Screen goes black in game mode intermittently

JUMP TO SOLUTION
I believe this mainly happens while in game mode. But basically the screen will randomly go black for about 2 seconds then come back on. I’ve already returned one tv for this issue. Got the same model (QN65Q6FN) and it is STILL doing it. I’ve tried messing with all the settings. Called Samsung support but they were no help, rep said “don’t use game mode..” .....like what kind of solution is that. That’s half the reason I got this tv- low input lag in game mode. Does anyone have a solution for this? Anyone experiencing the same thing? Any help is welcomed.

I’m 95% positive that this is a cable issue. I swapped out my HDMI cable for one that I purchased on Amazon and I  haven’t had the issue since. Game mode is working great. Here’s the cable I bought:

 

4K HDMI Cable 10 FT - Atevon

Bought my tv (Model#QN49Q6FNA) yesterday, I turned on my ps4 to play and the same thing kept happening. I turned off gaming mode and it still kept happening. Screen goes black for a few seconds then comes back on.

Does this keep occurring throughout your viewing or does it only occur when turning the unit on?

I had it on for about 10-15 mnutes and it kept happening. It happened at least 5-10 times a minute.

I have this problem, contacted Samsung support about it, they had me factory reset, etc. Etc. Nothing helped. Bought this same cable in hopes that it would resolve it, just started playing with it and after about half hour had the same problem again, so it's not the cable and this is not a solution.

 I’m sorry to hear that, the cable seemed to fix my issues. I also turned it off ultimate freesync and that seemed to help. I still get random times where it jumps to TV Plus for some reason but it is far and few in between.

Have been using these same cables with my Q9FN since January without any issues.  These are awesome cables and would definitely recommend.

Actually that's not a solution.   By changing to YUV420 you're using a lower quality color space so you're not getting the full range of colors.  On a PS4 this might not matter if the source game doesn't use UHD color space.  But it's not desirable and you're not getting the best image quality possible.

 

BUT, you are correct, you can downgrade from YCbCr444 (YUV444) to YCbCr420 or even RGB 8 bit and that does indeed solve the problem of black screen intermittently.

 

I have a Samsung curved NU8500 that supports 12bit color ... well it's supposed to support 12bit color (as that is what defines "UHD") but sadly the TV actually doesn't.

 

It's definitely not a cable issue, I use short run 2 foot AudioQuest Carbon cable ($170).

 

I'm surprised Samsung are still having this problem in their newer TV's and don't appear to be addressing it at all.  This is most definitely "false" advertising as the TV clearly doesn't support a true 12bit color space.  Since this problem is obviously VERY common and Samsung don't appear to be stepping up to the plate, then sadly I think this is going to become a class action lawsuit.
