Hi. I have tried calling the manufacturer, and searching this and other forums, but have had no luck at all.

I have tried everything - hooking up HDMI cable with everything powered down, adjusting the monitor settings on the Elite monitor to accept PC over the HDMI input, adjusting the laptop so the AVR is a duplicate monitor. The laptop sees the Pioneer AVR correctly. I get no sound and no picture no matter what I do. The AVR doesn't seem to recognize that there is an HDMI cable connected to the HDMI input. The display window on the AVR just reads "stereo", just as it does with no HDMI cable connected. Yet if I remove the cable, my computer recognizes that the HDMI connection and AVR were removed. The laptop does seem to adjust the display when connected to either the monitor or the AVR. I tried direct connection from the laptop to the monitor with similar results (of course, no sound expected from this monitor-only plasma TV). I tested my HDMI cable with another system and it seems fine.
What am I missing here?
