First thought is to use microcontroller to drive LCD. uC can then be connected to PC via USB, for that You need uC that has USART feature. Also, for USART <--> USB comms You need to get TTL to USB converter (try eBay).

Do you want a graphic LCD or a text mode LCD?

For text mode, look at the 16x2 or 20x2 character LCDs based on HD44780 controller. They should run about $10. Then you need a USB microcontroller to control it somehow -- an Arduino Uno for $30 could do it, or a Leonardo clone:
If you want color, look at a small LCD shield like this one: or this one: with a shield adapter:

Then you have to actually program it to display whatever you want! And perhaps program the computer to send information to the display.

Another alternative is to buy a separate Microsoft SideShow compatible USB display, assuming you can still find one... ( )
