Following the recent March update the 50hz option for TV viewing while auto defaulting back to 60hz for other services was working great for a week. Now without warning everything remains at 50hz. The old workaround to switch between 50/60 doesn't even work and everything I do whether TV or games runs at 50hz. Even if I disable the 50hz option in the settings the only frequency I can run is 50hz? When changing resolution it will flip to 60hz for the 15 second warning but whether I accept or cancel it always flips back to 50hz.
This is really frustrating after believing the problem was addressed in the update. I've tried a full power off, resetting the tv settings but I'm stuck in 50hz.
While I need this for TV (as that stuck in 60hz would be more annoying), I do have to suffer minor quality issues in my games.
Is this a known issue? Any advise to resolve? I'm assuming a bug in the software?
