View Full Version : DVI vs. D-SUB

Can someone please tell me what the difference between these 2 is on a TFT monitor?
I mean, i know one is analog and the other one is digital and that everybody is recommending DVI, but i want to know exactly what DVI has over D-SUB. Not theoretically but practically. Will i see a difference between D-SUB and DVI? Cause right now i'm looking at one and it looks the same as my D-SUB TFT...

Much better picture clarity, particularly on higher-resolution screens. You may not notice a big difference on a 1280x1024 TN panel.

Color Separation, more vibrant and fonts are more vivid.
I use DVI and i used D-sub and can tell a big difference in games at higher detail.
DVI cabling costs more but is worth it.

Thanks for the replies!
I was thinking of buying a Samsung 19'' TFT but had to choose between 2 models : a D-SUB one and a DVI one. The DVI is obviously more expensive, and was wondering if spending the extra cash is worth it.
Anyone else want to give their opinion?

DVI comes straight from the video frame buffer and will not suffer any kind of image-quality effects inherent to lower-quality RAMDAC components. In fact it doesn't use the RAMDAC at all, DVI completely bypasses the RAMDAC and sends a pure digital signal to the monitor. No conversion from Dig->An->Dig is required.
I can remember the old days of the Ti series and some other cards just totally sucking in terms of D-Sub quality especially at higher resolutions. As others have said the color reproduction is finer, but again all this is due lack of RAMDAC requirements.

Yeah, definately go for the DVI. Everything is way sharper and the colours are accurate. With D-SUB you will get blurry text and poor colours. I can't stand using D-SUB with my LCD. DVI FTW!! (nana2)
