Hello everyone,


I recently bought a new PC with two new screens. When I boot it up, both of the screens show a "no signal" message even though the PC is running.

Only when I unplug the displayport cables from the GPU and then plug them back in, the monitors start to get a signal from the computer.

From then on everything runs perfectly until i turn off the PC. When starting it, it is the same as before.


Hardware:

CPU: AMD Ryzen 9 7950X
CPU cooling: 240mm-Radiator - Cooler Master MasterLiquid ML240L V2 - ARGB
Memory: 64 GB DDR5 5200 MHz (4 x 16 GB) - CORSAIR VENGEANCE
GPU: 24 GB GDDR6X - NVIDIA GeForce RTX 3090 Ti - ASUS TUF O24G GAMING
Mainboard: MSI MPG X670E CARBON WIFI (Chip: X670 / ATX / DDR5)
M.2 SSD: 2 TB M.2 PCIe 4.0 x4 - Samsung 980 Pro
Power: 1200 Watt - be quiet! Straight Power 11 Windows 11

Screens: MSI MPG321URDE-QD 32 Inch, 4K, 144hz, 1 ms, IPS Panel, HDR600
Samsung Odyssey Gaming Monitor G7A LS28AG702NU, 28 inch, 4k, 144hz, 1ms


Cables are new and should be perfect for the hardware.

Any ideas?
cheers :)

I also own this monitor with a 12gb 3080 and after the firmware update with the addition of premium color from the OSD etc. Then using the supplied 8K HDMI 2.1 cable with its extra bandwidth. It is the perfect monitor
