bytemangler 0 Posted January 29, 2002 I'm looking to get couple of flat monitor (LCD) for work. I need to know the benefits DVI over Analog. Anyone an expert in that area?? I'll be getting a matrox G550 that has DVI out to work with it. Share this post Link to post
hargrovm 0 Posted February 3, 2002 I have the same video card - pretty pleased with it under Win200/latest drivers. I don't use the DVI port though as can't afford flat panels. Ok don't quote me on this but the I think the advantage of DVI over Analogue is something like. The Video card starts with a digital representation of the image numbers in memory which it then converts to an analogue signal RGB - which is fine for a CRT monitor - because they're essentially analogue. However the flat panel is essentially digital - LCD's - large numbers of Red Green and Blue Pixels either on or off so the flat panel has to convert the analogue signal back to digital to display it - in all this conversion - the reasoning goes - you'll get some signal degredation so the DVI avoids all this by taking the Digital signal direct from the video card and gives it to the digital processor of the flat panel - avoiding all the analogue conversion in between - I guess giving a better image - Whether you'll see this I don't - but thats my guess at why DVI is better for a flat panel. Hope this helps Share this post Link to post
