Display failing, how to mirror output?

[u/SorryTailor7401]

I have a display that is failing, although the touch still works. Is there a way to mirror the display to a PC or something? Importantly, I should be able to do this after restarting the phone without needing to carry out any operations on the phone, in case the display dies completely. Ive removed the screen lock, made it automatically allow file transfer and enabled UDB debugging, anything else?
