I liked just about everything else about the u2312hm though, especially the viewing angles. I want to be clear that there were no obvious trails or "ghosting". Tried several games, running at 60 FPS, and the motion blur was distracting. I also tried my PS3 with GT5 and saw a big difference in motion blur between my TV and the u2312hm. I decided then to send back the u2312hms.

I was ready to get 3x 120Hz monitors but I keep reading these forums and I can't decide. The problem is that there are too many posts that indicate that "TN is trash". I've never owned a TN monitor either. I will say the u2312hm was great in everyway except for motion blur. Maybe the PA238Q is better because the trace free feature is configurable? I also keep reading that a 120Hz is useless if your frames are not above 60. I'm not sure this is completely true. Having more frames will make motion look smoother, but it's the motion blur(related to pixel response and RTC) that bothers me most. It looks like most 120Hz panels have average response times of 2-4ms. This is significantly less then the 8-9ms average response time of these eIPS panels. This alone should result is significantly less motion blur.
Great response, thx. Sometimes I wonder whether I'm being too picky. tongue.gif

Haven't really noticed game-breaking trailing or motion blur with my U2312HM. Not as bad as it was with my Samsung, if any.

What model of Samsung TV is it?

Generally older Samsungs have PVA or S-PVA panels which are not reputed to be ultra-fast in terms of pixel response. Strange. Thanks for that.

Driving 3x120hz screens at one time via surround gaming is going to be nearly impossible on today's hardware.

Samsung LNT4069F. It's one of the first 120Hz models. It's a PVA panel with a advertised pixel response time of 6ms. I originally went with the u2312hm because I thought the pixel response time could not be worse than the Samsung, mostly due to its age. However, the u2312 had much more motion blur. I noticed immediately when playing GT5 and iRacing. In "PC mode" with "Game Mode" enabled the 120Hz frame interpolation is off, so it just repeats each frame twice.

I really wanted to keep the u2312hms but I just could not stand the motion blur compared to the TV. One reason I wanted to upgrade from the TV is that I wanted a better pixel response time. The u2312hm performed similar to my u3011 with motion blur. Like I stated previously, I think it's the pixel response time, not the 120Hz drive that makes helps with the motion blur. The TV is only really displaying 60 FPS, but each frame twice.

Driving 3x120hz screens is possible depending on the game you are playing. This is very possible in iRacing. Even with my old gtx260 SLI setup I could get +120 FPS @ 6040x1080.

I ran some of the pixperan motion tests on a few monitors that I have for comparison.

For the pixperan car chase at default speed:
u2312hm - fairly crisp double image with a slight trail(RTC artifacts)
u3011hm - fairly crisp double image with no RTC artifacts
u2407 - fairly crisp double image with very bad RTC artifacts
LNT4069(120hz AMP off) - crisp double image with slight color trail
LNT4069(120hz AMP on) - smooth single image with very light RTC artifacts

On the readability test, I could see the letters with the LNT4069 better on a speed of 20 than I could with the u2312hm on a speed of 9!

This tells me that a true 120Hz monitor, with 120 input, is going to have much smoother motion. The difference is incredible even with my fake 120Hz TV.

Motion blur on the other hand is due to the pixel response and RTC. Based on what I have seen with all these monitors in front of me.
LNT4069 > u3011 > u2312hm >> u2407
