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 <count> use a video mode with the specified horizontal resolution
-y <count> 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.
Dependencies:
