Display Resolution Question

Post by saberman »

Host: Windows 8.1 x64 on a Surface Pro 3 512GB machine
Guest: Windows 7 Ultimate x64
Monitor: ASUS VK266 via a KVM switch. Connection to the KVM swtich from the host is via a VGA adapter. Connection between the KVM switch and the monitor is a VGA cable.
VB: 4.3.12

I did not get a response to this: viewtopic.php?f=2&t=63132
and I have experienced a similar incident.

The host's resolution is 1920x1200 which matches the external monitor (see attached host.png).
The guest's resolution is 2400x1500 (see attached Guest.png).
Guest is running in Full Screen Mode not scaled (see attached guest_view.png.

The monitor's specification have a maximum resolution of 1920x1200.

Can someone please explain what is going on?
