Acer 27-inch QD-OLED gaming monitor costs $329.99 at Best Buy

Gamers upgrading from IPS displays can now purchase a 27-inch QD-OLED monitor for $329.99 at Best Buy. The retailer reduced the price of the Acer Predator XB27OU by $50 as of October 23, 2026. This discount targets consumers seeking a lower-cost entry point into OLED technology without sacrificing high refresh rates or color accuracy.

The display utilizes a 26.5-inch panel with a maximum resolution of 2,560 x 1,440 pixels. Tom's Hardware notes that this QHD specification is well-suited for mid-range gaming systems. Graphics cards in that tier typically handle the frame rate and resolution demands of this monitor without significant strain, making it a practical choice for builders with budget constraints.

Performance metrics prioritize speed. The screen refreshes at 240Hz and maintains a gray-to-gray response time of 0.03ms. These figures result from the OLED technology, which allows for rapid pixel transitions. Tom's Hardware states that this combination produces smooth motion and eliminates the ghosting effects common on slower LCD panels.

The monitor supports AMD FreeSync Premium, which synchronizes the refresh rate to the frame rate output by the game. This alignment prevents screen tearing during gameplay. In terms of color, the panel covers 99% of the DCI-P3 gamut. It also carries a Delta E accuracy rating below 2 and supports HDR10, a 10-bit standard that enhances contrast and brightness relative to standard dynamic range.

Connectivity options include two HDMI 2.1 ports and one DisplayPort 1.4 port. This configuration allows users to connect a personal computer and multiple game consoles to a single screen. The reduced price makes this specific hardware configuration accessible to a wider range of buyers who have previously viewed QD-OLED panels as a premium expense.

Shoppers can currently find the Acer Predator XB27OU at the Best Buy website and in stores for $329.99. The price cut represents a $50 reduction from the previous retail figure. The monitor remains available in this configuration while stock lasts at the retailer.
