Hi, guys! When I went through the installation setup procedure, I selected the resolution mode to 2.0 GB, I feel that the resolution mode 2.0 GB is pushing it because I have the GTX 550ti 2.0 GB graphics card and I already have the Saab 340A installed, so how do I select the resolution mode from 2.0 GB to 1.5 GB? Thanks! Cheers, Vincent
