I just bought a Samsung UHD TV (UE58MU6120) and was pondering upgrading my receiver. Having used the TV for a bit I realise there is no need. It has three HDMI inputs one of which is ARC enabled and is connected to HDMI out on my Onkyo. I have a computer, which is almost redundant because of the apps on the Samsung, also connected via HDMI to the TV. I could have a Blu-ray player attached too but I have a Blu-ray drive in the PC. You could connect an Xbox or whatever. The point is the TV outputs sound to the receiver in whatever format the media are in and the receiver faithfully displays the format and amplifies it to 5 speakers. I can't see I would gain anything by shoving everything through a UHD enabled receiver. I'm satisfied anyway.
