Graphics only. My internet connection is fine.


When you are in the control panel on screen resolution, the maximal value that you can choose is 1600 x 1200, and it says above that the screen is non plug-and-play generic on a video card VGA standard.


Due to this, the Windows performance index is determined as 1.0 (the minimal value). I cannot have the "Aero" look of the Win 7 windows either.


I did not have such problems with my old iMac 9,1

After I read other discussions on the same topic, I found out that the problem is that when you install the drivers via the Bootcamp "windows support software" USB key, for some reason the NVIDIA drivers are not installed, although they are present in the Bootcamp folder.


How I solved the issue: Starting from the Peripherals Manager window (the one that shows all what is inside your machine), I opened the Graphic card "folder" and double-clicked on the "VGA standard card" line.

Then I clicked on a "install driver" button, browse through files, and selected the NVIDIA folder within the Bootcamp folder on the USB key.


It took some time but after that it had fully recognized the GTX 680 MX card.


I rebooted and the system itself set up to the 2560 x 1440 resolution.
