Eizo Monitortest is a free software program for Microsoft Windows devices to configure and calibrate connected computer monitors.

If you bought a shiny new computer monitor you may want to ensure that the monitor is calibrated correctly. While the picture may look fine on first glance, calibration ensures that you get the best possible picture out of it.

This is also important for computer monitors that are already in use, as you may calibrate them to ensure that they display the best possible picture.

A monitor that is not properly calibrated may display colors incorrectly for example, or cut off part of the screen so that you cannot see part of the picture when you are working on the computer.

There are basically two different parts when it comes to monitor calibration. The first is to ensure that the screen is positioned correctly, the second that the colors are calibrated so that they display as they should.

Eizo Monitortest is but one of many computer monitor calibration software programs available (read: Online Computer Monitor Calibration, Monitor Calibration Wizard, or Calibrate Your Flat Screen Computer Monitor for additional options).

The Eizo Monitortest tool has been developed for Eizo computer monitors. It can however be used to calibrate monitors on all computer systems regardless of the monitor brand used.

The calibration tool is available in three different languages. It displays a series of test screens on startup that can be used to calibrate the monitor correctly.

To use it, you use the controls at the bottom of the window. Use the left and right buttons to load the previous or next test, the information button to display information about the monitor and the test selection options, and the exit button to terminate the application again.

It does not provide a lot of explanation about the tests but its 24 tests should cover all aspects of the process. Tests can be deselected from being run in the program's settings. The following tests are performed by default:

  • Autoadjust Test
  • Basic colors test
  • Moare test
  • Gemoetry test
  • Brightness, contrast, homogenity
  • Convergence test
  • Speed test
  • Sharpness test

Eizo Monitortest is a portable application that can be used to calibrate computer monitors. It is available for most Microsoft operating systems and for MacOSX.

Please note that the program is offered on the German Eizo website. Just click on the download button to download it to your system. When you run the application, flags are displayed in the upper right corner that you can use to change the interface language.

Closing Words

Eizo Monitortest is a professional monitor calibration program that is freely available. Designed for Eizo monitors in particular, it is not restricted to calibrating those. While it may take some time going through all the tests, end the end result may very well be worth it.

    It’s worth noting that Eizo test is useless on monitors that don’t have manual controls for things like geometry and convergence. It also does not perform accurate color correction beyond basic brightness and contrast, so if you want to be able to display correct and consistent colors, say for pro photo work, you’ll still need to go with a hardware color correction system.
