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 ;) from the Category Test Tools for Windows

IsMyLcdOK is primarily designed to quickly become the main feature of the program and that is the search for dead or paralyzed pixels. It is a fairly simple and small test program that can be of great benefit to all PC users. This software requires no expertise in terms of monitors and LCD-s, nor any expertise in the field of screen technology. All PC users can benefit from IsMyLcdOK from the first second
When you start "IsMyLcdOK" for the first time on your PC, you will see a license on the screen. The program is of course free for all, the license info is only displayed the first time (per PC). IsMyLcdOK shows you without detours and immediately at program start all features and test options. However, these can also be called up at any time with the F1 key. From here, you have access to multiple tests that depict colors, gradients, and lines that help ti locate dead or paralyzed pixels. From version 1.01 I added a little "Paint Stress". This will put your LCD under stress simply by the F2 key. You can quit the program at any time with the ESC key.
