The Dell U3225QE is a premium 32-inch 4k productivity monitor. It competes with a number of other 32-inch office monitors, such as the ASUS ProArt PA329CRV and the BenQ PD3225U, and it's higher-end than the Dell S3225QS. 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.

How We Test Monitors

We buy and test more than 30 monitors each year, with units that we buy completely on our own, without any cherry-picked units or samples. We put a lot into each unbiased, straight-to-the-point review, and there's a whole process from purchasing to publishing, involving multiple teams and people. We do more than just use the monitor for a week; we use specialized and custom tools to measure various aspects with objective data-based results. We also consider multiple factors before making any recommendations, including the monitor's cost, its performance against the competition, and whether or not it's easy to find.

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.

8.4
Office 

The Dell U3225QE is impressive 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 overcome most glare, so it works well in most environments, but reflections from bright sources are distracting. 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
  • Overcomes most glare.

    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.

    Model Size Resolution Panel Type Refresh Rate Power Delivery
    U3225QE 32" 4k Enhanced IPS Black 120Hz 140W
    U3224KB 32" 6k IPS Black 60Hz 140W

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

    Popular Monitor Comparisons

    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.

    BenQ PD3225U

    The Dell U3225QE and the BenQ PD3225U are both 32-inch 4k productivity and editing monitors. The Dell is the better option for most people, as it has a higher, more responsive refresh rate, gets much brighter, displays colors more vividly and accurately, and has better connectivity. However, the BenQ has some unique features. If you want to use its HotKey Puck for quick settings adjustments or its dedicated software for editors, you may prefer it.

    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 S3225QC

    The Dell U3225QE and the Dell S3225QC are 32-inch, 4k, 120Hz monitors from different lineups. The U3225QE is part of the high-end UltraSharp lineup, and it's equipped with additional features, including a larger USB hub, Thunderbolt 4 support, and a KVM switch. This makes it the better choice if you need an all-in-one monitor for connecting different devices. Despite being a lower-end model, the S3225QC boasts better picture quality thanks to its QD-OLED panel, which displays deep blacks, bright colors, and vivid highlights. The S3225QC is also better suited for gaming, as it offers superior motion handling.

    While the stand allows a bit of wobble in the display, this is expected with a monitor of this size, and it recovers quickly when bumped. Additionally, the monitor is stable at its maximum height. The thickness measurement is taken with the monitor at its lowest height. At its highest height, it's 6.3 inches (16.0 cm) thick.

    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, and blacks aren't as deep as on an OLED monitor, like the Dell S3225QC.

    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.

    • Smart HDR: DisplayHDR 600

    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 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 refresh rate compliance is awful. Its slow response time means that it can't make full color transitions between frames, so motion looks blurry.

    The CAD at the maximum refresh rate of 120Hz is disappointing, and you can see some blur even when scrolling quickly through documents and web pages. The 'Normal' Response Time setting with VRR off has the lowest CAD with very little overshoot. However, the CAD with VRR on is very similar, and you may not be able to see the difference, as the heatmaps and pictures in the table above indicate.

    This monitor has a large number of ports, including both upstream and downstream Thunderbolt 4 ports, a USB-C upstream port for the KVM switch, and two USB-C downstream ports. These ports and the KVM switch allow you to connect a large number of devices to the monitor and switch them between two different computers. For more information on these ports, see page 13 of the user's guide.

    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.
