Last night I was running a 1920x1080 and everything was fine then apartently a driver for r9 380 4gb tried to update and failed. I reran the update went fine but the 1920x1080 resoultion is gone. I tried unstalling and reinstalling the driver. but still the same thing. any Ideas?
Sometimes the refresh rate gets changed to 59hz.with a new driver installation. Change it to 60hz. Somehow this makes a difference..don't ask me how...and the missing resolutions magically return...for some people.
