If you want OLED-level contrast and instant pixel response, but also want a competitive refresh rate without jumping to 4K pricing, the ROG Strix OLED XG27ACDMS sits in a very “sweet spot”: 26.5” (27-class) QHD QD-OLED, 280Hz, 0.03ms GTG, plus ASUS’ latest panel-protection suite with a Neo Proximity Sensor designed to reduce burn-in risk when you step away. 

Quick highlights

  • QD-OLED + QHD (2560×1440) + 280Hz: a strong combo for esports and cinematic single-player. 

  • 0.03ms GTG + ELMB + VRR (Adaptive-Sync) for clarity and low perceived blur. 

  • HDR10 + up to 1000 nits peak (HDR) with VESA DisplayHDR True Black 400 positioning. 

  • Neo Proximity Sensor + OLED Care Pro: screen goes black when you’re away; includes pixel-cleaning and multiple anti burn-in tools. 

  • Ports you actually need: DP 1.4, HDMI 2.1, USB-C (DP Alt Mode) + 15W PD, plus headphone jack. 

  • 3-year warranty including panel burn-in (region terms apply).

Display & image quality: why QD-OLED at 27” QHD still makes sense

The XG27ACDMS uses a 26.5” QD-OLED panel at 2560×1440 with a 250 cd/㎡ typical brightness and up to 1000 cd/㎡ peak in HDR, paired with OLED’s ultra-high contrast (listed 1,500,000:1). 

For creators and color-critical users, ASUS lists 10-bit color (1.0737B colors), 99% DCI-P3, and Delta E ≤ 2—good signs for accurate grading and vibrant HDR content. 

Best use-case: dim-to-normal rooms where OLED contrast shines. If your room is very bright (sunlight hitting the panel), OLED’s perceived brightness can feel lower than high-end mini-LED IPS/VA.

Motion performance: built for fast aim and fast camera pans

This is where the monitor earns its “Strix OLED” name:

  • 280Hz max refresh and 0.03ms GTG response for extremely clean motion. 

  • ELMB (Extreme Low Motion Blur) is included, aimed at reducing blur/ghosting during fast movement. 

  • VRR (Adaptive-Sync) support, and it’s also listed as G-SYNC Compatible. 

Practical takeaway: If you play Valorant/CS2/Apex at high FPS, QHD + 280Hz is a very real competitive upgrade without the GPU tax of 4K high-Hz.

OLED Care Pro + Neo Proximity Sensor: the standout “daily-life” feature

OLED is stunning, but burn-in anxiety is real—especially with static HUDs, taskbars, and long desktop hours. ASUS’ OLED Care Pro adds multiple protective tools, and the headline feature here is the Neo Proximity Sensor:

  • It detects your distance/presence and switches to a black screen when you step away, then restores instantly when you return. You can also customize detection distance. 

  • It also includes pixel cleaning (automatic recalibration after several hours), screen move, taskbar/logo detection, dimming controls, etc. 

If you’re buying OLED for PC + productivity, this matters a lot.

Who should buy the XG27ACDMS?

Buy it if:

  • You want OLED contrast + 280Hz for competitive gaming.

  • You play in QHD and want high FPS without upgrading to a flagship GPU.

  • You want burn-in protection features that actually fit daily use (presence detection + care suite). 

Consider alternatives if:

  • You work in a very bright room all day and want higher full-screen brightness.

  • You need more HDMI ports (it lists 1× HDMI 2.1). 

Setup tips (quick wins)

  • Use DisplayPort 1.4 for best PC refresh-rate behavior. 

  • Turn on VRR/Adaptive-Sync in GPU settings for smoother frame pacing. 

  • Enable OLED Care Pro features (especially if you use taskbar / static UI daily). 

  • For HDR gaming: enable HDR in Windows only when needed; fine-tune in-game HDR sliders.
