Best Value: ASUS VA24EHE, reliable 24-inch 1080p performance for everyday computing and office work.

1. ASUS VP28UQGL

This 28-inch 4K monitor stands out as the premium choice for anyone working with high-resolution content without exceeding the £400 ceiling. The VP28UQGL delivers exceptional pixel density that makes text crisp and images remarkably sharp, particularly useful for video editing, photo work and anyone who wants to see fine detail on screen. The 3840 x 2160 resolution provides four times the pixels of standard 1080p displays, creating an immersive viewing experience that justifies the investment for demanding workflows.

The TN panel technology ensures rapid 1 ms response times, which benefits gamers and those who value snappy cursor movement, though viewing angles are more limited than IPS alternatives. Colour accuracy is respectable from ASUS's factory calibration, and the 60 Hz refresh rate handles most professional tasks smoothly.

The VP28UQGL remains competitive against far pricier alternatives, delivering measurable advantages for content-heavy work. Its price point makes it exceptional value in the 4K segment, though power consumption runs higher than smaller models.

2. ASUS VA24EHE

The VA24EHE represents straightforward, affordable reliability for everyday computing. This 24-inch Full HD display prioritises simplicity and value, offering solid performance for office work, browsing, document editing and general-purpose tasks without unnecessary features or complexity. The 1920 x 1080 resolution remains the standard for this size class, providing adequate clarity for most work without demanding expensive hardware to drive it.

The VA panel delivers superior contrast compared to IPS, producing deeper blacks and punchier visuals, which many users prefer for everyday content consumption. Response time sits at 5 ms, perfectly acceptable for non-gaming use, and the 60 Hz refresh rate covers all standard office scenarios. The monitor includes traditional D-Sub and DVI connectivity, making it compatible with older systems and corporate environments that may lack modern digital ports. Build quality is robust but utilitarian, with a tilt-only stand offering basic adjustability. At just 3.3 kg, it's lightweight for easy repositioning or transport between desks.

This monitor excels for budget-conscious buyers, office environments where multiple screens are needed, and anyone seeking dependable performance without paying for gaming features or professional colour accuracy. It's equally suited to home office setups, student accommodation and light productivity work. The VA24EHE proves that essential monitor functionality doesn't require premium pricing or advanced specifications.

3. ASUS VG249Q1A

The VG249Q1A balances gaming performance with everyday usability in a 24-inch package, making it ideal for users who divide time between work and recreational gaming. The IPS panel provides wider viewing angles than TN or VA alternatives, maintaining colour accuracy even when viewed from the side, valuable for presentations or collaborative work. The 75 Hz refresh rate represents a meaningful upgrade over standard 60 Hz, delivering noticeably smoother motion without requiring high-end graphics hardware.

The 1 ms response time ensures virtually no ghosting during fast scrolling or gaming sequences, and the Full HD resolution maximises the usefulness of that 75 Hz capability without excessive bandwidth demands. The monitor includes AMD FreeSync support, synchronising frame rates with compatible graphics cards to eliminate tearing during gaming. Colour reproduction is accurate from the factory, suitable for light content creation and general colour-sensitive work. HDMI and DisplayPort connectivity provide modern connectivity options, and the stand offers height, tilt and pivot adjustments for customised positioning. The efficient LED backlight keeps power consumption reasonable despite the performance-oriented design.

This monitor suits students and professionals who game after work, streamers and content creators requiring colour accuracy alongside responsive performance, and anyone wanting more than basic office functionality. The VG249Q1A delivers competitive gaming benefits without specialist-only features or extreme pricing.

4. ASUS PA247CV

The PA247CV targets photographers, graphic designers and anyone needing accurate colour reproduction within a tight budget. ASUS positions this as a professional-grade display despite the affordable price, incorporating factory calibration, colour gamut certification and hardware specifically designed for content creation workflows. The 24-inch IPS panel provides the wide viewing angles essential when multiple people need to review images, and the colour accuracy makes subtle tonal adjustments visible on screen.

The monitor covers 99 per cent of the sRGB colour space, matching standards used in professional photography and web design, ensuring colours appear correctly across different viewing platforms. The 1920 x 1080 resolution provides sufficient pixel density for detailed work without overwhelming smaller screens. USB-C connectivity with Power Delivery functionality adds modern convenience, allowing the monitor to charge compatible devices whilst displaying content. HDMI and DisplayPort options ensure compatibility with varied professional equipment. The 5 ms response time is standard for colour-accurate work, where speed takes secondary importance to fidelity. The stand includes height adjustment and pivot rotation, enabling portrait orientation for document review or vertical image composition work.

