How to Watch Videos on a Vertical Monitor: What You Need to Know
Vertical monitors — also called portrait-orientation displays — are popular with coders, writers, and productivity users who want more vertical screen real estate. But when it comes to watching videos, that tall, narrow format raises legitimate questions. Most video content is filmed and encoded in 16:9 landscape aspect ratio, which is the exact opposite of a vertical screen's natural shape.
Here's what actually happens, what your options are, and what determines which approach works best for your setup.
Why Watching Video on a Vertical Monitor Feels Awkward
Standard video content — YouTube, Netflix, streaming services, downloaded files — is almost universally formatted in widescreen landscape: 16:9 or sometimes 21:9. A vertical monitor typically has a 9:16 aspect ratio (essentially a rotated 16:9 panel). When you play landscape video on a portrait display, you get one of two outcomes:
- Letterboxing on the sides: The video plays at its native ratio, centered in the frame, with large black bars on both sides. The actual video window ends up quite small.
- Stretched or cropped video: If you force-fill the screen, the image distorts or significant portions of the frame get cut off.
Neither is ideal — but both are manageable depending on your use case.
Two Scenarios Where Vertical Video Actually Works Well 🎬
1. Vertical-format content (9:16 video) Short-form content from TikTok, Instagram Reels, and YouTube Shorts is natively filmed in 9:16 portrait orientation. On a vertical monitor, this content fills the screen perfectly — no bars, no distortion. If you consume a lot of this type of content, a vertical monitor is actually a better fit than a standard landscape display.
2. Rotated monitor used alongside a second screen Many vertical monitor users run a dual-monitor setup, with one landscape display for video and one vertical display for reading, code, or documents. In this configuration, you simply watch video on the landscape monitor — the vertical one never needs to handle it.
How to Adjust Video Playback on a Vertical Monitor
If you do want to watch landscape video on your vertical display, a few practical approaches reduce the awkwardness:
Rotate the monitor back to landscape temporarily
Most monitors with adjustable stands support pivot rotation. If yours does, you can physically rotate it back to landscape for a viewing session. Your OS needs to match — in Windows, go to Display Settings > Orientation > Landscape. On macOS, the rotation setting appears in System Settings > Displays (sometimes only when holding the Option key).
Use a video player with aspect ratio controls
Desktop media players like VLC, mpv, or PotPlayer let you manually adjust aspect ratio and zoom level. You can:
- Crop the video to fill the vertical frame (losing the sides of the image)
- Scale it to fit the width, accepting the letterbox effect
- Apply custom aspect ratio presets
VLC's Crop and Aspect Ratio options under the Video menu give you direct control over how the frame fits the screen.
Use a windowed player positioned strategically
Rather than fullscreen, some users keep the video player in a floating window sized to a comfortable landscape ratio — essentially treating the vertical monitor like a tall canvas with the video window sitting in the upper or lower portion.
Variables That Shape Your Experience
| Factor | Why It Matters |
|---|---|
| Monitor pivot capability | Determines whether you can physically rotate back to landscape |
| Type of content | Portrait (9:16) vs. landscape (16:9) content behaves completely differently |
| Media player software | Desktop players offer far more control than browser-based streaming |
| OS and driver support | Display rotation settings vary between Windows, macOS, and Linux |
| Single vs. dual monitor setup | A second landscape screen changes the entire calculus |
| Use case frequency | Occasional viewing vs. primary entertainment setup leads to different solutions |
Streaming Services and Browser Behavior
Browser-based streaming (Netflix, YouTube, Disney+) offers less flexibility than local media players. Most streaming players don't expose aspect ratio controls to the user. Your main levers are:
- Browser zoom level — can resize the player window but doesn't change the video's internal ratio
- Theater mode or fullscreen — fills the browser viewport, which on a vertical monitor means maximum letterboxing
- Windowed playback — manually sizing the browser window to a landscape shape within the tall screen
Some users pin a narrow landscape-ratio browser window in the center of the vertical display and accept the unused space above and below. It's not elegant, but it works for casual viewing. 🖥️
When the Setup and the Use Case Don't Align
A vertical monitor optimized for document work or coding is a poor primary entertainment display for landscape video — that's simply a function of geometry. The content format and the screen format are mismatched.
The gap comes down to your specific situation: how often you actually watch video on that screen, whether your monitor can rotate, what software you're running, and whether a dual-monitor arrangement is on the table. Someone who occasionally catches a YouTube video while working has a very different set of tradeoffs than someone who wants to use a vertical display as a dedicated media screen. The hardware, the content type, and the workflow all interact — and the right adjustment depends on which of those variables you're actually working with. 🔍
