Windows 7: Problem with pc blinking monitor (off/on) when TV changes channel

Problem with pc blinking monitor (off/on) when TV changes channel

Here is the situation; when the pc is being used at the same time the TV is on and the channel is changed the pc monitor goes blank (off) for a 1/2 second or so and then turns back on. This happens every time the TV channel is changed.

My setup and equipment:
Computer: Gateway FX6831 with Win 7 64-bit service Pac 1, 12 Meg ram, ATI Radeon HD 5850 graphics card with 1024 mbytes ram. Intel I7 860 processor, Intel 120 gig SSD.
Monitor (pc): Acer H233H 60 htz. @ 1920X1080
AV Receiver: Onyko TX-NR708, with HDMI with inputs and one output to TV.
TV Panasonic TCP54G25, plasma, 2010 model with internet abilities.
HD DVR cable box

The connection is as follows: HDMI cable out from pc (ATI graphics out) to AV receiver HDMI in. Then AV receiver HDMI out to TV HDMI in. The AV receiver remote is used to select "PC" to display the pc on the TV monitor.

This setup works great. I have a separate cordless mouse and keyboard to run the pc when I am using the TV to access the pc from another room. The problem being the "blinking" when a channel is changed on the TV. There are two HDMI outputs on the ATI card and both do the same thing.
