I'm having an issue when XBMC is starting, it may be similar to the issue described in this post HOWTO: fix HDMI resolution problems when your openelec box was turned on while the TV was off but it is a little different - I have a signal for the display and then it is lost regardless of when I turn on the TV.

When I boot up my ASRock Ion 330, I see the OpenELEC splash screen, but when that disappears, my old Vizio TV goes blank for a moment, like it has lost its input, and displays a blue screen that appears when there is no current input device turned on. Sometimes, the display "snaps" back into place and shows XBMC, sometimes is gets stuck on the blue screen and I have to go do the HDMI 2 input, then go back to HDMI 1 to see XBMC.

Is there anything I can try to keep the display from cutting out during start up?
