Hi I currently work as a systems admin, and recently have had problems with various monitors/tfts. If someone was to leave there machine on all night and come in the next morning they are having problems getting the monitor to come back on again. It was act as thought the display cable isnt even plugged in. Any ideas on what could be causing this? have checked obvious things ie monitor switch off have also googled it but found nothing any help would be great as its getting pretty annoying.
