PROBLEM SOLVED EASY FIX NOT THE BOX OR THE CABLE
I have a Samsung QLED 4k tv. Ive had the same problem as everyone. Kept losing the connection to the XG1v4 box. (4K)
I just had a Samsung tech connect to my tv and figured it out.
My tv was first connected to a 1080 box. The Samsung 4K TV’s have a setting (settings/general/external device/HDMI HD Color)that takes the 1080 picture and upgrade it to close to 4k..
