text: how to use an used laptop display as a flat monitor on a desktop pc? i´ve got a unusable compaq presario laptop. motherboard just doesn´t work anymore. i want to rescue its 14" lcd monitor by adapting it to a vga connector and a external dc power supply.   the cuestion is... i don´t know exactly how to. it would be great if someone has the wiring diagram or any information... greater if somebody gives me instructions.  the laptop has a trident video adaptor, don´t remember the specific model. for details i can check my laptop.  thanks trident?    are they still making video cards?  i haven't seen one in....10-12 years i'd guess.  regardless, you would need to consult hp/compaq for wiring diagram, though i doubt they still have it.....but you don't know 'till you ask.  i seriously doubt that you will make this work unless you know how to solder....and well.
