I have a Samsung 75 in Q70C 4k UHD tv and when I stream using the in built apps I dont feel like they are streaming in 4k. I have another Samsung tv with a Amazon 4k firestick and when I watch the same show on that one I can see a huge difference. I have looked but I dont know if there is a setting on my tv to adjust or make it better but I haven't seen anything in settings for it. Does anyone have any insight on what it could be or if the apps built into the tv just dont support it?
