I have slingbox component cables plugged into the Directv Receiver which attaches to the TV by Component.
I also have a HDMI cable plugged into the Directv Receiver which also attaches to the TV by HDMI.
With the setup as this I would assume that I would have to select which cable to use by selecting the TV source (component or HDMI)? Well, I don't. I can watch Slingbox remotely and also get the best picture using the HDMI cable.
How is it possible that the TV knows which cable I'm using for output from the Directv Receiver?
On the setup for the TV I selected HDMI as the source. I have a 3D TV which only accepts HDMI to view 3D content. A 3D source can't use component cables to view 3D TV.
