Anyone can talk about these 3 Viewsonic LCD? I not really know the different between them even I had check their website

VA2223WM 1920 x 1080 (F/HD) 16,000;1 5ms 300 cd/m2 Analog/ DVI
VX2233WM 21.5" 16:9 1920 x 1080 (F/HD) 18,000:1 5ms 300 cd/m2 Analog/ DVI
VA2231WM 21.5" wide, 1920x1080 (Full HD), 100,000:1 (DCR), 5ms, Analog & DVI, Speakers

I looking to get 1 of this. Any suggestion which model are good for gaming from above list? I going to use Gigabyte 460 1GB OC card for it.
(I think VA2223WM and VA2231WM coming without DVI cable).
Is that any different when usin VGA cable compare to DVI-D cable?)

Anyone can tell me is that much different when connecting the LCD by D-Sub and by DVI-D?
As from last 2 thread, I looking for viewsonic LCD but it coming without DVI-D cable, so I will going to use D-Sub, is it recommended to use DVI-D. Any gain in quality? Normally what is the price for DVI-D cable ?

DVI is old school but currently some new LCD still not even come with DVI cable.
