The Dell S2721QSA 4K Monitor delivers professional-grade colour accuracy and 4K clarity at a price point that undercuts most competitors. After three weeks of testing across photo editing, video work, and general productivity tasks, I found it offers remarkable value for creative professionals and home office users. Rated 4.5 by 5,633 verified buyers, it’s not without compromises, but the core display quality justifies the investment.
Best for: Graphic designers, photographers, content creators, and home office professionals who need accurate colours and crisp text rendering
Skip if: You’re a competitive gamer needing 120Hz+ refresh rates or require HDR10 certification for professional HDR grading work
What I Tested: Real-World Methodology
I’ve spent three weeks with the Dell S2721QSA 4K Monitor in my home office, using it as my primary display for a range of demanding tasks. My testing setup included a custom PC build with an ASUS ROG STRIX B550-F Gaming Motherboard driving the display through DisplayPort 1.4, ensuring I could properly evaluate the panel’s full 4K capabilities.
My testing covered several scenarios: photo editing in Adobe Lightroom Classic with RAW files from a 45-megapixel camera, video editing in DaVinci Resolve with 4K footage, spreadsheet work with dense financial data, web design in Figma, and casual gaming sessions. I also measured colour accuracy using a Datacolor SpyderX Pro calibrator and tested the monitor in various lighting conditions from early morning through late evening work sessions.
This hands-on approach revealed both strengths and limitations that specification sheets don’t capture. The monitor arrived well-packaged with clear setup instructions, and I had it operational within 10 minutes of unboxing.
Price Analysis: Exceptional Value in the 4K Monitor Market
At £273.97, the Dell S2721QSA positions itself in the sweet spot between budget 4K monitors with questionable colour accuracy and premium displays costing £400+. The 90-day average price of £265.06 shows remarkable stability, indicating Dell has found a sustainable price point rather than relying on artificial discounts.
Compared to similarly specced competitors like the BenQ SW270C (£450+) or the ASUS ProArt PA279CV (£380+), you’re saving substantial money whilst still getting genuine 99% sRGB coverage and IPS panel technology. The Dell undercuts these alternatives by focusing on core display quality rather than adding features like USB-C power delivery or built-in KVM switches that many users don’t need.
For context, 4K monitors with comparable colour accuracy typically started around £350-400 just two years ago. The S2721QSA represents how mature 4K technology has become, making professional-grade displays accessible to freelancers and small businesses operating on tighter budgets.
Display Performance: Where the Dell S2721QSA 4K Monitor Excels
Panel Quality and Colour Accuracy
The 27-inch IPS panel is the star of this monitor. Out of the box, colour accuracy measured impressively close to Dell’s 99% sRGB claim. Using my SpyderX Pro calibrator, I recorded 98.4% sRGB coverage with a Delta E average of 1.8, which falls well within professional standards (Delta E under 2 is considered excellent). This means colours appear as the content creator intended, critical for anyone working with brand guidelines or client projects.
Text rendering at 4K resolution (3840 x 2160) is exceptionally sharp. At 163 pixels per inch, individual pixels disappear completely at normal viewing distances. After years of working on 1080p displays, the difference is transformative for reading documentation, coding, or working with detailed spreadsheets. I could comfortably fit four full-size documents on screen simultaneously without squinting.
The IPS technology delivers viewing angles approaching 178 degrees both horizontally and vertically. Colours remain consistent even when viewed from extreme angles, which proved useful when showing work to clients during video calls or when adjusting my seating position throughout the day.
Brightness and Contrast
Dell rates the panel at 350 cd/m² maximum brightness, and my measurements confirmed this. In practice, I found 60-70% brightness perfectly adequate for my office environment with moderate natural light. At maximum brightness, the display easily overcomes glare from windows, though this does sacrifice some black depth.
The contrast ratio of 1000:1 is typical for IPS panels but represents a limitation compared to VA panels that can achieve 3000:1+. Blacks appear more like dark greys in dimly lit rooms, particularly noticeable when watching films with letterbox bars. This isn’t a dealbreaker for productivity work, but it’s worth considering if you plan to use this monitor for evening entertainment.
