ASUS ROG Strix OLED XG27ACDNG gaming monitor 27" QHD QD-OLED 360 Hz

An OLED panel has no backlight: each pixel emits its own light and switches off completely in black areas. That is where the quoted 1,500,000:1 contrast comes from, and why black is genuinely black rather than dark grey. QD-OLED adds vivid colour, with 99% DCI-P3 and 135% sRGB coverage and 1.073 billion colours. As a result the monitor works for photo and video editing as well as for gaming.

A refresh rate of up to 360 Hz and a 0.03 ms gray-to-gray response time mean crosshairs and opponents move smoothly and without blur. G-SYNC Compatible and AMD FreeSync Premium Pro synchronise frames with the graphics card across a 48–360 Hz range, so the picture does not tear. OLED Anti-flicker, with three settings, reduces flicker when the frame rate fluctuates, and players used to smaller screens can switch to a 24.5-inch or 4:3 image.

The main concern with OLED is burn-in when the same image stays on screen for a long time. The XG27ACDNG has a custom passive heatsink and vents along the top of the rear cover that keep the panel cooler. ASUS OLED Care+ software offers a set of protection functions, adjustable with the mouse through DisplayWidget Center instead of the on-screen menu. Uniform Brightness keeps brightness consistent even when large white windows change size.

A gaming PC connects over DisplayPort 1.4 with DSC compression, while consoles and other devices use the two HDMI 2.1 ports with HDCP 2.2 support. The USB-C port supports DisplayPort Alt Mode and supplies up to 90 W, so a laptop gets picture and charging through one cable. A built-in USB 3.2 Gen 1 hub adds three USB-A ports for peripherals. There are no speakers; audio goes out through a 3.5 mm headphone jack.

The stand tilts 20° back and 5° forward, swivels 45° each way, pivots the screen 90° into portrait and offers 120 mm of height adjustment. The small base leaves more room for keyboard and mouse and has a groove to prop up a phone, and a tripod socket on top of the monitor takes a streaming camera. It weighs 7.44 kg with the stand and 4.97 kg without, and the VESA 100 × 100 mm pattern lets you put it on an arm.

Competitive shooter players who need 360 Hz and a 0.03 ms response time; gamers who want the deep blacks and vivid colours of OLED; streamers who will use the tripod socket and the compact base; and photographers and video editors who use one screen for both work and play and value 99% DCI-P3 coverage.
