The Dell P2423D is a 24-inch, 1440p monitor meant for productivity use. Part of Dell's P series of productivity monitors, which includes larger models like the P2723D, it's similar to other 24-inch, 1440p monitors such as the Lenovo ThinkVision P24q-30 and the LG 24QP500-B. It has a higher resolution than most 24-inch monitors, so text and images appear sharper. Its compact size makes it a good option for dual and triple monitor setups, particularly if you rotate it vertically. Though it doesn't have many extra features, it does have four USB ports for attaching peripherals.

Our Verdict

4.9 PC Gaming

The Dell P2423D is bad for PC gaming, but it isn't designed for this. It's limited to a 60Hz refresh rate, and it doesn't have VRR support to reduce screen tearing. While it has low enough input lag for a responsive feel, motion is very blurry due to its poor response time.

Pros
Cons
  • Fast-moving objects look blurry.
  • No local dimming feature.
  • No HDR support.
  • Disappointing contrast.
2.6 Console Gaming

The Dell P2423D is terrible for console gaming. It can't display a 120Hz or 4k signal and doesn't support VRR or HDR. Though it has low input lag for a responsive enough feel, fast-moving objects look blurry due to its poor response time.

Pros
Cons
  • Fast-moving objects look blurry.
  • No local dimming feature.
  • No HDR support.
  • Disappointing contrast.
7.9 Office

The Dell P2423D is very good for office use. Its superb ergonomics allow you to adjust the screen to your optimal viewing position, and thanks to its wide viewing angles, you can easily share your work with colleagues. It also handles reflections well and gets bright enough to overcome most glare, though it struggles with very bright light sources. Lastly, it has a higher resolution display than most 24-inch monitors, so it has great text clarity.

Pros
  • Bright enough to fight glare in most environments.
  • Wide viewing angles.
  • Superb ergonomics.
  • Great text and image clarity.
  • Four USB-A ports.
Cons
  • Harder to see in very bright environments.
6.5 Editing

The Dell P2423D is okay for media creation. It has superb ergonomics, so you can easily place it in an ideal working position. It also has wide viewing angles, so it's easy to share your work with others. Though it has good accuracy before calibration, it doesn't support HDR, so you can't use it to edit HDR content. Additionally, deep blacks appear gray in a dark room, making it harder to see shadow details during editing.

Pros
  • Bright enough to fight glare in most environments.
  • Wide viewing angles.
  • Superb ergonomics.
  • Great text and image clarity.
  • Four USB-A ports.
Cons
  • No local dimming feature.
  • No HDR support.
  • Harder to see in very bright environments.
  • Disappointing contrast.
2.9 Brightness

The Dell P2423D has decent brightness in SDR, enough to fight glare in most situations, though it's harder to see in very bright environments. It also doesn't support HDR.

Pros
  • Bright enough to fight glare in most environments.
Cons
  • No HDR support.
  • Harder to see in very bright environments.
4.5 Response Time

The Dell P2423D has a terrible response time, and fast-moving objects look quite blurry.

Pros
Cons
  • Fast-moving objects look blurry.
2.3 HDR Picture

The Dell 24 Monitor P2423D doesn't support HDR.

6.1 SDR Picture

The Dell 24 Monitor P2423D has mediocre SDR picture quality. Its low contrast ratio makes blacks look gray next to bright highlights, and the screen looks cloudy when displaying a dark image.

Pros
Cons
  • Screen is cloudy when displaying a dark image.
  • Disappointing contrast.
8.0 Color Accuracy

The Dell 24 Monitor P2423D has good color accuracy. However, you need to calibrate it for the best accuracy as colors are oversaturated before calibration.

Pros
  • Good color accuracy before calibration.
Cons
  • 4.9 PC Gaming
  • 2.6 Console Gaming
  • 7.9 Office
  • 6.5 Editing

Differences Between Sizes And Variants

We tested the 24-inch Dell P2423D, which is part of Dell's series of productivity monitors, some of which are listed below. Most of these monitors are similar, but there are some differences. You can see the differences between the monitors below. The results in this review are only valid for the model we tested and aren't valid for the other monitors.

Model Code Size Resolution Refresh Rate USB-C
P2423D 24" 1440p  60Hz No
P2723D 27" 1440p 60Hz No
P2723DE 27" 1440p 60Hz Yes

Our unit was manufactured in February 2024; you can see the label here. It was tested with firmware M3C101.

Compared To Other Monitors

The Dell 24 Monitor P2423D is a great high-resolution 24-inch productivity monitor that works well on its own or in a multi-monitor setup. It displays much sharper text and images than most 24-inch monitors, and it has great viewing angles, so it's easy to share content from your screen with a coworker. However, it has some limitations. While it gets bright enough to overcome glare in most situations, it struggles with extremely bright light sources. It also doesn't have HDR support, so if viewing and editing this type of content is important, consider the AOC Q27G3XMN, which has outstanding HDR performance. It's also better at overcoming bright glare but has worse viewing angles, so it's not as good for sharing work with colleagues.

Also, see our recommendations for the best office monitors, the best monitors for dual setup, and the best 1440p monitors.

Dell S2721QS

The Dell P2423D and the Dell S2721QS are both budget-friendly office and productivity monitors. The S2721QS is the better monitor for most people, as it has a sharper display, is better at overcoming glare, and can view and edit HDR content. However, the P2423D is more compact, so you may prefer it if you have limited space or want a dual or triple monitor setup. The P2423D also has USB ports for connecting multiple peripherals to your computer with a single cable.

Dell S2722QC

The Dell P2423D and the Dell S2722QC are both designed for productivity work. The S2722QC is the better monitor for most people, as it can display content in HDR, is better at overcoming bright glare, and has a more detailed image. It also supports DisplayPort Alt mode with 65W of power delivery, so you can connect your laptop to display an image and charge it with the same cable. However, the P2423D is more compact, so you may prefer it if you have limited space or want a dual or triple monitor setup.

ASUS VG246H

The Dell P2423D and the ASUS VG246H are both 24-inch monitors that are well-suited to productivity work. The Dell is the better monitor as it has a higher resolution display for more detailed text and images and four USB ports to easily connect peripherals.

Dell UltraSharp U2520D

The Dell UltraSharp U2520D and the Dell P2423D are both 1440p productivity monitors. The U2520D is the better choice for most people, as it's better at fighting glare, is able to display HDR content, and has a USB-C hub with power delivery.

The monitor has good accuracy before calibration. It doesn't have a dedicated sRGB mode, and colors are oversaturated. Additionally, the white balance is mediocre, though the color temperature is fairly close to the 6500K target. Gamma follows the target curve well, though dark scenes are a bit too dark, and brighter scenes are slightly too bright.
