Having an issue with loosing projectors...  teacher emails.. "projector not working." Display properties shows only 2 monitors and no projector. hdmi epson projectors, displayport dell interactive panels, various other display devices. rebooting does NOT fix. redneck solution.. turn off, unplug, press power to discharge power supply.. plug back in, turn back on.. everything works.... (only the power cord.. nothing else) ideas? all firmware is up to date on the pc. windows 10 distro that came with the units. multiple units are having the issue.
