HDMI woes - Problem with detecting my TV via receiver
I have an HTPC with onboard HDMI (It's an Ivy Bridge processor on an Asrock Mini-ITX mobo). I have the HDMI output from HTPC going into my Yamaha RX-V375 receiver, and I then have the receiver HDMI output going into my Panasonic PNF5300 plasma TV.
When I first connected things up, everything worked well. My HTPC detected the TV as a Samsung Digital TV and had all the supported resolutions and refresh rates including 24pHz which I can then use with Cinema Smooth for 96Hz playback on the TV. This also worked well with MadVR and MPC-HC where I could force the 24p refresh rate during playback of 24p content.
The problem seems to arise when the HTPC is still on and I turn off the receiver and TV. Sometimes, when I turn the receiver and TV back on, the Intel drivers now report my display as a Yamaha Receiver and does not "see" my Samsung TV. As a result, I only have 60Hz refresh rates available and cannot make use of 24p playback.
I'm guessing this is an HDMI issue with EDID, autodetect, etc, but I really have no idea how to fix this. Plugging and unplugging the HDMI cable doesn't help as it still shows up as a Yamaha recevier. Rebooting did not help either. At the moment, I've had luck connecting to the 2nd HDMI port on the TV at which point my HTPC again detected the Samsung TV as the display device.
I'm afraid that turning off the receiver and turning it back on will create this issue on the other port as well, at which point I won't be able to use 24p mode on my TV. Does anyone have any suggestions/thoughts on what I could do to try to fix the issue? Is there a way to hardcode the EDID that Windows sees, so this doesn't occur? I'd prefer not to have my receiver turned on 24x7 just to avoid this issue.
