What the XG27ACDNG gets right
This monitor targets the high-refresh-rate sweet spot: 1440p is considerably easier to drive at very high frame rates than 4K, while 360Hz provides exceptionally smooth motion for competitive games. Its QD-OLED panel adds the deep blacks and vivid wide-gamut color that conventional IPS gaming monitors cannot match.
#1 Best Overall
- QHD Resolution (2560 x 1440) has 1.7 times the pixel density of Full HD for incredibly detailed pinsharp images
- HDR10 provides brighter highlights and nuanced shadow for added depth - making every scene feel more vivid and realistic
- The 180Hz refresh rate minimizes lag for gameplay with ultra-smooth action. Plus, the 1ms response time helps capture your moves in real-time, allowing you to react fast for gaming precision
- AMD FreeSync reduces choppiness, screen lag and image tearing, ensuring that your fast-paced, complex in-game action is stable with minimal stutter
- Ergonomic stand allows for tilt, pivot and height adjustments to maximize gaming comfort
The feature set is broader than many competing 1440p/360Hz OLED displays. HDMI 2.1 makes it more useful with modern consoles and graphics cards, while USB-C video, 90W charging, a USB hub, and KVM support suit a desktop-plus-laptop setup.
Gaming performance
Independent testing from RTINGS finds near-instantaneous response performance, very sharp motion, low input lag, and strong refresh-rate compliance. That makes the XG27ACDNG particularly effective in fast shooters, racing games, and other titles where tracking moving targets matters.
ASUS’s 0.03ms GTG figure is a panel response-time claim, not a complete measurement of total system latency. The practical result is still excellent: OLED pixels transition quickly enough that motion clarity remains strong at 360Hz, provided your PC can produce the necessary frame rates.
Is 360Hz worth it?
360Hz is most useful when you regularly play competitive titles at very high frame rates. It reduces the time between refreshes compared with 240Hz, but the improvement is subtle beside the much larger jump from 60Hz to 144Hz or 165Hz. If your games or GPU normally sit below roughly 240fps, a cheaper 240Hz OLED may provide almost the same experience.
Rank #2
- Quality Visuals: The KG271U 27" IPS monitor with 2560 x 1440 QHD resolution in a 16:9 aspect ratio presents stunning, high-quality images with excellent detail. The zero-frame design does away with the thick frames found on conventional monitors freeing up precious screen space.
- AMD FreeSync Technology: Say “goodbye” to stuttering and tearing. With AMD FreeSync, the monitor’s frames are synced with the graphics card’s frames, which eliminates screen tearing and provide the smoothest gaming experience.
- Up to 180Hz: The 180Hz refresh rate speeds up the frames per second to deliver an ultra-smooth 2D motion scene. With a rapid refresh rate of up to 180Hz, Acer Gaming Monitors shorten the time it takes for frame rendering, lower input lag and provide gamers an excellent in-game experience.
- Responsive!!: Up to 0.5ms GTG (Gray to Gray) response time enhanced gamers’ in-game experience. No matter the fast-moving action or any dramatic transitions will be all rendered smoothly without the annoying effects of smearing or ghosting with KG271U Gaming Monitor.
- New Depths of Color Accuracy: is monitor is ideal for color-critical projects producing accurate colors, supporting DCI-P3 95%. An amazing monitor for graphic designers, photographers, and film editors.
For cinematic single-player games, the panel’s OLED contrast and HDR color are more important than its maximum refresh rate. Do not buy the XG27ACDNG solely because 360Hz is a larger number.
VRR and ELMB
FreeSync Premium Pro and G-SYNC Compatible support help keep the image smooth when frame rates fluctuate. The trade-off is OLED VRR flicker: brightness can visibly change as frame rates move, particularly in dark scenes. If this bothers you, try a frame-rate cap, a fixed refresh rate, or disabling VRR in the affected game. ASUS also includes OLED Anti-Flicker and ELMB features, but their usefulness depends on the refresh-rate range and game; check the on-screen display rather than assuming every mode works together without compromise.
Picture quality and HDR
In a dim or dark room, the QD-OLED panel produces effectively perfect blacks and vivid color. Small bright HDR highlights have strong impact, and HDR gaming looks substantially more dimensional than it does on a typical IPS display.
The important qualification is brightness. ASUS’s headline figure is a peak brightness figure, not a promise of sustained full-screen brightness. A small highlight may become very bright while a large bright scene is considerably dimmer because of OLED power and heat management. The XG27ACDNG’s DisplayHDR 400 True Black certification describes its black-level and HDR behavior category; it does not mean the monitor maintains 1,000 nits across the screen.
Rank #3
- 100% sRGB Color Gamut: With 100% sRGB, our display reveals an astonishing brightness and variance in red, green, and blue color across a wide gamut, providing a more defined and naturalistic display of color in every image.
- DP & HDMI Ports: Two HDMI ports and one DisplayPort port provide up to 100Hz refresh rate, refining picture clarity in all action-packed gaming sequences and graphic design projects. Audio In and a Headphone Jack provide diverse audio options.
- Blue Light Shift: Blue Light Shift reduces blue light, allowing you to comfortably work, watch, or play applications without straining your eyes.
- Built-in Speakers: Perfectly suited to work & gaming settings, built-in speakers deliver robust & smooth audio while saving space on your desk.
- FPS-RTS Game Modes: FPS and RTS are Sceptre's custom set display settings built for an enhanced gaming experience. FPS (First Person Shooter), RTS (Real-Time Strategy).
QD-OLED also has a bright-room weakness. Ambient light can raise the apparent black level and give dark areas a purple or gray cast. The monitor can be usable in an office, but its best contrast is experienced with controlled lighting. If your room has strong daylight or overhead lights, a WOLED or newer brighter OLED may give a more convincing image.
Text clarity and productivity
Text is usable at the native 2560×1440 resolution, but it is not as clean as on a 27-inch 1440p IPS monitor. The QD-OLED subpixel layout can create colored fringing around letters, especially on high-contrast text viewed close up. Whether it bothers you depends on your eyes, operating system, scaling, and viewing distance.
Static desktop use also presents a greater burn-in risk than varied gaming content. The USB hub, KVM, and USB-C input make the monitor practical for switching between a desktop and laptop, but anyone spending all day in browsers, spreadsheets, or fixed application windows should consider an IPS or mini-LED display instead.

