The reason given is: vga_switcheroo is intended only for muxed systems. [12] For muxless systems, the vga_switcheroo takes care of power switching only, rendering is offloaded via DRI PRIME without the need to restart userspace programs..

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.
Each screen character is represented by two bytes aligned as a 16-bit word accessible by the CPU in a single operation. The lower (or character) byte is the actual code point for the current character set, and the higher (or attribute) byte is a bit field used to select various video attributes such as color, blinking, character set, and so forth.

It takes the form 'vga=XXX', where XXX is the decimal value, or 'vga=0xHHH', where HHH is the hexadecimal value. However, the 'vga=' boot loader parameter does not directly accept VESA video mode numbers; rather, the Linux video mode number is the VESA number plus 512 (in the case of the decimal representation) or plus 0x200 (in the case of the ...
In revision 1.2, released in 2013, a new "Reduced Blanking Timing Version 2" mode was added which further reduces the horizontal blanking interval from 160 to 80 pixels, increases pixel clock precision from ±0.25 MHz to ±0.001 MHz, and adds the option for a 1000/1001 modifier for ATSC/NTSC video-optimized timing modes (e.g. 59.94 Hz instead ...
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 ...
Windows 10 October 2018 Update (Version 1809) Includes WDDM 2.5. [52] Updates to Display driver development in Windows 10, version 1809 include the following features: [53] Shader Model 6.3, adding support for DirectX12 Raytracing (DXR). [54] Raytracing, in order to support hardware-accelerated raytracing in Direct3D 12.
The PCjr, released in 1983, has a graphics subsystem built around IBM's Video Gate Array [3] (not to be confused with the later Video Graphics Array) and an MC6845 CRTC [4] and extends on the capabilities of the Color Graphics Adapter (CGA), increasing the number of colors in each screen mode. CGA's 2-color mode can be displayed with four ...
