This 280Hz ASUS QD-OLED gaming monitor is under $400, with 1440p and G-SYNC support

A fast QD-OLED gaming monitor for less than $400 is a compelling option if you want better contrast without giving up a high refresh rate. Best Buy has the ASUS ROG Strix OLED XG27ACDMS for $399.99, with a 2560 x 1440 resolution and up to 280Hz refresh rate.

The 26.5-inch monitor is listed new, sold by Best Buy, with shipping available. The retailer showed an Add to Cart button, with pickup and shipping options for Aiea, Hawaii, when checked. Availability can vary by location, and no coupon or paid membership was shown as necessary for this price.

Best Buy compares the price with a $649.99 comparable value, a displayed difference of $250. That figure is the retailer's comparison, not proof the monitor typically sells for $649.99 or that this is a record low. The monitor has appeared at $399.99 before.

What the QD-OLED screen brings to games

The XG27ACDMS pairs 1440p resolution with the deep blacks and contrast characteristic of OLED. Its 280Hz maximum refresh rate can be useful in fast-moving games, provided the PC can produce high frame rates. The refresh rate is not a guarantee that games will run at 280 frames per second; hardware and graphics settings still matter.

The display supports adaptive sync, with Best Buy listing both Nvidia G-SYNC Compatible and AMD FreeSync Premium Pro support. ASUS also lists a 0.03ms grey-to-grey response time, a manufacturer specification rather than a measurement of overall input latency.

ASUS lists DisplayPort 1.4 with display stream compression, HDMI 2.1 and USB-C with DisplayPort Alt Mode and 15W power delivery. Check the source device and cable before choosing a connection. Its adjustable stand supports height, tilt, swivel and pivot adjustments.

Before choosing this monitor

ASUS includes an OLED care suite, including a proximity sensor designed to switch the screen to black when the user steps away. It is still sensible to follow the manufacturer's panel-care instructions and read the applicable warranty terms, especially if the display will spend long hours showing static desktop elements.

At $399.99, this is aimed at a PC player who wants a 1440p OLED with a fast refresh rate. A 4K screen may be a better fit if resolution is the priority, while a conventional LCD can cost less. Check the exact XG27ACDMS model and new condition before ordering; prices and stock can change.