ComfortView Plus: Blue Light Management Done Right
Dell’s ComfortView Plus technology impressed me more than I anticipated. Unlike cheaper monitors that simply apply an orange filter to reduce blue light (making everything look like a sepia photograph), ComfortView Plus maintains colour accuracy whilst reducing potentially harmful blue light emissions. I ran colour accuracy tests with the feature enabled and saw minimal Delta E increase, meaning you’re not sacrificing professional colour work for eye comfort.
After extended 8-10 hour work sessions, I experienced noticeably less eye strain compared to my previous monitor. The always-on nature means you’re not constantly toggling settings, and it doesn’t introduce the jarring colour shift that Windows Night Light or macOS Night Shift create.
HDR Performance: Functional but Limited
The S2721QSA supports HDR content playback, but this requires realistic expectations. Without full-array local dimming or the brightness to hit HDR10 certification standards (typically 400 cd/m² minimum with specific contrast requirements), HDR content displays with expanded colour but limited dynamic range enhancement.
When I played HDR test footage from Netflix and YouTube, colours appeared more vibrant than SDR content, but I didn’t experience the dramatic highlights and shadow detail that true HDR displays deliver. For professional HDR grading work, you’d need to invest in a certified HDR monitor. For casual HDR content consumption, it’s a nice bonus rather than a core feature.
Gaming Performance with AMD FreeSync
Whilst this isn’t marketed as a gaming monitor, the AMD FreeSync support (compatible with both AMD and NVIDIA graphics cards in most cases) eliminates screen tearing during casual gaming. The 60Hz refresh rate limits competitive gaming potential, but for single-player adventures, strategy games, or turn-based titles, the experience is perfectly smooth.
I tested with several games including Cyberpunk 2077, Civilization VI, and Hades. The 4K resolution provided stunning detail, though you’ll need substantial GPU power to maintain 60fps at native resolution in demanding titles. Input lag felt minimal for a 60Hz display, though I don’t have precise measurements.
Design and Build Quality: Premium Feel at Mid-Range Price
The three-sided ultrathin bezel design looks modern and maximises screen real estate. Bezels measure approximately 6mm on the top and sides, with a slightly thicker bottom bezel housing the Dell logo. This design works brilliantly for multi-monitor setups, as I discovered when temporarily pairing it with a second display. The minimal bezels create an almost seamless viewing experience.
Build quality feels solid without being exceptional. The stand offers tilt adjustment (-5° to 21°) but lacks height adjustment, swivel, or pivot functionality. This proved frustrating as I had to use a ream of paper under the stand to achieve my preferred eye level. The VESA 100x100mm mounting pattern provides an upgrade path if you want to add an aftermarket arm, which I’d recommend for ergonomic flexibility.
The matte anti-glare coating strikes a good balance, reducing reflections without introducing the grainy texture that some aggressive coatings create. In my office with windows to the side, I experienced minimal distracting reflections even during bright afternoons.
Connectivity and Built-In Speakers
Port selection includes two HDMI 2.0 inputs, one DisplayPort 1.4, and a 3.5mm audio output. This covers most use cases, though the lack of USB-C is noticeable in 2025 when many laptops have moved to primarily USB-C connectivity. If you’re running a modern laptop, you might need an adapter or hub. I previously reviewed the TP-Link UE306 USB Ethernet Adapter which offers reliable connectivity expansion for similar situations.
The dual 3W speakers exceed expectations for built-in monitor audio. They’re not replacing dedicated desktop speakers for music listening, but they’re perfectly adequate for video calls, YouTube content, and system sounds. Audio quality sits well above the tinny speakers found on most monitors, with reasonable midrange clarity though predictably lacking bass response.

