We asked TiVo about the problems as part of our usual review process. A representative said in a phone interview that the black-screen issue is caused by a 4K TV and streamer together negotiating the incorrect HDR mode (). The company expects to release the update at the end of June. The update will automatically select the HDR version as well as enable users to turn off the "always on" HDR effect.
TiVo's rep suggested that as a temporary fix users should choose HDR10 by default from the Stream's settings menu (Settings> Device Preferences>More> Screen Resolution> HDR10). TiVo also suggested users install Google's latest Android TV updates in the Play Store. We applied the HDR10 fix and found it worked on the Sony X950G, but not on the LG CX.
TiVo's late June update is not the first major fix the company is applying to the device. On the night of June 5 an update rolled out to address two more issues: a black screen that appeared when switching between the Stream app and the home screen (we experienced this only once) and something TiVo called Ghost TV, where the HDMI CEC function on would randomly power on or switch inputs on a connected TV.
The Stream 4K has performed well on other TVs in the review process, including an older HD plasma model. Look for a full CNET review once the latest update becomes available.
