Most likely your LCD isn't supporting 1920x1080 and you can't change the resolution without any display so you can simply do this : After powering on the computer, quickly repeatedly press F8 to go to the 'Advanced startup options', then select "Enable low resolution video (640 × 480)" and then set your resolution accordingly.
