Following upgrade to Win 10 across college, we are having an intermittent issue with the monitor not duplicating to the Promethean projector, it is often reverting to 'Show only on 1'.
All of our tutor stations have permanently installed PCs, so it is not an issue with connecting and disconnecting a laptop.
Short of 'trying' to instruct staff to use the WIN + P function to correct the display, is anyone aware of a way to force screen duplication as a fixed setting?
Under Win 7 this option was always stable, being a 'set and forget' setting, but it is now starting to drive both us and teaching staff to distraction!!
