Would somebody more knowledgable than me please explain the difference between DVI and VGA and what the different standards are for and how they function.
I use my homebuilt mostly for online stocktrading, which is mostly a lot of 2D charts. I'm not a gamer. Will DVI make much or any difference for my uses? I've got 2 AGM 19" widescreen LCD's and may add 2 more LCD's. Should I get ones that have DVI connections also?
I built and am running this:
Asus A8N 5X
AMD X2 3800
Corsair XMS2048 3200
PNY Quadro NVS 440 PCIEX 16
WD Caviar SE16 2500KS
Samsung 16X DVD+R DVD
Sony IDE DVD-ROM
Samsung 1.44 3.5 floppy
Cooler Master RS 450
Cooler Master Centurion 5CAC-T05
Logitech X-230 32 Watts RMS 2.1 Speakers-OEM
2 AGM CW 19" wide screen monitors
MS XP Pro
For your purpose, i don't think you'll see significant differences. DVI is good for Photo editing, movies, games.
For getting new LCD and comparing between VGA or DVI, this is up to you. You can check the prices though. Most LCD support VGA and DVI, sometimes only DVI, sometimes only VGA. Their prices aren't much different.
