Ok, so I've found a panel from a mostly not working Dell U2417H somebody was selling for $15. Next step is to order some sort of controller to see if the panel works.
 

 
I was looking at this one: https://www.ebay.com/itm/161076658712
And I've sent a message to that seller asking if it would work with the panel. The panel model is LM238WF4-SSA1 btw.
 
I've got as far as confirming the back light works and the brightness can be adjusted with the display controls. There is no signal however and when I wiggle the ribbon cable on the end connecting to the controller board I can get some color to show up. so idk if it's a panel problem or a controller board problem or a ribbon cable problem. But I really can't go wrong trying for $15, and it is a high quality panel if it does end up working.
 
EDIT: I've also realized this might not be the right sub-forum for this thread. Is there a better place for this project to be?

Looks like this ebay retailer is good too: https://www.ebay.com/str/lcdtech99
 
The prices from there and https://www.laptopscreen.com/English/ are just so much more expensive than alibaba it kind of makes me want to just experiment a bit and try out one of the cheap 4k panels from alibaba. I'd be really interested to see if anybody has any experience whatsoever with those types of panels.
 
I'm totally in the research/learning stage atm so any and all leads are helpful
