Vertical monitors let you see more lines of code, reduce scrolling, and keep documentation open alongside your editor. We tested the top options — from the unique LG DualUp to budget-friendly HP 24mh — and ranked them by use case, resolution, and ergonomics.
If you write code for a living, you've probably felt it: the constant scroll-scroll-scroll to see the function definition, the error trace, the documentation tab you keep alt-tabbing into. A vertical monitor — a display physically rotated 90 degrees — gives you roughly 30–40% more visible lines of code than the same screen in landscape mode.2 That's not a small gain. It's the difference between seeing a whole function at once and constantly chasing it off the top of the screen.
The idea isn't new, but the hardware has caught up. Modern monitors come with built-in pivot stands, IPS panels that don't wash out when you tilt your head, and resolutions from FHD to 4K that make vertical text crisp rather than cramped.3
Here's who each pick is for — and why.
The LG DualUp isn't a regular monitor turned sideways. It's a 16:18 panel — essentially two 21.5-inch displays stacked vertically — designed from the ground up for vertical productivity.1 Out of the box, it shows about 50% more vertical content than a standard 27-inch 16:9 monitor. For coders who keep a reference file, a terminal, and a browser open at once, this thing is a revelation.
The catch: it's expensive, and the square-ish aspect ratio doesn't work well for video or gaming. This is a tool, not a toy.
If you work in a dark IDE and want text to look sharp, the Dell U2723QE is the pick. It's a 27-inch 4K IPS Black panel — Dell's newer tech that pushes contrast ratios closer to VA panels while keeping IPS viewing angles.3 At 4K, you can scale the UI and still fit a ton of code on screen without the text turning into a blurry mess.
It also doubles as a USB-C hub with 90W power delivery, so it can charge your laptop and connect peripherals through one cable. Clean desk, happy back.
The U2422H is the gold standard for a secondary vertical monitor. It's 24 inches, FHD, and has one of the best pivot stands in the business — smooth rotation, solid lock, no wobble.3 Pair it with a 27-inch or 32-inch primary display and you've got a dedicated code/documentation screen that just works.
It's not 4K, so you'll notice the lower pixel density if you sit close. But for a secondary screen that lives in portrait mode, FHD at 24 inches is a sweet spot of readability and price.
Front-end devs and designers who also code need a monitor that does both. The ASUS ProArt PA279CV is a 27-inch 4K IPS display with factory-calibrated color accuracy (Delta E < 2) and a fully adjustable stand that pivots to portrait.2
Use it in landscape for design work, flip it for coding sessions. The color accuracy means your CSS colors actually match what you intended. It also has USB-C with 65W power delivery.
Not everyone needs a $700 monitor to read code. The HP 24mh is a 24-inch FHD IPS display with a built-in pivot stand and VESA compatibility — all for under $200. It's not the sharpest or the brightest, but it gets the job done for a secondary vertical screen.
The stand is decent for the price, though you'll want to check the pivot tension out of the box. For the cost of a couple of takeout dinners, you can double your vertical screen real estate.
| Dimension | LG DualUp | Dell U2723QE | Dell U2422H | ASUS ProArt | HP 24mh |
|---|---|---|---|---|---|
| Aspect ratio | 16:18 | 16:9 | 16:9 | 16:9 | 16:9 |
| Resolution | 2560×2880 | 3840×2160 (4K) | 1920×1080 (FHD) | 3840×2160 (4K) | 1920×1080 (FHD) |

Pivot stand. Not all monitors can rotate 90 degrees. If the stand doesn't support pivot, you'll need a VESA arm — an extra cost and a more complex setup. Every pick above has a built-in pivot.3
IPS panel. TN panels lose color and brightness when viewed from an angle. Since a vertical monitor is taller and you're often looking at the top or bottom edge, IPS (or IPS Black) keeps the image consistent.2
Resolution vs. size. A 24-inch FHD screen in portrait mode gives you about 57 lines of code at default terminal font sizes. A 27-inch 4K screen gives you closer to 80–90 lines. If you're using the monitor as a primary display, go 4K. If it's a secondary screen, FHD at 24 inches is perfectly fine.
Cable management. A monitor with USB-C (like the Dell U2723QE or ASUS ProArt) reduces desk clutter. One cable for video, power, and peripherals.

If you want the most vertical real estate possible, get the LG DualUp. If you want a premium 4K primary monitor that pivots, get the Dell U2723QE. If you just need a cheap secondary screen for code, the HP 24mh is hard to beat.
