Purpose The resolution of your monitor should meet or exceed the design specifications.
Method First adjust the brightness, contrast, and focus to their correct settings. You should be able
to see individual and distinct stripes in all areas of the display at all four resolutions. Failure
to see distinct lines at the highest resolution (Grill_11) may indicate you have a defective
video amplifier or picture tube.
Note: If multi-colored lines appear on a mask-type color picture tube, you may have a
problem with convergence or you may be exceeding the resolution of the picture tube.
