Getting Started

Welcome! Precautions

� If you turn on the monitor immediately after power has been restored at an interruption, an LCD burn may occur. This is not a malfunction. The image will become normal after a certain time. On blanking around the pciture The monitor displays black masks between the picture and the screen vessel because the monitor under-scans to obtain the necessary space on the screen to display the picture. This is called blanking. Note that the black masks on each vessel are not uniform. The blanking on the video picture will be wider to optimize picture.

This is because moisture has condensed on the lenses inside. If this happens, let the moisture evaporate before using the monitor.
