Advertisements So is SDR really one of the things the TiVo Stream 4K can't do? I got mine setup a short time ago. At least the setup process wasn't too bad. And the Firmware install only took 3.5 minutes from when it started downloading to the time the menu came up after rebooting. But mine seems to always want to send out HDR. Either HDR10 or DOlby Vision. I see no way to send out SDR. Or am I missing something? That was was the reason I didn't use my ATV 4K initially until they patched it to allow it to properly switch between SDR, HDR10, and DOlby Vision. Or am I missing a setting? Because a normal device will automatically switch between SDR, HDR10, and Dolby Vision as needed. I have no desire to watch HDR10 content in Dolby Vision or SDR content in Dolby Vision.