This monitor suits photographers wanting to buy once and buy right, freelance designers managing client colour requirements, and anyone taking visual output seriously. The PA247CV delivers genuine professional features without specialist-only pricing, making it exceptional value for creative professionals.

How We Picked

Our selection process prioritised monitors delivering genuine value within the under-£400 constraint. We evaluated technical specifications including resolution, panel technology, refresh rate and response time against real-world usage patterns. Colour accuracy and viewing angles determined suitability for professional work versus gaming or general office use. We assessed connectivity options, stand adjustability and weight to understand practical usability beyond raw performance numbers. Build quality and warranty coverage factored into long-term value assessment. We cross-referenced user feedback from verified purchases, examining common issues and satisfaction patterns to identify models with reliable track records. This approach ensured our recommendations reflect not just specifications, but actual performance and user experience across diverse use cases. Price fluctuations required verification immediately before publication to confirm models remained within the stated budget.

Buying Guide

Choosing a monitor under £400 requires balancing resolution, panel type, size and features against your primary use case. Resolution fundamentally determines clarity and productivity: 1920 x 1080 Full HD suits everyday work and entertainment at 24 inches, whilst 1920 x 1200 WUXGA at 27 inches adds vertical space for spreadsheets and multitasking without excessive cost. 4K displays starting at 27-28 inches offer exceptional sharpness for professional content creation but demand more graphics processing power and come at the upper price limit.

Panel technology significantly affects your experience: VA panels deliver superior contrast and blacks, suiting general users who prefer punchy visuals. IPS panels offer wider viewing angles and colour accuracy essential for creative professionals and collaborative environments. TN panels provide the fastest response times but limited angles, historically preferred by gamers though less relevant at lower refresh rates under £400. For most users, IPS or VA represent better value than TN in this price range.

Screen size involves compromise between visibility and desk space: 21.5-24 inches suit compact desks and portable setups, whilst 27-28 inches provide noticeable productivity benefits for document work and multitasking at the cost of desktop footprint. Larger displays create eye strain if positioned too close or at improper angles. Consider your typical viewing distance and the monitor's intended role before committing to size.

Refresh rate and response time matter primarily for gaming: 60 Hz standard refresh is fine for work and video playback, whilst 75+ Hz improves smoothness noticeably during scrolling and gaming. Response time below 5 ms reduces ghosting during fast motion, with 1 ms becoming valuable only for competitive gaming. Non-gamers rarely notice response time differences beyond 5 ms.

Connectivity deserves attention for long-term compatibility: modern monitors need HDMI or DisplayPort, though legacy D-Sub and DVI still exist in older systems. USB-C with Power Delivery adds convenience for professional users. Stand adjustability determines ergonomic positioning: height adjustment proves essential for avoiding neck strain during extended use, whilst pivot and tilt offer additional flexibility for specific workflows.

Final Verdict

The ASUS VP28UQGL emerges as the overall winner, delivering exceptional 4K clarity and professional colour calibration that command respect against far pricier competitors. The extraordinary resolution density and vibrant TN panel response create a monitor suitable for creative professionals, content creators and anyone demanding precise visual representation. Its position at the upper boundary of the £400 budget feels justified by the quantum leap in pixel clarity compared to 1080p alternatives.

However, the ASUS VA24EHE deserves equal consideration as best value, proving that essential monitor functionality doesn't require premium pricing or advanced specifications. For general office work, browsing and everyday computing, it delivers reliable performance that exceeds expectations at its modest price point. The straightforward feature set and proven reliability make it ideal for cost-conscious buyers or office environments deploying multiple screens.

The remaining models address specific requirements excellently: the VG249Q1A suits gaming-focused users, the PA247CV targets photographers and designers, the VP229HE serves ultrabudget needs, and the VA27DQSB benefits productivity-focused professionals. None represent poor choices, rather each excels within its intended context. Your decision should prioritise your primary monitor use case, desktop constraints and budget allocation. ASUS's budget range demonstrates that affordable monitors no longer mean compromising on fundamental quality or features, offering genuine value across diverse user requirements and preferences.
