Dell U2723QE 4K USB-C Monitor Review

The Dell U2723QE review searches we see most often come from people who already know exactly what they want: a 27-inch 4K monitor that charges a laptop over a single USB-C cable, switches between two machines with a KVM, and looks calm enough on the desk to not draw attention to itself on a Teams call. The U2723QE has been the safe default answer to that brief for almost three years, and a chunky run of price drops through 2025 — Dell UK is currently shipping it for around £549 against a £759 launch price — has pulled it firmly back into the conversation for any reader trying to build a serious home office without paying for an Apple Studio Display.

We bought ours in November 2025 and have used it as our main panel for six months across a 14-inch MacBook Pro, a Dell XPS 15, and a Windows mini-PC that lives behind the desk. This review is for UK readers who want the daily-driver verdict — not the spec-sheet recital — and who care about the questions Dell’s product page does not answer: how good is the IPS Black panel really, does the KVM work without driver headaches, and is it still the right pick now the LG 27UP850-W has dropped below £400.

Short version: yes, the Dell U2723QE is still the monitor we recommend for most UK home-office workers on a Mac or USB-C Windows laptop, provided you can find it under £600. The IPS Black panel and the dock are the two features that make the price make sense. We will tell you which of those features are essential, which are nice-to-have, and which two monitors we would buy instead at higher and lower budgets.

Who the Dell U2723QE is for (and who should look elsewhere)

We have spent enough time recommending this monitor to readers, family and friends to recognise the three buyer profiles it suits best. If you fit one of these, the U2723QE is almost certainly the right call. If you do not, we will point you to better picks below.

Best for: USB-C laptop owners who close the lid

The single biggest reason to buy this monitor instead of a £349 Dell S-series is the 90W USB-C dock built into the back. One cable from your laptop to the monitor delivers the picture, charges the laptop, runs the webcam, the keyboard, the mouse and the gigabit ethernet, and lets you close the lid and use the monitor as your only display. We have run a MacBook Pro 14 (M3 Pro) and a Dell XPS 15 9530 off the U2723QE for six months with no third-party dock, no USB-C hub, and no missing peripherals. For Apple Silicon users in particular this is the single feature that makes the price defensible.

Best for: anyone running two machines and tired of swapping cables

The built-in KVM is the second reason we keep recommending this panel. Plug a USB-C laptop into the USB-C port and a desktop into DisplayPort with the supplied USB-B uplink cable, and a single OSD shortcut (or a tiny Dell Display Manager utility on Windows) swaps your keyboard, mouse and webcam between the two machines while the picture follows. It is not as fast as a proper hardware KVM box and the switchover takes about two seconds, but it removes a £90 accessory from most home-office shopping lists.

Best for: long-document and spreadsheet work, not gaming

At 60 Hz the U2723QE is not a gaming panel. There is no FreeSync, no HDR worth the name (it is HDR 400, which we consider an OSD checkbox more than a feature), and motion clarity is firmly in the office-monitor bracket. What you get in return is a panel calibrated out of the box for sRGB and DCI-P3, with a deep IPS Black contrast ratio that makes long Word and PDF sessions noticeably less fatiguing. We measured a fresh unit at ΔE 1.6 average against the sRGB reference, which is rare at this price.

Skip if: your room is small or your desk is shallow

27 inches at 4K is a lot of monitor. The U2723QE is 611 × 525 × 200 mm with the stand, and the stand alone wants a desk depth of 220 mm before the screen begins. If your desk is 60 cm deep (most IKEA LINNMON, LAGKAPTEN and BEKANT tops) you can fit it, but the bottom edge of the screen ends up close to a 17-inch laptop sat in front of it. If you have a 45 cm or 50 cm rented-room desk, look at the 24-inch Dell U2422HE instead — same dock, smaller footprint, 1080p.

Skip if: you want 1440p sharpness without scaling

27-inch 4K means you will be running display scaling — 150% on Windows, 2x retina-style scaling on macOS — to make text legible. macOS handles this beautifully; Windows is markedly better than it was on Windows 10 but still occasionally drops a legacy app at the wrong size. If you do not want to think about scaling, a 27-inch 1440p panel like the LG 27UP850-W (1440p version) or the Dell P2723QE (1440p) is the simpler buy.

Build quality and design: the bit Dell quietly gets right

The U2723QE looks identical to the U2722DE that preceded it: matte-black plastic chassis, slim bezels on three sides, a thicker chin with a discreet silver Dell logo. Nobody will compliment you on it, which is exactly the point. After six months on our main desk it has picked up no marks, no scuffs and no creaks. The plastic on the rear is the slightly textured grade Dell uses on the higher Pxx series, not the glossier finish of the cheaper S-series, and it does not show fingerprints.

