First time poster here, I received my sf 8008 single tuner this week running open atv 6.2 it is connected via hdmi on a 2160 30 capable socket and I originally set the box resolution for this but the display kept cutting out so I set everything to auto and multi this has improved things a bit but the display still goes blank occasionally, on my zgemma h9s which was connected to the same tv I just set the video to 2160 30 and had no problems.

I have tried 2 hdmi cables with no difference

Can anyone advise me on the best video settings

Many Thanks
