Netflix 4K and HDR not Working. It's either HDR or 4K not Both.


RokuUltra 4660X02

TV: Samsung: UN60KU630DF

Receiver: Onkyo tx-nr 656


Can't get them to work at the same time. 


Auto set-up detects HDCP 2.2, 4K 60HZ HDR compatibility. 

TV is set to Full UHD Color HDMI 1 for HDR premium. 

VUDU Works with HDR and 4K no problem. 


This is only with Netflix. It's either or for my parents house. Trying to get them updated, but this is the only issue I'm having with this Roku. 


Please help me. I'm at a loss. Netflix is the thing they use the most. If leave this setting as is, they don't get 4K on Netflix only HDR. I can't have them changing the setting every single time they want to watch Netflix in 4K. They shouldn't have to choose.

Re: Netflix 4K and HDR not Working. It's either HDR or 4K not Both.

I have the same issue with two different T
setup and 2 Roku ULTRA 4660X with Netflix where I either select 4K or HDR and both setup are compatible with 4K HDR 30Hz or 60Hz. It is clearly a bug in the Netflix Roku app. Can someone from ROKU fix this?

thank you
