Getting Help If your monitor does not display an image, check your cable connections and refer to "Troubleshooting" on page 21. If you experience difficulties with the quality of the displayed image, run Auto Adjustment (see page 12) and refer to "Adjusting Your FPD" on page 11 or "Troubleshooting" on page 21. Warm-up Time All FPD monitors need time to become thermally stable the first time you turn them on each day. Therefore, to achieve more accurate adjustments for parameters, allow the FPD monitor to warm (be on) for at least 20 minutes before making any screen adjustments. 10
