Okay so I just bought my self a brand new monitor that is 16:9 and is hooked up through HDMI. My old monitor was a 4:5 and was hooked up with DVI. Since I have been using my new monitor Skyrim went from 45-50 FPS to a whopping 2-3 FPS. However when I either switch back to the 4:5 Monitor or have both of them plugged up at the same time, the game runs fine. I am not sure what might be the cause of this, and I cannot find any solutions online. Specs: Windows 7 Home Edition 64-bit Intel i3 3.30 ghz dual-core 6GB RAM GeForce GT 640 2GB I can run Skyrim on ultra graphics with HD texture mods on the 4:5, but the 16:9 can't even run vanilla Skyrim on low graphics. If anyone has a sulution or any knowledge of this please respond.
