There are numerous TSU9400 configuration files available here in the files section if you'd like to check them out. The available screen area is 240x320. All image files downloaded to the remote are PNG files even if other file formats are supported for use with the editor. Recommend you just stick with PNG files natively. PNG transparencies are supported as well of course. Should also have probably posted this in the Philips Pronto Professional forum instead as you're likely to receive a better response there.
