Best Buy Drops 27-Inch QD-OLED Gaming Monitor to $329.99

Best Buy reduced the price of the Acer Predator XB27OU by $50 on October 23, 2026. The 27-inch display now costs $329.99, a price point that lowers the barrier for gamers considering a switch from traditional IPS panels to OLED screens.

The monitor features a 26.5-inch QD-OLED panel with a maximum resolution of 2,560 by 1,440 pixels. This resolution, often referred to as QHD or 2K, is designed to work well with mid-range graphics cards. The display does not place excessive demands on the hardware, allowing for stable frame rates without requiring top-tier components.

Performance metrics emphasize speed. The screen refreshes at 240Hz and achieves a gray-to-gray response time of 0.03 milliseconds. These specifications help eliminate motion blur and ghosting, issues that are more common on slower displays. The monitor also supports AMD FreeSync Premium, which synchronizes the refresh rate with the game's frame output to prevent screen tearing.

Color accuracy is a primary feature of the QD-OLED technology used in this model. The display covers 99% of the DCI-P3 color gamut and maintains a Delta E accuracy below 2. It supports HDR10 and uses 10-bit color depth to enhance contrast and brightness. The OLED panel produces deep blacks and high contrast, making images appear more vivid compared to standard dynamic range screens.

Connectivity options include two HDMI 2.1 ports and one DisplayPort 1.4 port. This setup allows users to connect a gaming PC and multiple game consoles to the same monitor. The price reduction positions the device as an affordable entry point into the latest display technology for home setups.

Shoppers can purchase the Acer Predator XB27OU at Best Buy for $329.99. The offer is currently active as of the publication date.
