I have a lovely 144 Hz monitor which runs on a DP cable, then I got a Smart 4K TV which runs on HDMI from the same GPU.
The problem is that every time, the TV is off (windows still recognizes the TV) the main monitor is turning full black and back for 2-3 seconds and on every,
this cycle repeats every 5-20 minutes but when the TV's HDMI is disconnected, everything is fine.
The GPU has 3 DPs and one HDMI output but the TV only has HDMI input.
