Hey guys I found out the fix. Go to configure>Video>User Interface>Resolution and set your resolution to 1366x768x32. If you changed to windowed through dayz.cfg you have to change it back. I hope this helped.
Hey guys, I have the same problem. I changed the numbers in the DayZ.cfg and that didn't work. I also tried all the aspect ratios and none of them helped. It works in windowed mode and I am on a laptop. Could that make a difference? Please help!
