When performing the Brightness and Contrast test, the first portion of the test will
have you set your display to 0% brightness. Once you click the measure button it
will take about 10 seconds to perform the test. As your screen will be fully dimmed
it will be impossible to see when the test is complete, please wait about 10 seconds
before turning the brightness up a bit to continue.
Once finished, you can select “view report” to see the results of all the tests.