Ports, KVM, and console use
The connection layout includes one DisplayPort 1.4 input with DSC, two HDMI 2.1 FRL inputs, USB-C DisplayPort Alt Mode, three USB-A ports, and a headphone output. DisplayPort 1.4 with DSC is sufficient for 1440p at 360Hz, although it is not the same as having DisplayPort 2.1.
KVM lets one keyboard and mouse serve two connected systems, which is one of the monitor’s strongest productivity features. The exact switching behavior and USB upstream requirements depend on the selected inputs and configuration; consult the official manual when wiring the setup.
RTINGS reports compatibility with PlayStation 5, PlayStation 5 Pro, and Xbox Series X|S. The monitor can accept 4K console signals but displays them on its native 1440p panel. That is compatibility with a 4K input, not native 4K reproduction. Console buyers who value maximum sharpness should compare it with a 4K OLED monitor or television; buyers who prioritize high-refresh 1440p play and HDMI 2.1 get a more compelling fit here.
OLED care and burn-in risk
Burn-in remains a possibility when the same static elements are displayed repeatedly. ASUS includes OLED Care+ features and a custom heatsink intended to reduce the risk, but they do not make the panel immune.

ASUS’s U.S. specification page lists a three-year warranty including burn-in coverage. Coverage, exclusions, replacement conditions, and availability may differ by country, so confirm the policy for your region before purchase. No short-term review can establish a precise panel lifespan.
Design, controls, and ergonomics
The monitor offers a practical range of adjustment: up to 120mm of height movement, approximately -5° to +20° of tilt, and 100×100mm VESA mounting. It weighs about 7.44kg with its stand and 4.97kg without it. The stand, OSD joystick, cable routing, and VESA support make it suitable for a conventional desk setup, while Aura Sync lighting provides the expected ROG styling.
The flat 16:9 format is a good match for competitive games and ordinary desktop use. The panel’s surface behavior depends on your lighting, but the central issue is not the styling: it is placing a QD-OLED in a room bright enough to lift its blacks.
How it compares with alternatives

Who should buy the ASUS ROG Strix OLED XG27ACDNG?
- Buy it if you mainly play competitive PC games, can approach 240–360fps, want OLED contrast, and play in a dim or moderately lit room.
- Buy it if HDMI 2.1, USB-C laptop connectivity, KVM, and burn-in warranty coverage are important to your setup.
- Skip it if you need native 4K, maximum full-screen HDR brightness, immaculate IPS-like text, or DisplayPort 2.1.
- Skip it if you work all day with static windows or cannot control room lighting.
- Compare a 240Hz OLED if your games rarely exceed 240fps.
Final verdict
The XG27ACDNG is a strong premium 1440p OLED gaming monitor, not a universal desktop display. Its near-instant response, 360Hz motion, excellent dark-room contrast, HDMI 2.1, USB-C, KVM, and U.S. burn-in coverage create a persuasive package—especially at the $599 promotional price seen on one ASUS page. At $759, the decision depends more heavily on whether you will use the 360Hz refresh rate and connectivity.
Buy it for competitive gaming and a feature-rich PC-plus-console setup. Choose something else for native 4K, bright-room viewing, sustained full-screen HDR brightness, or heavy static office work.
