Best Prices Today: Dell Ultrasharp U3225QE

Dell is on a bit of a tear with its Ultrasharp monitor line. In 2022 it released the U3223QE, the first monitor with a new IPS Black panel that improves contrast over prior IPS displays. That was followed by the U2724DE, an IPS Black office monitor with a 1440p 120Hz panel and extensive connectivity including Thunderbolt 4 and Ethernet. Now, the Dell U3225QE is first to market with a new 4K 120Hz IPS Black panel—and, as icing on the cake, it provides up to 140 watts of USB Power Delivery.

Dell Ultrasharp U3225QE specs and features

The Dell Ultrasharp U3225QE’s headline feature is the IPS Black panel. Dell says it’s the latest generation of IPS Black and quotes a contrast ratio of 3000:1, an improvement over the prior panel’s quoted contrast of 2000:1. It’s also a 31.5-inch 4K panel with a refresh rate of 120Hz. Prior IPS Black panels were available at 4K 60Hz or 1440p 120Hz.

However, the IPS Black panel is only half the story. The other half is connectivity, as the U3225QE has Thunderbolt, USB-C, and Ethernet, as well as USB Power Delivery up to 140 watts. It supports daisy-chain display connections and packs a total of six USB-A connections. That’s a lot of ports!

The monitor debuts with a retail price of $949.99. Although expensive, it’s in line with other flagship 32-inch 4K office and productivity monitors with Thunderbolt connectivity. At the time of this review, HP’s Series 7 Pro is $879.99, BenQ’s PD3225U is $999.99, and Dell’s older U3223QE (the U3225QE’s direct predecessor) is $669.99.

There’s also a 27-inch version of this monitor called the U2725QE. It has the same display panel technology, resolution, refresh rate, connectivity, and is roughly similar in design. It will retail at $699.99. While I tested the 32-inch model, I expect this review to be representative of the 27-inch model, too.

Dell Ultrasharp U3225QE design

The Dell Ultrasharp U3225QE doesn’t take the company’s design in a new direction, but that’s to its advantage. Ultrasharp monitors have settled on a professional look that pairs slim black bezels up front with a simple silver plastic around back. It’s not fancy, but it does the job and provides a premium feel (though it’s not as alluring as Samsung’s recent Odyssey OLED line).

It’s a similar story with the ergonomic stand, which adjusts for height, tilt, swivel, and can pivot 90 degrees into portrait orientation. The stand is stable, yet the base is small, which minimizes its footprint on your desk. A 100x100mm VESA mount is available for use with a third-party monitor stand or arm.

A small hole in the stand provides cable management. It’s good enough for a few connections, but if you plan to fill every port on the monitor, you’ll likely find that not all cables can fit through it simultaneously.

Dell Ultrasharp U3225QE connectivity

Connectivity is important for any monitor, but for the Dell Ultrasharp U3225QE, it’s make-or-break. Fortunately, the monitor doesn’t cut any corners.

Video inputs include one HDMI, one DisplayPort, and two Thunderbolt 4 / USB-C ports, all of which support video input. That’s a total of five video inputs. All video inputs support the monitor’s maximum refresh rate and resolution, too.

The Thunderbolt 4 / USB-C ports can handle data, and one of these ports provides up to 140 watts of USB Power Delivery. That’s more than most competitors, which typically offer 90 to 100 watts of Power Delivery: The HP Omen Transcend 32 is the only alternative we’ve yet reviewed to offer 140 watts of Power Delivery. Upping the maximum to 140 watts means the U3225QE can deliver enough power to handle Windows laptops with entry-level discrete graphics.

There’s a second DisplayPort, as well, which supports daisy-chain connections. That means you can input video to the U3225QE and then output from it to a second monitor. It’s helpful if you’re connecting a laptop with limited video-out connectivity, since you only need one video port to connect two monitors. There’s a Thunderbolt 4 downstream port too, and it also supports daisy-chain connections.

The Thunderbolt 4 / USB-C ports pass data to four downstream USB-A ports, each of which provides data rates up to 10Gbps. That’s another connectivity advantage, as data rates of 5Gbps are more common (although it should be noted that you won’t see 10Gbps if transferring data over all the USB-A ports simultaneously). KVM switch functionality is included, too, to help users quickly switch between two connected PCs.

A pop-out hub on the monitor’s lower-left bezel provides quick access to two USB-C ports with up to 15 watts of Power Delivery, as well as a USB-A port. This is handy if you want to transfer data with a thumb drive or charge your smartphone. The USB-C hub feels a bit cheap, however, because of its plastic construction. Dell should consider adding some metal to this portion of the display since users will frequently touch it.

