Monitor won't stay off in sleep mode

[msimmons99]

My 27" FT45 monitor (LF27T450FQNXGO) goes into sleep mode and wakes up when it's supposed to. But while in sleep mode it will repeatedly turn on for a few seconds and back off. Continuously and regularly maybe every 10 seconds. What's on the screen is just what it was when it went to sleep; nothing changes there.

What's turning it back on? I've been turning the power off to make it stop at night or it will do this all night.

Thanks!

I have this same exact issue with an RTX 3090.   Please let me know if you find a solution!

Nvidia are working on an updated driver that fixes the issue, I set my screen saver to on and disable display sleep which helps until the new driver is released.

Nvidia just released the 535.98 driver which mentions a fixed issue with "flickering" when waking the monitor. It still freezes the machine for 1-2 minutes after wakeup but at least hasn't locked it up forever so far, neither did I get any bluescreens as before. Also the driver now seems to be logging some failure events in the Windows event log. Looks like they're onto something...

After installing 535.98 driver my Oled G8 does not wake up when booting the computer from shutdown. I need to have another monitor connected to get the signal working. I have a RTX 4090

How do you get the signal to work? I have the latest Nvidia drivers and 4090 and can’t get this monitor to show display; I just bought it too.

I am having same issue, on 4090 Asus Rog Strix; tried new cables, and after reboot or system shutdown and power on; I get black flickering screen, and also it never ever showed bios bootup menut at all.

Might need to return this monitor and get something else its too bad because this monitor is beast.

Hi guys, I had the same issue as you all above with my Oddysey G8 monitor untill today.
I have RTX 4070Ti from Asus connected to my monitor via DisplayPort cable.  I just installed the latest nvidia driver 535.98. It seems to fix my issue. My monitor wakes up when I turn on PC and also when PC comes back from sleep mode.  I will be monitoring this and if something goes wrong, will let you know.

Hola!! Nos puedes dar más detalles como por ejemplo a cuantos bits de color estás, y si estás en 175Hz?? Y también que otro tipo de configuración del monitor tienes que nos pueda dar la solución al problema?? G-sync activado? Control VRR? Etc… gracias de antemano.

This same problem occurs with my G70B 32" 4K  144hz mode. The awake takes too long to be detected, so my second monitor always posts first, causing my Samsung monitor to not post video. I have to hit the power button first, give it a few seconds, then it will awake at the same time as my second monitor. It's incredibly annoying. This does not occur for me with AMD cards, only Nvidia ones, but I think Samsung couldimprove some things regardless.

I would like to see Samsung adjust the firmware so that the monitor posts video first, then worries about applying game mode, or just have it remember game mode better, and prioritizing video post properly.

Same issue, monitor goes black randomly then I have to restart the PC to get it back up. Not sure I’ll be buying another Samsung monitor considering the level of quality control they have.
