DVI Output versus VGA Output

[dzachau]

I just bought a new Dell LCD monitor. It is the first monitor I have bought with an option to use DVI output. I also have a video card that has a DVI input. Could someone tell me what the difference is between DVI and VGA outputs, and if it is better to use DVI if you have the choice?? Will I notice a difference in picture quality while watching TV or movies on the monitor??

DVI is a straight digital connection, VGA is analogue. DVI should give you a better image.

What will it cost you to plug in the DVI and see for yourself ?

DVI is a digital format and VGA is a analog format. Since the computer starts with a digital signal, DVI eliminates a conversion step and results in a generally better image. Check here for some DVI info:

Thanks. Good point on just plugging it in! However, my monitor is hooked up to my computer with a longer than usual VGA cable and physically located in another room inconveniently positioned under a desk. Before buying a DVI cable that is long enough and crawling under my desk I thought I'd ask. Thanks again for the input. Anyone know of the best place to buy long DVI cables??

Disregard my last question. Just saw the link Redwudz sent me. Thanks very much. Looks like cable length may be an issue for me.

The sales guys will say "DVI is better." No much diff to the naked eyes.

you may be limited to vga as the cost of a long dvi cable may be too much. if you do get vga cables, try to get a single line if possible and make sure it is good and thick. Thin vga cables that are piggybacked off each other create a blurry ghosted image on the monitor.

The technology is already out to transmit video wirelessly but it comes at a higher cost. pretty soon we won't have to be crawling around in our attics anymore
