Samsung QN90A - Xbox Series X random Black out

[Fletch78]

My Xbox series X randomly displays black screen for 1-3 seconds in game when setting to 120FPS, ive seen lots of post about this issue with Samsung TV's but not any with a fix. i have logged a call with Samsung but they just checked the software version and advised on using the correct port and cable, has anyone resolved this issue?

So I have game mode on. I've plugged it in port 4. I've hard reset it, changed resolutions, and nothing has happened it's stayed the same. I still get a black screen when going into the same so it's just stuck unless I turn hdr of

Did this “fix” work for you? I’m using a 3090 strix and this is happening

I have a qn95b tv and had the same issue with a Series S.  I changed the cable, fiddled around with a number of settings but since I turned off VRR it appears to have worked.   Strange as reading through the responses there is not a single solution that works for all but try this if still struggling.
