Compare ASUS ROG Strix XG27ACS vs HyperX OMEN OLED 27q

The stand is straightforward to assemble, and the joystick-controlled menus make everyday adjustments easy.

The basic software and straightforward menus make common adjustments approachable without a steep learning curve.

Dark scenes look noticeably gray rather than inky black. The limitations are particularly apparent beside VA, mini-LED, and OLED displays.

Dark scenes reveal rich, inky blacks that LCD monitors struggle to match, particularly in dim rooms.

The self-contained power supply avoids an external brick, but the sealed design is a drawback if power components ever need service.

The internal power supply removes the bulky external brick that often clutters a gaming desk.

The IPS LCD avoids the burn-in worry associated with OLED screens, a reassuring advantage for static desktop elements.

Long periods of static HUDs and interface elements remain a concern. The coverage discusses burn-in risk rather than proving a failure on the tested unit.

SDR material looks unusually accurate even with HDR mode active, minimizing the need to swap Windows display modes.

HDR operation is straightforward but starkly limited to on or off, without much scope to tune the image.

Colorful adventures look impressive, but dark cinematic scenes suffer from gray blacks and modest HDR. Better-contrast rivals suit this style more.

Deep shadows, vivid scenery, and smooth camera motion suit atmospheric adventures, racing, and RPGs very well.

The matte finish usually keeps reflections manageable, but direct sun or strong daylight can still wash out the image.

Reflections and bright windows can be a problem, although one demonstration finds the coating softens indoor light reflections effectively.

QHD on a 27-inch panel renders game interfaces and everyday text clearly, though fine detail is below native 4K.

Games and movies generally look crisp at 1440p, while small text and fine details reveal the limitations versus 4K.

The 1440p image and variable refresh support make it appealing for responsive console play, but HDMI 2.0 and the absence of 4K limit the experience.

HDMI 2.1 and 1440p/120Hz capability make the monitor an appealing match for PlayStation and Xbox consoles.

Both major PC adaptive-sync ecosystems are supported, helping reduce tearing without demanding one graphics-card brand.

FreeSync and G-SYNC support generally work well, though one embedded user comment reports G-SYNC trouble over HDMI.

The default overdrive setting produces very little ghosting or overshoot across refresh rates. Pushing overdrive too hard can introduce inverse trails.

Rapid OLED response largely eliminates trails and smearing during sudden camera movement.

DisplayPort, HDMI, and USB-C video provide useful flexibility, but a single HDMI on some configurations and missing USB-A hub limit elaborate setups.

Two HDMI 2.1 inputs and DisplayPort cover typical display connections, but the absence of USB hub functions feels restrictive.

Several owners appreciate the solid finish, while others find the conventional plastic construction and chunky body clearly budget-minded.

Despite its budget positioning, the materials feel more substantial than a typical cheap gaming monitor.

The matte coating contains moderate grain, a small clarity tradeoff for its anti-reflection properties.

Indoor lighting reflections are softened enough to keep the image looking clear in one hands-on demonstration.

Height, swivel, tilt, and portrait pivot are repeatedly praised for comfort and flexibility. A few find the maximum height a little short.

Height, rotation, and tilt adjustments provide good versatility, though limited forward tilt can make close viewing awkward.

A cutout in the adjustable stand provides a practical way to route cables and keep the desk tidier.

Avoiding a separate power brick leaves a tidier set of cables behind the monitor.

The wide color range makes games and images lively, though coverage is more conventional than high-end quantum-dot or OLED alternatives.

Colors are generally vibrant, with wide gamut coverage useful for gaming and creation. One comparison finds them slightly less vivid than some other QD-OLED rivals.

The conventional 16:9 screen is a comfortable fit for desktop and PC gaming, without the width or special layout of an ultrawide.

The traditional widescreen format works well for competitive games, though it offers less lateral immersion than ultrawide screens.

The lack of onboard speakers is disappointing beside similarly equipped alternatives, especially for a simple all-in-one desk setup.

No internal speakers are included; external speakers or a headset are necessary for sound.

Crosshairs, FPS indicators, shadow adjustment, color modes, and adjustable blur reduction offer useful gaming customization.

The included presets strike a reasonable balance between FPS/RPG settings and color-oriented creator profiles.

The 2560×1440 resolution strikes a well-liked balance between crisp visuals and manageable GPU demands at 27 inches.

QHD is a productive compromise for high-frame-rate gaming, but it cannot supply the fine detail of a 27-inch 4K panel.

Standard 100×100 VESA support gives buyers the option to replace the supplied stand with an arm or wall mount.

