Is Samsung ever going to fix this issue? I have Q6FN 65" tv. I read some other articles related to the same issue. When in the middle of a game screen will go black with a loading circle spinning in the middle and it will say 'game mode off' then say 'game mode on'. It happened on my PS4 slim and then on PS4 pro it's been happening too. I also tried different hdmi cables but nothing works. I have no idea why Samsung can't fix this. Some of the articles related to this issue I read are more than a year old. It's so frustrating.
Same issue here with PS5 + Samsung Q90T 75". Booked a repair with Samsung to see if a technician can fix it, but if he can't the tv will be going back for a refund. Impossible to game when the screen will go black randomly at any moment!
I am having the same issue with my Q65 and PS4. Changed cables, turned off and in game mode, changed resolutions on tv and PS4. Nothing works. Fix this issue Samsung!!! I see articles on this same issue going back two years and all I see from Samsung is “try a different cable”.
