G7 issue or Graphic card?

[Shamanji]

So today  my pc monitor went to sleep after 10 minutes as i set it too, slumber mode is turned off, my monitor came on after like 2-3 seconds like it normaly dos, but then it turned off or it certainly looked that way for like 5 seconds just

like if you change from 60 Hz to 240 Hz.

My pc Specs :

Amd threadripper 3960x
Asrock Trx40 creator "Latest Bios"
Msi Gaming Z Slim Rtx 4090 24Gb
ASUS HYPER M.2 X16 GEN 5
Be Quiet Dark Power Pro 13 1600w
3x Samsung 990 pro 2Tb
2x samsung 980 pro 2 Tb
1x Samsung 850 evo ssd 2Tb
4x Seagate 4Tb
3x Toshiba 18 Tb
Corsair K100 Rgb Keybord
Logitech G903 Lightspeed
Samsung Odyssey Neo G7 32 Tommer Qled 240Hz 1440p "Software/Firmware 1016,1 Newest"

All drivers are updated to the newest.

After that i ran fine again no issues for like 2 hours atm.

Can this be a monitor 1 time thing or a graphic card 1 time thing? or something else like a coincidence?

I been thinking if it wss the graphics card woulden tje monitor go into sleep mode and show no signal?

Wich it didnt.

Sounds like it could just be a one-time glitch, maybe the monitor resyncing after sleep. Since it’s running fine now, I wouldn’t worry too much unless it keeps happening. Could be a handshake issue between the GPU and monitor, especially with high refresh rates. If it happens again, maybe try a different DP/HDMI cable or check if VRR/G-Sync is acting up.
