RE: Custom Resolution Utility (CRU)
I'm overclocking the QX320QHD that just came in and I can definitely say everything after 75hz (and it does OC to 87hz) adds horizontal lines to the display. However, it's really hard to tell whether they're at the top of pixel or the bottom of one. Maybe I can get a magnifying glass.

I don't have photos of that, but here's an Imgur album of framerate test photos taken at 87hz.
What's with the double-lit squares? Same frame being displayed again? Highest I've tested so far without this problem is 75hz. BTW, on Windows 7 there is a bug in Chromium that's been closed/won't fix about how it only renders at 60fps, even the desktop refresh rate is higher. Not sure why it does this, but for now the best testing I've been able to pull off was with IE11, all programs closed, CPU clocked to the max at 4.3ghz with Cool-n-Quiet disabled

here's another album of tests at 75hz. At 75hz, no double-rendered frames, and no horizontal lines running across the display at each pixel.

Regarding the horizontal lines, is there any porch or width I could tweak to handle this? What is going on to cause this? I guess I'll go read about DVI protocol and see if I can't intuit what's going wrong. It seems like every 3-4 horizontal rows of pixels there's a 4th or 5th that's lighter/whiter on a light grey background (like Chrome browser menus).

Here are my settings:

Anyway, I got my new QX320QHD, I plugged it in, great monitor, very nice colors. I connected it with the dual link DVI that came in the box. The whole reason I got it was so I could overclock it, as per the widely circulated screenshot on Amazon here (bottom photo on the left sidebar): https://www.amazon.com/dp/B00KVZMUYI/?tag=mtests-20#ad

I actually got the monitor here because lower price, I am 99% sure there's no difference as they are the exact same model: https://www.amazon.com/dp/B00O0UTCPA/?tag=mtests-20#ad

I got the monitor, loaded up CRU, added custom resolutions, the first with 85 hz 1440p and the second with 720p 100hz (to see if lowering resolution would allow higher refresh). I also removed the pixel clock that's in the AMD drivers. I rebooted, changed the refresh rate in AMD Catalyst Control... and black screen on 1440p 85hz!
If 85 Hz is listed and you're able to set it, then it's working properly and your particular monitor can't handle it for some reason.

No visible frame skipping, so I loaded up the Test UFO frame skipping [http://www.testufo.com/#test=frameskipping], but it identifies my frame rate & refresh rate as 60hz! I tried a bunch of different resolutions in CRU, including 1440p 65 hz and 720p 65 hz, but every time it still says 60 frame rate and 60 hz refresh. I can provide screenshots tomorrow if necessary.

I have a prebuilt with a i7 4790 and R9 270, and my OS is Win 7 Home Prem. Those shouldn't be the issue unless I'm completely off.

Thanks so much for the help in advance! I really appreciate it!

Edit: screenshot of amd catalyst control saying 75hz while testufo says 60hz.
Make sure you're using one of the Aero themes. The UFO test requires desktop composition to work properly, but your screen shot shows you're using the Basic theme, which disables desktop composition.

That would make a lot of sense. I'll test it with Aero this evening when I have a chance. Thanks ToastyX!!

see this: https://code.google.com/p/chromium/issue...?id=431487

it's closed as won't fix.

there's also this, which I haven't read, and probably won't. For now, I use IE11
