I have my surface pro 3 set up to use two displays. If I extend the display from the surface pro 3 the orientation on the monitor is correct. But if I use the setting 'duplicate these displays' the monitor only switches into portrait mode and is unusable. My screen rotates 90 degrees on the monitor. I tried the method of removing cables from the monitor and pressing the power button for 15 seconds and it had no effect. There is no menu button on this monitor ? This monitor was fine yesterday. It got messed up after I used my surface pro 3 with an unlocked rotation. Now I can't get it back to a reasonable state.
Thanks!
