Color Accuracy

The Dell U3223QE is a 32-inch, 4k office monitor. Part of Dell's UltraSharp lineup, it sits alongside the Dell U2723QE and has a lot of features and connectivity options. It has a USB hub with five USB-A ports and three USB-C ports, which you can use to connect your peripherals like a keyboard and mouse and control multiple sources with them, thanks to the KVM switch. It has other perks that help with connecting multiple devices, like DisplayPort Alt Mode, a DisplayPort output to daisy chain a second monitor, and even an Ethernet port that's useful if your laptop doesn't have one. On top of that, it uses IPS Black panel technology that delivers a higher contrast compared to traditional IPS panels for deeper blacks.

Our Verdict

Differences Between Sizes And Variants

We tested the 32-inch Dell U3223QE, which is part of the UltraSharp Series lineup that includes the Dell U2723QE. The results are only valid for the 32-inch variant. You can see the difference between the monitors below.

Model Size Resolution Aspect Ratio
U2723QE 27" 4k 16:9
U3223QE 32" 4k 16:9

Our unit of the Dell UltraSharp U3223QE was manufactured in February 2022; you can see the label here. These results are with firmware M3T104.

Compared To Other Monitors

The Dell UltraSharp U3223QE is a great office monitor that has a ton of features to help your workflow, like its daisy-chaining, KVM switch, and USB-C inputs. The 32-inch screen and 4k resolution are great for multitasking, and the fantastic ergonomics make it easy to place in an ideal position. However, it undersaturates colors and costs more than the Dell U2723QE, so it's only worth getting if need the bigger screen.

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

Dell U2723QE

The Dell U2723QE is essentially a smaller version of the Dell U3223QE, but there are a few differences. The U2723QE has a wider swivel range, making it easier to share your screen with someone. The U2723QE also looks better in HDR as it doesn't undersaturate colors like the U3223QE. Both have disappointing reflection handling, but reflections on the U3223QE result in a pink tint that the U2723QE doesn't have. Also, the U3223QE has better out-of-the-box accuracy because the white balance is better.

Dell U3219Q

The Dell U3223QE is a newer version of the Dell U3219Q with similar overall performance. There isn't too much difference in terms of picture quality, except the U3223QE displays a wider range of colors in HDR and has better out-of-the-box accuracy. The U3223QE also has an extra USB port compared to the U3219Q, and it has a KVM switch that allows you to control two devices with the same keyboard and mouse.

Dell G3223Q

The Dell U3223QE and the Dell G3223Q are different types of 4k, 32-inch monitors. The G3223Q is a gaming monitor with a much higher refresh rate, VRR support, and quick response times, while the U3223QE is an office monitor with much better ergonomics and a bigger selection of inputs. Besides the different features, they have similar picture quality, but the G3223Q has much better reflection handling.

Dell S2722QC

The Dell S2722QC and the Dell U3223QE are both good overall 4k monitors with a few differences. The U3223QE has a better selection of inputs as it has a USB hub with a KVM switch, and it supports daisy chaining, allowing you to easily connect a second display. It also has better ergonomics, as it allows for greater height adjustment. However, the S2722QC has much better reflection handling, and it's a bit more versatile for gaming because it has VRR support.

Gigabyte M32U

The Dell U3223QE and the Gigabyte M32U are different types of 4k monitors. The Dell is focused on office use with a USB hub with more inputs than the Gigabyte, although the Gigabyte offers the same features, like DisplayPort Alt Mode and a KVM switch. The Dell also has much better ergonomics as you can rotate it into portrait mode. However, the Gigabyte is focused on gaming as it has a 144Hz refresh rate with HDMI 2.1 bandwidth and VRR support, allowing you to play games at high framerates from PCs and consoles without issue.

Dell P3223DE

The Dell P3223DE and the Dell U3223QE are different types of 32-inch office monitors. The U3223QE has a much higher 4k resolution that delivers sharper text. While both have similar USB hubs, the U3223QE has two more USB-C ports and a KVM switch, allowing you to connect a keyboard and mouse and control two devices with them. The U3223QE also supports HDR, which the P3223DE doesn't, but the HDR experience isn't the best anyway. On the other hand, the P3223DE has much better reflection handling if you want to use it in a bright room.

