How would I use a laptop screen on a desktop pc?

Factual Questions

Hi, how would a use a laptop lcd screen with a desktop pc.

You can’t unless the laptop is designed to take external video from a PC. I am not aware of any current laptops that are designed to do this as it really wouldn’t be a truly useful feature for most notebook users.

Also, Laptop screens aren’t designed to take the output of your desktop PC’s video card. You’d have to find a card that could drive a laptop screen, wire an adapter up, then come up with some video drivers. Some laptops come with a VGA adapter built in.

I’ve seen one done in conjunction with a truck based computer MP3 player. Seems to have taken a lot of work.

I also saw this done with a car mp3 player and was wondering how this was done that is why I asked.

      • POS machines (cash registers) use LCD displays, in different sizes and some in color. Some POS machines are just 486/586 PC’s with special peripherals and added-on hardware, but the screen driver might be contained within the cash register software. ~ Also note that LCD’s and plasma displays are not the same thing; LCD displays run very slow and are poor at showing fast action such as games or video. - MC

There are lots of remote access apps like VNC, PC Anywhere, and Microsoft Terminal Server which allow you to open a remote session. Using one of these, you could use a laptop as a remote terminal on a PC by connecting to it over the network (LAN or Internet).

This isn’t directly using the laptop screen as a monitor for the PC, but using these apps you, you open a window that is essentially the desktop of the remote machine, and you have complete functionality (albeit with some network latency).

Hey, this sounds cool, could you explain this a little more?

What the OP may have seen was a standard LCD flat screen monitor that is designed to run off a PC’s video output being used as a display in a car. These are sold everywhere and you could simply plug it into the same 12VDC to 120AC inverter you are using to power the PC module running the MP3 player.

I think the Diamond RIO MP3 player with a 6 gig drive and integrated display plugged into the line level input of car’s stereo’s amp section for 260 - 300 would be a lot less trouble for most applications.
