Compare ASUS ROG Strix OLED XG27ACDNG vs LG 27GX704A-B

The integrated KVM is a practical benefit for using one keyboard and mouse with a desktop and laptop, even if initial configuration is needed.

A KVM switch is absent, limiting convenience for people sharing keyboard and mouse peripherals between systems.

The joystick-based menus offer lots of control and are generally easy to navigate; desktop software adds a more convenient alternative.

A bottom-center joystick works in open setups but becomes hard to reach with another screen underneath. A later owner found wake activation less responsive.

Adjustable Shadow Boost can expose dark gameplay details without excessively washing out highlights.

The black stabilizer can reveal hidden details in dark scenes, a useful assist in competitive games.

Some tests find near-reference accuracy without calibration, while others recommend tuning specific modes for the best sRGB or HDR results.

SDR calibration impresses testers and can become very accurate with simple tweaks. HDR color and tone mapping are less consistent.

It stands out among several QD-OLED competitors in SDR and can deliver striking small HDR peaks, but broad bright HDR scenes remain comparatively dim.

OLED brightness is strong in many games and HDR highlights, but not consistently the brightest among newer Tandem OLED screens. Strong direct light can still overwhelm visibility.

Uniform Brightness can tame distracting changes as windows or bright scenes change, though it reduces peak output. Several tests find the default behavior less intrusive than on rival QD-OLEDs.

Variable peak-brightness settings can change luminance as scene content shifts, so disabling them is preferable for stable production work.

Deep blacks and vivid QD-OLED color create dramatic HDR images, particularly in dark scenes; bright full-screen scenes and some tone-mapping choices are less convincing.

HDR highlights can pop and games look cinematic, but some presets clip detail and Windows HDR can seem dull. Newer OLEDs often offer more saturated HDR color.

Adaptive sync generally keeps games tear-free and responsive, although fluctuating frame rates can introduce OLED flicker and mitigation tradeoffs.

FreeSync and G-SYNC compatibility reduce tearing across changing game frame rates. Variable-refresh flicker can still appear in dark, low-frame-rate scenes.

Its combination of deep blacks, bright accents and vivid color makes both SDR and HDR images exceptionally appealing.

The glossy WOLED screen makes colors, clarity, and true blacks look striking. Its best moments are gaming and cinematic content rather than text-heavy desktop use.

Pixel-level light control delivers exceptionally strong dark-scene contrast and convincing image depth without LCD-style backlight halos.

Pixel-level OLED contrast creates deep shadow areas and bright highlights that stand apart, in dark rooms and under moderate ambient lighting.

Static logos, taskbars and other fixed elements still present a risk of image retention or eventual burn-in, despite the monitor’s protective routines.

After more than 700 hours involving static app interfaces, one owner detected no visible burn-in on test colors.

Fine shadow nuances remain visible alongside bright accents, taking advantage of OLED's pixel-by-pixel light control.

Black levels are naturally deep, but some peak-brightness HDR settings raise dark areas or crush subtle near-black detail.

Small HDR lights pop against true black, while larger highlights can dim or roll off, depending on the mode and content.

Highlights can be vivid, but aggressive presets lose some fine bright detail and compromise the intended contrast.

Third-generation QD-OLED reduces colored outlines around letters, but fine text remains less clean than on a conventional LCD and sensitivity varies.

The WOLED subpixel layout can put colored edges around letters and make them look fuzzy. ClearType helps but does not fully match IPS text.

There is a substantial collection of crosshairs, frame counters, shadow enhancements and custom controls, with more tuning options than several competitors.

Basic features present, viewed as minor extras.

The screen assembly looks and feels sturdy, but opinions split over the more ordinary plastic stand and its fit with the premium ROG aesthetic.

Gloss finish lends a premium look.

Measured white and dark-field uniformity is impressively consistent, with little visible discoloration across the tested panels.

