To me, I think it's one of those things that if you use DVI for long enough, you definately notice TFT or LCD panels using VGA. I have a 19 inch tft lcd with dvi and I can tell when my monitor's on a vga output, and 9 times out of 10 i can tell when other lcd's aren't using DVI. True, it's a small change, but i've grown to notice it. That's my 2 cents.
one thing i don't understand is why all lcd's don't accept dvi input. after all, it's more of a native signal for lcd monitors which are all digital. is it just because equipping the actual dvi port with it's 30+ pins adds like $10 to production costs?
Originally posted by Zedric Probably. The analogue interface has to be there anyway for compatibility, so you can't make a cheap DVI-only screen. And two interfaces cost more than one. Not only because of the extra plug.
yeah, but i don't think i've seen a 15" lcd yet that even has a dvi plug.
which leads me to believe it might be resolution related as well. i'm thinking the higher the resolution, the more an analog signal be susceptible to evil things like shadowing. so larger lcd's with their 1280x1024 resolution and higher can benefit more from the dvi interface.
back to the basic topic, dvi also provides better color accuracy. in addition, you don't have to worry about centering the screen, though a lot of lcd's have an auto-center feature.
when you have a video card with a dvi connector... and it comes with a dvi-to-vga adapter, using that adapter puts the card into vga mode. in other words, the adapter doesn't do any work itself, but rather just cue's the card to outputting a vga signal out of designated pins on it's dvi port. so, exact same quality as a pure vga port.
Ep, glad to see you come back and tidy up...did want to ask a one day favor, I want to enhance my resume , was hoping you could make me administrator for a day, if so, take me right off since I won't be here to do anything, and don't know the slightest about the board, but it would be nice putting "served administrator osnn", if can do, THANKS
