10 Best 4K Gaming Monitors 2025 in the UK

The ASUS ROG Swift OLED PG32UCDM is a top-tier 4K gaming monitor designed to deliver an exceptional gaming experience. Its 32-inch QD-OLED panel provides stunning 4K (3840 x 2160) resolution, ensuring crystal-clear visuals. The monitor's standout feature is its impressive 240 Hz refresh rate paired with an incredibly fast 0.03 ms response time, which means smoother gameplay and reduced motion blur—ideal for competitive gamers looking for precision and speed.

Additionally, the QD-OLED technology offers deep blacks and vibrant colors, further enhanced by its 99% DCI-P3 color gamut and true 10-bit color depth, making it perfect for gamers who also value visual quality in their content consumption or creation. HDR performance is solid with VESA DisplayHDR 400 True Black compliance, providing greater contrast and dynamic range in supported games and media. Adaptive Sync Technology, specifically G-SYNC compatibility, helps eliminate screen tearing, providing a seamless gaming experience.

The monitor includes extensive connectivity options such as DisplayPort 1.4, HDMI 2.1, and USB-C with 90 W power delivery, catering to diverse setup needs. One potential drawback is the glossy screen surface, which might cause reflections in brightly lit environments. Additionally, while the custom heatsink and graphene film offer better heat management to reduce burn-in risk, OLED panels generally have a higher susceptibility to burn-in compared to other panel types. At 8.8 kg, it's slightly hefty, and users should ensure they have a sturdy setup for mounting or placement. Given its feature set, this monitor is highly suited for avid gamers and content creators who need a blend of high performance and exceptional visual quality.

The AOC Gaming U27G3X is a solid choice for gamers looking for a 27-inch 4K monitor. It offers a sharp 3840x2160 resolution with an IPS panel, which means vibrant colors and wide viewing angles. Its standout features include a very fast 1ms response time and a high 160Hz refresh rate, allowing fast-moving games to look smooth without blurring or ghosting.

The monitor supports Adaptive Sync and NVIDIA G-SYNC technology, reducing screen tearing and stuttering for a fluid gaming experience. Connectivity is versatile, with two HDMI 2.1 ports and one DisplayPort 1.4, so it can easily connect to modern gaming consoles and PCs. The screen has a matte finish to reduce glare and includes height adjustment for ergonomic comfort.

This monitor balances speed, image quality, and connectivity well, making it a strong option for gamers who want a responsive 4K display without breaking the bank.

The Dell S2722QC is a 27-inch 4K UHD monitor designed to deliver impressive clarity and vibrant colors, making it suitable for gaming enthusiasts who value visual quality. With its 3840x2160 resolution, users will enjoy detailed images that enhance their gaming experience. The IPS panel ensures good color accuracy and wide viewing angles, which is beneficial for gamers who don't always sit directly in front of the screen.

While the monitor supports AMD FreeSync technology to minimize screen tearing, its 60Hz refresh rate may not meet the needs of gamers seeking ultra-smooth motion in fast-paced games. A higher refresh rate is typically preferred for competitive gaming, where fluidity and responsiveness are crucial. However, the 4ms response time is decent for reducing motion blur. The inclusion of HDR enhances the contrast and color range, offering richer visual detail, especially in HDR-supported games. Connectivity is a standout feature, with USB-C offering simplified connections and power delivery, plus HDMI and USB ports for versatile options.

Cosmetically, its Platinum Silver finish and textured back provide an elegant aesthetic that complements any setup. Built-in speakers offer convenience but may not deliver the depth and quality of dedicated external speakers. For leisurely gaming where graphic quality is prioritized over speed, this monitor is a good choice. Advanced Exchange Service is a reassuring feature, suggesting reliable customer support. Nonetheless, those requiring higher refresh rates for competitive gaming might need to explore other options. The Dell S2722QC balances aesthetic appeal and functional versatility, making it a solid option for casual gamers and multimedia users.