Some faint vertical/gray banding and mesh texture can appear on test patterns. One owner found the issue barely noticeable in normal use.

Racing mode receives praise for natural balance, while certain stylized presets look exaggerated or poorly calibrated without adjustment.

Gamer, FPS, RTS, sRGB, and reading options offer flexible picture tuning, with Gamer 1 singled out as a strong starting point.

1440p at 27 inches looks sharp in games and photographs, but text is not as finely defined as on higher-density 4K OLED displays.

QHD across 27 inches produces a sharp gaming image without needing a larger screen.

Multiple HDR modes make it possible to prioritize peak highlights or a steadier image, but none is ideal for every brightness level.

Gamer 1 and adjusted custom modes can improve HDR, but output varies by preset, operating system, and peak-brightness setting.

Two HDMI 2.1 ports, DisplayPort, USB-C and multiple USB connections form a flexible setup for PCs, consoles and peripherals.

Two HDMI 2.1 inputs, DisplayPort, and USB-A ports serve gaming setups well. USB-C video, KVM and newer DisplayPort standards are missing.

QD-OLED's self-emissive contrast, vivid color and responsiveness are central to the appeal, though brighter rooms can expose its characteristic raised blacks.

Third-generation WOLED brings superb blacks and response, but newer Tandem OLEDs can achieve brighter, more saturated HDR.

The broad QD-OLED gamut produces exceptionally vivid reds and rich colors, with sRGB clamping available when restraint matters more than saturation.

Colors are vivid compared with IPS, yet third-generation WOLED has less HDR color volume than many newer Tandem OLED or QD-OLED rivals.

The illuminated rear logo gives the chassis a distinctive gamer look and offers customizable effects, but it is too subtle to meaningfully light up a wall.

RGB effects are left out of this budget-oriented configuration, a compromise one reviewer accepts.

Controls feel immediate, with measured low processing delay that makes the monitor highly responsive in fast games.

Latency is low and competitive for fast gaming, even if some tests put it slightly behind the quickest OLED rivals. One owner reports a subjective sharpness-setting effect.

Games and photos look crisp at QHD, and VividPixel can assist text; native 4K screens remain sharper for desktop fine detail.

The 1440p glossy screen makes images and games look crisp. Fine text is less clean than on conventional RGB LCD monitors.

QHD strikes a useful balance between visual detail and the frame rates needed for high-refresh gaming, but it cannot match native 4K sharpness.

At 27 inches, 1440p balances sharpness and GPU demands; one PS5 user felt no need to jump to 4K.

OLED contrast and color make story-driven games striking, but 360Hz is often unnecessary and bright-scene HDR can be less compelling than higher-resolution alternatives.

Deep blacks, luminous highlights, and clean motion add immersion to richly detailed story games; HDR accuracy is less reliable across sources.

Three USB-A ports and the upstream connections add useful peripheral access, especially alongside the KVM for a two-computer desk.

Two USB-A ports are handy for wireless dongles and other PC peripherals.

The coating keeps some reflections under control but cannot entirely overcome direct light, and stronger illumination can raise black levels.

The crisp glossy surface also reflects windows and lights clearly. Daytime usability depends heavily on screen position and light control.

PS5 and Xbox can take advantage of HDMI 2.1, 120Hz and compatible VRR/HDR modes, though accepted 4K signals are displayed at native 1440p.

PS5 games can look superb with rich OLED contrast and HDR. A long-term owner experienced recurring PS5 no-signal problems that required power-cycling.

The semi-glossy finish keeps images crisp and colorful without the grain of heavy matte coatings, though it trades off some glare resistance.

The glossy coating is a standout: crisp, low-haze images look substantially cleaner than older matte WOLED finishes.

Colors and contrast hold up impressively from off-center positions, giving a forgiving viewing sweet spot.

Some owners see an impressively consistent image from the side, while a tester notes off-axis red or green tint.

A supplied VESA adapter and standard 100×100mm support make monitor arms and wall mounting straightforward.

