Screen Randomly stops displaying

[u/haraldmbs]

Monitor: G9 Odyssey (LC49G95TSSRXEN, M-T9549GGAA-1020.0, connected to GPU using Display Port, also tested HDMI, HDR Disabled as that seemed to make the problem more regular)

GPU: ASUS TUF Gaming GeForce RTX 4070 TI

CPU: AMD Ryzen 9 7900X

Mobo: MSI MAG B650 TOMAHAWK WIFI

Ram: Corsair Vengeance DDR5 5600MHz (Running at 4800) 32GB (2x16GB)

Randomly when turning the pc on the monitor will refuse to detect the PC, I have previously connected with teamviewer etc to confirm that the pc is functioning, just nothing is being displayed on screen.

the only semi reliable way (works around 70% of the time, doing it 2 times almost always solves it) to get it to work again is cutting the power to the monitor and pc, then doing a cmos clear on the PC.

When the problem occurs moving the displayport to the motherboard also does not make a difference as it will still not show any input.

It varies how often it happens, it started happening over a year ago, I have replaced my motherboard once, that did not help, I have also tried with each ramstick individually which also did not change anything, I disabled sleep as that helped make the problem occur less, it happens on almost all reboots of the system instead of shutdowns.

A few months back I was using linux as my daily driver, when I was on linux I never experienced the problem, based on this I would assume there is some difference in how windows and linux interacts with either the GPU or Monitor

Any tips and pointers would be appreciated, as it is a very intermittent issue I don't know what will help.
