I'm running HDMI video and audio from the on-board ATI graphics output of a GIGABYTE GA-MA78GM-S2HP motherboard to an Philips TV. It works fine, but every once in a while the screen will go blank and I can't seem to get it back without reseting the computer. The screen saver and power modes don't seem to cause it and I tried disabling them to no avail.
Does anyone have any tips on how I could (a) reset the video output without a hard CPU reset, (b) gather more data to troubleshoot the problem and/or better yet (c) know what could be causing this issue?
I have replaced the 19" TV with a 24" HDMI monitor and have not had a reoccurrence of this problem since that time.
