If you open up the "Advanced Configuration" app, and go to "Display" you can set font size there. But beware that font size can also be stored in the themes' .ini-files, so depending on your choice in theme, you'll have to check that also. Best resolution for your TV is depending on if you use S-VHS, composite, component-RBG or Scart-RBG inputs. If you're using S-VHS, then I would recommend 1024x768 or 800x600. I'm not sure what you mean with "background images", do you mean the desktop wallpaper? Emph
