The Dell U3225QE is a premium 32-inch 4k productivity monitor. It competes with a number of other 32-inch office monitors, such as ASUS's ProArt PA329CRV and the BenQ PD3225U. The U3225QE is a substantial upgrade to the older Dell U3223QE, adding new features like a 120Hz refresh rate, improved connectivity options, VRR support, Thunderbolt 4 support, and more. In many ways, it's a smaller version of the Dell U4025QW, as both monitors are part of Dell's UltraSharp line and share many of the same features and capabilities, apart from the U4025QW's larger 40-inch screen.

Our Verdict

6.4 PC Gaming

The Dell U3225QE is mediocre for PC gaming. It displays a wide range of vivid colors, and the screen gets bright enough to overcome glare in HDR, though highlights don't pop. However, it has terrible local dimming and deep blacks appear somewhat gray. Additionally, it has bad motion handling despite its 120Hz refresh rate, so it's not well suited to fast-paced games. However, it could work well for slower-paced games such as turn-based strategy and text-heavy RPGs, where there isn't as much fast motion.

Pros
  • Displays a wide range of vivid colors in HDR.

  • Supports all VRR formats.

Cons
  • Fast-moving objects look blurry.

  • Terrible local dimming feature.

  • Highlights don't pop in HDR.

7.9 Console Gaming

The Dell U3225QE is good for certain types of console gaming. It displays any signal from the PS5 and PS5 Pro and Xbox Series X|S, including 120Hz signals. It also displays rich and vivid colors, and easily overcomes glare in HDR, though highlights don't pop. However, deep blacks appear somewhat gray in a dark room. Additionally, it has bad motion handling, so it's not well suited to playing fast-paced games.

Pros
  • Displays a wide range of vivid colors in HDR.

  • Supports VRR with PS5, PS5 Pro, and Xbox Series X|S

Cons
  • Fast-moving objects look blurry.

  • Terrible local dimming feature.

  • Highlights don't pop in HDR.

8.6 Office

The Dell U3225QE is amazing for office work. It has fantastic text clarity and ergonomics, so it's comfortable to work with for long intervals. It also gets bright enough to easily overcome glare, so it works well in any environment. Additionally, it has a lot of connectivity options, so you can use it as a USB hub, connect multiple extra monitors, or charge a laptop with up to 140W of power from the display. It also has a KVM switch, so you can switch between two different computers while using the same devices.

Pros
  • Easily overcomes glare.

  • Wide viewing angles.

  • Fantastic ergonomics.

  • Fantastic text and image clarity.

  • KVM switch and 140W power delivery over USB-C.

Pros
  • Easily overcomes glare.

  • Wide viewing angles.

  • Fantastic ergonomics.

  • Fantastic text and image clarity.

  • KVM switch and 140W power delivery over USB-C.

  • Displays a wide range of vivid colors in HDR.

Differences Between Sizes And Variants

We tested the 32-inch Dell U3225QE, which is one of several similar 32-inch models Dell offers in their UltraSharp series. It's also available in a smaller 27-inch size, but that version performs differently. You can see the major differences between these monitors below. These results are only valid for this model.

Our unit's label indicates it was manufactured in December 2024. It was tested with firmware M2T101.

Compared To Other Monitors

The Dell U3225QE is a premium 32-inch 4k productivity monitor. It delivers features not seen in most office monitors, such as multiple outputs to connect additional displays, 140W of power delivery over Thunderbolt 4, and a 120Hz refresh rate. It's a fantastic option not just for office work but also for editing, as it's quite accurate even before calibration, and it displays a wide range of colors vividly. It's an ideal choice if you're looking for a 32-inch productivity monitor and have a big budget. However, if you like all these features and want something even bigger, consider the Dell U4025QW, which has a very similar feature set but a larger 40-inch display. Additionally, if you want a great 4k display for productivity work but don't need this monitor's extra features and want to save some money, cheaper 32-inch displays, like the Dell U3223QE, provide the same text clarity and similar image quality at a much lower price if you can still find it available.

See our recommendations for the best 4k monitors, the best work monitors, and the best 32-inch monitors.

Dell U3223QE

The Dell U3223QE and the Dell U3225QE are both 32-inch productivity monitors. The U3225QE is the better choice if you can afford it, as it has a higher refresh rate for a more responsive feel, better connectivity, and better image quality. However, both display equally sharp text, and the U3223QE is a better choice if you have a more limited budget and it's available.

