Windows 10: Use of dual displays configuration

Hello
I just setup my Windows 10 Pro 64 bits for dual display use
It works fine for Photoshop ( my main application) where I have image on one display and panels on the other one
But strange things appear
- When i start Firefox , the image switches to the secondary display
- whan I start Excel, I have no display on the secondary screen

I tried the different options ( expanded, display on both screens ...)

Does that mean that each application should be set to use the dual display configuration ?

Did I forget something ?

Thanks for your help

Annd, wherever you are, take car e of yourself ! Have a good day

is there any demand for a system configurator?

second display configuration issue

Hi All,

My configuration:

Windows 10 Pro x64
AMD Radeon HD 7800

Latest updates and video drivers installed, no hardware changes for 2+ months, latest significant Windows update 2 weeks ago, latest AMD video driver installed at least a week ago.


I have 2 identical displays connected via DVI to Windows PC over several years already with "Extend displays" configuration, and suddenly this configuration stopped working a couple of days ago when I was in the middle of doing something. Windows just replaced it with "Duplicate displays" configuration.


During PC startup I see BIOS diagnostics on both displays. Windows detects 2 displays. "Show only on 1" and "Show only on 2" options work as expected.


Problem: "Extend these displays" results in display 1 going blank and display 2 shows it's part of the image.


AMD Eyefinity (which creates virtual desktop over several monitors) works fine - which suggests that problem maybe only with Windows configuration.


What is done:

• checked cables
• removed and installed again latest AMD drivers
• removed second display from the System Devices, refreshed hardware list and added display again - now I have "Generic PnP monitor" and monitor with correct name in Monitors section
• searched for latest drivers for monitors and display adapters from Device Manager, nothing found

Next I replaced one monitor with monitor from different manufacturer, and everything works as expected - "Extend these displays" configuration shows extended image.


Any ideas what else can be done to fix the problem?


Thank you in advance.
