USB-C Monitor Made for Laptops

As a result of a rise in dwelling working and the restricted house that entails, smaller monitor designs are making one thing of a resurgence. The place as soon as bigger-is-better was as soon as the mantra, now concerns like blue-light safety, energy consumption and environment friendly use of house are given better weight in monitor decisions.

Dell, by no means one to disregard a growing alternative, has produced the trendy Dell UltraSharp 24 (U2421E) to handle this market. A USB-C Hub Monitor large enough for basic workplace work and ideal for many who use a laptop computer as their every day workhorse.

Did Dell get the combination of performance and efficiency proper with the U2421E, or may it have been higher?

Out of the field

Dell deserves a gold star for the packaging alone. The tray that holds the U2421E, its help arm and all of the cables makes use of pressure-formed cardboard and never that horrible, expanded foam so beloved by many monitor makers.

Not solely is that this higher for the setting, however this selection doesn’t coat the show with extreme quantities of static electrical energy that then appeal to all of the mud from the room inside hours.

Together with the show, you get a two part-support arm that may be assembled and hooked up to the display screen with out instruments and a wide selection of cables.

Gone is the period the place an included HDMI cable impressed us, however then that isn’t included. What’s are a DisplayPort cable, a Kind-A to Kind-C USB and a dual-ended USB Kind-C cable.

There have been additionally two energy cords in my field, one for the US and one for the UK. Dell is normally very attuned to native socket variations, so I’d count on at the very least one energy wire that matches the retailers in your house or workplace.

Getting the U2421E out of the field and assembled is remarkably simple, because the panel solely weighs 4kg, and becoming a member of it to the help is a tool-free operation.

The help arm and base are each plastic coated however have steel inner elements making them sturdy sufficient to help the show. Additionally they present loads of adjustment with 21 levels of tilt backwards and 5 levels ahead, 40 levels of swivel and 90 of pivot. The pivot, or twist when you want that phrase, is mixed with 15cm of vertical journey that allows the U2421E for use for portrait mode.

Different facets of this design that I like embrace an inner PSU, avoiding the annoying proprietary energy brick that’s normally the primary level of failure. Dell additionally resisted the urge to place a canopy over the inputs, making cabling remarkably simple when you use the pivoting function to enhance entry.

Options & Design

I’ve concluded that each one displays have the designer’s pondering embedded in them intrinsically. Presumably, as a begin level, every is given an archetypal buyer definition and the ensuing product represents a solution to that downside.

The thriller is that we by no means get to see the temporary and solely guess what it included based mostly on how the design ended up. On the coronary heart of the query answered by the U2421E is laptop computer use, particularly those who use one for each cell computing and within the workplace.

Subsequently, an important side of this design is its ‘hub’, which performs the identical position as a USB-C docking station.

Connecting requires a USB 3.2 Gen 2 USB-C port, ideally the charging port on the machine. With more and more highly effective laptops coming to market, providing 60W and even 85W may not be sufficient.

This one line can ship 90W of energy, enabling it to energy the machine in use and cost the battery concurrently.

However this connection additionally supplies for downstream USB connections to peripherals, like a mouse and keyboard, one other USB-C system with 15W of charging (a cellphone), RJ45 wired networking and can even carry the show information.

Through this single cable, the laptop computer shouldn’t be solely capable of recharge however linked to every thing it wants shortly and successfully, avoiding the necessity for a docking station or extra advanced wiring options.

However it’s also possible to join any computer systems which have the commonest video outputs. HDMI and DisplayPort are normal necessities and subsequently anticipated, however the inclusion of DisplayPort out is an odd possibility that we don’t typically see today.

Dell makes a twin Monitor arm, the MDA20, that two U2421E would possibly properly match. A single DisplayPort output could be linked to 1 after which chained to the second monitor by way of the DisplayPort out.

As neat an answer as that is perhaps, it solely works if the worth of two U2421E is lower than an ultrawide show that solely has a single connection, has no frames dividing the center of the picture and doesn’t require a twin monitor arm.

These economics don’t work, sadly, making this function considerably redundant.


The marketplace for this design evidently isn’t avid gamers, as that is an IPS know-how panel that may solely obtain 8ms refresh in regular mode or 5ms in ‘quick’ mode. However different limitations corresponding to the utmost 60Hz refresh and the shortage of variable sync underline that there was no intention to make this panel a multi-purpose resolution.

What IPS shows are good at is viewing angles and color gamut, and the U2421E ticks these containers at the very least on the paper specs.

Most flat displays made today have the identical ratio of 16:9, however the U2421E has a ratio of 16:10 and a decision of 1920 x 1200. That was a well-liked decision within the early days of LCD panels, however I’ve not seen many supporting it lately.

