Laptop Monitor to external Monitor

Hello everyone, today I want to show you how you can turn an old Laptop monitor to an external monitor so you are able to use your monitor even though your Laptop passed away a long time ago.

Before we begin here is short story why I am writing this post: Some years ago the first Laptop I bought with the first money I earned on my own (a Dell XPS M1530 to be precise) passed away due to heat problems. All attempts to repair it failed so I decided to buy a new Laptop. Since I did not want to throw my old one away I put it into a box which I kept in my basement. Some weeks ago I was searching for something and found the box I put my old Laptop in and I decided to at least revive a part of my old friend.

Here is a picture of the Dell XPS M1530: (Unfortunately I do not have a pre-broken picture of mine)

Ok. Let´s get down to business 🙂

Here is what you will need:

  • An old Laptop monitor
  • The correct controller board (e.g. this one here is the correct one for my monitor)
  • A 12V power adapter which can provide at least 4A

The first thing you need to do is to separate your Monitor from your Laptop. (You need to open up your Laptop entirely and to unplug all or at least most of the cables to do so)

Now remove the case of your monitor. (This is a bit difficult and you will most likely need to break the case at least partially.)

Now have a look on the backside of your monitor. You should see a serial number like the one shown in the below picture:

The serial number is important because you will need to search for the right controller board before you can continue.

I found this one here on ebay. (The delivery will take some weeks so be patient)

When you have the correct controller board we can continue.

Maybe you will notice a cable like the one shown below on your monitor. (Not all monitors do have this cable hanging around separately but quite many do have them) This cable is responsible for the background lighting of the monitor so be careful not to damage it or otherwise your monitor will stay black.

There should be a port on your controller board where you can plug this cable in.

Now plug in the power adapter and choose a video source to test your monitor.

Your monitor should now turn on and display something. (Maybe you need to choose the video source you want to use in the Menu Settings of the controller board before you can see something.)

Well, that´s it. These are the basic steps you need to know if you want to turn your Laptop monitor into an external monitor.

If you want to build a neat little extra monitor for your laptop or computer here is a good Instructable on how to do this.

I hope you liked my today´s post and I hope to see you again next time 🙂
