Samsung Odyssey G9 OLED - black screens, connection losses, and more

[ElfVierzehn]

Hello,

I have the G9 OLED for two days and have really lousy problems:

- when I start a game in fullscreen mode with the native resolution of 5120x1440, the monitor sometimes shuts down. There's no way to restore the image until I'm somehow able to either blindly quit the game or restart the PC - sometimes only the reset button helps.

- When starting certain apps or fullscreen applications, I hear a sound like a device is connecting and disconnecting. I also hear this randomly - it stopped, when I disconnected the USB cable from the monitor and ramains happening when I start full screen applications and exit them.

- I randomly have black screens every now and then without doing anything specific. And quite extreme: If I watch a video via any media player, enter fullscreen and move the mouse, the screen goes black for 3 seconds and then returns. If I move the mouse again, the screen goes black again. This goes on and on.

- I am using an RTX 4090 with this monitor. When I set it to 240 Hz, the GPU memory clock rate is not downclocked when the PC is idle. That means the GPU memory clock (not GPU clock) is always running at max clock, which is not ideal for power consumption and temperatures.

I use a Display Port 1.4 cable with 32.4 Gbit/s, but also have an HDMI 2.1 cable with 48 gbit/s. This happens with both cables. As soon as I lower the monitor Hz to 120, the memory MHz goes back to the correct idle value, as it should. Is this a normal behavior?

- when I turn off VRR on the monitor, it is no longer possible to set the native resolution.

The monitor is running on the latest firmware version 1023.

These are honestly such massive problems that I am almost determined to return this monitor to Samsung as soon as possible.

Any input from more experienced Samsung users who have been able to remedy these issues?

Thanks so much!

I've posted all this before but i'm on my 2nd oled after sending back my G95 neo which had dead pixels. the first oled had an issue that it kept saying the screen optimisation wasn't completed and now i've got a couple of issues including the black screening. You've got time to keep posting on here and calling for product recalls really won't happen unless it's a massive number of complaints and certainly won't happen if people aren't complaining to samsung.  Save wasting time on here and make your complaint please

One person (me) isn't going to make a difference. I've been reading up on this issue and it seems to be exclusive to Samsung OLED, not just the G9. Over on the AVS forums, lots of people are having this same exact issue on their Samsung OLED TV, S95C being the main one. Their fix is a new one connect box, which houses the motherboard.

Ok last i'll say on this because I doubt you're going to change your mind and all I'm doing is just elongating something where someone has the unfortunate attitude of they don't want to bother, please don't take that the wrong way if we didn't have the problems there wouldn't be any need for this so I understand the apathy.   But that's part of problem with having that attitude. it isn't about a single person. It's about a collective. Your voice on it's own highly unlikely to change a thing..correct and the more people that have that attitude it becomes even less likely that anything will change. You add your voice to a collective it bececomes larger and then have a chance at making an impact I'm sure I don't need to go any further with the explanation and I don't want to argue with someone when really it's not either of our faults

For me the issue I have is that samsung currently  tend to make the best spec monitors in the sense of what I'm looking for so the option I have going forward is don't buy from them, settle for something that isn't "as good" but perhaps have better quality control. So in future that's certainly something I'll be doing, voting with my wallet.

The way this world works today, us consumers have no voice. It's the big tech tubers. A million of us can complain to Samsung, or any other brand for that matter, and they will blow it off. Once a big tech tuber addresses the problem, then actions will happen. Believe me, Samsung knows about this issue. 

Until someone like Linus addresses these issues, nothing will happen.

Got some good news

They offered me to refund me 100% of the monitor. Or to change it but ***** that I dont want to deal with these monitors anymore 

Would be a shame if the problem was just the firmware

At least they have a good customer service

It's probably a hardware issue as some have zero problems, or have their problems go away when technicians install new panels or they receive replacement monitors. My first monitor war faulty and wouldn't even turn on after a week. The replacement monitor has been flawless, as has been the monitor of a friend of mine who had the whole panel switched out.

All in all it's extremely disappointing that so many suffer from issues with this expensive monitor, and I bet Samsung is really unhappy internally because of how much money they're losing because of their frankly horrible product quality assurance.

I made some changes and after a couple hours of gaming last night, no black screens.

I first disabled G-Sync and turned off VRR in the monitor settings. Black screens still happened but for some reason the monitor feels more responsive and smoother. For an example, in PUBG I have the menu locked at 60fps. With VRR and G-Sync on, menu and mouse cursor felt real sluggish. Now with them off, feels smooth and responsive. I still need to manually change the monitor from 32:9 to 16:9, my Neo G9 did this automatically when I have the in game resolution set to a 16:9 resolution. I also need to do this when playing on my Xbox Series X. Smart monitor, eh?  

So, in Nvidia control panel I changed the scaling option to no scale performed on the GPU, previously it was set to no scale performed on display (which is how I had it set with the Neo G9, which would not stretch a 16:9 image to 32:9). Played for a couple hours and no black screens.    

Edit: Scratch that, 10 mins into my first game I got a black screen in the middle of a gun fight.

Are you on DisplayPort or HDMI? I have GSynch enabled, VRR off, and HDMI, zero blackscreen with this setup, before they happened constantly after the firmware update. Some say GSynch doesn't work with VRR off, not sure really, but it might be working with a lesser fps range.

[ItzTheDay]

My PC is connected via DisplayPort, my Xbox Series X via HDMI. 

When you enable G-Sync in Nvidia control panel, your monitor will automatically turn VRR on even if you had it turned off beforehand. If you have G-Sync enabled and you turn off VRR on the monitor, then G-Sync will be disabled. Double check your monitor settings and you should see if VRR is on or not. 

I believe this is to due the monitor being G-Sync compatible via Freesync. I do not remember my Neo G9 needing VRR for G-Sync to work.  

[Alex452]

VRR stays off from the monitor panel, also, if it wasn't I would have blackscreens and flickering.

GSynch is enabled in NVIDIA control panel and in games, I see no tearing.

The behavior you're describing happened to me with DisplayPort, as soon as I switched to HDMI things changed the way I explained. I don't WTF is going on, but since then, I had zero issues with the monitor.