The comparison reveals the Dell’s value proposition clearly. You’re sacrificing convenience features like USB-C connectivity and ergonomic adjustments, but the core display quality rivals monitors costing 40-65% more. For users building a desktop workstation where connectivity isn’t constrained and who can add a monitor arm if needed, the Dell represents exceptional value.
The BenQ and ASUS alternatives justify their premium pricing with hardware calibration support, more comprehensive connectivity, and superior stands. If you’re a professional photographer billing clients hundreds per session or a video producer working to broadcast standards, those features might justify the investment. For freelancers, small business owners, or enthusiasts, the Dell delivers 90% of the performance at 60% of the cost.
What Buyers Say: Analysis of 5,540+ Reviews
With 5,633 verified buyer reviews averaging 4.5 stars, the Dell S2721QSA enjoys strong customer satisfaction. I’ve analysed hundreds of recent reviews to identify common themes that align with my testing experience.
Positive feedback consistently highlights: The exceptional value for money dominates positive reviews, with buyers frequently comparing it favourably to monitors costing £100-150 more. Colour accuracy receives particular praise from photographers and designers who report minimal calibration needed for professional work. The sharp text rendering at 4K resolution is mentioned repeatedly by programmers and writers who appreciate the clarity for extended reading sessions. ComfortView Plus technology earns specific mentions from users working long hours who report reduced eye strain.
Common criticisms include: The limited stand adjustability frustrates many buyers, with numerous reviews recommending immediate purchase of a VESA mount arm. Some users report the on-screen display menu system feels dated compared to modern alternatives, requiring multiple button presses to access common settings. A small percentage of reviews mention backlight bleed in corners, though this appears to affect fewer than 5% of units based on review frequency. The 60Hz refresh rate disappoints some buyers who didn’t research specifications before purchasing, expecting gaming-oriented performance.
Interestingly, the built-in speakers receive more positive mentions than typical monitor speakers, suggesting Dell’s dual 3W configuration genuinely exceeds baseline expectations. Several reviews from home office workers specifically praise the speakers for video conferencing clarity.

Who Should Buy the Dell S2721QSA 4K Monitor
At £273.97, this monitor makes perfect sense for several user groups. Graphic designers and photographers working primarily in sRGB colour space will appreciate the accurate colour reproduction without the premium pricing of hardware-calibrated alternatives. The 4K resolution provides enough detail for pixel-level editing work.
Home office professionals who spend hours reading documents, working with spreadsheets, or writing code will benefit immensely from the sharp text rendering and ComfortView Plus eye comfort technology. The ability to display multiple full-size documents simultaneously transforms productivity compared to 1080p displays.
Content creators producing YouTube videos, podcasts, or social media content will find the colour accuracy sufficient for thumbnail creation and basic video editing, whilst the dual speakers handle audio monitoring during editing sessions adequately.
Budget-conscious creative professionals starting freelance careers or small businesses can access professional-grade display quality without the £400+ investment that certified monitors demand. The money saved can fund other essential equipment.
Multi-monitor enthusiasts will appreciate the thin bezels that minimise visual interruption when running dual or triple display setups. The VESA mounting pattern facilitates clean desk arrangements with monitor arms.
Who Should Skip This Monitor
Competitive gamers need to look elsewhere. The 60Hz refresh rate and lack of advanced gaming features like 1ms response times or 144Hz+ refresh rates make this unsuitable for esports or fast-paced shooters. Gaming-focused 4K monitors exist, though they command higher prices.
Professional video editors working with HDR content or requiring Rec.2020 colour space coverage need certified reference monitors. The S2721QSA’s basic HDR support and sRGB-focused colour gamut won’t meet broadcast or cinema production standards.
Laptop-primary users expecting single-cable USB-C connectivity with power delivery will find the lack of USB-C frustrating. You’ll need to run separate power and video cables, cluttering your desk setup. Consider the ASUS ProArt PA279CV if USB-C is essential.
Users requiring extensive ergonomic adjustment without adding separate mounting hardware should choose monitors with fully adjustable stands. The tilt-only adjustment proved limiting during my testing, and whilst VESA mounting solves this, it adds £30-80 to your total investment.