The stand is the part you will notice every day, and it is excellent. 150 mm of height adjustment means we can run the bottom edge of the screen at 8 cm above a 75 cm sit-stand desktop in seated mode, and raise it to 23 cm for standing without strain. Tilt is firm without being stiff, swivel is 30 degrees each way, and the pivot to portrait orientation is the smoothest we have used at this price — useful for coders, less so for the rest of us, but a nice signal that Dell still cares about the office market.

VESA 100 mounting is standard. If you have read our [link to Ergotron LX review], the LX clears the U2723QE easily; the Amazon Basics single-monitor arm we tested as the budget pick (£45) holds it but visibly sags 5 mm at full extension, so go with the LX if you can.

Picture quality: the IPS Black difference is real

Dell’s 2022 switch to the IPS Black panel from LG Display is what justifies most of the price premium over a £349 27-inch 4K. IPS Black roughly doubles the contrast of a standard IPS panel — Dell quotes 2000:1, our test unit measured 1850:1 — while keeping the wide viewing angles and colour accuracy that make IPS the right office choice. In practice this means blacks on a Teams background look like dark grey rather than the bluish-grey wash of a 1000:1 IPS, and white-on-black PDFs are noticeably more legible at lower brightness.

Colour out of the box is the U2723QE’s other quiet win. Every U2723QE ships with a factory calibration report tucked in the box, and Dell’s claim of ΔE<2 average held up on our unit (we measured 1.6 in sRGB, 1.9 in DCI-P3 using a Calibrite Display SL). If you do any colour work — photo editing for a side project, video for YouTube, design work in Figma — this is the cheapest professionally-calibrated panel we know of in the UK. The BenQ PD2725U is sharper for design work but is £300 more.

Brightness peaks at 400 nits in HDR mode, 350 nits in SDR. We run ours at 30% (about 170 nits) for office work — bright enough for a north-facing London room in May, comfortable for an eight-hour day. The matte anti-glare coating is medium-strength: not the heavy grain of older Dell U-series panels, not the near-glossy finish of an Apple display. Reflections from a window behind your desk are diffused, not eliminated.

Uniformity on our unit is good but not perfect. The top-left corner is about 7% darker than the centre at full brightness, which is invisible during normal use but shows on a white test pattern. This is well within the spec Dell publishes and we have seen worse on monitors twice the price.

The USB-C dock: why this monitor pays for itself

On a £550 monitor, the dock is the feature that makes the price calculation honest. A standalone Dell or Anker USB-C dock with 90W PD, ethernet, four USB-A ports and HDMI passthrough is £130–£180 in the UK. Building it into the back of the monitor saves a cable run, a power brick, and a flat patch of desk.

Concretely, our U2723QE has the following plugged in permanently:

USB-C upstream to the laptop (one cable, picture + 90 W power delivery)
Ethernet (RJ45 1 GbE — faster and more stable than the room’s Wi-Fi 6)
Logitech MX Keys S keyboard receiver in one rear USB-A port
Logitech MX Master 3S receiver in a second rear USB-A port
Logitech MX Brio 4K webcam in the chin-mounted USB-C downstream port
Anker PowerConf S3 speakerphone in a side USB-A port for easy unplugging

That is the entire home office on a single cable to the laptop. When we close the MacBook lid, picture and peripherals stay live; opening the lid brings the laptop screen back as a second display with no fuss. For a Mac user this is the closest thing to a Studio Display experience under £600 in the UK.

A note on the 90W power delivery: it will run a 13-inch or 14-inch MacBook Pro at full speed indefinitely, and a 15-inch or 16-inch MacBook Pro for any normal office task. If you are rendering video or compiling large projects on a 16-inch, you will see the battery slowly drain under load — 90 W is not quite enough to keep up with peak power draw. For everything short of that, it is plenty.

The KVM: the feature people undersell

We did not buy the U2723QE for the KVM. We have come to use it every day. With one machine on USB-C and a second on DisplayPort plus a USB-B uplink cable (Dell supplies one in the box), pressing the OSD joystick down twice from idle swaps the keyboard, mouse, ethernet and webcam between the two machines in about two seconds. The picture follows automatically.

On Windows, Dell Display Manager lets you bind the KVM swap to a keyboard shortcut and remember which USB peripherals belong to which input. On macOS, you are limited to the OSD method, which is mildly less elegant but works perfectly with no driver install. We have run the KVM between a Windows mini-PC and a MacBook Pro for six months and have not once had it forget which keyboard belongs where.

There is one gotcha: the USB-C downstream port (the chin-mounted port we use for the webcam) does not switch with the KVM by default — it stays bound to whichever input is currently active. This is fine for most peripherals but means a USB-C peripheral that you want to follow the laptop specifically needs to be plugged into a different rear USB-A port via a small adapter.

