10 Best G Sync 240 Hz Monitor 2025 in the United States

The ASUS ROG Swift PG27UCDM is a high-end 27-inch gaming monitor boasting an impressive 4K resolution with a very fast 240Hz refresh rate and an ultra-low 0.03ms response time. It uses the latest QD-OLED panel technology, which means you get incredibly sharp images, vibrant colors with 99% DCI-P3 coverage, and excellent HDR performance thanks to true 10-bit color depth and Dolby Vision support. Being G-SYNC compatible ensures smooth gameplay without screen tearing, which is great for serious gamers seeking fluid visuals. The monitor also includes thoughtful features like ASUS’s OLED Anti-Flicker 2.0 and a proximity sensor that helps reduce eye strain and burn-in risk by turning off the screen when you're away.

Connectivity options are extensive, featuring DisplayPort 2.1a, HDMI 2.1, and USB-C with power delivery, so it works well with modern gaming PCs and peripherals. While the 26.5-inch size is slightly smaller than some might expect for 4K, it offers a sharp and immersive experience without needing to move your eyes much. This is a premium product, likely with a higher price point, and while the OLED panel delivers stunning visuals, OLED can require mindful usage to avoid long-term burn-in despite the built-in protections.

This monitor is ideal for gamers who want top-tier speed and image quality, as well as creative users who value accurate color reproduction.

The ASUS ROG Swift PG27AQDM is a 27-inch gaming monitor that offers a QHD (2560x1440) resolution with an impressive 240Hz refresh rate, which is excellent for smooth and responsive gameplay, especially in fast-paced games. It features an OLED panel, known for delivering deep blacks and vibrant colors, with a very fast 0.03 ms response time that helps reduce motion blur and ghosting. The monitor is G-Sync compatible, meaning it syncs well with NVIDIA graphics cards to provide tear-free and stutter-free gaming experiences.

One of the stand-out features is its high brightness with up to 1000 nits peak (in HDR mode) and 99% DCI-P3 color gamut coverage, making it a great choice for those who care about accurate and vivid visuals, whether gaming or content creation. The anti-glare micro-texture coating helps minimize reflections without affecting color quality, improving visibility in brightly lit rooms. The monitor also comes with smart heat management to reduce the risk of OLED burn-in, which can be a concern with OLED screens during prolonged static image display.

Connectivity includes DisplayPort and USB 3.0 ports, providing modern connection options. The package also offers useful extras like a VESA mount kit and a 3-month Adobe Creative Cloud subscription, which may appeal to creative professionals. While the 27-inch screen size and 1440p resolution hit a sweet spot for many gamers, those preferring larger screens or 4K resolution might find it limiting. OLED monitors tend to carry a higher price compared to traditional LCDs, and despite heat management features, some users may still be cautious about long-term burn-in risks. Additionally, its matte screen surface reduces glare but can slightly soften the picture compared to glossy screens. This monitor suits gamers seeking top-tier speed and color performance with G-Sync support, as well as creators who value color accuracy and HDR, balancing fast gameplay features with rich visuals while considering budget and screen size preferences.

The ASUS ROG Swift 32” 4K OLED Gaming Monitor (PG32UCDM) is designed to deliver an exceptional gaming experience. With a UHD resolution of 3840 x 2160 and a 240Hz refresh rate, it ensures smooth and detailed visuals, making it ideal for high-end gaming. The 0.03ms response time is incredibly fast, reducing motion blur and providing a competitive edge in fast-paced games. G-Sync compatibility further enhances gameplay by minimizing screen tearing and stutter.

The QD-OLED panel offers rich colors and deep blacks, covering 99% of the DCI-P3 gamut and supporting true 10-bit color for vibrant and accurate visuals. The VESA DisplayHDR 400 True Black compliance ensures excellent HDR performance, making it suitable for both gaming and media consumption. Heat management is well-addressed with a custom heatsink and graphene film, reducing the risk of burn-in. Connectivity options are robust, including a 90W USB-C port, which is convenient for connecting multiple devices.

However, the premium features come at a hefty price tag, and its large size (32 inches) might be too big for some setups. Additionally, while it has advanced heat management, OLED burn-in concerns may still linger for some users. Despite these potential drawbacks, the ASUS ROG Swift PG32UCDM stands out as a top-tier choice for gamers seeking high performance and vivid visuals in their monitor.
