The PS/2 chipset's limited abilities prevent EGA compatibility and high-resolution multi-color VGA display modes. The tenure of MCGA was brief; the PS/2 Model 25 and Model 30 were discontinued by 1992, and the only manufacturer to produce a clone of this display adapter was Epson , in the Equity Ie and PSE-30 , since the VGA standard introduced ...
The Linux kernel allows the user to select the VESA mode at boot time by passing a code in memory to the kernel. The LILO boot loader passes this code based on a "vga" parameter in its configuration file. It takes the form 'vga=XXX', where XXX is the decimal value, or 'vga=0xHHH', where HHH is the hexadecimal value.
It is in the process of being replaced with an AMDGPU-PRO hybrid driver combining the open-source kernel, X and Mesa multimedia drivers with closed-source OpenGL, OpenCL and Vulkan drivers derived from Catalyst. The FOSS drivers for ATI-AMD GPUs are being developed under the name Radeon (xf86-video-ati or xserver-xorg-video-radeon). They still ...
A VGA extender is an electronic device that increases the signal strength from a VGA port, most often from a computer. They are often used in schools, businesses, and homes when multiple monitors are being run off one VGA port, or if the cable between the monitor and the computer will be excessively long (often pictures appear blurry or have ...
For a read command, the PHY takes over the MDIO line during the turnaround bit times, supplies the MAC with the register data requested, then releases the MDIO line. When the MAC drives the MDIO line, it has to guarantee a stable value 10 ns (setup time) before the rising edge of the clock MDC.
Display Data Channel (DDC) is a collection of protocols for digital communication between a computer display and a graphics adapter that enable the display to communicate its supported display modes to the adapter and that enable the computer host to adjust monitor parameters, such as brightness and contrast.
It was possible for the programmer to embed the graphic driver into the executable file by linking the graphic driver as object code with the aid of a utility provided by the compiler (bgiobj.exe). There were graphic drivers for common graphic adapters and printers of that time, such as CGA, EGA, VGA, Hercules, AT&T 400, MCGA and 3270 PC .
The Mini-DVI connector is used on certain Apple computers as a digital alternative to the Mini-VGA connector. Its size is between the full-sized DVI and the tiny Micro-DVI.It is found on the 12-inch PowerBook G4 (except the original 12-inch 867 MHz PowerBook G4, which used Mini-VGA), the Intel-based iMac, the MacBook Intel-based laptop, the Intel-based Xserve, and the 2009 Mac mini.