The U3225QE’s long list of connectivity ends with 2.5Gbps Ethernet, another uncommon feature. Most modern Windows laptops with USB-C lack an Ethernet port, so having one built into the monitor is useful. A 3.5mm audio-out jack rounds out the connectivity.

A few competitors offer some similar options. The HP Omen Transcend 32 has 140 watts of USB Power Delivery, while the BenQ PD3226G provides Thunderbolt 4 with multiple USB-C and USB-A downstream ports. But the U3225QE’s combination of Thunderbolt 4, USB-C with 140 watts of Power Delivery, and 2.5Gbps Ethernet puts it ahead of the pack.

The U3225QE has a total of five video inputs — all of which support the monitor’s maximum refresh rate and resolution.

Dell Ultrasharp U3225QE features

The Dell Ultrasharp U3225QE’s extensive connectivity is flanked by several features that could prove useful in a home office. It’s a flicker-free panel (meaning it doesn’t use PWM to manage brightness) which, though not uncommon, is appreciated. More unusual is the monitor’s ambient light sensor, which can automatically adjust brightness based on the ambient brightness of your room. It can help reduce eyestrain by ensuring the monitor isn’t overly bright.

Users can control the monitor’s settings with a joystick tucked around the right side of the monitor. Dell’s on-screen menus are much larger than most competitors, which makes them easier to read. The image quality options include adjustments like color temperature, hue, and saturation, as well as preset modes for sRGB, DCI-P3, and AdobeRGB.

Options can also be changed with Dell’s Display and Peripheral Manager (DDPM), which has received an update. DDPM 2.0 has a more streamlined interface and a ribbon-like quick menu that keeps common options close at hand.

One feature you won’t find, though, is built-in speakers. Their absence is a bit unusual, as office monitors often provide a pair of 2-watt speakers, but Dell Ultrasharp monitors typically skip them. The lack of speakers isn’t a dealbreaker, as monitor speakers are usually quite bad, but something to keep in mind.

Dell Ultrasharp U3225QE SDR image quality

SDR image quality is critical for any monitor but especially important for an office and productivity monitor like the Dell Ultrasharp U3225QE. Most productivity apps don’t even support HDR. To achieve solid SDR, the U3225QE calls on a new IPS Black panel that promises even better contrast than before.

First up, however, is brightness. Here the U3225QE reached a maximum sustained SDR brightness of 469 nits. While not the highest number, that’s an excellent result and translates to an ultra-bright image at the monitor’s maximum brightness setting.

A brightness of 469 nits is far too high in most settings. But if you need a monitor that will look bright in a sunlit room, or in a starkly lit corporate bullpen, the U3225QE can do the job. It also has an anti-glare coat. It’s effective, but I’d call it more of a semi-gloss rather than matte finish.

Dell says the U3225QE has the latest IPS Black panel technology with a quoted contrast ratio of up to 3000:1. I measured a contrast ratio of 2900:1 with the monitor at 50 percent of its maximum brightness.

As the graph shows, that’s an excellent result. The LG MyView, the only monitor on the graph with a conventional IPS panel, reaches a mere fraction of the U3225QE’s contrast. The other monitors on the graph, all of which have an older IPS Black panel, are closer to the U3225QE but still notably behind.

The enhanced contrast ratio provides a pleasant, immersive quality to the image. Dark images can still suffer “IPS glow,” a hazy look caused by the monitor backlight, but it’s certainly minimized compared to other IPS monitors.

The U3225QE also did well in color gamut. It produced 100 percent of sRGB, 98 percent of DCI-P3, and 92 percent of AdobeRGB. These are excellent results that should please most creative professionals. The monitor is well-suited to editing videos, photos, and digital art.

However, the U3225QE does find itself against strong competitors. The Asus ProArt 5K and BenQ PD2730S 5K provide better coverage of DCI-P3, though they’re a tad weaker in AdobeRGB. And while I didn’t include any QD-OLED monitors on the graph, as they’re not direct competitors, they tend to provide better AdobeRGB coverage. The U3225QE’s color gamut is great but typical for a high-end monitor.

The U3225QE does well in color accuracy, where it delivers the lowest average color error among close competitors. That’s quite a compliment, as most monitors in this category already focus on tight color accuracy. Results like this indicate an exceptionally lifelike image that even the most critical viewers will appreciate.

