Windows 10: Monitor turning on but not displaying anything

My desktop computer monitor is not working properly. It is a Samsung Odyssey G3 and when I turn it on it only displays the monitor's backlight for a few moments before going completely black. Even when I have disconnected any HDMI and Display Port cables it does not display the 'No Sources Found' box like it usually does. I tested both HDMI and DP cables with it and got nothing. I tried a different monitor with the same DP cable, and it works fine. I also tried connecting it to my laptop with a HDMI cable and it still showed nothing. Does anyone know the issue and how I could fix it?

Monitor wont display after monitor turned off

I recently build a new system and used an old monitor, no problems. I bought a new monitor and If I turn off my monitor and turn it back on it gives me no display and says no signal detected. I am forced to restart computer several times to get image back to the monitor. Once display is on there are no problems as long as I don't turn off the monitor again. I have read there is a bios update but when I go to Gigabyte page they are listed as F3, F13, F42 and F51. How can I determine which F version my card is?

Also I returned monitor and card with the same products thinking it was hardware issue but the problem remains. I have even reinstalled the OS.

MSI Z97 Gaming 7

Gigabyte gtx 970 G1 gaming
Gskill Ripjaws 2133 16gb

Display Turn Off in Power Options Causing USB Disconnection

Hello everyone, I'm encountering a peculiar issue related to the Power Options settings on my Windows machine (Version 22H2). Whenever Windows automatically turns off my display, it seems to inadvertently cause the devices connected to my USB hub to disconnect. Here's a more detailed description of the problem:

1. Display Turn Off Issue: After Windows turns off the display, my USB-connected devices disconnect.
2. Wake-Up Login Requirement: When I wake up the monitor with a mouse movement, I'm prompted to log back into Windows, as if the system had entered seep mode or logged off.

Steps I've Taken So Far:

• Set Power Options to never enter sleep mode.
• Disabled hibernation and USB selective suspend.
• Restored default power settings using "powercfg -restoredefaultschemes".
• Imported power options from "Default_Power_Plans.zip" found on this forum.
• Analyzed settings with PowerSettingExplorer, but nothing unusual was noted.
• Checked the event log and Sleep Study report ("pwrcfg -systemsleepdiagnostics") for any signs of the machine being put to sleep, but found none.

Interestingly, this problem does not occur when I manually turn off the monitor. It only happens when Windows does it automatically. Also, this issue is not isolated to one machine; it's happening on several, which leads me to believe it's not a hardware issue. I'm looking for any suggestions on how to further diagnose and resolve this issue. Your input would be greatly appreciated!
