I've been using an Asus O!Play without issue to play videos from my WHS on my projector. HDMI was from the O!Play, HDMI Switch (monoproce), V663 Receiver, Projector (Optomo HD71). This works without issue - the projector is 720p, but downconverts a 1080p signal without issue.
Recently I put together some old computer parts (EVGA680 SLI/Core2 Duo/Sapphire HD4350 ) to test out a HTPC setup, and my issues began.
With the HD4350 HDMI output -> switch -> projector I have no problems with 720p or 1080p resolution.
With HD4350 HDMI output -> projector no problems with 720/1080
As soon as I throw the receiver in the mix (Yamaha RX-V663) - with or without the HDMI switch - I have resolution issues. With 1920x1080 as the output resolution on the computer the projector indicates it is trying to operate on a 2401x540 mode. With the computer output set to 1280x720 the projector indicates it is in a 1563x360 mode. The screen is displaying artifacts which I can identify as my computer desktop, but with obvious color/alignment/noise.
I've tried different orders of powering up the receiver/htpc/projector to eliminate HDMI handshake issues, but to no avail. Audio is being carried properly over the HDMI connection regardless of the video setting, and so I'm not sure what this means with respect to a handshake issue (is there a separate negotiation for video/audio - or if one works should the other?).
Currently I have the DVI output of the video card going directly to the projector, the video card set to clone mode, and the HDMI (carrying the audio) going to the receiver. This works, but it really bugs me (as well as forcing me to run an extra cable up the wall to the projector).
Is this likely something that a different model video card would rectify? Are there any other discrete video cards which would allow me to pass through both audio and video? Not really looking to replace the receiver at this point, as I'm happy with it otherwise, but a new video card would certainly be in the cards.
I didn't find the right solution from the internet.