Arm mounting offers a practical way around desk wobble or an awkward stand angle.

A 1440p, 180Hz IPS panel with adaptive sync fits mainstream PC graphics hardware well, delivering smooth games without the burden of 4K.

The display pairs well with gaming PCs, producing polished results from fast shooters to graphically rich adventures.

IPS viewing angles are broad enough to comfortably share the image, even if off-axis performance is not a class leader.

Colors hold up well when viewed from the side, making the picture less sensitive to seated position.

The overall experience earns strong praise as an affordable, capable gaming setup, especially from owners upgrading an older or 1080p display.

Most assessments recommend it as a rewarding, stripped-back OLED gaming monitor, with brightness and feature omissions being the clearest reservations.

Pixel response is exceptionally quick for this class, with balanced default settings that avoid large overshoot penalties.

Near-instant pixel response virtually removes smearing, making the display especially responsive in action-heavy play.

There are no downstream USB-A ports, making the monitor disappointing as a peripheral hub or simplified docking station.

There is no USB hub, so peripherals need to connect to a PC or a separate dock instead.

Some find the base compact and practical for smaller desks; others consider the deep, heavy stand a substantial space commitment.

A compact 27-inch display fits normal gaming desks more easily than super-ultrawide alternatives.

The 180Hz maximum makes gameplay fluid and responsive for the price, though enthusiasts seeking 240Hz or more may want another model.

The 240Hz panel gives gameplay responsive, fluid motion. Faster flagship OLEDs exist, but the speed is ample for most buyers.

Motion is exceptionally clean for an affordable IPS monitor. ELMB can sharpen fast movement further but adds distracting tradeoffs.

Fast-moving scenes look exceptionally clear thanks to OLED pixel transitions. Racing, shooters, and even desktop scrolling benefit.

Fast pixel transitions, low latency, and 180Hz refresh suit quick multiplayer games particularly well. Extreme esports players may still want higher refresh rates.

Quick OLED response, 240Hz refresh, and compact 27-inch framing suit competitive shooters and esports exceptionally well.

USB-C video input offers a convenient connection for supported laptops and mobile devices, though it is not a full laptop dock.

PC and current-console use are both appealing, especially when an HDMI 2.1 input is available for 1440p high-refresh play.

ELMB can introduce visible red fringing around moving elements even at high refresh rates.

Fine fonts can look fringed or slightly blurry because of the OLED subpixel layout, making close text work less appealing.

Excellent sRGB modes and ample tuning options make accurate colors achievable with little extra work; the calibrated preset restricts some controls.

Colors arrive impressively tuned, but the lack of manual gamma adjustment limits advanced calibration.

DisplayWidget gives convenient desktop control of the monitor, complementing the usable built-in menus.

OMEN Gaming Hub is attractive and easy to navigate, although the monitor offers relatively little to customize.

The DisplayWidget utility provides functional software control, although its value depends on the connected PC and setup.

The companion software makes existing controls easy to reach, but it does not add the advanced features found on more elaborate monitors.

HDMI is limited to version 2.0 and a lower refresh ceiling than DisplayPort, reducing flexibility for demanding console setups.

High-bandwidth HDMI 2.1 is a practical strength for supported PCs and 1440p/120Hz console gaming, and gives it an edge over some cheaper rivals.

One extended hands-on account describes the display as a dependable gaming companion, though broader lifespan claims remain premature.

There is confidence in the HP name, but no sustained durability test establishing how well this panel ages.

Its motion tuning, color accuracy, and ergonomic stand are excellent for the money, especially on sale. Less expensive rivals can be better for HDR or particular features.

It delivers genuinely impressive OLED color and speed at a relatively approachable price. The value is strongest when discounted, though budget LCDs remain much cheaper.

Assembly is easy and factory tuning is strong enough to enjoy games immediately, without a lengthy calibration process.

Assembly is straightforward, with a simple stand connection and no tools needed in one hands-on setup.

IPS contrast leaves shadowy scenes looking gray and washed out. Brighter colorful games flatter this panel much more than dark cinematic material.

Self-lit OLED pixels create striking separation between bright objects and deep shadows, especially in atmospheric games.

SDR brightness is punchy enough for ordinary indoor gaming and many brighter rooms. Turning on ELMB cuts that headroom substantially.

Brightness is the most persistent weakness: adequate for many indoor desks but underpowered beside brighter OLED and mini-LED competitors.

HDR400 can add a little color and brightness excitement, but poor blacks and no local dimming prevent convincing HDR highlights.

HDR can still make colorful scenes impressive, but highlights lack the intensity of stronger HDR monitors. It is not the best choice for HDR enthusiasts.

