While writing in onenote, the display on my Surface Pro 7 just froze up with thick lines of digital noise covering a large part of the screen. The display had acted weird with rare but reoccuring graphical anomalies for about a year prior. After restarting the computer it can't get past the Microsoft boot logo. Video output using the USB-C port is completely fine, but although it lists two displays, windows settings shows the built-in display as greyed out (shouldn't a disconnected monitor just not show up?).
Here is what I've tried: All types of force-restarting, draining battery, booting to BIOS (can't display it)
I suspect part of the display is broken for some reason, but what puzzles me is the boot logo. Obviously the LCD isn't completely dead if it can display the logo without problems. What I'm wondering now is what part of the computer is responsible for showing the Microsoft boot logo on the display?
In the second case, I suspect a screen replacement wouldn't necessarily resolve anything if the display board is broken?

- Is it the OS or BIOS? (In this case, this would mean the screen can accept a signal and display it, right?)
- Is it programmed into the display board shown in this guide (step 26-29)?
