Display Tests
Run the screen display tests to verify that all the screen pixels are
working and that the brightness and contrast samples appear to be
within normal range. There are no screen display adjustments. The
screen display tests are as follows.
Pixel Verification Test

any missing pixels on the display.

screen in this test mode over night to remove the “burned-in” look to
the softkeys.
Press the enter key to exit the test.
