I meant manually set to 2160p23 and do the unplug and plug trick
Maybe u should try disabling auto switching and set the resolution to 2160p 23 mhz manually
Guys, try unplug and plug hdmi right after framerate switch . I haven't seen any black screen after this even turned framerate switching on .
Fw 2.1.40 I do get occasionally black screen in menu but not in movie playback
Here's a fix I worked out Go to advanced settings -> developer options -> enable 23.976/59.XXX option Now set your resolution to 3840x2160 23p...
