GTX 680 not giving me full screen resolution. Tonelabs sleep won't work. SOLVED

Hi all,

I just got a new 1080p 39" samsung:

Unfortunately, Mountain Lion is not letting me utilize the whole screen when I set to 1080p in "Displays". If I uncheck "Scaled" it then makes things too big, if that makes sense, and things are off the screen and only half visible.

Here is my current plist file within Mountain Lion

<?xml version="1.0" encoding="UTF-8"?>

<string>Yes</string>
<key>Timeout</key>
<string>2</string>
<key>UseKernelCache</key>
<string>No</string>
</dict>
</plist>



Also, I tried tonelab's sleep kext and it is not working:

I don't think you need npci=0x3000 and PCIRootUID=0, do you? Also cpus=12 seems odd. Please try without these and see if that works.

If you're unsure about those then I am not going to change them because I fear a panic and am currently in the middle of an important project.. cpus=12 was given to me in tonymac chat support, in order to utilize all 12 cores.

I'm trying to help. Also, removing those flags does not commonly give you a kernel panic, do your study. Even if you DO get one, you can boot safe mode [-x] and/or enter the needed boot flag.

I tried it, I'm still having this problem.

Thank you, still can't solve this resolution issue though.

I tried removing PCIRootUID=0 npci=0x3000 cpus=12 and setting UseKernelCache to YES but it caused my screen to go black after apple screen, so I had to boot with PCIRootUID=0 npci=0x3000 cpus=12 UseKernelCache=No
