I've just got a Panasonic X60B Plasma TV (720P or to be precise 1024x768) to use with my RPi instead of my LCD monitor.
I was rather confused at first as I couldn't get any sound out of it and checked I got sound with my Xbox360 and tried swapping the HDMI lead but eventually I fixed it by commenting out these lines from config.txt, which I'd added before to force it to run at 720P:
#hdmi_ignore_edid=0xa5000080
#hdmi_group=2^M
#hdmi_mode=85^M
So now it works but it defaults to 1280x720@50hz and if I change it to 60hz, it also changes the resolution to 1366x768@60hz, with the hz greyed out, so is there any way to force it to 1280x720@60hz?
Does this setting just control the GUI anyway and will video content output at the correct refresh rate (the TV can run at both 50hz and 60hz and it's obviously desirable to have it match the source speed)? 1024x768 and 1920x1080p are options as well and I'm pretty sure when I was testing them, 1024x768 made it quite a bit brighter for some reason but I'll double check that again later.
