Picture is not stable

1.No picture is displayed for a few seconds in changing resolution (in changing display pixels) such as picture disappearing in a moment, etc.. This is normal function to mask unstability in changing picture.

2.In case of picture moving :

Picture moves due to the degaussing device working after Select "DEGAUSS" (OSD screen) and press the OK button (front control of montor), but it is normal.

In another case, magnetism can cause picture moving. In case there is any magnetics such as high capacity transformers, large current power lines, and electric equipments near the monitor, keep them away from the monitor.