Daily-driver verdict after six months

After 26 weeks of daily use the U2723QE has logged about 1,800 hours of on-time on our test unit, with no dead pixels, no backlight bleed worth mentioning, and zero hardware faults. Power draw at our typical settings (30% brightness, USB-C dock active, ethernet in use) sits around 38 W as measured at the wall — sensible for a 4K dock-monitor combo. Brightness has not measurably drifted; colour accuracy is within 0.2 ΔE of where we measured it on day one.

Two small things have annoyed us. First, the OSD joystick has a slightly cheap click feel for a £550 monitor — functional, but not the satisfying action of an LG UltraFine. Second, the speakers — sorry, there are no speakers. Dell sells a £25 SB522A soundbar that clips to the bottom bezel; it is fine for podcasts and Teams calls and we recommend it if you do not already have desk audio. We use the Anker PowerConf S3 plugged into the dock instead.

Nothing else has surfaced over six months. The U2723QE has done the one thing a home-office monitor needs to do: it has stopped being interesting. It is the screen we forget about, which is the highest praise we have to give a monitor on this site.

Dell U2723QE vs the alternatives

Three monitors come up in every Dell U2723QE comparison thread we have read. Here is how we would actually choose between them after testing all three.

Monitor	Price (UK, May 2026)	Best for	Trade-off
Dell U2723QE	£549	USB-C dock, KVM, colour accuracy	Premium for the dock and IPS Black panel
LG 27UP850-W	£379	Single-machine 4K USB-C on a budget	96 W PD but no KVM, lighter stand, no IPS Black
Apple Studio Display	£1,499	Mac-only users who want the matching finish and built-in speakers	Three times the price and no USB-C charging passthrough for anything but a Mac
Dell U2422HE	£429	Small desks (24-inch), still has the dock and KVM	1080p, not 4K — softer text on a small panel

vs LG 27UP850-W

The LG is the most common alternative we get asked about, and at £379 it is a genuinely strong panel. The trade-offs are real, though: no IPS Black contrast (you get a typical 1000:1 IPS), no KVM at all, a stand we found less stable, and a slightly worse out-of-box calibration that needs a profile to match what the Dell gives you in the box. If you only have one machine and one cable, and your budget is tight, the LG is the right buy. We covered it in detail in our [link to LG 27UP850-W review]. If you have two machines, or any colour-critical work, pay the £170 difference for the Dell.

vs Apple Studio Display

The Studio Display is a beautiful monitor and a fundamentally different product. It has built-in speakers that genuinely sound good, a 1080p webcam built into the bezel, and a 5K resolution that gives you Retina text without scaling tricks. It also costs £1,499, does not have a KVM, does not charge non-Apple laptops as cleanly, and is anchored to the Apple ecosystem. If you live entirely in macOS and your laptop is the only computer you own, it is the better experience. If you have any Windows or Linux machine in the mix, the U2723QE is the smarter buy and the £950 saving will cover most of a Herman Miller Aeron.

vs Dell U2422HE

The 24-inch U2422HE is the U2723QE’s smaller, cheaper sibling. Same chassis, same dock, same KVM, same stand quality — but 1080p at 24 inches instead of 4K at 27. We recommend it specifically for rental-room desks under 60 cm deep, where a 27-inch panel feels too dominant. At 24 inches, 1080p is sharp enough that you do not miss the pixels.

Where to buy in the UK (and what to pay)

At time of writing in May 2026, the cheapest legitimate UK source for the U2723QE is Dell.com’s own outlet, where refurbished units (typically returned within 30 days and re-tested) sit at £499 with the full three-year exchange warranty. We recommend the outlet route — we bought ours new in November 2025, but the outlet stock we have inspected for friends has been indistinguishable from new and Dell’s on-site swap warranty is excellent.

On Amazon UK the price oscillates between £569 and £619 with occasional flash sales to £539. Set a price alert; the £549 mark is the buy point we tell readers to wait for. [Affiliate link to Dell U2723QE on Amazon UK].

John Lewis carries the U2723QE for £649 with their 2-year guarantee bundled in. That is the most expensive route, but worth knowing about if you specifically want UK high-street warranty cover.

Verdict: still the right pick for the home office that has to last

Three years after launch, the Dell U2723QE remains the monitor we recommend most often for serious UK home-office work. It is not the cheapest 4K USB-C panel, it is not the highest resolution, and it is not the prettiest. What it is, after six months of daily use, is the quietly competent screen that solves the most expensive problems in a home office — the dock, the KVM, the colour accuracy, the contrast — at a price that has finally fallen into a bracket that makes sense.

If you want a 4K monitor that will still be the right monitor on your desk in 2030, and you can stretch the budget to £549, this is the one we would buy ourselves. Again. We did.
