Screen resolution is a common issue faced in VirtualBox, it could be easily fixed by creating a custom screen resolution, please follow the steps below.
Switch off the Operating System installed in VirtualBox.
Step 1: Navigate to VirtualBox installation folder, open command prompt
Step 2: Enter command VBoxManage.exe setextradata “Operating System Name” CustomVideoMode1 1366x768x32
- Replace “Operating System Name” with your operating system name
- CustomVideoModel name with any name you want to give to resolution.
- 1366×768 with the resolution of your system.
In my case the operating system is “Windows 10 pro”
Command will be.
Step 3: Settings on guest operating system
Now start the guest operating system, right-click, select “Display settings”
Click on Resolution
Custom screen resolution will appear in the list, in my case it’s 1366×7687. Select it.
Bingo! done 🙂
Similarly, it can be done for any operating system.
