For Skyrim a 10ms difference in response time doesn't really matter, the game just isn't that precise. Keep i mind the u2711 has a rt of 24ms which is 1/40th of a second, that's not bad.
Anyway I run Skyrim with two 580s in sli (1.5 gb though) on a 2560x1440 monitor. It's really cpu bound more than gpu bound, and I'd expect you'd get somewhere around 30 fps. I'll try disabling SLI and see what I get.
Response time is not the same as input lag. There are plenty of 2ms response time monitors with 25 ms of input lag. I think the u2711's rt is closer to 8ms.
From most reviews Samsung PLS tech has some pretty awful backlight bled. I'd avoid it.
Anyway, in skyrim with a single 580gtx 4x aa and the settings above "high" but under "max" I average around 40 fps, and never get below 30. With 2 580s in sli, I average around 52, and never drop below 35.
FYI I have an hp zr2740, which has a response time of 12ms and input lag of around 10ms. It's very quick responding but has a bit of motion blur.
How can it have a lag of less than it's response time you ask? First, I think response time it there and back, lag is just there. Second, lag is measured relative to a crt, which has a lag of 8 (due to the scanning of the electron gun), but no one ever factors that into their reviews.
You say the Samsung PLS has awful backlight bleed? Damn, thats frustrating - just when I thought I had found the best. It may just be specific to the region and batch though, I have not heard any serious complaints of this display in Australia (where I am).
Can you recommend something that will rival the S27A850D PLS?
Wait a month, both Asus and LG showed new 27" IPS panels at CES, and Dell is likely to have a u2712 out soon.
Honestly, I can't recommend the zr2740w just because it has a ridiculously aggressive AR coating. If you know what AR coating is, and you've seen it, and you're okay with double the normal amount, get a zr2740w.
The dell u2711 is the only 27" panel I haven't heard of anyone regretting buying. 24ms of lag really isn't a big deal in the grand scheme of things, sure it's 14ms more than the very fastest panels, but it's not the only source of lag (get a wired mouse if you hate lag.) Overall, most systems have 80ms or so of total lag, so 14ms isn't a huge deal.
I've also owned a 26" Planar px2611. It's a great 26" monitor at 1920x1200, but mine died after 2 years, so it's a risk.
You make a valid argument. However after extensive research I still think the Samsung is the way to go, providing there is no significant backlight bleed in the unit I recieve.
I can't ignore your logic in waiting though, so I will do some further reading on the yet to be released Asus and LG models.
Thing is, I have heard we won't see the Asus (not sure yet about the LG) for quite a while here in Australia and I really need a better solution to my current 27" TN (I know, I know - what was I thinking!?) for colour intensive work very soon.
Regarding the crazy thick coating, well I have heard there are certain issues here with the U2711 that I definately want to avoid so it's really not an option.
Thanks for all of the informed advice, MagicPants!
