Short: LCD monitor test pattern generator Author: Eric Smith (OS4 port by Curtis Holborn) Uploader: curtyh talktalk net (Curtis Holborn) Type: util/misc Version: 1.01 Architecture: ppc-amigaos >= 4.0.0 lcdtest: LCD monitor test pattern generator README Copyright 2005 Eric Smith (OS4 Port by Curtis Holborn, curtyh()talktalk.net) $Id: README 22 2005-05-20 08:01:53Z eric $ lcdtest is a utility to display LCD monitor test patterns. It may be useful for adjusting the pixel clock frequency and phase on LCD monitors when using analog inputs, and for finding pixels that are stuck on or off. lctest uses the SDL library, and has only been tested on Linux with X, but may work on other platforms. Usage: lcdtest [options] Options: --help get list of command keys --list-modes list available video resolutions --window display in a window rather than full screen -x use a video mode with the specified horizontal resolution -y use a video mode with the specified vertical resolution Operation: Upon startup, lcdtest will fill the screen solid red. Pressing keys on the keyboard will change the pattern: Change foreground color: r: red g: green b: blue w: white k: black Change pattern: s: solid fill h: horizontal lines v: vertical lines c: crosshatch a: white vertical lines with two pixel pitch arrow keys: move lines in arrow direction plus: increase spacing between lines minus: decrease spacing between lines 0..9: select predefined line spacings ? or /: toggle display of help message //OS4 Disabled q or Escape: exit program The "a" command is specifically intended for use with LCD monitors connected via an analog VGA (vs. DVI). This pattern should work well for the monitor auto-setup feature. Auto-setup may not get the frequency and phase adjusted optimally, in which case this pattern is also useful for manual adjustment.
