Abbreviation of video graphics array, a graphics display system for PCs developed by IBM. VGA has become one of the de facto standards for PCs. In text mode, VGA systems provide a resolution of 720 by 400 pixels. In graphics mode, the resolution is either 640 by 480 (with 16 colors) or 320 by 200 (with 256 colors). The total palette of colors is 262,144.
Unlike earlier graphics standards for PCs -- MDA, CGA, and EGA -- VGA uses analog signals rather than digital signals. Consequently, a monitor designed for one of the older standards will not be able to use VGA.
Since its introduction in 1987, several other standards have been developed that offer greater resolution and more colors (see SVGA , 8514/A graphics standard, and XGA), but VGA remains the lowest common denominator. All PCs made today support VGA, and possibly some other more advanced standard.
Short for Digital Visual Interface, a digital interface standard created by the Digital Display Working Group (DDWG) to convert analog signals into digital signals to accommodate both analog and digital monitors. Data is transmitted using the transition minimized differential signaling (TMDS) protocol, providing a digital signal from the PC's graphics subsystem to the display. The standard specifies a single plug and connector that encompass both the new digital and legacy VGA interfaces, as well as a digital-only plug connector. DVI handles bandwidths in excess of 160 MHz and thus supports UXGA and HDTV with a single set of links. Higher resolutions can be supported with a dual set of links.
Same with my GFX cards. No point in using the converter since you will not get any improvements on your existing analogue TFT monitor.ElementalDragon said:....ok... my Video card has an output for DVI. but.... my LCD has a normal old VGA plug. ..... i'm guessing that if i use the DVI to VGA converter thingy that came with it, i won't get any improvement. am i right, or no?
You may also get me one as well ... for testing purposes of course.ming said:Hmm.. I've resisted getting a TFT monitor with the extra DVI cable connection. Maybe it's time to check one out.
I have doubts that it'll make a major difference to me, but worth a shot I guess.
