Why is the image not displayed in HDR or the picture quality
poor when I watch 4K HDR content?
When you specifically watch a 4K 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.
