This is a program for tesing the quality of CRT/LCD screens. It displays various patterns and allows you to estimate the quality of your CRT/LCD monitor.

See the file NEW_TESTS.md for details on adding a new test screens.

This program is postcardware. Read the top of the file "COPYING" and send me a postcard, if you want. Let me know on what system you have tested it, so I can estimate the userbase and portability of the program.

Please let me know what can I do for improving screentest. Use the e-mail [email protected] or report an issue on GitHub.

The installation of this program is pretty straightforward if you are familiar with using the command line:

You will need the following libraries to compile this program:

• GTK+ >= 2.0 (tested on 2.10.13)
• glib >= 2.0 (tested on 2.12.13)

You will need both the libraries (either in static or dynamic form), and their header files (which may not be installed on your system by default; for example, check for gtk+-devel, glib-devel and XFree86-devel packages on Red Hat Linux or Mandrake Linux). This also assumes that the "pkg-config" command is in your PATH.

The source of screentest is available at the GitHub release page: https://github.com/TobiX/screentest/releases

You will also need the ISO C9x-compliant C compiler. This program uses ISO C9x-style structure initializers, so this is a NECESSARY CONDITION. You can use for example gcc-3 or later, which is available on most Unices.

The build process has been tested on Debian unstable (www.debian.org), but should work on any recent version of UNIX-compatible system.

Unpack the distribution using the following command: tar xvzf screentest-.tar.gz Change the directory to the source directory: cd screentest- Set it up for your system: ./configure You can run "./configure --help" for details of the configuration process.

Run "make" (On BSD systems, you might want to use "gmake"). This will compile the "screentest" program. Since the program is mostly standalone, you can now verify their function by running them in the current directory (calling "./screentest").

Run "make install".
