IsMyLcdOK

IsMyLcdOK is a lightweight and portable application that allows users to verify LCD monitors for dead or stuck pixels, by proving them with a series of standard tests. It can be easily handled, even by users with little or no experience in computer software.
Since installation is not a requirement, you can just drop the executable file anywhere on the hard disk and click it to run.
It is also possible to save IsMyLcdOK to a USB flash drive or similar device, in order to use it on any machine effortlessly.
An important aspect to take into account is that the Windows Registry does not get new entries, and files are not kept on the hard disk after removing the utility.
The interface is based on a full screen window with the main options listed. You can perform a white, red, blue, or purple test, gradient horizontally, vertical lines, paint lines, black, green, cyan or yellow test, and others.
It is possible to select any of these options or go through all of them by navigating with the Space bar. From this point on, you have to rely on your own observational skills to detect any problematic pixels. If nothing is spotted, it means your LCD monitor does not have any pixel issues.
IsMyLcdOK offers multilingual support and works smoothly on newer operating systems, using low CPU and RAM. We have not come across any issues in our tests, since the app did not hang, crash or pop up error dialogs. All in all, IsMyLcdOK delivers a straightforward method for checking LCD monitors for dead pixels.
