question about projectors

Hi Folks

I’m interested in buying a projector to use with my laptop. The laptop has a screen resolution of 1900x900 and anything I buy would be less. What happens? Does the projector squash the picture on my screen into whatever resolution it displays or does it just display a portion of my screen? Maybe it would do either?

Thought somebody here would know the answer

never mind
the mystical google knows all :wink:
found a good explanation
