AGP Aperature - Species the amount of system memory that can be used by the AGP device. This aperature is a portion of the PCI memory address range dedicated for graphics memory address space.

DMT - Display Monitor Timings - defined timings established by VESA.

EDID - Extended Display Identification Data is a VESA standard data format that contains basic information about a monitor and its capabilities, including vendor information, maximum image size, color characteristics, factory pre-set timings, frequency range limits, and character strings for the monitor name and serial number.

GTF - Generalized Timing Formula; a method of generating general purpose display timings by formula instead of by a fixed table.

MOIRE - an optical illusion that occurs when many parallel curved lines are placed near each other to produce a pattern in the eye of the viewer that does not exist in reality.

RAMDAC - (Random Access Memory Digital-to-Analog Converter) The chip on a video card that converts the digital image into an analog signal. The RAMDAC maintains the color palette and determines refresh rate. The faster the RAMDAC, the higher the possible refresh rate.

Refresh Rate - The rate at which a monitor redraws the image on screen. It is measured in Hertz (Hz).
