I have several old laptop screens but to use with the rpi s it needs a “controller” that takes the HDMI signal from the rpi4 and sends it to the removed laptop screen from an old laptop.  
I did see a universal one with a remote control tho i can not find it now.  
They have them on ebay and you send in the numbers on back of monitor screen, eg. [B116XW03 V.1]

a) does anyone know what i am talking about 🙂  
b) they are like $50 hoping for cheaper  
\*\*C) CAN I MAKE one???  
:- like using a zero or micro controller or is it a totally different thing all together?  
cheers  
Ian

Hi Ian,

Display drivers like the one you’re after are generally very specialised, and process more data than a typical microcontroller can handle. If you can’t find a driver board for your specific panel online, you’re likely out of luck.

All the best with your search though, and props for reusing old gear!

Yep they’re $20 US but probably not much more on top. one of the screens had a controller for $17 so might try that.  
a guy on video had just 1 and went thru and tested it on each of his monitiors and worked on all but one.  
cheers
