Just recently whenever I start the game I get a black screen, I can clearly see the game screen if I hover my mouse over the games tab in the taskbar on my 2nd monitor and it appears to have loaded up as normal as I can also hear the music. However my main monitor stays black, I have run in 32 and 64 bit, checked integrity of game files and even completely uninstalled and reinstalled the game but still the black screen, I have also installed the latest drivers and tried rolling back to older drivers. Any ideas as I am at a loss as to what might be causing this.
Quick update on this, opened up the graphics settings file and it shows 144Hz as refresh rate but for some reason my monitor is set at 120Hz in nvidia CP and will not let me change it to 144. So changed 144 to 120 in graphics setting file, saved It, and hey presto the game works fine. Just need to find out why all of a sudden I cant change the refresh rate on my monitor.
