VB 5.2 Version changing Resolution temporally when Guest is running

[joseluisbz]

Hi,

I was changing the resolution time before of my macOS guest was started.

Code: Select all

$ VBoxManage setextradata "MacOS 10.12 Sierra 64bits" VBoxInternal2/EfiGraphicsResolution 1920x1080

But I was thinking to connect to another Screen with before resolution HD, 1920 x 1080.

But when the TV or Screen is unplugged the Guest (macOS Sierra) is shown not properly.

I want change the resolution when my Guest is running temporally (not stop + change resolution + start).
When the my guest is restarted take the resolution stablished permanently.


For me the best options is:

• Step 1 :

  Code: Select all

  $ VBoxManage setextradata "MacOS 10.12 Sierra 64bits" VBoxInternal2/EfiGraphicsResolution 1440x900

  Step 2 :

  Code: Select all

  $ VBoxManage startvm "MacOS 10.12 Sierra 64bits"  --type headless

  Step 3 : Connect my Host to Screen or TV
  Step 4 : HOW TO DO THAT?

  Code: Select all

  $ change TEMPORALLY to Higher Resolution 1920 x 1080

  Step 5 : Disconnect my Host from Screen or TV
  Step 6 : HOW TO DO THAT?

  Code: Select all

  $ Restableshing to HOST Resolution 1440 x 990 Again

Please tell me How to do that?

You can't do that. The resolution is set at the beginning, there is no dynamic screen resolution changes for OSX guests. For that you would need the Guest Additions for OSX guests, which do not exist.

Again I'm frustrated. Thank you for your answer.
