I have a GTX 680 with two DVI ports and an HDMI. well lately my HDMI stopped working properly on my monitor, and the only port left on my monitor was a VGA, so i used the DVI/VGA adapter that game with my gpu and am now using VGA cable instead of the HDMI, but i notice no difference at all. i do a bunch of hardcore gaming and i was wondering, is there any real visual difference between the two? i know about sound, know that VGA is analog and HDMI and standard, etc... but like is there any actual picture quality differences between the two? google has not been very helpful with this question.
