My brother has an Viewsonic VP171B, and today we found a problem. Some time ago we adjusted settings in the OSD, and today he was going to do some more adjusting of the settings, but for some reason he can not access the OSD. No matter what of the four buttons we press, the OSD does not appear. Power on/off button works just fine.
Any clues to why? is the monitor broken? or have it somehow been locked?
