im currently at 459 pixelcock with the default shipped DVI-D cable. would you recommend to get the monoprice cable in order to go down to 450?

My results, I've tried a bunch of cables.. Hope this helps.

The only cable I cannot try are the 3ft ones, so its 6ft only for me. I've also tested both DVI ports with all cables.

1. Stock cable, 28awg, , OC to 120hz standard I get horizontal lines everywhere on the start screen. Tried front porch method and noticed a few lines playing games. 110hz is perfect.

2. Monoprice 24awg 6ft. . Basically the same as the stock, maybe even worse. 110hz is perfect.

3. Bluejeanscable.. 24awg 6ft. Worked fine for about a week and noticed some static when opening an app. It must have always been there but it took a bit to notice. 110hz is perfect.

4. Cable Matters 28awg 6ft. OC'd at 120hz on standard and noticed just a little static on top right, all other cable would be unusable on standard. Did the front porch method and tested all of the other issues I had with other cables and so far its been perfect 100% . I may notice something in the future but its been a few days now and I have seen no distortion whatsoever.

So for you guys asking for cable recommendation I've had the best luck with this one:

Hope this helps someone. Your mileage may vary.. thumb.gif

As for the Monoprice cable, there have been mixed results. Some people (like Spartan) were able to reduce their pixel clock using it, but others actually saw better results using the stock included cable. I believe cable length is what maxes a difference more than AWG.

If you're willing to spend the money, go for it, but it is definitely not a guaranteed reduction in pixel clock. Running at 459 shouldn't really be harmful in any way, as its only a slight overclock

I have found no frame skipping in games. Games in full screen take over the screen and generally this seperates it from the secondary screens field of view. This is why in a full screen game if you click on your secondary monitor it will minimize or window the game. However i do recommend turning the secondary display off when full screen gaming to better make use of VRAM especially since you are trying to push 1440p@120hz. Less unused load on the GPU means more power for the game thus higher FPS.

And the cables i got from monoprice were very hit or miss. I ended up finding an old cable in a box at work that got me slightly better than the best monoprice cable. After testing dozens of cables the only conclusion i could draw was keep your cable under 10ft since the length does take a toll on data degradation. The size actually showed that over 6ft required a 24AWG cable and under 6ft 24AWG did just as good. I am currently using a nameless white DVI-D cable that is 28AWG and just under 3ft long.

I would say if you have friends or can get a hold of cables cheap(monoprice may be the best place but there are others out there) to test with than sure but i would go spending a fortune on cables and definitely benchmark the pixel clock first.

thanks for the cable answers.

I got another one for games, I am currently testing which games I have support 120hz, should every game support it? also there is some odd behaviour.

sometimes I have to disable/re-enable vsync ingame in order to see the 120 cap. sometimes i have to go fullscreen, i assume 120 windowed does not work?

wow menu 120 ok - wow ingame 120 ok if going to fullscreen, no 120 if windowed
sc2 menu 60 max - ingame 120 ok if going to fullscreen, no 120 if windowed
diablo 3 60 max fullscreen with vsync on or off - window mode vsync off = over 120, window mode vsync on = max 60 fps ?? does d3 not support 120hz?
dishonored 120 fullscreen ok
deus ex: hr 120 fullscreen ok.


so can I assume as a general rule of thumb, windowed mode does not like 120 and will not (if never) work?
not every game will run on 120? (like diablo3?)

Now that you mention secondary display, since I am using the 660ti HDMI output for Audio on my HK receiver..that is detected as another display...I wonder how if anything, that really affects my performance.
Heck, I changed the Resolution to the smallest for that one just in case. biggrin.gif

I could be wrong, but I THINK windowed mode would still work at 120Hz as long as NO PART of the window is touching your second screen running at 60Hz.

I've seen some "windowed fullscreen" settings actually extend a few pixels onto my second monitor, thus reducing the refresh rate to 60.

As for games supporting 120Hz, you can usually force them if you choose the "Preferred Refresh Rate: Use Highest Available" setting for that game in the Nvidia Control Panel. It works with a lot of games that do not include a GUI refresh rate setting, but it does not work with all games

Vsync Off will not limit your frames to your monitors refresh rate, so you could see fps way higher than 120.

you`re right, some games seem to extend pixels to the second screen which is causing this.

i dont see this Preferred Refresh Rate setting in my NV CP, but I set it in NV inspector though.

In the Nvidia Control Panel, under the Manage 3D Settings section, Program Settings tab, you can select the refresh rate for specific programs that otherwise wouldn't let you change it.

This is useful if you wanted to run 96Hz on the desktop, but wanted to run games at 120Hz, and the game has no option to set its own refresh rate

Can I run 1920x1080 @ 120hz on my Qnix without having my screen centered in the middle with black boarders? 60hz @ 1920x1080 works fine, I get stretched full screen, looks ugly as hell tho, but before my new graphics card gets here I want to play bf3 @ 1920x1080 @ 120hz without my screen centered in the middle surrounded by black boarders. Any one got solution to my problem? Please help.

Btw when I got to CCC when its 120hz the scale image to full screen doesn't work and overscan is grey out too...

i wonder will this screen work on the new 290x

It will, and you should be able to run 2 of the DVI-D only versions off a single card too thumb.gif