DisplayPort and USB-C DisplayPort Alt Mode make the fastest refresh settings accessible from compatible PCs and laptops.

DisplayPort can carry the full 240Hz refresh rate, so PC gamers are not confined to HDMI.

FreeSync and G-Sync support help keep gameplay smooth across changing frame rates. Variable overdrive also keeps artifacts in check as refresh falls.

Adaptive sync works across the two major graphics ecosystems in direct testing, even though the monitor menu labels are somewhat confusing.

The joystick and clear menus give easy access to extensive color and gaming settings without excessive button hunting.

Physical controls and menus are easy to navigate, so brightness and input changes require little effort.

Sharp, colorful, well-calibrated SDR imagery is the major attraction. Weak blacks hold it back for dark or HDR-heavy material.

Deep blacks, saturated colors, and remarkably sharp motion make games visually engaging. Limited peak luminance prevents it from leading the OLED field.

Excellent sRGB factory tuning is a consistent standout, with impressive accuracy before calibration. Some default wide-gamut settings can oversaturate standard content.

Factory color calibration wins especially high praise, with natural-looking hues and unusually strong out-of-box results.

The plastic body and sturdy stand generally feel well assembled for the price, even if the materials do not rival expensive flagship monitors.

Rigid construction and a solid metal stand help the hardware feel reassuringly well made.

The 27-inch format feels just right for close desktop gaming and gives QHD content pleasing sharpness.

The 27-inch format is regarded as a gaming sweet spot: large enough for detail yet compact enough for esports.

The restrained front and slim bezels appeal to those who dislike aggressive gaming styling, although the bulky rear and foot divide opinion.

Styling is restrained and desk-friendly rather than flashy. Some like the professional look, while others find it a little dull.

Self-emissive pixels eliminate the visible backlight glow associated with conventional LCD panels.

Bright objects remain crisp against darkness without the glowing halos associated with backlit displays.

The absence of RGB appeals to fans of understated desks but disappoints buyers seeking decorative lighting.

ELMB can make fast motion clearer, especially at high refresh rates. Brightness loss, double images, crosstalk, and red fringing leave opinions sharply divided.

The tested firmware could not be updated, leaving fewer options for future feature or compatibility fixes.

The basics are present, including gaming aids and adaptive sync, but extensive customization and additional hardware conveniences are limited.

A speedrun and countdown timer are handy extras for players who measure attempts or challenge completion times.

1440p is less taxing than 4K, but taking full advantage of 240Hz in demanding AAA games can still require an extremely fast GPU.

The enclosure stays comfortably cool to the touch in use, without drawing attention to heat buildup.

The package is relatively bare, with little beyond the stand and basic cables to get started.

Very low processing delay makes controls feel immediate, including at lower fixed refresh rates.

Unusually effective variable overdrive delivers a reliable one-setting experience. The highest slider levels can create unwanted inverse ghosting.

The fast IPS panel excels at responsiveness and viewing angles but cannot escape its native contrast limitations.

The slot in the base can neatly hold a phone for guides or calls, but large phones may not fit and some find it gimmicky.

Rich, reasonably accurate colors make photo editing a realistic second use, though it is primarily a gaming display.

The screen itself is manageable to handle, but the heavy stand and wide foot can make rearranging a compact desk awkward.

Energy use is typical and reasonably efficient for a 27-inch IPS LCD without costly local dimming.

Readable text and accurate colors make this more than a gaming-only screen, although it lacks advanced workstation connectivity.

A sealed internal power supply and guidance toward professional service make self-repair less appealing.

Brightness and color uniformity are acceptable for games, but testers note some edge variation.

The stand generally feels sturdy but may wobble on a less-solid desk and can lean back awkwardly when placed close.

A threaded mount above the screen offers an unusually convenient place to position a webcam or other compatible camera gear.

USB-C accepts a video signal, but its 7.5W charging output is far too weak for laptop power or an easy one-cable workstation.

Shadow Boost makes dark details easier to see, though pushing those shadows can spoil the atmosphere of some games.

A missing USB hub means it cannot serve as a KVM for sharing keyboard and mouse peripherals between computers.

The HDR label overpromises what the actual edge-lit hardware can deliver, despite otherwise capable motion specifications.

There is no local dimming hardware, so HDR cannot isolate bright highlights from dark backgrounds.

The small USB-C power output cannot adequately power a laptop and offers little beyond light charging for smaller devices.

Factory gamma lands very close to its intended target, preserving natural content brightness without extra calibration.

HDR offers almost no manual adjustment; shoppers wanting fine control over HDR brightness will be disappointed.
