I never pursued the issue further. My next step would have been to do as you did - namely, reinstall Windows using an alternate BIOS.

I've done that, and still all I get is the 800 x 600 option - nothing more. Anything else I can do?

I have the latest version of unRAID. I've installed a Windows 10 virtual machine. When I connect to the virtual machine with the Windows RDP, the screen resolution of the virtual machine adjusts itself to the size of the window in which I run it - all the way up to 3840 x 2160. However, when I use NoMachine to connect, I can only connect with an 800 x 600 resolution. In its control panel, the virtual machine shows a display resolution of 800 x 600 and no other. Apparently the VirtIO display driver has decided that this is the proper resolution and won't allow any other. The resolution isn't a problem when I connect with Windows RDP. However, I've also got Linux virtual machines, some of which I cannot get to connect with Windows RDP. Therefore my interest in NoMachine. How can I convince the VirtIO display driver to allow me to change the screen resolution of my virtual machines beyond the 800 x 600 that it has so far offered to me?

I'd appreciate your addressing the topic of dockers and bonding of two network adapters. I've had to disable my bonding in order to get the docker to work. Really great tutorials!! I'm glad you're posting them here!
