What happened to my display?

I have a damaged LCD screen and the case around it is also bent. I figured it would sell as a desktop because the computer still worked with an external display. I had it hooked up to my television. I found plenty of buyers (because of the very low price), so then my next step was to restore it to factory settings. This seemed impossible. I found one discussion on apple that was very vague and did not explain exactly how they did it. The problem is when you boot the computer in recovery mode, it defaults to the laptop screen. Keep in mind I cannot see anything on the laptop display. After several phone calls with Apple, I concluded and discussed wiping it remotely via iCloud with the find my device feature. This worked, however when the laptop rebooted itself, the image on my television was completed messed up. I have a feeling it can be fixed by restoring it to the factory settings, but now my problem is worse than before because I am unable to see anything. I can hardly see the mouse, and when I tried rebooting it holding down option + command + p + r I got to the screen where the computer asks me (through audio) what language I want to select. Has anyone ever heard of this before? Are there any secret keyboard shortcuts that could help? My screen looks like this:

It would be nice to troubleshoot this myself, but I may have to take it to a store so they can remote in? I have another macbook, but am not sure how to remote in. That would be my next step, but I already have an appointment scheduled. I was hoping to avoid paying their ridiculous prices. Please let me know if you've ever seen this before or if there is a way to remote in and also make it to the recovery startup.
