I don't think I understand. You want to plug your desktop computer up to your laptop screen?

If that is the case, probably not possible.

Possible probably, but if you want portable look at a laptop.  You have to also consider that in addition to the screen you will need a keyboard and mouse.  Additionally the computer does not have a wireless connection, limiting you further.

I was considering something like that and found it un-workable.  The LT screen driver board was not compatible with any desktop output, even down to the component level.

But that is an output from the LT to an external monitor,   Not an input to the display element.

Since you say this is a project using essentially surplus to requirements components, why not ?  Go ahead and see how far you can get.

 

I do think you will find that there is a processing problem. Desktops output a video signal - HDMI, VGA, DVI - and the circuitry in the monitor then determines which pixcels are switched on in what order to give you the screen images we all spend so much time looking at. If I understand it correctly, laptops do this processing on the mobo and pass the finished signal - which includes the information about which pixcels to switch on - to the screen which then merely lights them up.

 

If I am right about this you are setting yourself a fairly challenging project !

the board I have all it does is interpret the signal coming into it I have done basic test and all I had to do was change some resolution settings but I don't know what will happen if I do this long term
