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.

Recent releases


Changes: A new diagonal crosshatch test pattern ("x" command) was added.


Changes: SCons-local has been removed, and the documentation was updated to reflect the build requirement of SCons 0.97 or later.


Changes: A minor change was made to CFLAGS handling in SConstruct to support building an RPM package.


Changes: SCons is now used in the build process instead of Make. This should eliminate some reported problems with dependency analysis.


Changes: This release uses SDL Unicode mapping for key events in order to support non-US keyboard layouts.
