Acer 27-inch gaming monitor drops to $329.99 at Best Buy

Best Buy is selling a 27-inch Acer Predator gaming monitor for $329.99.

The price tag on the Predator XB27OU fell by $50 on October 23, 2026. This discount targets gamers who want to switch from traditional IPS screens to OLED technology without a large price increase.

The monitor features a 26.5-inch QD-OLED panel. It displays images at a maximum resolution of 2,560 x 1,440 pixels, a standard known as QHD or 2K. This resolution fits well with mid-range gaming PCs, as standard graphics cards can handle the frame rate and pixel count demands.

Performance specs focus on speed. The screen refreshes 240 times per second. It also has a gray-to-gray response time of 0.03 milliseconds. The OLED technology enables this rapid response, which helps prevent the ghosting artifacts common on slower displays.

The monitor supports AMD's FreeSync Premium. This feature synchronizes the display refresh rate with the game's frame rate. The result is the removal of screen tearing. Color quality is also a key feature. The panel covers 99% of the DCI-P3 color gamut. It maintains a Delta E accuracy figure below 2 and supports HDR10.

HDR10 is a 10-bit color standard that boosts contrast and brightness. OLED screens are known for deep blacks and high contrast, which makes images appear more vivid. The unit includes two HDMI 2.1 ports and one DisplayPort 1.4 port. These connections allow users to plug in a gaming PC and multiple consoles simultaneously.

The $329.99 price makes the latest display technology available at a lower cost. Shoppers can purchase the Acer Predator XB27OU at Best Buy stores and online.
