Help with BenQ XL2411Z Monitor

[lolnope]

I ordered this monitor off amazon, I installed it and used the Dual cable it came with. I plugged this dual into my GTX 770 and my monitor and powered it up, it worked fine. I'm currently on 60hz and i changed it to 144hz but something like this happened http://i.imgur.com/aOm41xl.jpg all over the dark areas of the screen even when i play etc... Anyone got a solution?

Change it back to 60hz and Download FURMARK and put resolution at 1080p with 4AA and run it if you see weird things poping up than that's artifacts from the GPU

Looks perfectly fine when I run it at 1920x1080 on 4x MSAA. dont know what the problem is ;/

Now switch to 144hz and try it again

Yes, that's the problem... red dots appear all over some dark areas.

I don't think your GPU can handle the refresh rate do you have the latest drivers and everything?
