I am looking at 2 main selections from my distributer and they are Samsung 170T with a DVI interface, vs Viewsonic 170G with 3x video accelerator and analog input. Which is better? If ibuy one of these things, i want something that cna handle video, the analog 3x sounds like it is accelerated to handle that, but with DVI, there is no conversion process, with this in mind is there still a lag in the video? Which is fast the 3x or DVI?
Well converting from analog-Digital won't affect the response time or anything. It just affects picture quality, so I would go for DVI. 3x from Viewsonic is just MVA technology, which has serious color ramp problems. Definetly don't get something w/ that (I had one w/ 3x, and it was horrible. This seems to hold true for all w/ MVA).
What happens with MVA monitors (from tests I have seen/read) is that rather than a color ramp (I assume you know what this is- starts of black, and as you go down teh pic it becomes white, or vice versa) the monitors with MVA represent this sort of image in bands; as if you were running it in 16 bit or even lower color. This I have found to be for MVA technology, as all the monitors I have seen tested that use MVA have had this problem, and they were from different companies.
I just went to my lab and tested the fujitsu 15, 17.4 and 23.1" MVA panles, and they do not exhibit the problem you describe. I use the Displaymate test software that has test patterns showing that show the 256 gray scale and color scales. The gray scale and color scale test shows a smooth transition thoughout the 256 shades.

Short answer is yes. Sine we are an OEM, I review monitors from all of the major manufacturers. I also review monitors for corporations who contract with us to help thier IS department spec in products. See the link below.
