Hi everone! I've just buyed my R9 270x and put it on my p8z68 board in the blue slot, collegated it to my cooler master bronze 750W PSU and turned on the pc. I've installed the drivers and all went ok, but when the sistem rebooted the screen was... resized! I've looked at the resolutions, but it was still at 1920*1080... I've tryed many configuration hz-res and I obtain full screen only with 1600*900, even if my samsung monitor is 1080p. Does anyone know why? Thank you all!
