There was no adware, toolbar, spyware or other malicious software included within the executable file. As such, this is a portable file that can be loaded up on many different Windows-based computers easily. The installation package is downloaded as a file archive but it only contains a single executable file with no instructions. It is also possible to draw horizontal or vertical lines across the screen to test that they look level and straight without any noticeable gaps anywhere along the line. Gradual color gradients can be used horizontally or vertically. Testing can be controlled via hot keys using keys 1 through 8 which displays a different color throughout the whole of the screen. Depending on the size of the display being viewed, this can be an important feature. In this way, the user has control of the testing process and how many seconds they need to scan the full screen for dead, stuck or paralyzed pixels before moving on to a different color. In the first test, the screen will display a blank page in one color and then with the press of any key on the keyboard the screen color will change to the next test in the sequence. The instructions layout out how to run different tests. When loading the application, it immediately runs in full screen mode without any warning! There are instructions that are converted into the local language on the computer which is a nice touch. The software can be placed on a USB thumb drive and tested on a new monitor or laptop, before it is taken out of the store, to confirm whether the screen has any display issues so that the seller cannot claim that it was damaged after leaving the store.
