Monitor C24RG5 randomly goes black for a second

user1j6s0B5zN2 — Sun, 24 Jul 2022 12:37:51 GMT

Hello, so as mentioned in the title of this post my monitor randomly goes black for a second and then turns back on and it does that all the time, ever since I bought this monitor I had this issue but I could never find an answer, anyone else has this problem or maybe you have a solution?

Thanks

I can definitely understand how frustrating this may be. There may be a simple fix for this. Give this link a shot: https://www.samsung.com/us/support/troubleshooting/TSG01110725/

Also please make sure to check all connections, cables, display settings and to make sure that the firmware is up to date.

If the steps in the link does not help I would recommend also making sure the monitor is also plugged directly to the wall and not through a surge protector.

Also if you have the monitors model LS27R750UENXZA or LS32R750UENXZA, you may need a replacement Y cable please contact us directly at 1 (800) 726-7864 to see if you are still within warranty to get one shipped out.

If none of this helps then this will require service, depending on your warranty you will have a couple of options.

- If your unit was recently purchased, you can check with your retailer on their return/exchange processes.
- If you have an extended warranty you can reach out to them to have service set up.
- If you're within the one year warranty, you can Private message me or one of our moderators or you can call in directly at 1-800- 726-7864 with your full model and serial number to have service setup
- If you're OUT of warranty, you can use this link below to find a service center in your area.

Samsung Neo G9 screen goes black and turns back on (Windows 11 RTX 2070 super)

Spaceway — Tue, 25 Apr 2023 14:58:33 GMT

Hi,

I own the neo G9 (LS49AG950NUXEN) and have a few issues.

I recently saw a post named "Samsung G9 Neo - Windows 11 HDR flickers off and on every few hours" but the thread was stated as solved, so I am creating a new one. I have a similar issue.

After upgrading to windows 11 my monitor keeps going black, like it's changing source, while entering different apps (games, edge, visual studio, whatever) and then it switches back on after a few seconds. When it happens, the OSD displays the current source like it is switching source.

At first I thought it was related to HDR, but it also happens without HDR enabled in windows.

I have updated to the most recent firmware using USB, but the file is from march 2022.

I don't know if it's related, but sometimes I cant wake the monitor from sleep using just mouse/keyboard. I have to press the on/off button on the monitor to wake it up.

I also get pretty nasty scanlines, but I guess that is unrelated and I have sorta learned to live with that.

Hope you can help fix the source/blackout issue as it's pretty annoying.

Thank you!

I should add what I've tried to resolve the issue.

Update nvidia drives.

Changing cable (using the one that came with the monitor) but tried another DP cable with same issue.

Changing cable port on gpu.

Windows update.

I purchased a USB-C to Displayport cable, it seems to have fixed the issue with the black screen flickering, I'm able to run HDR with no problems now.

I just got the flagship Samsung S95C and I have this exact issue on my PC. It's mad I've read people getting this issue as far back as 2019 on different TV models. @Communityuser3049203 any ideas on how to fix this? PC (Windows 11) is all up to date and so is the TV. I never had this issue with the LG C1

I'm having this issue also. Would like an explanation. Why have to cold boot the monitor to get it back on-line?

Same issue here - G9 OLED.

It's a very strange problem in may case. The only time I get black screens (so far) is when using WhatsApp for Desktop, Microsoft Paint, Photoshop, Sekiro FPS Unlocker and ReShade. The only program that consistently causes black screen to happen without even moving my mouse or performing certain actions is WhatsApp for desktop. All the other programs require certain mouse movements or actions to trigger the black screen. It's worth noting that the monitor I had before the G9 OLED was Dell's Alienware AW3423DW,. This panel is provided by Samsung. I never had any of these problems with that monitor. This leads me to believe that the problem has something to do with Samsung's panel software.

For reference I am running Windows 11 with an Nvidia card and an AMD Processor. I am on the latest drivers for both and I have tried using HDMI 2.1 and DP 2.0 and the problem persists (with HDR on and off). I thought it might be Tizen OS (the G9 operating system) but clearly it isn't judjing by the information reported in this thread from other Samsung Monitors of a different ilk.

+1 to this. Same hardware and windows 11.

Bought brand new HDMI 2.1 and DP2.0 cables as well.

Also occurs with HDR off. Going to try turning off Variable Refresh Rate and see if that works.

So far it seems like a firmware update is needed.

Had the exact same issue (screen going black with source name, then coming back, when using Snagit and Trello in my case) and found a fix. In my case, it was caused by G-Sync, and the issue got resolved when I either disabled G-Sync for windowed apps, or disabled G-Sync for the specific apps in the Nvidia Control Panel.

This thread on the 1Password forum has good instructions for both options.

Windows 10 framerate drop whenever 1Password focused — 1Password Community

Hope it helps!

I also got the new Samsung S95C and I have this exact issue on my PC.

tried everything- HDR off -on, gsync off/on, VRR off/on. it continues to occur randomly.

Seems like monitor looses connection with the PC (cable and GPU (4090) no known issues with other monitor). so its something going with the monitor.

Samsung please help- else will be forced to return

I have an Odyssey G7 and I turned “adaptive sync” off and haven’t had a problem since. Hope this helps.

I just setup my G9 OLED and I also have random black screens that last for a couple seconds which is killer when racing. Seems Samsung has no frigging clue how to make a monitor. PS I did update firmware which allowed me to select 5120x1440 whereas it was maxed at 2560x1440 out of the box. I also have Alienware 34" and only problem is pixel refresh appearing on screen randomly

I get exactly the same. Same hardware. 2070 Super, Windows 11, and a G9 (G95TSSUXEN).

Everything is latest firmware or drivers. Tried multiple cables.

Some games and apps will immediately cause the screen to blank and the source banner will come up top left. Then it sits there with the blue light flashing. PC is fine, sound is still working, game or app is still running and taking input but screen is dead. I've had to connect it to a smart switch so I can ask Alexa to power cycle the screen.

And yes, I also sometimes can't wake it from sleep and it has to be hard power cycled.

This has been going on since day 1 of owning the screen and i've seen thousands of people with the same problem.

I'm having exactly the same issues, including the WhatsApp for desktop issue you are mentioning.

I was now trying to do some work on Adobe Illustrator, and each time I click on my artboard, the screen goes to black and then pops back up again with the source switch logo on the left top of the screen. This is making it unworkable.

I already sold my Neo G9, with which I had no issues. Before the CG93, which is giving me this issues, I already had a CG95 which had a faulty oled panel. I returned the CG95 and tried my luck with a CG93. The panel looks great, but now I'm having these black screen issue which is making it impossible to work on PC.

I also already tried, 2 different DisplayPort Cables, 2 different HDMI 2.1 cables, tried all the outputs on my GPU (3090), tried changing the monitor settings etc.

The only thing that seems to have worked for now is to completely turn of G-Sync.
But I didn't spend this much money for a G-Sync compatible screen, to have to turn it off so the monitor works properly.

Hopefully a solution can be provided asap, or I will return this screen as well, and will never purchase a Samsung screen again.
