Problems with the Displayed Image
A combination of incorrect on-screen display (OSD) adjustments can cause
problems with the displayed image. In this circumstance, a good first step
toward a solution is to select the Factory Reset icon located under the OSD
Control selection in your OSD. This option automatically sets the
adjustments to their optimum settings for your particular computer. This
sets up your monitor with standard video timings and provides a good
starting place for fine-tuning adjustments.
