Correcting HDMI Handshaking Issues with Windows Media Center and Onkyo Receivers
I don’t know if anyone else has experienced this annoyance, but whenever I switch to the input on my Onkyo receiver (TX-SR607) associated with my HTPC and Windows Media Center is already running, the resolution and aspect ratio get fouled up. Everything is much larger than I want it to be and TV playback from my Ceton Infinitv4 does not work. Previously, the only fix was to close Media Center and open it back up. I needed a cleaner solution.
– Turn off HTPC. Shut it down and leave it turned off.
– Go to the input on the Onkyo for your HTPC
– Press the Receiver button then the Video button on the Onkyo Remote,
– Change Resolution to Through (this will pass signal as is from HTPC to TV)
– Turn back on HTPC
Now the resolution and aspect ratio are correct when you switch to this input and WMC is running.
