I just upgraded from a Roku 3 to Ultra. It is directly connected to a current gen Sony OLED, 65" A8G. I'm having a couple of issues with the Ultra:
1. If the Auto adjust display refresh rate option is enabled, I get HDCP errors every time the content changes, e.g every commercial, even though the refresh rate isn't changing. Not a huge deal, but I was hoping that I could send 24p content to my TV which I think should be better at motion interpolation.
2. Most SDR content looks dreadful. Color is over-saturated, there is a mild red push overall giving faces a pink tint, and pure reds are blown out into neon territory. There is also (IMHO) excessive sharpening and brightness/contrast enhancement. It looks like somebody switched my TV back into showroom mode. I suspected it was an overblown SDR to HDR conversion, but the same basic problems can be seen if I change the display type to 1080p TV.
Other sources are ShieldTV, Oppo 103, Panasonic UB820, and the TV's apps. The Roku and Panny are directly connected to the TV while the Oppo and Shield go through my Marantz 8801 (thus limited to HDMI 1.4). The Oppo, Shield, and Panny look great with SDR sources. The Roku and TV's apps are unwatchable. The difference is much smaller with 4K HDR content, where they all look good.
Any idea how I can resolve this? Am I missing a setting?
