If the top of your screen is cutting off at all, this may be due to the display configurations on your particular TV. You should be able to adjust these directly from your TV's settings page. Each TV is unique, but here are a few words that indicate you're on the right track: size, wide, screen fill, screen fit, aspect ratio, or format.
Once you find the one applicable to your display, you'll want to make sure it is set to 1x1 pixel mapping, which means that the data from TransitScreen will map perfectly to each pixel on your TV — this could be called full, fit, or dot by dot. If you can't tell which it is, you can play around to see which fits best.
If you find that the arrival information for certain routes is running off the bottom of the page, let us know by emailing email@example.com, and we'll adjust accordingly.
Generally, our screens are configured for a 1920x1080 pixel resolution. If your display is set to something else, let us know at firstname.lastname@example.org and we will be happy to customize it to fit your specific resolution.
