How to change my monitor display from PAL-50 to PAL-60?
Solution 1:
This is a setting on the Xbox itself, no the TV/monitor, however, as seen in various places, the setting isn't accessible on the Xbox when connecting by HDMI.
What you need to do is get your standard Xbox display cable, connect it to a TV and make sure the switch on the cable is set to TV, after that the setting to display on PAL 60hz will be available, once you set it you can go back to your HDMI cable.
