Quote: Would it be correct to say that the issue you are experiencing is when connecting to the VM by using “Launch console” feature in Prism? Here is a KB describing the issue that you encountered specifically KB-4792 AHV | How to change display resolution on Windows VMs running in UEFI mode. AFAIK, sysprep defaults the resolution to 1024 x 768 – something to keep in mind. I would recommend to sysprep the OS prior to making an image out of it. Have you considered deploying VMs from an image? This way you can skip the installation phase entirely and arrive at initial set up. The thing is, VNC is intended for troubleshooting, debugging and such rather then as a all time access tool.ĭoes the issue appear when you connect via RDP post the installation? RDP is using a different driver hence you should be able to adjust the screen as required. Therefore, you would need to change the resolution settings in UEFI in order to affect VNC connection resolution. Would it be correct to say that the issue you are experiencing is when connecting to the VM by using “Launch console” feature in Prism? When using “Launch console” screen resolution is picked up from UEFI settings and Windows driver does not have the ability to change that setting.
