4 Best 4 K 240 Hz Gaming Monitors 2025 in the United States

The BenQ ZOWIE XL2540K stands out with its lightning-fast 240Hz refresh rate, which is ideal for competitive gaming, ensuring smooth and fluid motion. The 1ms response time further enhances this, minimizing motion blur and ghosting, essential for fast-paced games. Its Full HD 1080p resolution might be a drawback for those seeking higher clarity and detail typical of 4K monitors, but it is still sufficient for most gaming needs and helps achieve higher frame rates.

Adaptive Sync Technology is likely present to reduce screen tearing, crucial for uninterrupted gameplay. Ergonomics are excellent, with a redesigned base for more desk space and flexible height and tilt adjustments for personalized setups. Additional features like the XL Setting to Share and customizable quick menu add convenience for users. However, accessories like the S-switch remote control and Shield are sold separately, potentially adding to the cost.

While not a 4K monitor, the XL2540K excels in other areas, making it a solid choice for gamers prioritizing high refresh rates and responsive gameplay over resolution.

The KOORUI 27 Inch Gaming Monitor offers a solid performance for gamers, especially those on a budget. With a Full HD resolution of 1920x1080 pixels on a 27-inch screen, it delivers sharp and clear images. The standout feature is its impressive 240Hz refresh rate combined with a 1ms response time, which ensures smooth and responsive gameplay, crucial for fast-paced games. The inclusion of Adaptive Sync technology further enhances the gaming experience by reducing screen tearing and stuttering.

The monitor covers 90% of the DCI-P3 and 100% of the sRGB color gamut, providing vibrant and accurate colors, which is a plus for both gaming and content creation. However, the brightness level is 300 nits, which might not be ideal for brightly lit environments. The monitor is designed with ergonomics in mind, allowing tilt adjustments from -5 to 20 degrees and VESA compatibility for wall mounting, though it lacks height adjustment or swivel options.

Connectivity is straightforward with HDMI and DisplayPort options, catering to various devices like PCs and gaming consoles. Additionally, a 3.5mm headphone jack offers flexibility for audio output. While the design is modern and sleek, the stand's adjustability is somewhat limited, and users looking for pivot or height adjustment may need to look elsewhere. The monitor comes with a reliable service support, including a 1-year warranty on the display and 3 years on other accessories, ensuring peace of mind. In summary, the KOORUI 27 Inch Gaming Monitor is a strong contender in the 240Hz gaming monitor category, offering excellent performance and color accuracy at a competitive price, though its limited ergonomics and brightness might be a consideration for some users.

The BenQ MOBIUZ EX270M Gaming Monitor is a solid choice for gamers seeking smooth and immersive gameplay. Its standout feature is the 240Hz refresh rate combined with a fast 1ms response time, ensuring highly fluid action with minimal motion blur—ideal for fast-paced games. The Full HD resolution (1080p) on a 27-inch IPS panel provides clear and vibrant visuals with wide viewing angles. However, for those looking for 4K resolution, this monitor might fall short with its FHD display.

BenQ's HDRi technology and additional image optimization features like Light Tuner and Black eQualizer enhance the visual experience by providing better contrast and detail in different lighting conditions. The inclusion of AMD FreeSync Premium helps reduce screen tearing and stuttering, contributing to smoother gameplay. One notable extra is the built-in 2.1 speakers with a 5W subwoofer, offering enhanced audio quality, which is a nice bonus for those who appreciate good sound without external speakers.

The monitor is designed with ergonomics in mind, featuring adjustable height, swivel, and tilt for a comfortable setup. It also includes Eye-Care technology, making it easier on the eyes during long gaming sessions. Connectivity options are comprehensive, with HDMI, DisplayPort, and USB hub compatibility, ensuring ease of connection to gaming consoles and PCs. Despite its many strengths, the glossy screen surface might be prone to reflections, and the monitor's weight (20.3 pounds) may require a sturdy desk setup. In summary, the BenQ MOBIUZ EX270M excels in delivering high refresh rates and rapid response times, making it a great option for competitive gamers, though its FHD resolution may not satisfy those seeking 4K visuals.
