Very new to Arduino

Has anyone connected an old laptop monitor ( LCD ) to the Arduino and managed to get it to work? If yes pls forward some info on how to do it. Thx :slight_smile:

It's impossible as I think. Because the monitor is closed commercial product and definitely different with Arduino platform which is open hardware. So that we can not know the circuit connection, not having development kit to dev the app for talking with the monitor ...

All you needed to do was a quick search of the Arduino forum and the answer is always NO unless its a very very old LCD and then you need to invest in some extra hardware and seemingly it runs slower than a slug.

KatyaS is right it is impossible but mainly because the Arduino does not have anything like enough memory nor does it work fast enough. For each pixel on the LCD screen you need a byte ( at least ) of memory. The hardware Ballscrewbob talks of will have that memory on it along with a processor that will constantly refresh the screen and take in commands from the Arduino.

If you want to use anything as massive as a laptop screen then the Arduino is not for you.

You can find LCD (LVDS) driver boards on eBay: m.ebay.com/itm/110977522562
This allows you to connect VGA, DVI or HDMI sources (a Raspberry Pi, for example) to the display.
If you really want to use an Arduino (and I wouldn't recommend it), you could drive a VGA output with an Arduino.
Maybe composite video would work as well.
But don't expect fancy graphics...
