Buying Reasons
It’s hard to look away
Easy on the eyes: ComfortView Plus is an always-on, built-in low blue light screen that optimizes eye comfort by reducing potentially harmful blue light emissions while delivering excellent color accuracy.
Color consistency comes standard: See consistent, vibrant colors across a wide viewing angle enabled by In-Plane Switching (IPS) technology. With 99% sRGB coverage to an accuracy of Delta-E less than 2, you get precise hues right out of the box.
See more, scroll less: Boost productivity with an extended vertical view on this 24" 16:10 WUXGA (1920 x 1200) display which provides 11% more on-screen real estate.
Your productivity hub
Connect to productivity: With connectivity options like RJ45 and USB-C®, your monitor delivers robust Ethernet and power (up to 90W)—all in a clutter-free setup.
Quick access: Conveniently placed SuperSpeed USB 5Gbps and USB-C ports located at the front of the monitor allow quick connections to storage devices, mobile phones and other peripherals while enabling up to 15W of power delivery (via USB-C).
Enhanced manageability: Managing your monitor is easy with MAC Address pass-through, PXE Boot, and Wake-on-LAN conveniently built in.
Set up for more: DP out connectivity enables a multi-monitor setup by daisy chaining up to three monitors.
A step forward in design
Beauty meets function: Masterfully crafted with a premium platinum silver finish, small base and an elegant cable management system that hides cords within the monitor riser.
Easy to use: Navigate the menu and adjust screen settings with the joystick control. We’ve also given you the option to snap on the Dell Slim Soundbar (SB521A) and enjoy exceptional sound quality.
Comfort is key: Tilt, swivel, pivot and adjust the height of your monitor to a maximum of 150mm because you should be comfortable while you work.
Expand your efficiency: Experience a seamless view across multiple monitors with the virtually borderless InfinityEdge design. And, with a dual monitor setup, you can increase your productivity by up to 21%.
Green thinking: For today and tomorrow
Environmental standards: This monitor meets the latest regulatory and environmental standards such as EnergyStar®, EPEAT® Gold, and TCO certified.
Eco-conscious packaging: To reduce our manufacturing impact on the environment, this monitor is shipped Styrofoam-free and the packaging is made of at least 75% recycled cardboard.
Energy conservation: Save energy when your monitor is not in use with PowerNap, a feature that dims or puts your monitor to sleep when it’s not in use.
Dell Display Manager
Productive at every level: Easy Arrange allows you to easily tile multiple applications across one or more screens with 38 pre-set window partitions and the ability to personalize up to five windows, giving you improved multitasking abilities.
Seamless transitions: The auto-restore feature remembers where you left off, so applications will go back to where you left them, even after you’ve unplugged.
More ways to manage: Asset management reports allow IT managers to quickly capture and track monitor information as well as configure multiple monitors at once through a single setup.
The key to convenience: Shortcut keys can save you even more time, letting you easily configure your display management settings so you can get to work faster.
A brand you can rely on
As the No. 1 monitor brand worldwide for seven consecutive years (2013 to 2020), we take pride in our unyielding commitment to quality and the utmost satisfaction of our customers.
Premium Panel Exchange
The Dell Premium Panel Exchange allows a free panel replacement during the Limited Hardware Warranty period even if only one bright pixel is found.

Product Carbon Footprint (PCF):
1. Dell generally uses the PAIA (Product Attribute to Impact Algorithm) tool for product carbon footprint calculations. http://msl.mit.edu/projects/paia/main.html
2. Docking station related PCFs are extracted from corresponding LCAs and as such do not follow the PAIA methodology used for calculating other PCFs in this report
3. PAIA method is developed by the Massachusetts Institute of Technology’s Materials Systems Laboratory and partners.
4. All estimates of carbon footprint are uncertain. Dell Technologies reports the 5th and 95th percentile of the carbon footprint estimate to reflect this uncertainty wherever possible. (https://www.dell.com/en-us/dt/corporate/social-impact/advancing-sustainability/climate-action/product-carbon-footprints.htm#tab0=0)
5. Please note the emission estimate in this report is calculated using the mean value along with the standard deviation for that product model.
6. Use of default inputs (i.e. not primary data) and assumptions on location of use and other fields can introduce a standard deviation which must be taken into account while completing the calculations.
7. Please note, PAIA uses the Ecoinvent Database (https://ecoinvent.org/the-ecoinvent-database/) whenever primary data is not made available for calculations.
8. For client and commercial end user computing products, minimum configurations were assumed for calculations. For Server and Storage products, typical configurations or ENERGY STAR (https://www.energystar.gov/products) configurations were used for calculations.
9. Use Phase emissions were calculated based on the location of use as "Europe" i.e. the Use Phase emissions are not specific to a single country / location.
10. The report does provide an option for a total emissions number for manufacturing, transport and end of life while leaving the use phase emissions out, in case the customer uses their own calculation methodology for use phase emissions.
11. Typical lifetime usage assumptions are either four or five years based on the product line.
12. For detailed assumptions please refer to the product datasheets in the Dell Technologies reports (https://www.dell.com/en-us/dt/corporate/social-impact/advancing-sustainability/climate-action/product-carbon-footprints.htm#tab0=0).
13. The results from the PAIA tool are liable to change over time as the methodology is improved and datasets are updated. The PAIA version used to calculate emissions has been indicated with each record in the report when available.
14. Metrics used: The units for global warming potential are in kgCO2-equivalent or MT (metric ton) CO2-equivalent (CO2e).
