Description

Before and after installing the [guest tools](https://mac.getutm.app/support/) my Windows 11 VM can't change the resolution; it defaults to 1024x768 and the change options are grayed out.

![Screen Shot 2021-11-07 at 20 53 54](https://user-images.githubusercontent.com/12073163/140665178-9d5182d0-0cee-44a0-8531-2a9e6141656e.jpg)

I tried to configure the guest both with `virtio-ramfb` and `virtio-gpu-pci`, the issue remains. The difference is that with `virtio-ramfb` there are two displays shown in the Settings app and in Device Manager whereas with `virtio-gpu-pci` there is only one display. Changing the resolution in EFI does not help as Windows resets to 1024x768 on the login screen. Auto-changing when the window is resized does not work, either.
