Why is the image not in HDR or the picture quality poor when watching HDR content?
When you specifically watch an HDR movie or TV show on your HDR-capable Roku device, you may notice the image is not displayed in HDR, or the picture quality is poor. If you encounter this behavior, you may need to update the software on your HDR-capable TV. You can typically find instructions how to do this along with the latest software on the TV manufacturer’s website. Once you confirm that your TV is running the latest software, check that it is properly configured to enable HDR on the specific input to which your Roku player is connected. Some TVs that support HDR do not enable this feature by default.
