USB or Serial cable for a projector?

I am wondering which cable is better to use for a projector, serial or USB. Also, please furnish me a reason why.

USB or Serial cable for a projector?

To connect to a projector to produce an portrait you need a video cable. VGA or DVI depending on the projector.



A lot of projectors own a USB port. However this is not for the image but to allow the projector remote to conduct yourself like a mouse.



Again greatly of projectors have a serial association, but again this is not for the display, but allows a computer to control the projector - turn on/off, select input etc.
For a projector? I've never heard of a USB projector. Most projectors are going to enjoy a VGA input for a PC, and you should use this input.
VGA works fine, it's pretty much standard, plus with VGA you shouldn't hold to deal beside any driver issues.
For best quality use DVI the white rectangle one but if you dont own it which only expensive ones do use the Blue VGA one its a Blue Rectangle.
