There's a potential workaround for the Xbox One TV integration judder issue.
HDTVTest, which spotted the problem with UK Xbox One's earlier this week, disovered a way to force the Xbox One to output a 50Hz signal - matching the TV signal pumped into the console through the HDMI-in port.
As the site explains, to do this you need to set your Xbox One to auto-detect HDMI from within the display settings, then toggle the resolution from 1080p to 720p or vice versa. This triggers a prompt asking if you'd like to keep the new resolution. Select no.
Apparently this tricks the Xbox One into thinking your TV isn't compatible with a 60Hz signal and forces a 50Hz output.
Unfortunately, this workaround isn't ideal. It makes everything 50Hz, including video games. So there may be stutter when playing games. You can of course manually switch back to 60Hz to play games.
Microsoft is yet to comment on the issue.
