I know that a few 360 games require the TV to be set to 60Hz in to play - The Outfit being one of them. I downloaded the demo, and when I tried to launch it I was told that I had to be set to PAL-60 not PAL-50, and to change it under the Display settings. However I'm locked out of the screen format setting because it says they're done automatically with the HD AV cable plugged in. So, I can't change the settings.
I also can't change the settings on the TV itself ( an Acer AL2671W), even though I know it's capable of at least 60 Hz, having used it as a PC monitor at both 60 and 75. It seems that both the 360 and the TV rely on getting their refresh rate settings from whatever's connected to them, so I don't see how I can change it.
Any ideas?
