Windows 10: Laptop screen black out if i unplug HDMI cable

I have an Asus Rog Strix G513 2022. I downgraded to Windows 10, AMD ryzen 4800, also with a graphic card NVIDIA GEforce 3050.After i have reformat my computer, my laptop screen will be blank when i turned on the laptop.The screen will only have display if i connect it with a HDMI plug, no matter that hdmi is connected to an external monitor or not.I tried many methods, such as turned off variable refresh rate, power plan with using saving mode and so on.But i have no luck to solve it.Does anyone have the same problem and have solution?Thank you!

Unplugging HDMI cable worked for me

From what I've been reading on this W10 upgrade issue; very few have more than one monitor and most problems seem to be on laptops (mine is)
Considering the amount of complaints with no hard and fast solution that I can see; is it possible for Microsoft to step up to the plate on this issue; I mean these aren't isolated problems by the amount of posts on this forum and thread.

Blue Screen after unplugging HDMI and on battery power

Hello!

Here's the scenario of a blue screen that I can reliably reproduce....

• I'm presenting off my Dell Precision 5510 (Windows 10 Pro version 1709 Build 16299.248, 64-bit, 32GB RAM, Intel i7-6820HQ @ 2.70Ghz) while plugged into power. The laptop is connected to a projector via HDMI, with the screen extended (allowing me to see
  one thing on my laptop monitor and other content displayed on the HDMI connected projector.
• Presentation is done. I unplug from HDMI without toggling to displaying only on my PC screen. I just unplug the HDMI cable.
• I unplug from the power supply (thus now on battery power) but have not turned off the laptop or put it in standby.
• I work on some follow-up tasks..... In a matter of minutes the laptop slows, locks, and blue screens.
• The blue screen code varies, but the message about collecting data never goes above 0%.

If I toggle to displaying only on my PC screen, I seem to avoid the blue screen. Also, if I'm under power, it doesn't seem to happen. Finally, if I unplug from power but don't unplug the HDMI, I'm fine. It's when I unplug from HDMI and go to battery power
that the failure happens.

Nothing shows up on memory diagnostics.

Thoughts? Thanks!