The benefit of this decision over extra conventionally 1080p, is that it leaves extra vertical room for the taskbar with out protecting up any 1080p content material being proven above it. The additional slice of display screen actual property could be helpful, though when you play a 1080p film in full-screen mode it would find yourself being relegated to black bars on the high and backside of the picture.

To keep away from predictable confusion, Dell positioned an orange plastic plug within the DP-out port, so customers wouldn’t insert a DisplayPort cable in there from the pc after which marvel why they obtained no image.

There’s additionally an irritating draw back to this function. Underneath the foundations of HDCP, ‘repeaters’ should not allowed as you is perhaps stealing that content material away. As dumb as this would possibly all appear in a streaming world, and it’s, some HDCP compliant functions might refuse to play with this display screen linked.

The on-screen menu is accessible with a button joystick on the again proper of the panel that’s extra intuitive than a line of buttons and sooner to make modifications. Primary pre-sets embrace Recreation, Film and Normal, and you may alter the color temperature, side ratio, enter color format and quite a few different options that relate to the USB hub.

Prime marks right here for ease of use and making stuff you would possibly typically change, like enter supply, faster to entry, however providing many changes deeper within the menu for those who want them.

One potential subject that I skilled is that this monitor seems as an audio system, and Home windows will usually make it the default output while you join it to the pc. That system is the audio jack for headphones, because it has no built-in audio system.

I point out this for many who would possibly marvel what occurred to sound after hooking the U2421E as much as a system.


Dell very kindly features a manufacturing facility generated color calibration report within the field, displaying how the monitor carried out earlier than it was shipped.

My pattern had three graphics that coated sRGB Delta E over the spectrum, Grey-Scale monitoring of color temperature and at last Gamma in opposition to brightness per cd/m2 (nits).

What’s odd is that on Dell’s graph, the U2421E failed to achieve the 350 nits quoted on the specs. Not that makers don’t exaggerate about their merchandise, however in my testing this design not solely reached that stage however exceeded it.

Peak brightness was 365 cd/m2, above the quoted 350cm/m2, and static distinction was 980:1, only a tiny bit in need of the 1000:1 that Dell quotes. The uniformity of brightness can also be good, with a median deviation of lower than 4% from the centre, though for no matter cause, it’s noticeably darker within the center high.

Nevertheless, while you push the brightness up from the 75% default setting on the OSD, you’re requested in case you are positive you wish to try this. If working above this stage is a matter, why present the choice to pick it?

Extra positively, the color illustration is sweet, however not at a stage that will impress these thought of to be colourists. The display screen managed 99% of sRGB and 83% of P3, however solely 76% of the AdobeRGB gamut. The spectrum weak spot is nearly completely on the inexperienced facet, with the blue and purple scope being first-rate.

For a business-orientated panel, these are stable numbers and will sway some to spend extra on this design for the prime quality of the illustration.


Dell initially gave a worth of £328 for the U2421E however the official web site exhibits an RRP of £408.59 within the UK. Nevertheless, each are slightly irrelevant and Dell now sells the monitor for £279.02. You may also get it from Amazon for £259.

It is a comparable story within the US the place pricing has gone from $469.99 to $374.99, with a $50 Dell Promo eGift card included.

These costs are extra enticing than the RRPs however there’s robust competitors on the market for comparable displays.

The Philips 243B1 is 1080p, comparable docking station options and prices simply £227.99 within the UK.

An virtually similar panel to that within the Dell seems within the HP Z24n G2, which additionally has the USB-C options and prices simply £222.97 within the UK, and within the USA, it may be purchased in pairs for $499, making it lower than $250 for every display screen.

It is perhaps less expensive now, however the U2421E nonetheless isn’t a reasonable possibility. Discover out what different choices you could have in our greatest monitor chart.


The U2421E has strengths but in addition a number of weaknesses.

On the plus facet, it seems to be skilled, and the help arm permits it to pivot and tilt extensively. It’s additionally obtained first rate color illustration with near 100% sRGB protection and 83% of the P3 color house.

The USB-C options are additionally a profitable enhancement as they might simply take away an costly USB-C docking station from a system buying funds. Nevertheless, I can’t settle for the notion that it makes financial sense to purchase two of those and chain them by way of DisplayPort, even whether it is technically potential.

It’s potential to supply an Ultrawide display screen for lower than the mixed price of two of those, and that hints on the important downside the U2421E fails to confront, price. A brief browsing session on many giant on-line retailers will reveal a number of comparable designs with a remarkably shut specification, and most are usually cheaper.

Whereas it doesn’t must match or higher the very least expensive alternate options, it must be nearer to them than it at the moment is to make this a worthwhile funding.
