I recently discovered that the display resolution on my virtual machine is 640x480, which is a very low resolution. I have tried again and again to change it - as seen in the picture above - but have had no luck.
Here's the specs of the guest VM:
3674MB RAM,
3 Processors,
Boot Order: Hard Disk, then Optical and then Floppy disk.
Hardware Acceleration: VT-x/AMD-V, Nested Paging, KVM Paravirtualization.
Video Memory: 43 MB,
3D Acceleration.
I want to use this VM regularly and would appreciate help.
