I'm not sure if it's my monitor (Dell SP2309W), but I have a curious issue when using DVI on it. When I use HDMI, image seems clear and crisp, but using DVI makes the image a lot brighter and even a bit offensive to see. This has happened on 2 different computers, with 4 different GPUs (2 AMD 2 Nvidia).
I would use HDMI just because it's a more "future-proof" standard, since most laptops are foregoing VGA and DVI, all modern consoles use HDMI, and most high end GPU's are either focusing on DP, HDMI and dual DVI at the professional ranges.
EDIT: found a couple articles
about that. Seems that AMD and Intel, among with others won't be supporting VGA and DVI by next year, maybe with their respective 20nm lineup upgrades.Edited by Starbomba - 4/11/14 at 10:48am
