Playback Issues - Audio/Video & Power

[cgood311]

I have a Samsung KS8500 TV with a Roku ultra fully updated and just recently after a full year of no issues my Roku when watching Netlfix and Amazon Prime just before an HDR video plays it flashes and plays very washed out color palette. I rebooted the Roku and uninstalled both apps and reinstalled and still have the same issue. I bought a new model Roku Premiere hoping this would fix the issue and it did not. The HDR content plays fine on the Native Samsung Netflix and Amazon Prime TV apps so this is clearly a Roku issue. Is there any fixes currently for this.

It's not Reboot, Uninstall, Reinstall. It's Uninstall, Reboot, Reinstall. The order matters. Don't know if that'll fix it, but you didn't really reinstall the apps if you did it in the order you said.

didnt fix it. The Roku Premier was brand new out of box and had the exact same issue.

I have a new Samsung Q9 and the ROKU will not process HDR properly to it.  The few times I got it to work, I noticed it forced the Samsung to change its gamma mode causing a washed out picture. I'm not sure about your model Samsung but the q9 has three different gamma modes under Expert picture settings. You can try to adjust them or just stick with non-HDR which causes less issues.  Not a problem with the TV, its something with the ROKU

Thanks for the note here. Sorry to hear about the issue you're seeing! A few more details will help us understand the issue you're experiencing a bit better. 

- To help clarify, you said this issue only recently started occurring? When did you first observe the issue? 
- Could you please provide more information about which model of Roku device you are using, and specific examples of content titles inside the particular channel that you experience the issue on? 
- In Settings>Display type, what option do you have selected? If you try selecting a specific 4K display option, does this make any difference? 
- Do you have the Roku connected directly to the TV, or is it connected through an audio/video receiver, etc.?
- Have you tried using different HDMI ports on the TV and/or cables to see if this clears up the issue? 
- If you haven't already, please provide the specific TV make/model you are using with your Roku device. 

With more information, we can continue assisting you and take a closer look. 

Thanks!
Tanner

Same exact issue on my Samsung KS8000. HDR is always dirty, dark and washed out on the roku. Across multiple apps too. Native apps always looks fine, in fact great in HDR. Like was said in this post, definitely a Roku issue not a TV issue. Looking at Amazon Fire stick because of this.

Any luck with the fire stick? I have the same model tv (KS8000)

Well I guess this is a thing, because I’m having the exact same problem with my Samsung KS8000 and Roku Streaming Stick+. All firmware is up to date as of December 1, 2019. Really hope someone has found a fix they can post. Thanks.
