3D Display Error on Windows 10

I don't know what photo or screenshot I could submit to you since I have no display when the problem occurs. As soon as I connect my 2 monitors, the one connected via HDMI goes black and an occasional message appears indicating that the selected mode is not supported, and it's the main screen, so I have no control over what is running on Windows. My second screen shows what it would normally display, and I am unable to specify which screen is the main one since I can't see anything when I go into display settings; it's on the black screen... do you know how to change the primary screen using keyboard commands?

Same problem still not resolved, how should I proceed please?

Hi, can you send a screenshot of your issue?

However, that's exactly what I did; it's possible that this option appeared because of my graphics card, but I deleted and uninstalled that card and reloaded a new driver and even reset the settings to default, but nothing works; I'm a bit lost...

Thank you seb77150, following your reflections and advice I eventually found the keyboard shortcut to retrieve my display settings and I was able to switch back to 2D mode on my main screen, so there! My issue is resolved.

Phew, I really thought I would have to reinstall Windows 10 and all my applications.

I owe you a big one since I hadn't really looked for the keyboard shortcut for multiple screens before considering your requests.

Thanks again.

It seems that the following solution works:

Try ctrl alt F11 (use the FN key if necessary)

Or

Ctrl alt F8
