+# Screen blackout for the Lenovo Yoga Book 9i
+Blackout one screen of your [Lenovo Yoga Book 9i laptop](https://web.archive.org/web/20230723222014/https://www.lenovo.com/us/en/p/laptops/yoga/yoga-2-in-1-series/yoga-book-9i-gen-8-(13-inch-intel)/len101y0028). This is perfect for watching movies on one screen and you just want the other screen to go dark without having to change windows display settings.
+
+The screen will go completely black thanks to the 9i's OLED screens. And it will also prevent burn-ins!
