yes as long as you have an external connection on your laptop. most laptops have a analog (VGA) connection but very few have digital (DVI)connections. Some have S-Video but unless it's also a TV you do not have to worry about this.

Just find out what you have and what the monitor you want has. if your laptop is old (older than 2 years), find out what graphics card it has so you can find out the max resolution.
I hook my laptop up to a 21 inch LCD at work via a dock that has only an analog connection. Works great.
