How to Fix VirtualBox Screen Resolution for XP Guest OS
Using Windows XP in VirtualBox can be very useful for running old software or testing. However many users face a common problem with screen resolution. The XP guest OS may show a small or blurry display. This happens because VirtualBox does not set the right display drivers by default. In this article you will learn how to fix VirtualBox screen resolution for XP guest OS step-by-step.
Why Does Screen Resolution Problem Occur in VirtualBox XP?
VirtualBox creates a virtual computer inside your main system. The guest OS like XP needs drivers to use full screen and better resolution. Without the right setup XP uses a low resolution mode. This limits the display size and quality.
Main Reasons for Wrong Screen Resolution in XP VirtualBox
No Guest Additions Installed
VirtualBox Guest Additions provide special drivers and features to the guest OS. Without these XP cannot access higher resolutions or auto resize. Installing Guest Additions is the key step.
Old VirtualBox Version
Using outdated VirtualBox software can cause compatibility problems. Always update VirtualBox to the latest version. New versions fix bugs and improve guest OS support.
Incorrect Display Controller Selected
VirtualBox lets you choose a graphics controller for your virtual machine. XP works best with the VBoxVGA controller. Using others like VMSVGA or VBoxSVGA can cause screen issues.
Manual Resolution Settings Needed
Sometimes XP does not detect correct resolution. You may need to set a custom video mode. Using commands like VBoxManage can help create custom resolutions.
Preparing VirtualBox and XP for Best Display
