This post will tell you what you can do if the bottom half of your Windows computer screen turns black. It could be a driver or hardware problem.

If half of your computer screen is blurry on Windows 11/10, roll back or reinstall GPU driver, change Refresh rate, update monitor firmware, etc.

Flipping the screen in half could allow someone else to view the display while a person is working on the laptop, or maybe they just want to use a regular-sized screen for a while.

Splitting your screen allows you to run multiple apps or browser windows on your computer at the same time, making it easy to multitask.
