I have my Raspberry Pi hooked up to an old Philips HD ready FlatTV. I have my XBOX360 working over the HDMI -> DVI cable, and it is using these settings:
1280x720 Breedbeeld (Widescreen) DVI+A
I have been fiddling now with the
config.txt file with mixed results, but none of them seem to really work. The best I have got now is this setting:
hdmi_group=2 hdmi_mode=0x55 hdmi_drive=2
With these settings, I get some text-mode bootup messages, but once the Pi is booted, the screen stays blank.
