$2,399.99
The Dell Ultrasharp U4025QW is yet one more instance of how the Ultrasharp line has reworked over the previous 5 years. Once recognized principally for its picture high quality, Dell has lately positioned practically equal deal with connectivity and now, with the latest Ultrasharp screens, refresh fee. The result’s an enormous, sharp, and intensely costly monitor that performs fantastically in most conditions.
What are the Dell Ultrasharp U4025QW’s specs and options?
The U4025QW’s specs are uncommon. It has a 40-inch IPS Black show with a decision of 5,120 x 2,160 and a refresh fee of 120Hz. This is a novel mixture of specs that no different show can at present match.

But, wow, do you pay for it. The Dell U4025QW is priced at a sky-high $2,399.99. I anticipate that worth will come down considerably inside a number of months, and maybe even at launch (Dell tends to set costs excessive, then mark them down). But since I don’t but know the place the worth will settle, I can’t give Dell credit score for what may occur.

How is the Dell Ultrasharp U4025QW’s design?

binary remark
Matt Smith
The Ultrasharp U4025QW has a really clear goal; firms and rich residence workplace employees searching for 40 superb inches of extremely useful show actual property. Dell’s design is laser-focused on this demographic. It’s easy and silver, enticing but inoffensive, fashionable however basic.
It’s not thrilling. But it really works. That’s thanks not solely to the silver matte end, which seems good-looking in all kinds of desks and rooms, but additionally the high-quality plastic supplies. There’s not loads of flex right here and, the truth is, the monitor is probably a bit too heavy. Remember, carry together with your legs!

Matt Smith
The monitor additionally has a slight curve, although it’s so delicate that I anticipate some customers wouldn’t instantly discover it. I’m a card-carrying member of the flat ultrawide monitor membership (there are dozens of us!), however that is shut sufficient to flat that I by no means discovered the curve distracting.
Yet the U4025QW has one unlucky drawback. The stand isn’t nice. I anticipate it’s the identical because the stand shipped with different massive Ultrasharp screens (it definitely appears to be like similar), but it surely appears overtasked when paired with an enormous 40-inch ultrawide monitor.
I seen the show tends to wobble. This occurred not provided that I bumped my desk, which is regular, but additionally after I used the monitor’s joystick, and even brushed the show. This additionally makes the monitor tougher to regulate, as a result of it tends to barely give for a second earlier than elevating or decreasing. Dell ought to look into this and think about an improve.
Alternatively, a 100x100mm VESA mount is on the market for attaching the monitor to a third-party monitor stand or arm.
How is the Dell Ultrasharp U4025QW’s connectivity and menu?

The Dell U4025QW’s connectivity options.
Matt Smith
Each new Dell Ultrasharp monitor appears to up the ante on connectivity, and the U4025QW does it once more. It has an enormous vary of connectivity that spans every little thing from Thunderbolt to wired Ethernet.
Let’s begin with video connectivity. The monitor has two Thunderbolt ports, every of which assist DisplayPort 2.0 and can be utilized with a USB-C port that has DisplayPort Alternate Mode. One of those additionally delivers 140 watts of Power Delivery.
The Thunderbolt ports present entry to an array of downstream connectivity that features 5 USB-A ports and three USB-C ports. Two of those USB-C ports, and one USB-A port, are positioned in a pop-out hub that’s discovered on the show’s lower-left lip. The hub makes it straightforward to shortly join a peripheral you may solely join quickly, like a USB storage drive.
A 2.5G Ethernet port and three.5mm audio jack spherical out the choices. The Ethernet port is particularly helpful, since it may be used to offer a USB-C laptop computer or pill with wired web connectivity.
On the entire, the U4025QW’s connectivity is tough to match and certain the perfect purpose to purchase the monitor. If you prefer to, or have to, work with a number of computer systems, wish to simply dock and undock from a number of linked peripherals, or want so as to add wired Ethernet to a tool that doesn’t have it, the U4025QW can clear up your issues.

The Dell U4025QW’s menu system with an in depth variety of picture configuration choices.
Matt Smith
Dell’s menu system additionally deserves reward. A responsive joystick on the monitor’s lower-right flank is used to flip via well-labeled menus. The out there choices are in depth and embody: automated brightness, a number of colour modes (sRGB, BT.709, DCI-P3, and Display P3), a customized colour mode (with adjustment for achieve, offset, hue, and saturation), and a number of HDR modes. There’s additionally a KVM swap and a number of picture-in-picture and picture-by-picture modes. Color temperature management is on the market, as properly, and exactly targets particular numerical values (resembling 6500K).
Speakers are included, too. They’re not wonderful however present respectable worth and sound effective for much less advanced content material, like podcasts or most YouTube movies. Music and flicks will push the audio system to their limits, although, so headphones or exterior audio system are really helpful for leisure.
How is the Dell Ultrasharp U4025QW’s SDR picture high quality?
Image high quality isn’t essentially the Dell Ultrasharp U4025QW’s high precedence. A monitor like that is as a lot a hub and command middle as it’s a show, and it’s possible as many individuals will use it for spreadsheets or information analytics as video modifying. Still, a monitor with a price ticket this excessive must ship visuals which might be not less than higher than common, and the U4025QW succeeds.

