How to add new resolutions to VirtualBox

VirtualBox is an open-source, cross-platform Virtual Machine Software equivalent to NB. However, the newly created virtual machine only supports several resolutions. For example, to install win8.1, there are only several resolutions.

However, my monitor is 5 K. The resolution is just funny. Unfortunately, the virtualbox GUI does not provide the resolution adding function, but it provides a command line tool to add resolution of any size. For example, to add a resolution of 2560*1440, run the following command.

VBoxManage setextradata "win8.1" CustomVideoMode1 2560x1440x32

VBoxManage is a command line tool, for example, OS X. This tool is in the/Applications/VirtualBox. app/Contents/MacOS directory. For linux and windows, find the installation directory in virtualbox.

Win8.1 is the name of the created Virtual Machine (double quotation marks are required on both sides). mmvideomode1 is the resolution name currently set. If the name is duplicate, the resolution of the previous setting will be overwritten. The 32 in 2560 C 1440x32 is the color bit (32-bit color), with the lowercase x of 26 letters in the middle.

You can set this parameter no matter whether the operating system is started or not. If the system is running, restart the system.

VirtualBox is a powerful x86 Virtual Machine Software with rich features and excellent performance.
