Wrong Display device

[ninglis]

Hi there

 

Has anyone else found a problem with Windows 10 machines when they have 2 display devices connected up?

 

In each classroom I have a static desktop with a pc monitor connected as well as either a short throw projector or touchscreen device. I re imaged all my machines in the summer with Win 10 Pro 1903, and noticed now that everyone of them thinks that the projector or touchscreen, is the primary display device. This means that when you power on the desktop machine, you just get a black screen on the monitor as the computer defaults to Extended display mode and the main display is on the other device. Even if its switched off though. Its caused a lot of problems with the teachers who obviously don't have the sense to turn their projector on and change the computer to duplicate mode.

 

Is there any way to stop this? I haven't been able to find a way to change the priority in the windows display settings. I did find an option on the computers graphics card display settings. But when I changed them round, the touchscreen capability got disabled.

 

Anyone else noticed this issue?

 

Thanks

Depending how you are imaging you could put "C:\Windows\System32\DisplaySwitch.exe /clone" at the end of your task sequence, or in your setupcomplete.bat

I use Microsoft Deployment Tool. What exactly would that command do though? I'd still be able to use 2 displays right?

Sorry, asked my friend google what that exe would do. Good idea, but I'm concerned that it won't do anything about the primary device still being the additonal display device. When someone puts the machine into Extended mode, the monitor won't have the main desktop displayed?

I misunderstood. I have not used it but have a look at Enable/disable/configure multiple monitors on Windows with the set primary command line switch.

Have you checked the graphics driver? I found that when imaging it was auto installing the windows basic graphics driver and it caused me a lot of issues with multi screens. I had to install the machine driver over the top as the windows one was newer.

 

Since then as I image using MDT I now have driver packages installing to prevent the install of the basic driver.
