Rhinoceros 6.0 Viewports show black after starting up

When I start Rhinoceros 6.0, only black Viewports appear.
Only if I click on the viewport title, all Viewports will appear. But I can’t rotate or pan in it.
When I click on the Viewport title again, I see that the image has changed or something has been selected or created.
Does anyone know what’s going on?

Hi Fons -
Please run the Rhino SystemInfo command and copy-paste the result here.

Hi -
This section …

… shows that your GPU drivers are 1) very old, and 2) not correctly installed.
Please open the Rhino Notifications panel and follow links to a download site where you should be able to find the latest drivers for your GPU.

I hope that that at least gets you up and running but note that the specs on that GPU are below recommendations for running Rhino 6.

Thanks Wim for your quick response.
