I found that it wont go to the input with discretes unless there is an active source feeding it
I could be wrong but was testing one in the office and didnt find discretes easily until I plugged in a tester (thanks Brent) and then it would allow me to select it
I am still looking for HDMI 3 for a FP-T5884 Plasma or something like that
There's no worse feeling than that millisecond you're sure you are going to die after leaning your chair back a little too far.
