Another AOC user here, absolutely no problems with mine. Hits 100Hz without any issue. Couldn't be happier really.
21:9 is the future of gaming!
.LG 29 inch here, I play games at 75hz using my hdmi cable connected to my sapphire r9 290 Tri-x, Iv been playing battlefield 4 set on ultra and 2xAA, everything runs smoothly, game plays in full screen, also movies I watch that's HD will be played in full screen also, colours on my panel is amazing, only thing I hate is the touch sensitive buttons
.And ViRuS2k, still waiting for those frame skipping pictures.
Thanks Temp.sgk.
Have you tried using DisplayPort and comparing the image? Aside from the upcoming HDMI 2.0 spec, HDMI doesn't actually natively support the 21:9 aspect ratio. What you're seeing on the LG is likely 1920x1080 upscaled to 2560x1080. If you don't have anything to compare it to it can still look 'OK', but you should really test using DisplayPort and see if you notice a change.

Are you actually getting 100Hz "stable"? My Dell does 100Hz but you can see the cursor skipping on left to right movement, highest mine works properly is 80Hz IIRC.

I picked up the Dell U2913 a few weeks ago. Absolutely sublime monitor! It's only got a 60Hz refresh rate, but unless you're doing some intense gaming you won't notice the difference. The colours on this monitor really stand out for me!
Overall I'd rather have an IPS with much better colours than a TN unit that is slightly smoother (if you have the gfx power to push it).
Agreed, so is the AOC considered class 1 for input response time ? if it were say reviewed on TFT Central ?
I've seen the AOC response time on a couple reviews being very high (30 ms +) and that's not good at all.
Got the Dell earlier, easy setup just install the software for the text to look good. No issues with lag that I have noticed, not sure if they have updated firmware/revisions but this is on par with my old TN Panel on response times (less than 12 ms). Colours are amazeballs, so is Dells Customer service.

i took a few screen shots the other night and yes there is frame skipping going on but its so small that i cant detect it when watching movies or gaming or desktop or even cursor stutters.
i experiance none of that.
right up to 75hz no frame skipping at all.
100hz and 120hz have frame skipping but like i said no one would notice it hell if it wasn't for that test i wouldn't notice it...
and the only way to see it is to slow a camera shutter speed down and take a snap, thats why a camera is used in the first place to detect it, bet ya the human eye cant lol
