This menu item launches Monitor Diagnostics, which can be used to check the capabilities and display performance of LCD and CRT displays. This module uses 45 different test screens to help us detect possible issues.
The tests are grouped under four main categories:
- Calibration tests
- Grid tests
- Color tests
- Reading tests
By hovering the mouse pointer over any individual test, we will be given hints as to the goal of the test as well as what we need to pay attention to. We can select which test or test groups we want to run, this way we can focus on specific issues instead of running all the tests.
The test can be run in automatic or manual mode. In automatic mode, the selected test screens will be displayed one after the other, as in a slide show, until Esc is pressed. In manual mode, we can proceed to the next test screen by pressing the Space or Page Down button. In this mode, hints are provided for each test screen regarding what we need to pay attention to. The module contains a predefined test setting for LCD displays, which can be selected in Selection / Test for LCD monitors on the menu bar.
In Preferences, we can choose to save the test selection upon exit in case we want to run the same tests next time. We can also define how often the test screens should follow each other and we can select multi-display mode. On PCs with more connected displays, it is possible to test the monitors with the same test images on each or with a single test image stretched through all.
