We received an important notification from SKC, the vendor for our video equipment.  The LG monitors used on most of our video equipment has an energy saver feature.  This causes the monitor to switch off automatically when it is either not used for awhile or left on for a long time.  This applies to any LG monitor with “LH” in the model number, for example, 42LH30.  To reboot the monitor, push the power trip on the bottom right of the monitor off and on.
