I had bought a VGA splitter two years ago and I had never broken it out of its cheap plastic bag. I had also bought that Prad program SMTT a while back but never broke it out of its (you guessed it) cheap plastic bag. So I finally got this going in this configuration GTX 480 ---------> DVI to VGA adapter ----------> VGA Splitter ----------> Connector 1 to CRT VGA 1, Connector 2 to LCD VGA (U2412M, then NEC LCD2490WUXi2-BK) So I finally got to use them. Below are the shots and hopefully an explanation following. I'm only including three shots and I'll explain why after. Two are inverted to make the "dark numbers" easier to see: Tests were run at 1920x1200@60hz. P1210 CRT on the left vs. the U2412M on the right shows very little, maybe 8ms of input lag. These shots are completely representative of every shot I got. I took over 200 shots in total. Some at 1/60, some at 1/125 and 1/200 exposure rates. This pattern never seemed to vary. Always two numbers on the U2412M were the same as the CRT numbers, whether top or bottom. Even the ones that weren't the same, you can see the beginning of the numbers appearing that will match the CRT. If you look at the last, non-inverted pic, the CRT is showing 68.830 bottom, 68.836 top, and the U2412M is showing 68.819 > a slight image of 68.82x and a third image coming in of 68.836. I would say it's half a frame of lag, but really no, or a couple of ms of lag + response time "delay". So I think you can say this is probably a pretty good gamer's screen, because lag (lag+response time) appears to be 1 frame or less. By the way, I tried higher refresh rates over VGA. They worked fine on the CRT, but no-go on the U2412M, so I doubt it's going to support them regardless of interface. Checking specs on the panel (which someone also stipulated earlier in this thread) it is limited to 60hz max. P.S. to ensure this process was accurate I connected my NEC LCD2490WUXi2-BK which is pretty much known to have somewhere between 1-2 frames of input lag. On this same exact test from video card > VGA splitter > dual screens, the NEC was always 1 - 2 frames behind the CRT, and none of the four numbers on both displays were in sync, unlike the U2412M versus CRT comparison.
