"Good for everything but FPS and fighting games"3.5 starson by Koshinn
Very sharp picture
Above average color reproduction
Cons: 6 frames of lag (1/10th second or 100ms) over HDMI
9-10 frames of lag (150-166ms) over DVI-A
That means playing single-player or local multiplayer games is like online, and online is just that much more laggy.
Summary: As fighting game players know, 6 frames of lag makes some moves guaranteed and many others almost impossible to see before they hit. As FPS players know, 1/10th of a second is a LOT of time to be missing.Upon further testing it seems I jumped to a conclusion. The monitor only lags over DVI-A, not HDMI. It seems Street Fighter IV is culprit here, it lags 6 frames consistently over all systems and televisions I've tested in the last 24 hours. It's strange that no one has found this before.
If you're not in a very competitive category in either of those two games, you probably won't notice it. If you're playing any other type of game, doing office work, media work, or just surfing the web, this monitor is perfect.
I wish CNET did in-depth input lag tests rather than just by "feel." It's about time that a major review site started releasing test numbers on input lag to put manufacturers in their place.
There are two ways to test input lag that I know of, both require a camera with 60 fps video recording or faster.
What I did was played a fighting game (SF IV) with known attack speeds in frames. In this case, Ryu's close LP is 3 frames. You setup the camera such that you can see the screen and your keyboard. Hit the attack key as quickly as possible, leaving your finger down. You count the frames it takes from your finger pressing the key until the attack connects, then subtract the known speed of the attack - 3 frames. I counted 9 over HDMI and 12-13 over DVI-A. Thus, 6 and 9-10 frames of lag respectively.
The best test, however, requires a splitter for your output. You run a stopwatch on your computer with miliseconds displayed, then split the output, one to a CRT and one to the test monitor. CRTs (not HD TVs) via VGA have zero input lag generally, but use the previous method to test them first. Then use a camera with a high shutter speed (with both the control and test monitor in frame) and basically take a series of pictures and average the difference you see in the stopwatch on both screens. That'll give you a much more accurate input lag reading, but in general, frames are enough... a frame being 1/60th of a second, or the speed at which PS3/360 games run and the max refresh rate of most LCDs.

I'd give this monitor a 4.5 star rating now; it still doesn't show your bios and other startup information when connected through hdmi or dvi-a.
