Hi,
I´m kinda at a dead end. I work at a public school in Denmark, where i´m the local IT-guy. The staff has Lenovo T-470´s, and after getting updated to Win 10, we have problems with the resolution on our projectors in the classrooms.
They are primarily NEC´s that run 1280x800, and most staff would like to run the setup in duplicate mode.
When i select the resolution to be 1280x800 in duplicate mode, it scales the screen on both the laptop and the ext. output, but the signal is still 1920x1080. On the NEC´s a Full HD signal is kinda cloudy and smaller image, while other projectors blink.
The main IT-department just brushes it off, and tells me that duplicate mode is not supported in Windows 10, when running lower than Full HD. It worked flawlessly in Win 8.1.
I´ve tried to mess around with the image from the IT-department, and also stand-alone installations with no luck.
Is it really just the way WIndows 10 works?
I´ve got an education in IT, but my colleagues at other schools are teachers, and not of much help to resolve this issue.
Main IT-dep. doesn´t care much about schools, so i´m kinda on my own.
Regards, Michael
