How to turn off HDR on Roku Smart TV?
Philips 50" Roku smart TV model 50PUL6533/F7.
As Charles and the other customers here have stated there are no options for turning off the HDR picture on the secret menu (home 5xs, etc.) or in the TVs system settings. It's just not available. Also, as someone else mentioned, the 4K & regular HD picture settings are more than fine. There needs to be a fix here. If Roku was able to remove this feature from the secret menu then you should be able to put it back. The HDR feature kills the picture making it dark and dull especially when compared to the reg HD picture settings when not in HDR mode. Also there's no way to adjust/override this manually using the advanced picture settings. I've spent more time than I know trying.
I've been a loyal Roku customer going back to the Roku 1 box that connected via rca cables, as most TVs didn't have HDMI at that time. The product and customer service has always been good if not great. Obviously this seems to no longer be the case. All we are asking for is the option of shutting off the HDR. If it was removed in an update then it should be able to be uploaded in another update. What's the point of owning a Roku TV if you can't see the picture? Especially as more series, movies etc are in 4K. I've included pics of both menus so you can see our lack of options for HDR settings.
