Retina resolution in Windows VM

Post by jepper »

I would like to set Windows 7 screen resolution to that of the retina screen 2560x1600 without scaling the view. If I do this, the VM just fills up more space than the screen can show, and I have to use scroll bars. If I set full screen the VM sets a resolution of 1280x800 or half of what the retina supports. I use vagrant too, so if it can be done from there (per VM) that would be a bonus. My vagrant file (incomplete):

Code: Select all

Vagrant.configure("2") do |config|
    config.vm.define "win7" do |config|
        config.vm.box = "win7"
        config.vm.provider "virtualbox" do |v|
            v.gui = true
            v.customize ["setextradata", :id, "GUI/MaxGuestResolution", "any" ]
            # here the magic happens!
        end
    end
end

Vagrant isn't supported here.

There are three groups of people. Those that can count and those that can't.

Just to add, Retina displays use "pixel doubling" to achieve HiDPI. That's why when you switch to full screen you get 1280x800 resolution. VirtualBox doesn't directly support Retina Displays/pixel doubling so you are kind of stuck using scaling.

I've seen another thread stating retina support is on trunk. About time. Ticket 10860.

Maybe I will go ahead and buy the 27" Retina iMac after all. :)

I read the Ticket but I don't know how close VirtualBox is to supporting Retina displays. There is a new OSX Test Build along with Guest additions. I suppose if you feel adventurous you could see if they address Retina support. I would but none of my Macs have Retina displays.