The U3225QE’s strong color accuracy was thrown slightly askew by its color temperature and gamma performance which, although good, didn’t match its top-tier color accuracy. I measured a default gamma of 2.1, which means content is a bit brighter than ideal. Color temperature, meanwhile, came in at 6300K, which is warmer than the target of 6500K. These are small differences, though, and can be altered with the monitor’s settings.

Sharpness is good. The U3225QE’s 31.5-inch 4K panel provides a pixel density of about 140 pixels per inch and looks detailed in a wide range of content.

However, monitors with a higher pixel density are more common than they used to be. Asus’ and BenQ’s 27-inch 5K monitor both pack 217 pixels per inch, which is over 50 percent better than the U3225QE. Those monitors are smaller, of course…but with a pixel density that high, merely shoving a 27-inch 5K monitor a few inches closer to your face (such that it looks as large as a 32-inch monitor) is valid and will still result in better perceived sharpness than a 32-inch 4K monitor.

In summary, the U3225QE’s SDR image quality is excellent but not exceptional. It scores well by most metrics but often finds itself matched or beaten by price-competitive monitors. The new wave of 27-inch 5K monitors are an especially alluring alternative if sharpness and color performance are important to you, though they’re stuck at a 60Hz refresh rate.

Dell’s new IPS Black panel scores its biggest win in contrast. That will make the U3225QE’s more immersive image preferable if you want to use the monitor in a wider range of content, from productivity apps to movies and games. 

Dell Ultrasharp U3225QE HDR image quality

While likely to be used in SDR, the Dell Ultrasharp U3225QE supports HDR and is VESA DisplayHDR 600 certified. That’s a higher level of certification than most productivity and office monitors, which typically have DisplayHDR 400 certification.

However, the U3225QE’s added brightness doesn’t make for a great HDR experience. This is mostly due to the monitor’s contrast and the way the backlight system works.

The U3225QE has a conventional LED backlight which, unlike Mini-LED backlights, is not split up into dozens or hundreds of zones. Because of that, the U3225QE can’t display a very bright object in one corner of the display without elevating the brightness of the entire display surface. That’s a problem for high-contrast HDR scenes, and it results in a flat, dull look.

That’s not to say the U3225QE is hopeless, however. HDR support is useful if you need to work on HDR content, such as HDR video, and want to preview it on your display. Also, while the HDR experience isn’t good, it does have an edge against competitors with lower HDR brightness, such as the Philips Creator Series 27.

Dell Ultrasharp U3225QE motion performance

Dell upgraded some of its Ultrasharp displays, such as the Dell U2724DE, to a refresh rate of 120Hz about one year ago—but those displays had 1440p resolution. The U3225QE brings 4K with 120Hz, so there’s no need to choose between refresh rate and motion performance.

With that said, the monitor world is moving quicker on refresh rate, and your opinion of the U3225QE’s refresh rate will depend on your perspective. If you’re a professional used to a 60Hz monitor—which, to this day, remains an extremely common refresh rate for the category—the U3225QE will knock your socks off. Text is more readable in motion and Windows feels more responsive.

But if you’ve viewed a lot of 240Hz or 360Hz OLED monitors lately, the U3225QE might still disappoint. Motion clarity is nowhere near what you’ll experience from a 4K OLED gaming monitor like the Acer Predator X32 X3 or HP Omen Transcend 32. Fast-paced games look reasonably clear on the U3225QE, but fine details (like a name or spell effect above a fast-moving enemy) can be hard to make out.

Still, I applaud Dell’s continued pursuit of higher refresh rates in Ultrasharp monitors. It’s an edge over competitors still stuck on 60Hz. It also makes Dell’s monitors more appealing if you want a single monitor to handle Microsoft Word while you’re clocked in and Marvel Rivals after you clock out.

Should you buy the Dell Ultrasharp U3225QE?

The Dell Ultrasharp U3225QE continues the company’s leadership in professional productivity and office monitors. Compared to its peers, the U3225QE has a slight edge in image quality and a significant advantage in connectivity thanks in no small part to the inclusion of Thunderbolt 4 with 140 watts of Power Delivery. The U3225QE also provides 4K resolution with a 120Hz refresh rate, something virtually unheard of for a productivity and office monitor.

Pricing is also in the U3225QE’s favor. The monitor’s retail MSRP of $949.99 is expensive, but this is a flagship monitor with a combination of features you’re not going to find elsewhere. Competitive monitors, like the BenQ PD3225U and the Asus ProArt PA329CV, typically lack several of the U3225QE’s features, like the 120Hz refresh rate, Thunderbolt 4, and Ethernet. That makes the U3225QE an easy recommendation if you want a flagship office and productivity monitor.
