Many of you are probably already aware of the problems with running the S95F at 165Hz mode, but just to bring it to the official Samsung forums, it is as follows:
When you connect the TV to a PC and run the display at its full refresh rate, you will get a blue rectangle that flashes up for a frame or two at seemingly completely random intervals. It only occurs when running at 165Hz as that is when DSC is forced on due to the OCB limitation to 40Gbps. Dropping the refresh rate to 120Hz or lower disables DSC and therefore alleviates the problem. Many people are experiencing this issue, here is a reddit thread with a video showing the problem in action.
It was originally thought that this was isolated to those using Nvidia GPUs, but at least one person has reported that the same thing happens when using his Macbook Pro. We've all tried different HDMI cables, using both the different length OCB connector cables, changing various settings and even using custom display timings, nothing except dropping the refresh rate helps.

Yeah, Samsung, it seems that everyone with an Nvidia gpu experiences this issue while in 165hz mode. I have seen comments saying that they've returned their S95F unit and went with a G5 or a Z95B specifically because of these DSC issues. It's really just not a good look as there are tons of displays that do not have DSC issues when plugged into an Nvidia gpu. There is a great number of people who would be very grateful if you guys could sort things out with Nvidia and tackle this issue, myself included, of course.

same happening to me as well. people say putting it on 120hz fixes the issue but for me it just gets worse, it will constantly lose connection (black screen) for few seconds then screen reappears. such u bummer Samsung paid freaking around 1300 Euro's for this tv. apart from this issue everything is perfect.

With my tv it fixes the problem at 120Hz. Too bad it doesn’t work for you.

Just got the S95H, and yep, it's doing it with this TV. I might return it if it did it with the F and is still doing it; then Samsung cannot or will not fix it?

It's odd because I had an S95D which had bad VRR flicker. Then, after about 8 months, they pushed an update that helped, and it went from (don't use G-Sync) to excellent. This is why it's odd how they found a way with the S95D, but I see people complaining about the F and some about the H.
I had an LG C9 (god TV that was), so when I went back and tried the C4 and C6, I am lost as to how they were worse.
I do think all of the companies want the bragging rights, but none of them can nail it. I would say they are more bothered about console owners vs PC.

After testing the S95H for a few more hours, sadly, it does it no matter what you do. Gaming, net, movies. Totally random, it can be once every 20 mins or two or three times. Using the net and movies certainly isn't pushing full bandwidth, so something is really off with how this DSC kicks in, but more so the 165Hz, seeing as how people say it's fine at 120htz. It would be nice to think Samsung can fix it, but it's been like 16 months since the S95F launch, and it's still a thing, so it's not looking good.

I have the same problem with my Samsung OLED QE65S95H. How did you fix this problem? I am using the TV at 120Hz now(because i also get the artifact at 165hz)Thanks for your post it gives me hope and not the only one that is having this problem. @Samsung bring out an update or something to fix this problem!

Sadly, no. I sent the TV back after seeing that this has been an issue for a while, and it's because Samsung is cutting corners with the One Connect box, capped at 40GB. I don't know if they can patch this, since it's partly a hardware/bandwidth issue.
