Portable WTY-DisplayDiag

Portable WTY-DisplayDiag or WDS for short is a suite of small tests for your CRT and TFT monitors, which aim to detect any potential problems in the way these devices function. This doesn't mean you won't be able to run some of these tests on more modern LED screens, for example, but rather that you'll need to somehow adapt the resulting data or simply partially test your monitor using this app.

Probably the most known type of test on any monitor is the Dead Pixel analysis. This involves colored screens being shown on your device, outlining any type of dead or stuck pixel. This is useful for TFT screens. Flashing these images repeatedly on your screen can in certain situations unstuck some pixels. Unfortunately, there is no cure for dead spots on your device.

The Raster test is helpful for non-TFT screens, allowing you to observe and potentially adjust the difference between light and dark shades. This mode will display a number of different screens with various patterns in black and white colors. Quick setup is especially useful for adjusting brightness and contrast levels. The same goes for Color Setup, which is also useful in detecting color intensity.

If you've just purchased your monitor and would like to make sure it doesn't have any hidden issues, running a Burn-in TFT test will rapidly heat the display by cycling through a bunch of colored backgrounds until any unstable pixel might come forward on your device. You can also use the Display Info option to understand your monitor's particularities.

The app will display information in either a short or more complex version, all depending on what data the monitor itself can offer to the app itself. Portable WTY-DisplayDiag is a great tool to carry on your USB drive. It can help you diagnose problems with TFT and CRT screens, and also run some basic tests on all other screen variants out there.
