P.S sorry for the bad Language. Also I noticed a burn-in on the high right corner of the monitor after using 120hz for a while, is it normal or what O_O ?

You can use refreshrate multitool to test the frames. Searching for "refreshrate multitool" in google and it will be one of the first links.

Also the burn-in is actually color retention is normal and will go away. There is a good deal of good information in this thread on how to prevent and/or fix the color retention if you search "burn-in" or "color retention" in this thread.

Do your displays flicker as if they're changing mode when you launch CS? When using windowed mode it should be totally seamless with no mode changes, and therefore the game has to be using whatever Windows is using. How are you verifying that CS is not at the correct refresh rate?

I have Vsync on. So if my refresh rate is 120, it'll do 120FPS. But I can see a huge difference without on, but it just confirms what I see.

Not sure if they flicker. They do I think when in full screen non window mode.

Just received mine from greensum and it's beautiful

No dead pixels and minimal light bleed, I thought there was one yesterday but I can no longer see it. Couldn't find anything wrong with it. Good thing I didn't pay for a Pixel Perfect version. SWEET monitor. biggrin.gif

Does anyone know if a single GTX 670 2GB can drive 2 Qnix's @120Hz and a third through an active displayport to dual link adapter @96Hz? My primary concern is that normal multitasking and gaming on one of the 120Hz monitors will hit the VRAM ceiling or max out on GPU power.

Odd, I never use vsync personally but I tried enabling it in CS: GO (set to triple buffered) and it didn't seem to do anything. My framerate was still in the 200's. What happens when you disable vsync?

FWIW, with a refresh rate this high I think tearing is so minimal that it's rarely worth having vsync enabled. It also seems to depend on the game and tearing is more noticeable in some engines. In particular, I think CS looks great with vsync disabled and of course ensures that input lag is minimal which is crucial for a FPS.

I got my AMD card in (a 6970 used to be precise) for AMD overdrive testing. I used http://www.lagom.nl/lcd-test/response_time.php for most of the response time testing. First of all overdrive is mostly not used anymore as with a monitor running under 8-10ms response time the side effects are said to not be worth it due to reduced possible monitor live time and color precision issues. I myself thought it was worth 20 bucks to test on this monitor given its already very good response.

First off the testing method i used was the lagom response time pattern being shot by a high speed camera and refresh rate multitool shot by a high speed camera. The percentages i give are a pixel count from left to right difference in the ghosting effect from each test tool recorded by the camera close enough to see the whole pattern and see the individual pixel with a sharpness increase(which may slightly through off the results but this should be a fraction of a percent or up to 2 pixels, as this is completely indistinguishable to the eye your going to have to bare with me on it)

Stock 100 overdrive gave a 11% difference on average between each color stream in terms of ghosting or response. This is equivalent to the 6.4ms response that was tested in another review(forget the user right now) so the resulting response would be 5.7ms

The 150 overdrive gave a 14% difference in all color bands on average(excluding 80 point grey or blue see below) this is relative to a 5.5ms response from 6.4 stock.

The 200 overdrrive setting just through the monitor into test mode(which took safe mode to fix)

Over my testing i also found that the pixel response is effected just as much by the color retention since light blue or grey gave a anomalous reading ranging up to a 8-11ms response and overdrive made it worse at overclock speeds. After setting the monitor to 60hz the response variance between light grey/blue was almost none existent from the rest of the color spectrum. Not sure what is going on here but it seems the qnix doesn't like light grey/blue(or at least mine).

Overall i could not see any color shift or pixel drag from the resulting pixel overvoltage which does show a good power regulation throughout the panel. Ultimately i still don't think it is worth the risk to go from 6.4ms to 5.7ms.

Hope someone found this interesting and i will be selling a 6970 LOL thumb.gif

I have two GTX570s in SLI. Over GPU power is pretty strained to keep 1 Qnix at 120hz. Given that a 670 is about 150% of a 570 you are likely relatively close to my performance. The extra memoy is good if you were talking about one Qnix as i do see VRAM over-utilization but for 3 Qnix's would be outright bottlenecked both in VRAM and GPU power with 1 670. At 1440p 2GB of VRAM is recommended so for 3 Qnix monitors you theoretically would need 6GB to support the texture size at that resolution. With this being said a titan or 780 in SLI would be advisable for 3 monitors at 1440p and even then 120hz will not be possible in some games or situations.

Why is it UPS's fault that you can't hear the doorbell?
