Projects / lcdtest


lcdtest is a utility to display monitor test patterns. It was originally written for use with LCD monitors, and may be useful in finding pixels that are stuck on or off as well as for adjustment (automatic or manual). However, it can be useful for CRT monitors as well. lcdtest uses the SDL library, and has been used on Linux with X and on Windows, but may work on other platforms supported by SDL.
