Set up worked perfect fine. Then today it started to flicker. I reset it, I changed hdmi cables, didn’t work. The Wii U I have is fine as well so it’s not the TV. If I use remote play; it displays normally on the phone. And for some reason; if I downscale it to 1080p instead of 4K UHD the flickering goes away. I just want to know what is the issue in the first place so I can pay someone to fix it.
