Displayswitch and zooming of display

[Sheridan]

We're trying to setup a method that will automatically duplicate the main (i.e monitor) display to the secondary (i.e projected/large screen ) display and keep the display at 100%

 

So the user's registry preferences set the display to 100% - this works fine. If the user initials the Windows+P option and selects Duplicate it works fine. However we scripted it to run this (displayswitch /clone) on login, which also works but flips the view to 150%

 

This is rather annoying as a) we force the display to 100% and b) where does it randomly decide to select 150% from!?

 

Has anyone found a more reliable way to duplicate screens on login? Our staff seem unable to remember the Windows+p option so I'm trying to force a default!

Use a hardware distribution amplifier (splitter)? PC only sees one display. Does totally prevent anyone from using Extended display though - which works great for us but may not for you!

Thats the issue, some use Extended, some never use it!

Does running the command 'displayswitch /clone' work? If so, you could have that set to run at login for the users.

That's exactly what we're doing, as soon as that runs the display duplicates, then flips to 150% which makes it look rubbish!

My bad - had a brain fart whilst reading your post!

Does changing both of the displays whilst extended to 100% stop this?

There is a registry fix here:
