To aid our evaluation of Cathode Ray Tube based displays we work with a program called Nokia Monitor Test. The software has been designed specifically to help with the proper configuration of any display, but also has the added benefit of illustrating deficiencies in the quality of image being presented.

While glaringly obvious problems would be immediately obvious to anyone looking at a simple page of text, the monitor test program stresses the display to the 'limit'. By doing this we can see exactly where the strengths and weaknesses of a particular display lie.

The program consists of twelve multi-screen tests, each designed to test one particular facet of a displays' qualities. An example from each of the test-screen is shown below.

Geometry	Brightness/Contrast
High Voltage	Colour
Convergence	Focus
Resolution	Moire
Readability	Jitter
