Projectors have a "FREEZE" option to freeze the display in spite of any change in the laptop display. But, that is a projector feature and needs to be accessed through the projector remote.
I am a teacher and I go to various colleges and use different projectors for my classes. I need to use the freeze option constantly, but sometimes, in some colleges the remote is not available.
So, I was checking out if the display can be frozen by the laptop system, instead of projector. But it is a
tedious workaround.
So, I request for a software which can freeze the projector display, using a button/keyboard shortcut on the laptop.
Thanks!
