This is how you fix your resolution Even for those who go into the config file and change resolution with no result. Try this Delete the config file -Documents, DayZ, DayZ {With CFG file ext.) DELETE. dont worry every time you start the game it will recreate this file. Restart the game Your shitty resolution should still appear. Close Game Go into the recreated DayZ CFG file. The shitty resolution specs should now properly appear. Change them to your monitors native display resolution ..i.e 1920 1080 Restart DayZ Should be g2g
