Display too small

Total noob here.

Bought a box to use as a music player/email and web surfing box in our family room, using the tv as the display.

The RB display is too small to allow me to read any of the text of the screen. Is there a way to change the size of the fonts RB displays so that I can use it more easily?

My display setting is 1024 x 768, which is the only setting that allows the desktop to fit in the TV without either a black bar on one side or with a lot of the desktop off the edges of the screen, so changing the display resolution won't work.

Thanks for any help.
