Hi. Sorry to be posting a new topic about this but I have been struggling to find any solution that sorts my problem.
I am running 4.1.14 with OS X 10.7 as my host and Windows 7 as my guest. I am trying to get the resolution for the guest from 1400x1050 (the current maximum) to 2560x1440 resolution (the same as my Thunderbolt display). I have VirtualBox Guest Additions installed and have read the "Configuring the maximum resolution of guests when using the graphical frontend" section of the user manual but none of the code suggested works for me. Since all other topics seem to revolve around this solution I am need of some help. Thanks.