ASUS ProArt Display PA279CRV

The Dell U3223QE and the ASUS ProArt Display PA279CRV are both 4k monitors aimed at content creators, with the Dell having a bigger screen. They have many of the same features and similar performance, but they have a few differences. The Dell uses a panel with IPS Black technology, resulting in higher contrast than the ASUS and making it the better choice to edit content in a dark environment. The ASUS is better for well-lit rooms because it has much better reflection handling. The ASUS is also better for editing content in HDR, as it has better color volume since colors are undersaturated on the Dell. However, the Dell has extra features, like a bigger USB hub and a KVM switch, making it easy to multitask.

Dell U3425WE

The Dell U3223QE and the Dell U3425WE are both productivity monitors in Dell's UltraSharp lineup. Choosing one over the other comes down to which size and resolution you prefer, but there are a few differences in features, too. The U3425WE is more useful if your laptop has Thunderbolt support because the monitor itself supports Thunderbolt 4, which the U3223QE doesn't. The U3425WE also has a higher 120Hz refresh rate for a slightly smoother feel and supports VRR, which is beneficial for casual gaming. On the other hand, unlike the U3425WE, the U3223QE supports HDR.

Apple Studio Display

The Dell U3223QE and the Apple Studio Display are both high-end monitors meant for different uses. The Apple monitor is geared towards people who own a Mac, as it has features you can only use with macOS, like its accurate sRGB mode. It has other features the Dell doesn't have, like a higher 5k resolution, a webcam, and a microphone. The Apple monitor also gets brighter and has much better reflection handling, which is ideal if you need to use it in a bright room. However, the Dell is more versatile if you don't work with just a Mac computer, as it has a larger USB hub, including a KVM switch, and a much more ergonomic stand. The Dell also supports HDR, unlike the Apple, but it under-saturates colors in HDR anyway.

LG 32UL950-W

The Dell U3223QE and the LG 32UL950-W are both 32-inch, 4k monitors with a few differences. The Dell has many more features, as it has a much larger USB hub, making it easier to connect multiple devices. They each have USB-C ports, and the Dell supports higher power delivery, but the LG supports Thunderbolt 3, which allows for higher bandwidth than the DisplayPort Alt Mode than the Dell. Besides that, the Dell is more versatile because it has much better ergonomics, and it's also better for photo editing because it has more accurate colors.

Samsung Smart Monitor M8 S32BM80

The Samsung Smart Monitor M8 S32BM80 and the Dell U3223QE are different types of 4k displays. The Samsung has a built-in smart interface meant to make it easy to stream your favorite content without a PC. It also performs better in dark rooms thanks to its higher contrast. However, the Dell is an office monitor with a bunch more inputs, including USB-A ports, making it easy to connect multiple devices and your mouse and keyboard. It also has much better out-of-the-box accuracy, and it displays a wider range of colors, making it a better choice for content creators.

The Dell U3223QE has a decent contrast ratio. It uses IPS Black technology that improves the contrast compared to traditional IPS panels, but while it delivers deeper blacks, blacks still look gray in the dark. The local dimming doesn't improve the contrast much with the checkerboard pattern because it turns on all the dimming zones.

This monitor has a local dimming feature that performs terribly. It only turns on in HDR; the video above is in the 'DisplayHDR 400' Smart HDR setting. It's edge-lit with eight vertical dimming zones, which are all on most of the time with real content, so it doesn't do much to improve the picture quality in dark scenes. It isn't aggressive at turning zones on and off when there are bright objects or subtitles on the screen, which helps reduce blooming but also fails to improve the contrast ratio. Luckily, the local dimming keeps details in dark scenes as there's no black crush, but overall, the feature isn't useful.

