The Asus ROG Strix OLED XG27ACDNG is down to $599 on Amazon, a $160 discount from its usual $759 price. This is a high-end gaming monitor designed for players who want top-tier performance without stepping up to a larger display. It pairs a 27-inch QD-OLED panel with a 2560x1440 resolution and a 360Hz refresh rate, a combination that has become one of the most sought-after setups for competitive gaming, and so placing the XG27ACDNG in direct competition with premium models like the Alienware AW2725DF.

Image quality is one of the monitor's biggest strengths. The QD-OLED panel delivers deep blacks and excellent contrast, making games and movies look especially striking in darker rooms. The monitor also supports both FreeSync and G-Sync compatibility, helping gameplay stay smooth across a wide range of frame rates on either AMD or Nvidia systems. Performance is equally impressive, especially in motion handling—the 360Hz refresh rate and 0.03ms response time help fast-moving objects stay sharp, making competitive shooters, racing games, and esports titles feel particularly responsive. Input lag is also very low, which further contributes to that sense of immediacy.

Outside of gaming, Asus has also included several features aimed at long-term usability—including a built-in heatsink and OLED Care+ tools, which are designed to help minimize the risk of burn-in, a USB-C port with 90W power delivery, a USB hub, and a KVM switch—making the monitor more useful for work setups and multi-device users. That said, like many QD-OLED monitors, the panel can lose some of its inky-black appearance in bright rooms, where ambient light may cause darker areas of the screen to take on a slight purple tint. VRR flicker can also become noticeable when frame rates fluctuate, particularly in darker scenes, and there are no built-in speakers. Even so, for anyone looking for a 1440p OLED gaming monitor with an exceptionally high refresh rate, this discount makes one of ASUS's strongest gaming displays considerably easier to justify.
