Below is a small video file of 40% gray, play it full screen at 60Hz and then again at the highest refresh rate you use. Do you see any difference in the UNIFORMITY of the screen. That is, I don't care if the gray changes shade a bit, that's expected as the gamma shifts at higher rates, but mine gets funny stuff standing out if I use higher refresh rates as seen below:



This isn't backlight bleed, but the inability for some pixel regions to respond at the same speed at these higher rates (or so I guess).

Slightly underexposed @ 60Hz to exaggerate uniformity. All taken at same shutter speed/fstop/iso.

Anyways, I haven't really tested it much but I tried another cable on one of the monitors and there doesn't really seem to be much of a difference. I'm really assuming it's the monitors itself that aren't capable of going any higher.

Interesting, so my monoprice 10FT 24 AWG cables work at 120Hz, so do your 28 AWG ones (mostly, did you try swapping your cables on the one that didn't do as well?), but one person mentioned theirs failed with the monoprice 28 AWG cable. I was hoping it was as simple as using the 24 AWG cable, looks like it might be just dependent on the monitor.

I wonder if its the actual chips on the board that are crapping out at higher refresh rates for some (lower binned parts?) or if it's wire/shielding or soldering joints. You might be able to "fix" one if it's the later.

Interesting, I was getting scan lines at 120Hz with the stock cable so I just purchased the Monoprice 24AWG DVI cable. I went with a 24 over 28 because the cable is thicker I thought it may be a better overclocker. Hopefully that will get rid of the scan lines! I hope that the cable will make a difference, and it's not the monitor.

Also is there any way to get rid of a green stuck pixel? I tried UDPixel, I tried pushing on it, but it still won't go away. frown.gif

IMO these are not as well rounded as Catleap 2Bs, but given that these are readily available and can OC to 96Hz these are the next best thing.

I wouldn't use one of these even at 96Hz without using a calibration (many available here) as the gamma is just too far off. It's insanely far off anywhere from 100Hz and up. I suggest you try out a cal and then tweak to your liking.

Probably not. I have one as well.

Looks like it's fairly prevalent then. Can anyone post pictures like this that DOESN'T show uniformity changes at higher refresh rates? And if so, can I have the CRU profile values you used?

I just wanted to post some photos of triple QNIX's at gaming........

I'm planning on getting an i1Pro or Spyder4 Pro to calibrate better.

BTW, hulustar just replied that they still have 'event monitor' -- the first 100 pixel perfect glossy/matte.

@halodude, damn, jelly here! Have you tried overlapping bezels to reduce the gap? The bezel on this thing is almost as big as on the Catleaps frown.gif

halodude23, that is just sick. You can actually justify some serious multi-GPU horsepower, unlike most people.

Finally added descriptions to all my dismantling videos (threw one out too) and arranged them into a playlist. Maybe we can get the original post on this thread updated with this new link?
