IsMyLcdOK is a small program but effective solution to easily check for dead/paralysed/stuck pixels on LCD monitors.
Many manufacturer?s provide the highest industry standard dead pixel policy.
IsMyLcdOK does not have to be installed and can be executed easily from the desktop,
and can be carried on a small usb-stick or other memory device.
Testing for dead pixels is very simple.
