HDMI resolution resets when Xbox is turned off

Every time I turn off my Xbox 360 after playing, when I go to turn it on again I get "Unsupported Mode" on my TV. The Xbox is connected through an HDMI (I also use this HDMI for my PS3, and it doesn't have any resolution changing issues). If I power down the system, then hold down on the power button until the resolution resets to 480, I can go in and manually reset the resolution in settings, but I don't want to have to do this every time, and I didn't have to do this before. Is there a way to fix this?
