New Input button on Universal Smartglass Remote does *NOT WORK* for Yamaha RX-V575 Receiver!

I was looking through the online manuals for both your Yamaha receiver and your Samsung TV, and I think I found the problem.

Your Yamaha RX-V575 does not support 4K@60Hz, according to the HDMI specs in
this page of the RX-V575 manual. It is only compatible with 4K@24/25/30Hz, which seems to be why the Xbox is not properly displaying 4K while connected
to the Yamaha receiver.

I suggest you plug the Xbox directly into the TV's HDMI port, and use an optical cable from the Xbox to the Yamaha receiver if you have a sound system set up.

You nailed it. The Yamaha pass through was the issue. Hooked it up as you suggested and BAM! Apparently some Netflix content is broadcast in 4K at under 60hz, which I could receive and view. That led me to believe that all 4k content should be viewable.
Not true obviously.. I was not getting anything in 4K@60Hz - which is a LOT I see. Yamaha users be advised......check your specs.

I have the rx371 and it works great, you won't notice a difference as long as you keep your tv on the game input

Hi Studbucket33, I've having similar lack of control problems for a Yamaha RX-V800 receiver. Do you have any alternate remote codes I could try? The one it gives is R0082.

May 2014 Update didn't fix this. Hoping maybe the June update will since it will have the universal remote on Smartglass
