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?
