I have a System76 Wild Dog Performance with an NVidia GeForce GTX 560 Ti. I'm trying to figure out how I can make fullscreen apps (games) maintain proper aspect ratio. I'm using a monitor with 1920x1080 resolution (16:9), and some games appear stretched because they are for example 1024x768 (4:3). What I would like is to have black bars on the sides of the game so that the aspect ratio is maintained.
I'm using Ubuntu 12.04 64-bit. I tried looking in NVIDIA X Server Settings but can't find anything? If anyone can help, it would be greatly appreciated.
