    How to connect an External Monitor with Laptop?


    Hi there, I have seen some posts on internet, concerning connecting an external CRT Monitor with a Laptop computer. They pretty much said that there might be a blue cable with, and one can use it to connect that monitor with laptop. Now I am confused that mine monitor has two cables; one of which is blue and the other one is white, having three larger pins inside. Both these wires are connected to my desktop CPU. Now my question is that, it is obvious that the blue wire can be connected to my laptop but what about the other one, this wire is connected to the power supply of my desktop pc, and when it comes to laptop, would mere one wire (blue) suffice for the electricity or other things? Thank you for reading, waiting for your replies. Thanks!

    Typical video connections on a laptop are

    VGA usually blue

    DVI usually white

    HDMI usually gray or black but can come in other colors..

    What connection does your laptop have and match that to your monitors connector..

    do not plug your laptop video output to you computer video output!!

    connections are from computer or laptop to monitor

    Okay! My monitor has two cables, one of which is VGA (as of a projector, for example) and the other one is white (having three larger pins inside coming out) which is a power cord. Now, my last question, is that should I just connect the ble one with laptop and ther white one to a power outlet?

    These are your video connections above.. You can plug the above to your laptop & monitor.



    These are your power connections above

    You can plug this to main power.

    If the power cable to your monitor looks like the bottom one pictured above you will have to swap it for one that plugs into a wall outlet. One like the one that goes from the PC power supply to the wall outlet. I haven't seen one of those old cables that plugged into the back of the PC tower in ages.
