A few days ago I downloaded the latest TDM. Today I downloaded 3 missions and I went straight to the video settings and set the screen to 1920x1080 -(I should have chosen 1920x1200 but my monitor does both) The screen stopped and I got a "no video input" message which is my ACER monitor's default message for not connected. CTR ALT DEL would not get me a screen back so I had to turn off power and let it reboot. Everything is good. But, if I run TDM the same thing happens after I click TDM I immediately get the "no video input" message again and the screen loses all touch with the system. I have to switch off power and turn on again -it reboots fine. I looked in all the files (in TDM folder) that had today's date on them but could not find a reference to resolution. I'm working with: Windows 7.1 64bit Acer X263W 1920x1200 (recommended res. to use). Gforce GT 430 6GB ram Intel core2 quad 2.50ghz cpu I want to be able to get back to changing the res for TDM but cannot as I lose the video.... any suggestions?
