Best Media Player That Turn Aspect to 21:9 (Top 5 Picks)

If you own an ultrawide monitor or a 21:9 display, you’ve likely encountered the frustration of black bars on the sides while watching videos.

Most movies and shows are produced in a standard 16:9 aspect ratio, which means they don’t naturally fill the width of a 21:9 screen.

The solution?

You need a media player that turn aspect to 21:9, either by cropping, stretching, or adjusting the video to match your screen’s full width.

In this guide, we’ll explore everything you need to know about using a media player that turn aspect to 21:9 and recommend the top options for getting the job done—without sacrificing visual quality.

What Is 21:9 Aspect Ratio?

The 21:9 aspect ratio, often referred to as ultrawide, offers a horizontal resolution that mimics cinematic screens.

It’s wider than the traditional 16:9 format, allowing for a more immersive viewing experience.

This format is perfect for:

• Movie enthusiasts wanting a theater-like setup
• Gamers who need wider FOV (field of view)
• Professionals who multitask with side-by-side windows

However, since most video content is not made in 21:9, you’ll need a media player that turn aspect to 21:9 to maximize your screen’s potential.
