• The Combination Test helps you verify your monitor is
properly aligned, and set at the correct color depth and
resolution. Use the crosshair pattern in each corner of
the screen to visually determine if the monitor aligns
correctly. If the crosshairs appear distored or out of
focus, a problem may exist with the monitor alignment.
Use the color spectrum array for visually verifying the
monitor color depth capacity. If the colors in the color
spectrum do no blend smoothly together, a problem
may exist with the monitor color depth. Use the
graduated horizontal and vertical alignment bars to
determine the monitor resolution capabilities. The better
you can discern individual lines as they move closer
together, the higher the resolution capabilities of the
monitor.
• The Solid Color Test helps point out malfunctioning or
dysfunctional pixels using five basic colors: red, green,
blue, black, and white. Fill the screen with an
appropriate color by clicking the associated button. If a
pixedl is malfunctioning, the pixel color will contrast with
the color of all other pixels.
• The VESA Test Patterns allow you to test the monitor for
proper luminance, geometry and focus. Click the
appropriate button to fill the screen with the associated
test pattern. You can return to this dalog by clicking the
mouse button or pressing any key.
