10 Best 4 K 240 Hz Monitors 2026 in the United States

The ASUS ROG Swift PG32UCDM is a top-tier choice for gamers seeking a 32-inch 4K monitor. The sharp UHD resolution (3840 x 2160) combined with the QD-OLED panel ensures stunning visuals and vibrant colors, making the gaming experience truly immersive. The standout feature is its 240Hz refresh rate, which provides ultra-smooth motion, perfect for fast-paced games. Additionally, the incredibly fast 0.03ms response time virtually eliminates motion blur, enhancing clarity during intense gaming sessions.

The integration of G-SYNC compatibility helps to reduce screen tearing, ensuring a smoother gaming experience. The monitor's advanced heat management with a custom heatsink and graphene film is designed to mitigate the risk of burn-in, which is often a concern with OLED panels. Furthermore, it covers 99% of the DCI-P3 color gamut and supports true 10-bit color, rendering more detailed and accurate colors. VESA DisplayHDR 400 True Black compliance also enhances the HDR performance, offering deeper blacks and brighter highlights.

However, some potential drawbacks include its substantial size and weight (21 x 38 x 49 inches, 19.4 pounds), which might require a sturdy setup. Also, while the monitor offers extensive connectivity options, including 90W USB-C, it may be relatively more expensive compared to other monitors in the market. Despite these minor drawbacks, the ASUS ROG Swift PG32UCDM stands out as an excellent monitor for gamers looking for high performance and stunning visual quality.

The ASUS ROG Swift PG27AQDM is a 27-inch QHD (2560x1440) gaming monitor that offers a very fast 240Hz refresh rate and an ultra-quick 0.03ms response time, making it excellent for smooth and responsive gaming. Its OLED panel stands out by delivering deep blacks, vibrant colors covering 99% of the DCI-P3 color range, and impressive HDR brightness peaks, which combine to provide a visually stunning experience especially for gamers who value image quality. The matte anti-glare coating helps reduce reflections without sacrificing color accuracy.

It supports G-SYNC compatibility, ensuring tear-free gameplay when paired with NVIDIA graphics cards, which helps maintain smooth visuals during fast action. Connectivity includes DisplayPort and USB 3.0 ports, which are standard for gaming setups. While this monitor is QHD and not 4K, it still hits the high refresh rate mark of 240Hz, which many gamers prioritize over resolution for competitive play.

The OLED panel does raise some concern about potential burn-in over time, but ASUS has implemented heat management and voltage optimization to minimize this risk. If you want a high-refresh, color-rich monitor with extremely fast response times and can accept QHD resolution instead of 4K, this model delivers a premium gaming experience. For those requiring 4K resolution or who are worried about OLED burn-in, exploring other options may be advisable.

The MSI MPG 321CURX QD-OLED is a 32-inch 4K monitor designed for users who want ultra-smooth motion and stunning visuals. It offers a sharp 3840 x 2160 UHD resolution combined with a very fast 240Hz refresh rate, making it great for gaming or fast-paced content where every frame counts. Its QD-OLED panel delivers vibrant colors with excellent contrast and deep blacks, thanks to its VESA DisplayHDR True Black 400 certification. The response time is incredibly quick at just 0.03ms, reducing motion blur for a clear picture during fast action.

Connectivity-wise, it supports HDMI 2.1 with full 48 Gbps bandwidth, allowing 4K at 240Hz, and also includes DisplayPort for versatile connection options. Adaptive Sync technology helps prevent screen tearing, improving the smoothness of gameplay or video playback. On the downside, the glossy screen surface might cause some reflections depending on your lighting, and as an OLED panel, there’s a slight risk of burn-in over long periods of static images, although MSI offers a 3-year burn-in warranty to ease concerns.

This monitor is best suited for gamers and creators looking for top-tier image quality and speed in 4K, but casual users might find it more advanced (and pricier) than needed.