Dell U2725QE

The Dell U3225QE and the Dell U2725QE are extremely similar 4k office monitors. Both have nearly identical features and very similar performance. As a result, the U2725QE is a better option if you prefer a smaller display, whereas the U3225QE is a better option if you prefer a larger one.

Dell U2723QE

The Dell U2723QE and the Dell U3225QE are both UltraSharp productivity monitors. The U3225QE is the better monitor if you can afford it, as it overcomes bright glare much better, displays a wider range of colors, feels more responsive even for office use, and has far better connectivity options. However, the U2723QE is much more affordable, and you may prefer it if you like a smaller monitor.

Dell U4025QW

The Dell U4025QW and the Dell U3225QE are Dell UltraSharp productivity monitors. Both have very similar feature sets and performance, though the U3225QE gets brighter, so it's a better choice for a brighter room. If you prefer an extremely large monitor, the U4025QW is a better choice, as it has a 40-inch screen. If you prefer something a bit smaller, the U3225QE is a better option, as it has a smaller 32-inch screen.

Lenovo Legion Y32p-30

The Lenovo Legion Y32p-30 and the Dell U3225QE are both 32-inch monitors. The Dell is the better option if you plan to use your monitor for work, as it gets brighter, displays a wider range of colors, and has better connectivity. However, the Lenovo is a better option if you plan to game with the monitor, as fast-moving objects look much crisper.

The Dell U3225QE has a decent contrast ratio. It has better contrast than most IPS displays because of its enhanced IPS Black technology, but it's not much better than older IPS Black displays, and deep blacks still look somewhat gray in a dark room. Additionally, it has far worse contrast when local dimming is enabled.

The Dell U3225QE has terrible local dimming. It has eight large zones that light up as soon as any bright object is displayed in a given zone, including things like subtitles or bright lights on lampposts. Darker parts of dark scenes lose detail when this happens and appear gray instead of black. Additionally, the large zones are distracting when they turn on or off.

You can't turn off local dimming if you have HDR turned on in Smart HDR settings, and it only operates in HDR.

The HDR brightness is good. Though it gets bright enough to overcome glare, highlights don't pop. Additionally, smaller highlights are more muted. It follows the PQ EOTF curve well until it has a slow-roll off near peak brightness, so highlights don't get as bright as they could.

The accuracy before calibration is excellent in the 'sRGB' Color Space. Colors are only slightly oversaturated, and overall, color accuracy is great. However, the white balance is only fair. Gamma follows the target curve extremely well, and all parts of scenes have the correct brightness.

Locked-Out Settings

The 'sRGB' Color Space mode locks out the following settings:

  • RGB Settings
  • Color Temperature

If you want to access these settings, you need to use another mode like 'Custom Color,' though it's less accurate and has very oversaturated colors.

The reflection handling is good. The matte coating diffuses light well, though reflections can be a bit distracting if you're using it in a very bright environment, like opposite a sunny window.

This monitor's matte coating has minimal fuzziness compared to other matte finishes. That said, you may see a slightly-noticeable fine paper-like texture when displaying solid colors, white, or when viewed off-axis. However, this doesn't affect picture sharpness or contrast.

The Dell U3225QE has disappointing motion handling across its VRR range. No matter what Response Time setting you choose motion is blurry, though the 'Normal' Response Time looks better than 'Fast'. In fact, the CAD of 'Fast' is so high that it exceeds the limits of the graph. We've created an alternate graph at a different scale to illustrate how high the CAD gets.

The Dell U3225QE works well with macOS. If you're using a MacBook and close the lid, the windows shift to the Dell's screen. Opening the lid or waking the laptop up from sleep moves the windows back to their original position. HDR looks good, and VRR works well. Additionally, the KVM switch works well with macOS. Dell also has a guide to using their Display and Peripheral Manager software with macOS.

You can connect up to two additional monitors to the Dell. However, on macOS, you can only do this by connecting a second monitor to the Thunderbolt output and a third monitor to the DisplayPort output.

  1. Update: We’ve converted this review to Test Bench 1.2. This update builds on our previous ‘Suction’ test with a new ‘Airflow’ test that more accurately measures a vacuum’s ability to generate air movement. If you’d like to see an in-depth look at the reasoning and methodology behind this change, you can see our full changelog here..
