A user-friendly and compact software offers assistance for detecting dead or stuck pixels on TFT/LCD screens. It offers patterned visuals and exercising modes that help fix stuck pixels effectively.
The DPT software was originally written to help the author check their own screens by cycling through the three primary colours and all on/off options. You can easily select a colour and then closely inspect your monitor in each primary colour to locate pixels that are not operating correctly. Stuck pixels (always on) are easier to detect due to their size, whereas pixels not operating at all can be more difficult to locate, usually measuring under .5mm.
The DPT software is freely available for non-commercial use. However, for any other usage, it is requested that you contact the authors. Overall, the DPT software is an essential tool for anyone looking to troubleshoot their monitor for pixel defects. Its user-friendly interface and precise testing make it an excellent resource for individuals seeking high-quality imagery on their screens.
