v5.0 Guest resolution is not matching window resizing.

It's been a while since I've used VB so maybe I'm trying to do something I can't. The resolution on Guest Windows 8.1 is currently 1152x864. Host is OS X El Capitain public beta. When I try to resize the guest window, I get this for Scaled Mode

and this for Not Scaled Mode.

I thought stretching the guest window used to change the resolution of the OS before. I see the menu option View > Virtual Screen 1 but all the resolutions are greyed out.

They are greyed out because the 5.0 guest additions aren't installed.

Thanks! DIdn't know to look for that.

Installing the GAs will give you a bigger range of resolutions, but I don't think it will resolve the underlying problem, which is that the Windows guest thinks it has a 4:3 display (note aspect ratio of current display size vs that of the window), and so it is helpfully disallowing "incorrect" widescreen ratios. The picture shows it already using the maximum 4:3 ratio that will fit in the window.

I have a solution, but there's no point giving it until it's confirmed that the OP still has a problem.

This was resolved with the installation of the Guest Additions. Thanks.

Most welcome.
