Settings for Composite Video Output

So I apologize in advance for any stupid questions - I just moved from Arduino to Propellor and I'm still trying to figure a lot out.
Anyway, what I'm trying to do is output a 640x480 monochrome image to an LCD, but I seem to be running into some problems. For one, when running the standard demo code, the top and bottom of the image seem to be cut off (I've read this might be an overscan issue). I'm also unsure as to how to change the resolution for the composite output. I know 640x480 would generally be a fairly high resolution to work with, but I figured that running the display in monochrome (1 bit per pixel) would work.
Any advice on how I should get started with this? Anything helps. Thanks so much.

The code that comes with the Demoboard does have the image cropped, due to RAM constraints, because it's also doing a VGA display at the same time.
Get to where you can run graphics_demo.spin, and see the entire default graphics image. From there, your questions can get answers.
