Glossary

Analog Input — The old fashioned way of connecting monitors to computers, uses a 15 pin cable for most PCs.

ASV — Advanced Super View. A display mode for LCDs.

Cd/m2 — Candela per meter squared. A measure of luminescence.

CRT — cathode ray tube.

Contrast — The difference between light and dark shades.

Contrast Ratio — The measurement between light and dark shades on an LCD.

DLP — Digital light projection — this technology is an evolution of projection and rear projection that may totally replace rear projection TVs in the near future.

D-Sub (15 pin) — The analog connector between the video card and the computer is more properly referred to as the D-Sub 15 pin cable.

DVI — Digital Video Interface. This interface is the preferred connection when dealing with LCDs. These come in three forms: DVI-D, DVI-I and DVI-A. DVI-A is analog signal over DVI; DVI-D is digital over digital; and DVI-I is the most versatile, capable of digital or analog signal.

FFS — Fringe Field Switching, one more LCD Display mode.

Ghosting — The type of signal interference associated with harmonic oscillation over the cable or connector. The result is usually an “echo” of the original image superimposed across the screen.

IPS — In Plane Switching. An LCD display mode.

LCD — Liquid Crystal Display.

Luminescence — The brightness of something, measured in candela per meter squared.

MVA — Multi Domain Vertical Alignment. An advancement on the traditional VA display mode.

Native Resolution — The monitor physically has a certain amount of pixels wide and tall. Typically, this is usually 1280x1024 on larger displays. The native resolution is the resolution your display can handle without any scaling issues.

Nematic phase — The process of twisting liquid crystal substrates to allow or inhibit light to go through.

Nits — the improper name for candela per meter squared. (Lumiensnace)

OSD — On Screen Display. The menu for a monitor.

Pixel — The cluster of Red, Green and Blue sub-pixels that create the illusion of a full color spectrum.

PVA — Patterned Vertical Alignment. Another LCD display mode primarily developed by Samsung.

Response Time — The time (in milliseconds) for the pixel to fully untwist and then twist (or go from black to white and back to black). The “rising” (Tr) component is the time from black to white. The “falling” (Tf) component is from white to black.

Scaling — An LCD monitor contains only so many pixels in the display. Therefore, displaying an image that is not the exact same resolution dimensions will result in an image that is skewed and distorted.

Sub-pixel — A single liquid crystal in front of a red, green or blue filter.

Streaking — Similar to ghosting, streaking occurs when interference along the cabling or connectors begins to comp

Substrate — The heart of the LCD. This is the glass sandwich that holds all the transistors and liquid crystals.

TN — Twisted Nematic. An older LCD display mode.

Viewing angle — The measurement that refers to how viewable the screen is at extreme angles. Some manufacturers list angles like 120 degrees, which means 60 degrees left and right. Most simply list values like “70 degrees left and rights.”

    Aaaahhhhh! Dr. Strangelove I presume.

    what's up with all the posts...

    it's really freakin me out...

    I'm used to the twice a month ones...

    Well, the bright side is this is suppose to be a boring strtch to Athlon 64 and Prescott release, wonder how many we'll get then.

    Yup. I gave up on waiting for a quality LCD for gaming. Bought a NEC FP912 to last me the next couple of years.

    Maybe LCDs + gaming will be an uncompromised reality then.
