Yo I just bought a Roku Ultra for my 2K HDR TV and it refuses to do anything but 1080P with no HDR. Even worse, it doesn't even detect HDCP 2.0. What the **bleep**? I just wasted $120 on this. Any reasonable device would downscale 4K and use HDR but apparently that's too much for Roku. I been using Roku for years but **bleep** y'all after this
