The Best Monitors for Coding: 4K, Ultrawide and 3:2

Text is the whole job. A monitor for coding needs to render small, sharp glyphs for ten hours without fatigue, fit as many lines as your eyes can handle, and ideally charge your laptop over one cable so you never think about docks. Here are the five we would buy today.

The three numbers that matter

Pixel density. Around 160 pixels per inch and up is where text starts to look like print. A 27-inch 4K panel lands at 163 ppi. A 32-inch 4K drops to 138 and you will see it in thin fonts. Apple’s 5K at 218 ppi is sharper still.

Vertical pixels. Code is tall. More vertical space means more lines without scrolling. A 3:2 or a 16:10 panel gives you that. An ultrawide gives you two full editors side by side.

Connectivity. Thunderbolt or USB-C with enough power to charge your laptop turns the monitor into the dock. One cable then connects everything on the desk.

Refresh rate matters less than for gaming, but 120 Hz does make scrolling through a long file noticeably smoother.

#1 Best overall

Dell UltraSharp U2725QE

Check price on Amazon

• 27-inch 4K IPS Black
• 120 Hz
• Thunderbolt 4 with 140 W charging
• Built-in KVM and RJ45

Pros

• +Sharp text at 163 ppi
• +Thunderbolt dock built into the monitor
• +Deep blacks for an IPS panel

Cons

• –Pricey for a 27-inch
• –Stand is basic
• –Speakers are weak

Dell’s IPS Black panels roughly double the contrast of a normal IPS, so dark editor themes look dark instead of grey. At 27 inches and 4K the text is crisp. The 120 Hz refresh is a quality-of-life upgrade over the 60 Hz standard. And the back is a full dock: Thunderbolt 4 with 140 W to charge a hungry laptop, Ethernet, a KVM for switching between two machines.

It is not cheap for the size. The stand is adequate. On a monitor arm, the stand stops mattering.

#2 Best designed for code

BenQ RD280U

Check price on Amazon

• 28.2-inch 3:2, 3840 x 2560
• Coding mode with tuned contrast
• Backlit function hotkey
• USB-C 90 W

Pros

• +Extra vertical space fits more lines of code
• +Matte finish kills reflections
• +Night mode is useful

Cons

• –60 Hz only
• –Niche aspect ratio for video
• –Few competitors, so price is firm

BenQ built a monitor specifically for programmers and, unusually, it is not a gimmick. The 3:2 aspect ratio at 3840 by 2560 gives you 400 more vertical pixels than a 4K panel at the same width. Depending on font size, that is around fifteen extra lines of code on screen. The matte finish handles bright rooms well, and the “coding mode” is a tuned contrast and colour profile that reviewers say helps dark themes read clearly.

It is 60 Hz and the aspect ratio makes video letterboxed. If you watch films on your work monitor, that will annoy you. For writing code, the extra height is the reason to buy it.

#3 Best ultrawide

Dell UltraSharp U4025QW

Check price on Amazon

• 40-inch 5K2K, 5120 x 2160
• 120 Hz
• Thunderbolt 4, 140 W
• Curved IPS Black

Pros

• +Replaces two 27-inch monitors with no bezel in the middle
• +Same pixel density as a 27-inch 4K
• +Charges the laptop and docks everything

Cons

• –Expensive
• –Needs a deep desk
• –Window management needs a tiling tool

A 40-inch 5K2K ultrawide is exactly two 27-inch 4K monitors glued together, minus the bezel in the middle. It has the same pixel density, so text is just as sharp, plus 120 Hz and Thunderbolt 4 with 140 W. Editor on the left, browser and terminal on the right, with room to spare.

You need a deep desk, because the panel is wide and curved. You need a tiling window manager or at least a snapping tool, because dragging windows across this much space gets old. And you need the budget. For people who already run two monitors, it is a straight upgrade.

#4 Best for Mac users who want zero fuss

Apple Studio Display

Check price on Amazon

• 27-inch 5K, 218 ppi
• Thunderbolt 3, 96 W
• Excellent webcam, mics and speakers
• Nano-texture option

Pros

• +Sharpest text here, matches MacBook pixel density
• +Webcam and speakers replace three accessories
• +Aluminium build

Cons

• –60 Hz
• –Adjustable stand costs extra
• –No HDMI, Mac-centric

If you work on a Mac and you want the laptop screen and the external screen to look identical, the Studio Display does that. 218 ppi matches the MacBook exactly, so nothing changes size when you drag a window across. The webcam, microphones and speakers are good enough to retire three separate accessories.

It is 60 Hz, the height-adjustable stand is a paid upgrade, and connectivity is Thunderbolt only. On Windows it works but you lose brightness control and the camera features. Buy the nano-texture version if your office has a window behind you.

#5 Best value 4K

LG UltraFine 27-inch 4K

Check price on Amazon

• 27-inch 4K IPS
• USB-C with charging
• VESA mount
• HDR10

Pros

• +4K sharpness for a lot less money
• +USB-C single-cable setup
• +Reliable and widely available

Cons

• –60 Hz
• –Lower contrast than IPS Black
• –Fewer ports

Not everyone needs IPS Black and 120 Hz. LG’s UltraFine 4K gives you the same sharp 163 ppi text, USB-C with laptop charging, and a VESA mount, for a lot less than the Dell. Contrast is lower, so blacks are a bit grey in a dark room, and there are fewer ports.

For a second monitor, a home office on a budget, or a junior engineer’s first real setup, it is the right call.

On the road

None of these fits in a bag. For a second screen that does, see our portable monitors guide.

Two monitors or one big one?

Two 27-inch 4K monitors cost less than one 40-inch ultrawide and give you the same pixels. The ultrawide wins on the missing bezel and the single cable. Two monitors win on flexibility, because you can rotate one to portrait for a log viewer or a long file. Both setups have loyal followers.

The short version

• Just buy the good one: Dell U2725QE.
• You want the most lines of code on screen: BenQ RD280U.
• Replace your dual-monitor setup: Dell U4025QW.
• Mac, and you want it to feel like Apple built the desk: Studio Display.
• Sharp text without the premium: LG UltraFine 27-inch 4K.