Matt Smith
We begin off with brightness, the place the U4025QW delivers as much as 408 nits. That’s a really aggressive determine, because the graph exhibits, and it means the monitor will stay helpful in lots of conditions. Want to make use of it in a flowery nook workplace with a flooring to ceiling window? It ought to be effective. And it’s in fact greater than sufficient for any residence workplace.
Also, as a reminder, the U4025QW has a helpful automated brightness function that can regulate brightness routinely relying on ambient mild. This function contains three “brightness range” settings that may enable you tune the automated brightness adjustment to your desire. I like to recommend utilizing it, as a result of in my expertise most individuals don’t wish to trouble with fidgeting with brightness all through the day.

Matt Smith
The Dell U4025QW hits a good most distinction ratio of 2050:1 with show brightness set to 50 %. That’s a superb outcome and roughly doubles the distinction ratio of most IPS screens that shouldn’t have an IPS Black panel. Photos, films, and video games are displayed with an affordable sense of immersion and depth.
On the opposite hand, the U4025QW is dearer than many Mini-LED and OLED screens. Examples embody the Corsair Xeneon Flex and Samsung Odyssey G9. These gaming-focused alternate options lack the U4025QW’s connectivity, although, so that you’ll should determine which is extra vital to you.

Matt Smith
Next up is colour gamut, and right here the U4025QW posts wonderful outcomes. It has a colour gamut that spans 100% of sRGB, 96 % of DCI-P3, and 95 % of AdobeRGB. A handful of screens rating higher, however this stays a robust outcome that’s close to the highest of what’s out there from screens in 2024.

Matt Smith
Color accuracy can be robust, if not class-leading. The U4025QW’s colour accuracy is on par with many different screens and may look correct to most viewers. It additionally has a variety of colour changes, so it’s attainable to calibrate the colour to both enhance accuracy or suit your preferences.
Color temperature and gamma proceed the U4025QW’s streak of excellent outcomes. It hit a default colour temperature of 6600K, which is only a shade off the goal of 6500K, and offered an on-target gamma curve of two.2. This means the default picture wasn’t too cool or heat and that content material appears to be like about as luminous because it ought to. The monitor affords colour temperature adjustment to tweak that setting to your desire or wants, however gamma can’t be configured within the monitor’s menus.
Sharpness additionally cuts within the U4025QW’s favor. The monitor’s 5120×2160 decision isn’t exceptional (I reviewed a 5K ultrawide from LG all the way back in 2018), but it surely stays the utmost decision out there in an ultrawide (21:9 side ratio) show. It achieves a pixel density of 138 pixels per inch (ppi). That’s a bit lower than a 27-inch 4K monitor, which hits 163 ppi, but it surely’s excessive sufficient to make particular person pixels just about indistinguishable at a typical viewing distance of two-and-half to a few toes.
How is the Dell Ultrasharp U4025QW’s HDR picture high quality?
The Dell Ultrasharp U4025QW helps HDR and is VESA DisplayHDR 600 licensed. That’s good on paper, however HDR efficiency is mediocre.
Brightness isn’t the problem. The monitor hits a most HDR brightness of 635 nits, and its brightness stays secure even when your complete show is lit. That separates it from OLED screens, which cut back the brightness of their OLED panel when massive, shiny objects have to be proven.
However, the U4025SW lacks the distinction to make HDR work properly. It doesn’t have a dynamic backlight, so growing the brightness of any portion of the show additionally will increase the brightness of your complete display. That’s an issue when viewing a starry evening sky or a neon check in a cyberpunk alley. Areas of a scene that ought to be inky black will as a substitute be a hazy grey.
So, whereas HDR is supported and works okay, it’s removed from best. I don’t suggest the U4025QW if HDR is excessive in your record of priorities.
How is the Dell Ultrasharp U4025QW’s movement efficiency?
Surprisingly, the U4025QW’s movement efficiency is noteworthy. It supplies a refresh fee of as much as 120Hz. That’s not a report, in fact, however bear in mind: The monitor has a decision of 5120×2160. Delivering 120Hz at that decision is spectacular.
The monitor additionally helps Adaptive Sync although, like different current Dell Ultrasharp screens, the main points are a bit odd. It formally lists “support for VRR as specified in HDMI 2.1,” which would appear to recommend it solely features over HDMI. That’s not the case. AMD FreeSync functioned with out situation alongside my Radeon RX 7800 video card, even when linked over DisplayPort.
Motion readability is sweet, however not nice. Fast-moving objects present good element with solely minor movement blur and pleasing fluidity. But some effective particulars, like small textual content or a delicate texture sample, can be illegible or obscured. The movement readability on supply right here can’t maintain as much as the perfect screens for movement, like a 240Hz or 360Hz OLED monitor, but it surely’s ok for many 3D video games and supplies a delicate increase to perceived fluidity on the Windows desktop.
Is the Dell Ultrasharp U4025QW value it?
The Dell Ultrasharp U4025QW is a wonderful monitor for individuals who need a large show that may function the centerpiece in a posh setup that almost definitely contains a number of computer systems. It has an unimaginable array of ports that spans Thunderbolt, USB-C, as much as 140 watts of Power Delivery, and a pair of.5G Ethernet. That comes alongside nice picture high quality and affordable movement readability.
The U4025QW isn’t a good selection for HDR content material, nonetheless, and it suffers a stand that appears overmatched by the show’s dimension and weight. Pricing can be a priority. The retail MSRP of $2,399.99 is much larger than rivals just like the LG 40WP95C-W, which regularly retails underneath $1,400. Dell has a number of benefits over LG, however that’s an enormous worth hole.
Even so, the Dell Ultrasharp U4025QW has a objective. It’s an apparent choose for folks keen to pay for a flagship workplace and productiveness monitor with all of the bells and whistles and future-proof connectivity.
