The Acer Predator X27U A1, a 27-inch QD-OLED gaming monitor aimed squarely at high-refresh-rate enthusiasts, is currently available for $379.99 at Costco, at a $170 discount from its $549.99 list price. The manufacturer’s savings is valid from January 26 through February 8, while supplies last, with a purchase limit of five units per member.
At its current price, the Predator X27U A1 is among the more affordable QD-OLED monitors available from a mainstream brand. The display features a 2560 × 1440 resolution, a listed 280 Hz refresh rate and a manufacturer-specified 0.03 ms GtG response time. It also supports AMD FreeSync Premium Pro, which allows compatible GPUs to synchronize frame output with the panel’s refresh cycle and enables HDR playback within the FreeSync framework.
According to Acer’s specifications, the QD-OLED panel covers 99% of the DCI-P3 color space and is rated for up to 1,000 nits peak brightness in small HDR highlights, alongside VESA DisplayHDR True Black certification. Typical SDR brightness is listed at 250 nits.
The Predator X27U A1 is equipped with two HDMI 2.1 inputs and one DisplayPort 1.4. The monitor also includes a pair of built-in 5 W speakers and an adjustable stand supporting height, tilt and swivel, alongside a 75 × 75 mm VESA mounting interface.
Within Acer’s broader Predator X27U lineup, the A1 slots below premium models like the newly unveiled Predator X27U F8, which pushes refresh rates to extreme levels at a far higher price. By contrast, the X27U A1 focuses on delivering OLED-level image quality and ultra-high refresh rates at a far more accessible cost.
According to Costco’s product listing, the monitor currently carries a user rating of 4.3 out of 5 stars, based on multiple customer reviews. Customers primarily praised the monitor’s image quality and HDR performance, with several reviews complimenting its OLED panel and the experience when HDR is enabled. Some reviewers also highlighted the presence and configurability of the monitor’s pixel cleaning feature, referencing it in the context of OLED panel maintenance rather than day-to-day performance.
One critical review on Costco’s listing mentions concerns around usability, including the lack of a physical power switch, reliance on software controls for powering the display, and issues with how the monitor is detected in a dual-monitor setup after being turned off and back on. The same reviewer also notes that Acer’s warranty does not explicitly cover OLED burn-in.