The HDR brightness is alright. It doesn't make small highlights pop at all and doesn't deliver a satisfying HDR experience. The EOTF doesn't follow the target PQ curve well either, as there's a slow roll-off until it reaches its peak brightness, so it doesn't let highlights get the brightest they can. These results are from setting the Smart HDR mode to 'DisplayHDR 400' with firmware M3T101, which has a slower PQ EOTF roll-off compared to previous firmware.

You can see an example here of what the U3223QE looks like in HDR compared to the Samsung QN90B QLED (left) and the LG G2 OLED (right). You can see how muted highlights are, and the test content uses a Murideo 'The Seven Generator' device.

The accuracy before calibration is fantastic. The sRGB mode limits colors to the sRGB color space very well, and the white balance is fantastic. Gamma follows the sRGB target well, but some darker scenes are slightly too bright. Luckily, the sRGB mode only locks the RGB settings, so you can still adjust other settings like the brightness. Other modes are less accurate, with oversaturated colors.

The Dell UltraSharp U3223QE has an excellent overall HDR color gamut. It has near-perfect coverage of the commonly-used DCI-P3 color space but has bad tone mapping and undersaturates colors. You can see an example of how undersaturated the colors are here. They don't look as vivid compared to the Samsung QN90B QLED (left) and the LG G2 OLED (right). The test content uses a Murideo 'The Seven Generator' device.

These results are with firmware M3T101, which has a slightly more limited color gamut compared to previous firmware, but it isn't a significant difference.

The reflection handling is disappointing. Glare from strong light sources is distracting, and even though it gets bright in SDR, it still isn't the best choice if you want to place it opposite a window. It also has a pink tint that's noticeable when comparing it to other monitors like the Dell U2723QE, but it isn't distracting during regular use.

The CAD at 60Hz is bad. There's noticeable blur and smearing with fast-moving objects, and using the 'Fast' overdrive setting results in inverse ghosting.

The standout feature is its massive USB hub. Most of the inputs are on the back, but there are two on the left underside, which are easier to access if you need to connect a mouse and keyboard. The right USB-C port on the back is an upstream port, which you need to use if you want to use the KVM switch.

The DisplayPort Out port lets you daisy chain a second monitor directly to this one. It sends a 4k @ 60Hz signal with 10-bit color depth without any problems to a second display if your graphics card supports Display Stream Compression (DSC). It also has an RJ45 Ethernet port, ideal if your laptop doesn't have an Ethernet port, and it works without issues.

The USB-C port on the back supports DisplayPort Alt Mode, allowing you to display an image from a compatible device and charge it at the same time. It's the only port that supports 90W power delivery, while the USB-C port underneath the left side is only 15W, and the other is an upstream port needed for the KVM switch to work.

If you use the USB-C port for daisy-chaining, you need to make sure you set USB-C Prioritization to 'High Resolution' so that you can get two monitors at 4k @ 60Hz with 8-bit color depth, but once you set it to 10-bit color depth, the signal is unstable. If you set USB-C Prioritization to 'High Data', both displays run at 30Hz.

Inputs
macOS Compatibility

This monitor works without any issue with macOS. The USB hub and Ethernet port work as intended, and if you're using a MacBook windows return to their original positions when waking up from sleep. If you try to daisy chain a second display, it just mirrors the first display with a MacBook connected.

The Dell U3223QE has a bunch of extra features to increase your productivity while working, including:

  • ComfortView Plus: Removes blue light to help reduce eye strain.
  • KVM Switch: Allows you to connect a keyboard and mouse to the monitor and control two sources with them.
  • Multi-Monitor Sync: Synchronizes multiple monitor's settings when daisy chaining via DisplayPort.
  • Multi-Stream Transport: Allows you to daisy chain via DisplayPort or USB-C.
  • Power Sync: Automatically turns the display on and off when connected to a Dell PC via USB-C.
  • USB-C Prioritization: Lets you change the setting between 'High Data Speed' for DisplayPort 1.2 bandwidth and USB 3.2 Gen 2 speed or 'High Resolution' for DisplayPort 1.4 bandwidth and USB 2.0 speed. Both settings work with 4k @ 60Hz signals if you have one monitor connected, but you need to set it to 'High Resolution' for daisy chaining if you want both to run at 60Hz.
