A:Answer HDR cannot be manually turned off. If the content you are watching supports HDR, HDR will automatically enable. For other settings, you can access the Options menu on the TV by pressing the asterisk (*) button on your remote while watching content. Additionally, you can access expert picture settings by downloading the free Roku mobile app on a smartphone or tablet. The Roku mobile app works as a remote and allows you to access additional features like voice search, private listening, expert picture settings, and more. Hope this helps! Thank you, TCL Customer Support
