I've seen this happen to too many "receivers" and swapping in another model receiver usually clears it up. Or bypassing the receiver. Test your way to where the trouble is.
I bought a Win8 laptop for the sole purpose of using it as dedicated machine for my TV.
The HDMI ports connects to my audio-reciever, which is then connected to my TV via HDMI as well.
Usually, the laptop recognizes the connection, and displays the desktop on the TV.
Too often, that connect is not recognized, and have to turn on/off the TV and receiver in an effort to establish that connection. Once I get into that game, it either works right away or not at all. If that connection is not established, then here is no telling what it will decide to connect again.
I have updated the DisplayLink drivers hoping that would do something. It did not, and I uninstalled it.
This is so frustrating. What are my options here?
