Is this the type of flickering others are having?
It was working well before the update. Now if I use anything above 720p I get flickering as shown in the GIF. Even 4k material with a low frame rate setting I get this flickering. I've even tried a factory reset.
Thinking of returning it. It's my only device for 4K material (for now)... thus my 4k TV may as well be a 720p.
Try a different hdmi cable
