Refresh – (vertical scan rate) the time it takes to fill the screen from top to bottom, standard rate 70MHZ

Interlaced – two passes to draw a screen even lines/odd lines, slow rate and have a slight flicker

Non-interlaced – one pass to draw screen low flicker

Dot Pitch – distance between dots (red,green,blue) smaller in size better picture .28mm/.25mm the best.
.35mm/.38mm low res.

Resolution – the number of spots that is actually accessed by the software.

Pixel – is the area that produces the image low-high res, standard is 800 x 600 and high 1024 x 7

Multiscan Monitor – provide many varieties of vertical and horizontal refresh rates, expensive.

Green Monitor – meets EPA Energy Star program & use 100 to 150 watts of electricity.
When saver is on uses only 30 watts.

Vesa – video electronics standards association

Video RAM – data stored in memory of the video card

DRAM – dynamic random access memory - standard

VRAM – video random access memory – faster

MDRAM – multi dynamic access memory – uses a full 128 bit path

SGRAM- synchronous graphics random access memory, designed for video card processing, improves
performance by interacting with CPU bus clock

WRAM – Window random access memory – less expensive

3D-Ram – memory is embedded in microprocessor and improves performance

640 x 480 res – number of pixels that make up the image for a standard monitor

800 X 600 res – number of pixels for standard software applications

1024 x 768 res – number of pixels that make up the image for high performance monitor

CRT – cathode ray tube

MGA – monochrome graphics adapter

CGA – color graphics adapter

VGA – video graphics array

SVGA – super video graphics array

LCD – liquid crystal display
