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.
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.

Popular Monitor Comparisons
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.
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.
The Dell P2423D and the Dell P2425H are both 24-inch productivity monitors. The two monitors are very similar, and the P2425H is a good option if you don't need the higher resolution or brighter screen of the P2423D. The P2425H also has a more responsive-feeling 100Hz refresh rate, though its response time isn't fast enough for games with lots of motion.
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 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.
Test Results
The monitor has a straightforward, office-oriented aesthetic. While the monitor is black, the square-based stand is silver.
The build quality is great. While the back of the monitor does flex under pressure, there's no issue with bezel uniformity.
The ergonomics are superb. You can easily adjust it to your preferred height or share your screen with someone next to you. It also rotates, so you can easily use it in a horizontal or vertical position. The stand features a cutout for cable management.
The monitor wobbles on its stand if you shake the desk or screen, though the stand holds the monitor in position well when you swivel it or adjust its height or tilt position.
There's a joystick at the rear of the monitor to control the on-screen display, as well as a power button.
The monitor has disappointing contrast. As a result, deep blacks appear gray in darker rooms, and the monitor has no local dimming feature to improve the contrast further.
Though this monitor doesn't have local dimming, we still film these videos so you can compare the backlight performance with a monitor that has local dimming.
The SDR brightness is decent. It gets bright enough to overcome glare in most environments, though it's more difficult to see content in extremely bright environments. These results are from the 'Custom Color' Preset Modes after calibration with the Brightness at max.
This monitor doesn't support HDR.
The horizontal viewing angle is very good. The image remains consistent from the sides, and you can easily share your screen with someone else.
The monitor has a good vertical viewing angle. The image remains consistent if you stand up and look down at the monitor.
The monitor has great gray uniformity. The outside of the screen is a bit darker, but there's very little dirty screen effect (DSE) in the center of the screen.
The monitor has poor black uniformity. There's significant backlight bleed along the edges of the screen, and cloudiness throughout the screen. Unfortunately, there's no local dimming feature to improve black uniformity.
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.
The accuracy after calibration is fantastic, and you won't notice any inaccuracies.
The SDR color gamut is fantastic, and the monitor has incredible coverage of the sRGB color space. However, it has more limited coverage of the Adobe RGB color space sometimes used in photo editing, and it doesn't display several colors accurately in that color space.
This monitor doesn't support HDR.
This monitor doesn't support HDR.
The text clarity is great. Enabling Windows ClearType (top photo) improves the boldness of letters. These photos are in Windows 10, and you can also see them in Windows 11 with ClearType on and with ClearType off.
The reflection handling is good. You can see the monitor in most environments, as its matte coating effectively reduces glare.
The monitor displays areas of similar color well, though a small amount of banding is visible in darker shades.
This monitor doesn't support variable refresh rate technology.
Although this monitor doesn't support VRR technology, we still measure the CAD at 60Hz, so you can compare it to a monitor with VRR support. The CAD is so high that the 'Fast' overdrive setting passes the limits of the chart. You can see an alternative chart here.
The refresh rate compliance is terrible, as its response time isn't fast enough to make full-color transitions before the monitor draws the next frame.
| Overdrive Mode | CAD Heatmap | RT Chart | Pursuit Photo |
| Normal | Heatmap | Chart | Photo |
| Fast | Heatmap | Chart | Photo |
The CAD at the max refresh rate of 60Hz is bad. Fast-moving objects are blurry, which you can notice even while scrolling through long documents quickly. Unfortunately, using the 'Fast' overdrive setting instead of 'Normal' results in inverse ghosting.
This monitor doesn't support a 120Hz signal.
This monitor doesn't support a 120Hz signal.

The CAD at 60Hz is bad. Fast-moving objects are blurry, which you can notice even while scrolling through long documents quickly. Unfortunately, using the 'Fast' overdrive setting instead of 'Normal' results in inverse ghosting.
This monitor doesn't have a backlight strobing feature to reduce persistence blur.
This monitor doesn't support VRR, so there's no VRR flicker.
The backlight remains flicker-free at all brightness levels, which helps reduce eye strain if you're sensitive to flicker.
The monitor has low input lag for a responsive feel.
This monitor can function as a USB hub for up to four devices. It can also provide power to your USB devices while in standby mode.
| Connection | HDMI 2.0 | USB-C to DisplayPort |
| Max Refresh Rate | 60Hz | 60Hz |
| VRR Range | N/A | N/A |
| HDR | No | No |
The monitor works well with macOS. When using a MacBook, windows return to their original position when you open the lid or wake the laptop up from sleep.
This monitor has a limited number of extra features, including:
- ComfortView Plus: Reduces blue light to help minimize eye strain.
- Kensington Lock: You can use this to secure the monitor to a solid object.
