My Roku Premier was due for an upgrade. It passed HDR flawlessly at 60fps and was astonishing to behold. But it wouldn't do Dolby Vision because Premier didn't.
So I got the Ultra LT and used the same input. Dolby Vision shows up fine, but Ultra says that the TV Premier was delivering fine HDR10 to wouldn't accept HDR.
I figured perhaps it was the Yamaha AVR so I switched the HDMI coming from the Ultra LT from the receiver to every HDMI input on the TV itself. Still, no HDR.
The only other thing I am noticing is that it now looks like all content is HDR, with popping brightness. Colors seem natural. HDR movies play watchably, though some 4K looks a little stutters. The Bravia Picture settings indicate Dolby Vision is always on. (I can choose Bright, Dark, or Vivid, but not Off).
My library is filled with HDR titles. Wondering if I need to replace them with DV versions. Or perhaps the included HDMI cable isn't up to the task.
Suggestions appreciated! Should I drop the Ultra LT and get the Streaming Stick 4K+ instead?
