1) Adjust your contrast to the maximum setting.
2) Adjust your color settings until the entire test pattern looks black, white or gray.
3) Adjust the brightness so that you can see a clear difference in the two
darkest squares below and to the right of the center of the pattern
while keeping the darkest square as dark as possible.
4) If you cannot adequately distinguish the two dark squares,
borrow someone else's monitor.
