HTPC w/ GMA video>HDMI>Denon Receiver>HDMI>Pioneer Elite TV

I have a PC hooked to a Denon receiver via HDMI and then on to a pioneer elite television.

The PC is @ 1080 resolution. If I power off the Pioneer TV the resolution on the PC gets knocked back to 480.

Is there a way to force 1080 from the GMA video card regardless of what the Denon is telling it, or a DVI Doctor type device for HDMI that will keep the PC at 1080p regardless of the power state of the TV?

I have an onkyo receiver in a similar setup that does not do this when the TV is powered off.

This could be a fallback "feature" of the Denon.

Question: how are you noticing the 480p situation, or is it not restoring itself to 1080 when you turn the TV back on? Also, to test, what happens if you hook the HTPC directly to the TV?

Regardless, you should be able to stop this behavior by changing the monitor driver from Plug 'n' Play to something generic, or disabling DCC detection... some drivers also allow you to force specific resolutions (I don't know if Intel does).
