Oddly enough is some games will crash on laod screen without two bridges installed, so people take note if anyone is having games crashing on start up or when you apply 120hz then consider using two bridges.
This really goes against all logic I previously would have had about how crossfire works. The reason I'm sad is now my third GPU is useless unless I bump it down to 60hz and I don't need three GPU's for 60hz.

You guys with two bridges installed already can you try to do more testing with one bridge vs. two bridges @ high refresh rates. Just so we can get more feedback about this ?

It's required for crossfire and 120hz@1440p in my experience, I was the first one to find this out, it took me literally 12+ hours of testing until I realized it needed two bridges, I posted about it multiple times in the catleap thread trying to spread the word, and I can definitely confirm the crashes in certain games with only 1 bridge attached

Glad you got it sorted Pap and my hunch was it was those games. And, yeah, I meant CS Source, by the way. Considering it's practically given away by Valve (if you don't already own from back when) I figured you had it and knew for sure it caps right.

Don't forget about Nvidia Inspector for further control and tweaks too. Can do much more with it than just the NV CP.

Thanks for confirming. It's funny though I have talk to some people that refuse to believe it helps to use two bridges.
I tried booting with three cards and a extra bridge to bride the top and bottom cards and it BSOD on boot frown.gif
So three AMD GPU's and 120hz 1440p is not going to do anything with only one bridge.

I myself just picked up one of these off of Amazon.com (http://www.amazon.com/QNIX-QX2710-LED-Evolution-2560x1440/dp/tech-data/B00BUI44US/ref=de_a_smtd) after finding this particular thread. I'm not exactly too worried about the dual-link DVI requirement, I've got an HSI RadeonHD 7770 that should handle that... and plenty of DVI cables...

Rather, I do have a question that I did not see answered in this thread (at least with a search of the thread). I have a couple of HDMI -> DVI adapter cables, including some that support HDMI -> Dual-Link DVI. I'm curious if anybody else has tested these panels with such a cable, and if so, is it known to work?

I need to buy one more so my tri-monitor setup will be complete. Then I need a better video card lol.

these monitors only have a dual link dvi input..

3.No real issues as long as you don't over do it..I just got my Qnix today and its amazing..
4.I don't know how you would consider it..I can for sure tell the difference in gaming and even in just dragging around windows..
5.I have a glossy and a matte and i am sending back my glossy Monoprice.My new one is matte..I think when reading text in a dark room glossy just looks sharper.But if there is alot of light in a room then it distracts you from whats on the screen..I personally love this new matte Qnix..

Thanks for replying, I have a few more questions tongue.gif

6) Do you know if the panel is 6 or 8 bit? I heard it may have been undeclared by Samsung and is a form of e-ips?
7)I don't like seeing my reflection I suppose so that means i should go matte (semi-gloss) but does it take away from color, contrast, etc.?
8)How noticeable is graininess with the matte vs gloss if you remember and I will be sitting about 1.5 feet away.

case in point, an HDMI to DVI cable: http://www.amazon.com/gp/product/B004S4R5CK/ref=oh_details_o00_s00_i00?ie=UTF8&psc=1

HDMI and DVI use the same exact picture signaling method. The only difference is that HDMI can also carry an audio stream.

On paper an HDMI -> DVI Dual-Link cable should be capable of powering this monitor. I'm asking if anybody else (here) has tried this on-paper approach first.

HDMI is not compatible with Dual Link DVI. In general, this will not work. And you will definitely not be able to overclock anywhere near 120hz .

That being said, one person (ToastyX) has managed to get it to work with an Nvidia/AMD card via HDMI->SL-DVI, at 60hz. Barely. It was very unstable, on the ragged edge of working and not working. You should be able to to do it just fine at pixel clocks <165mhz though (~42hz refresh rate).
