First I tried changing the resolution in the xbox settings - to 1080p or 720p - but changing the resolution made a message pop up on the monitor saying out of range.I tried using a different DP cable, power cyclling the xbox and the monitor, messing around in the monitor's settings,. but nothing changed. I need help in making the Xbox output a 1080p image. Any help is appreciated.
I didn't find the right solution from the internet.
