I'm having an issue when connecting my Mini to my Samsung TV when running it through a receiver (Pioneer). Before we had the receiver in the mix, this issue never came around. Now that the receiver is involved, I believe this may be an issue related to the "handshake" that I've been reading about when HDMI devices try to connect to eachother.
- If I sit down on the living room couch, turn on the TV, receiver, and Mini, there are no issues. The resolution is correct.
- If I leave the TV off, receiver on, boot up the mini, and connect to it via OSX Screen Sharing... I am able to use it as a media center and play music through the mini and receiver, leaving the TV off to save power.
What doesn't work:
If I try to switch between "living room" mode (couch / TV) and "Screen Sharing" mode, the resolution gets all fouled up and I need to reboot the mini in order to make it usable. Here is a screenshot showing how it looks when trying to go from "living room" mode to "Screen Sharing" mode:
The only way to get out of here is to hold down the power button, forcing the mini to shut off abruptly, then reboot.
Conversely, if I try to switch from "Screen Sharing" mode to "living room" mode, it's a little different - the top and bottom of the screen is cut off. Part of the dock is off of the screen, and the menu at the top of the screen is virtually gone. With this method, I'm actually able to move the mouse off the screen and navigate to "Apple -> Restart" so that it reboots and starts working fine again.
I've been on the phone with Apple (yes, I have Apple Care) and they pointed me to Pioneer, saying that the mini was receiving instruction from the receiver. When I called Pioneer, they had me turn off some "HDMI auto detect" features in the receiver but this did not resolve my problem.
Any suggestions? Any help would be much appreciated!
