I just found out that it's possible to play a UHD disc on a UHD player and have it send 1080p resolution to 1080p displays. Certainly there's no visual benefit for doing so, however there is an audible benefit as a lot of the newer movies are including Atmos only on the UHD disk.
My AVR is Atmos/UHD/HDMI 2.0 compatible, TV and Projector aren't, but I'm thinking about buying a UDP-203 and want to make sure there won't be any compatibility issues.
Are there others here who use a UDP-203 with an AVR that is Atmos/UHD/HDMI 2.0 compatible, hooked up to a 1080p display with HDMI 1.4? Any compatibility issues with the display, or the HDMI cord itself, since they're HDMI 1.4?
