DefectPX 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.

DefectPX 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. DefectPX is easy to use and it has a very
intuitive interface.

DefectPX can be run directly without having to install
it on your computer: just download and run. An
installer program is also available.
