As mentioned in my last entry, I just replaced my aging Nokia 445Xi 21″ CRT monitor with a new Samsung SyncMaster 213T 21″ LCD monitor. Much easier on my aging eyes that can no longer focus close in, as the LCD face can sit much further back on my desk than the CRT face did.
I thought I’d try to count bad pixels. A Google search turned up various LCD test pattern programs for Windows and MacOS, but none for Linux. So naturally I thought I’d whip up a quick hack to fill this void.
lcdtest uses SDL for full-screen display, and in principle should work on other operating systems as well, but I’ve only tested it on an Athlon 64 running Fedora Core 3 Linux.
