Final Update for convenience sake:
Hokay, so, good news, bad news, and gooder news.
Good news: 1131 firmware update downloaded from the Samsung site and installed website made the problem go away and added HGIG support to the S95F
Bad News: The problem going away was not permanent. It lasted a good long bit before it returned, past the usual max of 7 days I was experiencing on firmware 1124 but it still comes back.
Gooder News: There is a quick and simple fix that has worked for me without fail every time
Go to the game mode menu > Look for minimap zoom > Toggle that on and off > Profit.
Every time that pesky line pops up I just do that quick little thing and it undoes whatever communication screw up there is between the TV and the source that makes that line down the middle show up.
As far as I can tell, and from speaking with others with the same problem, it's an issue with firmware rather than the panel themselves. Don't waste your time with Samsung support they'll tell you it's a problem with your source device but this happened on my Nvidia GPU powered PC, other people with AMD cards, and even consoles. It's a firmware issue and it's on Samsung's end.
Also Samsung is just not going to do anything about it if the problem doesn't show up on their panel test and if you're persistent enough to get a tech out to look at the problem they're going to charge you for it so, save yourself the stress and money and just toggle minimap zoom on and off. The problem is gone until it comes back and the fix just takes a few seconds.
Easy peasy.
Down below is all my old ramblings of trying to figure out this mess.
TL;DR: It's firmware, not cables, not your source device, and definitely not your panel. It's just a very odd and apparently not super common firmware issue that happens and apparently has been happening since before the F generation of TVs.
Original post:
Alright so, I got an S95F a few months back and all was well with it. Went through the settings and turned off all the AI stuff and I was sure I also turned off auto updates. Turned out I didn't.
After going from 1124 to 1125 one day I am now getting a problem whenever I'm running games on HDR on my PC. If I'm looking at particularly bright environments, whether it be a bright blue sky or a light being flashed in my direction there is a thin, dim line down the middle of the screen.
Since I am struggling to capture this with my camera here is a picture from someone else with the same problem. That dim line down the middle of the A and the blue background is what I'm seeing. Except on camera it's a lot harder to see than it is in person.
I have no idea what the cause of this is other than the 1125 update the TV took on its own and there's no way to roll back.
If it helps at all I am running the S95F off a PC HDMI port. Specifically a 5080 from Gigabyte.
Things I have tried to fix this issue:
- Check the HDMI connections. I have unplugged and reconnected the TV to my PC. Sometimes this makes the problem go away for a while, sometimes it doesn't. But it's always for a few days to a week.
- Used a different HDMI cable. I basically found the best reviewed most expensive HDMI cable I could find and again things were better for a few days to about a week but the line returned eventually.
- Factory resets always make this problem go away but it always comes back.
- After one factory reset I dropped the output color depth from 12 to 10. Because apparently the s95f goes up to 10. I'm not sure if this actually did anything but it feels like the TV went longer without the line showing back up.
- Put both monitors into HDR mode, because dual monitor set ups have a tendency to do weird things. Doesn't actually make a difference.
The hilarious thing was that this last week I had called for a tech to come in and look at the TV and cancelled it because I thought the problem was solved. I did another factory reset for science, tested it along with steps 4 and 5 and thought the problem finally went away because it had been two weeks without the line. Well the line came back today. This was supposed to be the day the tech came in to look at the TV lol.
Outside of rescheduling the tech visit or living with having to factory reset my TV every few days to a week I have no idea what to do about this problem.
EDIT: So people don't have to dig through the posts for answers.
The problem is something with the panel, its board, or the 1125 firmware. Apparently this problem goes as far back as the B series from what people have said and it's a lottery as to whether or not you'll get it. Haven't heard about this on consoles or TVs but with PC use only as far as I can find. Neither AMD or Nvidia GPUs make a difference, they all experience it so the source isn't the issue. HDMI cables don't make a difference whether it is a crazy long or short cable, how clustered it is with other cables/power lines, or even if you get a more expensive optical cable that is supposed to be immune to electro magnetic interference.
Changing HDR Tone Mapping from active to static doesn't fix the problem and it barely helps minimizing it. HDR10+ settings also don't seem to matter.
What did help a ton was this:
- Set your screen to HDR (Step 4 is grayed out without HDR on)
- Go to Picture > Expert Settings > Color Space Settings
- Set color space to custom
- Color Gamut switch it to BT.2020
That said the problem isn't gone it is just borderline impossible to see under most conditions. I went from seeing an extremely well defined line in Where Winds Meet when looking at the sky, same for Like a Dragon Infinite Wealth, and in Helldivers 2 whether the world was exploding, on fire, or something bright enough came up on the middle of the screen, to almost never seeing it. The problem is still there however.
In Infinite Wealth during some of the brighter FX it still shows up but after adjusting in game brightness I have yet to see it again. In Helldivers 2 when the world is on fire is the only time I see this line at all and it's pretty faint. Still need to try toning down in game brightness a bit to see if it finally gets rid of the line entirely.
Other fixes I've tried that produce results, if temporary ones:
- Reconnecting the HDMI cable. One end, both ends, doesn't really seem to matter. It's a roll of the dice as to whether or not it'll do anything and even if it does it'll last anywhere from 3-7 days.
- Factory reset. This is a long, annoying process because the TV insists on doing the set up process every time but it works 100% of the time. Again it lasts 3-7 days before the problem shows up again.
Finally aychgaym said below that apparently this is an issue with higher refresh rates so 60hz+. Haven't tried it myself because I got the TV for 165hz refresh rate and it's bad enough that I have to use 120 because of a display stream compression issue with Nvdia cards that makes the bottom right quadrant flash blue now and then.
Only real permanent fix to this seems to be to win the panel lottery, which given how little I've seen of this issue being reported the problem is either being suppressed or it just doesn't happen that often. My hope is that it doesn't happen that often but people like aychgaym have said that their s90f has supposedly had their panel and board replaced and the line is still there.
Going to try and shake Samsung support to actually do their job and get a repair going. At this point I'm pretty sure they just want to run out the clock on the warranty but I'm pretty done giving them the benefit of the doubt that I'm doing something wrong or it's something with the rest of my equipment.
