How can I display text on a regular LCD computer monitor?

I am looking for a portable way to display a simple menu on a regular flat panel computer monitor for my mobile ice cream truck. Can an arduino do this? If not what kind of micro-computer do I need to look into? I am looking for something like a portable, digital photo picture frame but better (and hopefully cheaper).

You need a device to drive the monitor, and another device to feed the image.
Get the cheapest PC that will run it and PowerPoint it.
