 Monitor Test
The Monitor Test allows you to easily check for dead or defective
pixels on LCD monitors. You can use it to test a new LCD monitor before purchasing,
or an already purchased monitor during the warranty period (you may get a replacement
according to the manufacturer's dead pixel policy). A defective (dead or stuck)
pixel is a pixel that does not illuminate properly or does not display the correct
color output. It usually looks like an annoying black, white or colored spot on
your screen. The Monitor Test fills the entire screen with one of the colors that make
up a pixel, allowing you to inspect the screen for pixels that do not match the
selected color.
The screen color is changed automatically every 4 seconds (automatic mode) or every time when you press the space bar (manual mode).
