My Monitor sometimes doesn't display unless I turn the monitor on wait 3 seconds then the pc..

I'm not sure why this is happening. I've tried multiple HDMI and DisplayPort cables, and I have Windows 11 updated, along with the graphics drivers and monitor firmware. 

 

A few times, I've reset the graphics driver with Windows + Ctrl + Shift + B, which has worked, but only sometimes. It seems to work only when the keyboard lights are on. If the keyboard lights turn on then off during boot, I've noticed that the monitor won't display anything. when the lights stay off but I'm getting 116 volts 3amps I have watt tested

 

Restarting the computer sometimes resolves the issue, but not always. When I connect another display to the PC, it works fine.

 

On one occasion, I enabled HDR, and the screen went black. If the display doesn't turn on, I've managed to log in using my Quest 3 by turning it on or off, which made the display appear.

 

I once turned off Adaptive Sync, and that caused the monitor to display properly, but that only happened once. but I have adaptive sync on now and its working so...idk 

 

I've vacuumed the vents, fans, and boards, and even replaced the CMOS battery, but I'm still experiencing this issue. 

 

I removed my Windows login to make it boot directly to the desktop, as I couldn't see the login screen. However, there are times when it doesn't boot into Windows, especially when the keyboard and mouse lights stay off. In those cases, I know it's not in Windows, and I can't connect remotely.

 

My PC is an Alienware R13, and my monitor is a Samsung Odyssey G9 gaming monitor(software version M-T9549GGAA-1016.0 Latest)

 

idk if it helps I attached DxDiag and inte support utlilty scan of my system

 

also I have reset my OS but still didn't fix the on going problems I had this go on ever since I purchased last yr other people said there was fix but I did everything else... does any of this add up?
