I’ve created Windows 7 virtual machine on Windows 8 Hyper-V, but can find how to set resolution to anything widescreen (my monitor supports 1920×1200) to be able work fullscreen.
There are two ways you can do this:
- Change the resolutions within the remote OS
If connecting to a Windows OS, connect using Remote Desktop Connection instead of Hyper-V Viewer.
Using RDP allows for more functionality including Client Screen Size, Audio, and Remote USB integration.
