows text modes, with each character still an 8×8 dot pattern, but displayed at a higher scan rate. The effective screen resolution of this mode is 640 × 200 pixels. In this mode, the card has enough video RAM for four different text pages.
