Video random-access memory (VRAM) is dedicated computer memory used to store the pixels and other graphics data as a framebuffer to be rendered on a computer monitor. [1] It often uses a different technology than other computer memory, in order to be read quickly for display on a screen.
Memory: 64 KB RAM, 16 KB video RAM; 32 KB ROM Expansion: 3 internal slots, 1 cartridge slot, and a 62.5 kbit/s half-duplex serial bus called AdamNet. Both the stand-alone and expansion-module versions also have an external expansion port of the same type as the ColecoVision expansion port, on the right hand side.
The single fixed-screen mode used in first-generation (128k and 512k) Apple Mac computers, launched in 1984, with a monochrome 9" CRT integrated into the body of the computer. Used to display one of the first mass-market full-time GUIs, and one of the earliest non-interlaced default displays with more than 256 lines of vertical resolution.
Each sprite is either 8×8 or 16×16 pixels and can be scaled 2× to 16×16 or 32×32. 16 KB of RAM is provided for the Video Display Processor. VDP RAM is the largest block of writeable memory in the unexpanded TI-99/4A architecture, and is used for storing disk I/O buffers and TI BASIC user programs.
The controller can then continue to use the DRAM port for drawing objects on the display. Meanwhile, the controller feeds a clock called the shift clock (SCLK) to the VRAM's video port. Each SCLK pulse causes the VRAM to deliver the next data [computing] in strict address order, from the shift register to the video port. For simplicity, the ...
Example video in 16K (16000 × 9000 pixels) A VR video in 16K (16000 × 8000 pixels) 16K resolution is a display resolution with approximately 16,000 pixels horizontally. The most commonly discussed 16K resolution is 15360 × 8640, which doubles the pixel count of 8K UHD in each dimension, for a total of four times as many pixels. [1]
The original IBM CGA graphics card was built around the Motorola 6845 display controller, [2] came with 16 kilobytes of video memory built in, and featured several graphics and text modes. The highest display resolution of any mode was 640 × 200, and the highest color depth supported was 4-bit (16 colors).
The Compaq Contura Aero 4/25 and 4/33c were among the earliest subnotebook computers that acted as a precursor to netbooks. They were released in 1994 and originally ran MS-DOS and Windows 3.1. They were also able to run Windows 95 after its release in 1995. They were similar to the Armada line of laptop computers, but smaller. Although the 4/ ...
