Macbook Pro display only works in safe boot or when connected to an external display

Thanks for the reply. I setup a new user and still had the same issue. I also reinstalled the OS and it still has the issue.

It seems like safe boot is disabling certain types of graphic features, which trigger the issue. Are there settings I can turn off to have my normal boot mirror safe boot's graphical settings?

I don't want to spend 528 bucks to send it in for repairs and I don't want to only use laptop when it is plugged into an external device, especially when the laptop screen works perfectly fine when connected to an external display.

Please advise.

Here's a short video showing that the macbook pro display works when connected to another display, but does not when it's disconnected:

Thanks!

So, the built in display been stable for several hours while connected to an external HDMI monitor. I'm going to purchase a dummy HDMI plug as this looks like the most cost effective option: https://www.amazon.com/Headless-Display-Emulator-Headless-1920x1080-Generation/dp/B06XT1Z9TF/ref=sr_1_5?dchild=1&keywords=dummy+hdmi+plug&qid=1621301466&sr=8-5

If anyone can explain why the display won't work without an external display attached, but works flawlessly with an external display attached, I'd love to know. I'm assuming driving an external display kicks in something different on the graphics card which is working properly, but without it, it's saving power and using some part of the hardware that is faulty. Thoughts?

I had an 2011 MBP that never had an issue. 5 years into this model, and it seems like it's reaching the end of it's useful life. Bummer!

Thanks for the note. My MBP has the Intel Iris Graphics 6100. So unfortunately, that option isn't available on either menu.
