Get a good sleep.":O}

Get some rest I'm in good shape until the morrow. I downloaded the file first

I followed what I thought you wanted but am not getting the results expected. I offer these to show what I have done and the response.

To be honest I'm a bit lost here.

In the meantime...

I switched HDMI 1 to my roku last night. All my troubles with UHD went away. So it's definitely the receiver in the loop that prevents proper recondition of the 2.2 cable standard. With the receiver in the loop Roku fails every thing above 1080. It then lets me force it, but that only gives me 1080

Is why I was asking about the lip sync problem when using the hisence as switcher.

Not to worry K. You've been more than generous with you time.

What time are you most available for this...I think we may have missed each other this go around?
Now 10 15 my time, it's dark out so I'm guessing night time.

Where did I go wrong?

I have ended up with several copies, do I need them, does mint need them thinned?

ok I have gotten a good reboot, everything looks good., putting reciver back into the loop.

Receiver back in the loop.

Everything went to shit my friend. Computer boots to a green screen. I'm use to that occasionally, but it's not straightening out by the time it reaches my computer screen, now it stays green. REz back to 1920X1080

Roku has gone back to failing everything above 1080, I have to force it again.it says it fails to pass 2.2, yet it does pass when only the Roku is connected.

All this goes away when using the TV as the switcher. BUT when using the TV I could not get sound to sync

I'm just looking for the easiest way to go. entirerly up to you K.
You have to do thre brain work here ":O}

PS still no sound. I'm beginning to think this is not a match made in heaven":O}
PS I'm certain I choose binary for the EDID, but can't check as it's now Denon rather than Hi sense.
As switching inputs returns the Green, it 's probably not the loose input plug.
