virtualbox.org

I am looking for a solution that fix the resolution of my VM to 1280 x 720. I really need these dimensions exactly.

I am on Mac host (Sierra) and using a Mac Guest (High Sierra).

Thanks in advance for any help.

You didn't mention your VirtualBox version, but 5.2.2 has a lot more advanced options for setting the display size. The commands have changed and I can't give you the exact one, because it depends on the VirtualBox version. But you can find more in your user manual (Help » Contents), ch. "3.14.1 Video modes in EFI". So, if you're in 5.2.2 the command would be:

• VBoxManage setextradata "<VM_Name>" VBoxInternal2/EfiGraphicsResolution 1280x720

PS. That PDF that you just opened? It's searchable! Take advantage of it...

Hi Socratis

Thanks for replying.

I am using the last VB version (Versão 5.2.2 r119230 (Qt5.6.3)

I used the command you informed in the Terminal and something was processed but nothing changed. Need I to do something else?

Here it goes.

I'm sorry, but did you notice the command that I gave you? Did you read the manual? The command line that you gave was:

• VBoxManage setextradata "HighSierra" VBoxInternal2/EfiGraphicsResolution HD

which is wrong. I did give you the exact parameters (except the VM_Name) for VirtualBox 5.2.2 and your specific resolution. Please use that.

• VBoxManage setextradata "<VM_Name>" VBoxInternal2/EfiGraphicsResolution 1280x720

I forgto to say that I used this command before use the command you informed. I will try it again.

EDITED: It worked! Thank you so much!
