I’m primarily a Linux user and run Linux Mint 20.1 Cinnamon as my primary operating system. I recently installed Windows 10 Professional 64-bit inside VirtualBox to take advantage of a more mainstream operating system.

While I’m satisfied with the successful installation, Windows 10 doesn’t appear to support my laptop’s native Display Resolution (1366x768) and this option is not available in settings, as shown below.

I find it strange that Windows 10 Pro only has five options for display resolution out of the box. I’ve tried many Linux Distros and they’ve always had the resolution I need. Do I have to install some drivers or something to get the full-screen Windows experience? Please advise.

My computer is a Dell Latitude E6530 with an Intel Corporation 3rd Gen Core processor Graphics Controller.

Thank you in advance.

Hello StarFox64, welcome to WindowsQ.

To answer your question, the unsupported screen resolution is not a limitation of your Windows 10 installation , it is a limitation of the default graphics emulator supplied in VirtualBox.

You can overcome this limitation by installing Guest Additions from inside VirtualBox. Instructions on how to do this are in Chapter 4 Guest Additions of the VirtualBox user manual.

The User Manual PDF should be located in the VirtualBox sub-directory. Alternatively, you may like to read the solution in this post:

Again, this is not a limitation of the OS. This limitation is cause by the monitor's driver (.ini) file telling your graphics solution the resolutions that monitor supports. The OS really does not care about resolutions. If 1366 x 768 is the notebook's native resolution, and that option is grayed out, that would suggest the correct Windows driver is not installed. You might need to visit the Dell webpage for your laptop to make sure you have the latest.

I just installed the Guest Additions following the instructions in the VirtualBox manual and Windows 10 immediately resized to fit the whole screen following the installation. It looks beautiful now thank you so very much!