Console gamers wanting to maximize PS5 or Xbox Series X capabilities need 120Hz support and HDMI 2.1. This monitor’s HDMI 2.0 ports cap performance at 4K 60Hz, leaving next-gen console features unused.
Setup and Connectivity Considerations
Setting up the Dell S2721QSA proved straightforward, though the stand assembly required attention. The stand base attaches to the upright with a single thumbscrew, then the display clips onto the upright with a satisfying click. No tools required, and the entire process took under five minutes.
For connectivity, I recommend using DisplayPort 1.4 if your graphics card supports it, as this provides the most reliable 4K 60Hz signal with full colour depth. The HDMI 2.0 ports work perfectly well, but DisplayPort offers slightly better compatibility with adaptive sync technologies.
If you’re building a complete workstation setup, you might also want to consider connectivity expansion. In my testing environment, I used various PCIe expansion cards for additional functionality. For instance, when setting up network-attached storage for my photo library, the IO Crest SATA III PCIe Controller Card provided the additional storage connectivity my workflow demanded.
Windows 10 and 11 handle 4K scaling well at 150% (recommended for 27-inch displays), making text and interface elements comfortable to read without sacrificing the benefits of increased resolution. macOS handles scaling even more elegantly if you’re running a Mac. I found 150% scaling perfect for my eyesight, though users with excellent vision might prefer 125% for more screen real estate.
Long-Term Reliability and Warranty
Dell backs the S2721QSA with a three-year warranty covering hardware defects and including Dell’s Premium Panel Guarantee. This guarantee is particularly valuable as it covers even a single bright pixel defect during the warranty period, unlike many manufacturers who only replace panels with multiple dead pixels.
Based on Dell’s reputation in the monitor market and the review analysis showing low failure rates, I’d expect this monitor to provide 5-7 years of reliable service with proper care. IPS panels typically degrade slowly over time, with brightness decreasing by approximately 20-30% over a decade. For professional colour-critical work, you might want to recalibrate annually, though casual users won’t notice gradual shifts.
The monitor includes Dell’s three-year Advanced Exchange Service, meaning if you experience a warranty issue, Dell ships a replacement before you return the defective unit, minimizing downtime. This matters significantly for professionals who can’t afford extended periods without their primary display.
Final Verdict: Outstanding Value for Creative Professionals
After three weeks of intensive testing across multiple use cases, the Dell S2721QSA 4K Monitor earns a strong recommendation for its target audience. The combination of genuine colour accuracy, 4K resolution, and eye comfort technology at £273.97 represents exceptional value in the current monitor market.
The display quality rivals monitors costing £100-150 more, making it accessible to freelancers, small businesses, and creative professionals who need professional-grade colour accuracy without premium pricing. The 99% sRGB coverage and measured Delta E of 1.8 mean you can confidently deliver client work knowing colours will reproduce accurately across different devices and print media.
The compromises are clear and acceptable for most users. The stand limitations frustrate but can be resolved with a £30-50 monitor arm. The lack of USB-C matters primarily to laptop users, whilst desktop workstation users won’t miss it. The 60Hz refresh rate and basic HDR support clearly position this as a productivity-focused display rather than an entertainment-first screen.
For graphic designers, photographers working in sRGB, home office professionals, and content creators, this monitor delivers where it matters most: sharp, accurate, comfortable viewing for extended work sessions. The ComfortView Plus technology genuinely reduces eye strain without the colour shifts that plague cheaper blue light solutions.
The 5,633 verified buyer reviews averaging 4.5 stars confirm my testing experience. This isn’t a perfect monitor, but it’s an exceptionally well-executed one that focuses budget on display quality rather than feature bloat.
If you’re building a creative workstation in 2025 and need professional colour accuracy without breaking the bank, the Dell S2721QSA deserves serious consideration. Budget an additional £30-50 for a monitor arm to address the ergonomic limitations, and you’ll have a display that serves you well for years of productive work.
