How can I attain Full Resolution on 1920X1080 Monitor using GTX680 on 10.6/10.7

1 post in this topic

Recommended Posts

I have 3 Mac partitions: 10.6.8, 10.7.4, and 10.8.3. I was able to display everything at full resolution on 10.6.8 and 10.7.4 with my GTX680 on my 1360X768 monitor via

Graphics Mode=1360x768x32

flag with Graphics Enabler disabled in my Boot.plist. I upgraded to a 1920X1080 monitor and now I have an ugly black border around the screen during the bootloader, 10.6.8, and 10.7.4. Example shown below:

I have been sifting through past posts and other articles that have addressed remedies towards this issue such as the following:

 

Link 1 (This method didn't work by the way)

Link 2 (This method is for AMD GPUs)

Link 3 (I have yet to try this)

Link 4 (I have yet to try this)

 

Editing the BIOS of the GPU seemed about the only promising method I seen available but I am apprehensive about it because it could accidentally brick my GTX680. I wanted to get the opinion of members who have experienced this problem and to find out whether any of these options I have listed you would suggest or should you have some options of your own that you would recommend to me as well. Any feedback is greatly appreciated. Thanks in advance.S/N: 10.8.3 boots fine in native resolution