Standard monitor-arm mounting offers an alternative to the adjustable included stand.

Routing behind the stand is basic, and one hands-on setup found cables hanging visibly when the monitor was raised.

An included cable clip helps, but the stand lacks a passthrough and the bottom audio jack can leave visible wiring.

High refresh, flexible video inputs and adaptive-sync support suit powerful PCs particularly well, with access to the monitor's full 360Hz speed.

A high-refresh OLED with exceptionally clear motion and deep blacks makes PC gaming the primary strength. The 240Hz panel keeps action responsive.

Truly deep blacks are a highlight in dark rooms, but ambient light can turn them grayish or purple on this QD-OLED panel.

WOLED maintains inky blacks even with room lighting, a notable edge over the purple-tinted blacks sometimes seen on QD-OLED.

The overall experience is strongly praised for fast, gorgeous gaming and abundant features, with lighting, HDR brightness and value providing the principal caveats.

Owners and testers are largely enthusiastic about the exceptional gaming picture and sale-price value. Persistent HDMI handshake trouble and office-use compromises remain important.

The stand feels solid during adjustments, with smooth travel and little reported looseness or wobble.

The metal-footed stand feels sturdy and offers a reassuring base.

Flicker can be visible during fluctuating frame rates in dark games or menus; the mitigation settings may narrow VRR's operating range and cause other compromises.

Flicker sometimes appears when refresh rates fluctuate in dark scenes or even when moving windows; it is not constant in most fast-paced games.

The package is generous, with multiple video and USB cables, cleaning supplies and a mounting adapter that make first setup easier.

HDMI, DisplayPort, USB and power cables give buyers what they need to connect the monitor immediately.

The native 360Hz panel delivers wonderfully fluid motion, especially over 240fps; that advantage shrinks in slower games or on consoles.

The 240Hz refresh delivers noticeably fluid gameplay, although the more expensive 27GX700A-B rises to 280Hz.

Height, tilt, swivel and full portrait pivot are generous and generally smooth, although one assessment finds the maximum height merely average.

A flexible stand supports height, tilt, swivel, and portrait rotation. It even has a slight ergonomic edge over the 27GX700A-B.

ASUS supplies extensive pixel cleaning, shifting and static-logo controls plus burn-in warranty coverage, but none removes the inherent risk of permanent marks.

Pixel shifting and cleaning appear effective in early long-term use, with no observed retention after 700+ hours; this is not a lifetime guarantee.

FreeSync, G-SYNC Compatible and HDMI VRR give good support across modern hardware, though some settings require care to avoid disabling the feature.

Compatible with common PC variable-refresh standards and PS5 VRR, though some use cases expose flicker and a console-signal issue.

360Hz operation, near-instant response and low lag are excellent for shooters and esports when the PC can deliver high frame rates.

Fast OLED response, 240Hz refresh, and a compact 27-inch frame make tracking opponents especially effective.

Moving objects remain clean and well defined, with minimal smearing or overshoot even during rapid action.

OLED response leaves virtually no visible trailing or overshoot in ordinary gaming.

The 1440p resolution is more achievable at high frame rates than 4K, but taking full advantage of 360Hz still demands fast games and a suitably capable PC.

1440p offers a sharp image with substantially lower GPU load than native 4K gaming.

Fast transitions and 360Hz make moving detail look unusually sharp and stable, with little visible smearing.

Rapid motion and moving targets look exceptionally sharp, particularly at high refresh rates. A low-frame-rate user anecdote flags stutter sensitivity.

Near-instant OLED transitions keep action crisp with exceptionally low blur and very little meaningful pixel-response delay.

Near-instant OLED response produces crisp pixel transitions that help fast action look controlled.

Thin top and side borders make the monitor look tidy and help it sit neatly next to a second display.

Thick surrounds are an obvious cosmetic drawback despite the clean picture.

The 27-inch format is comfortable for normal desk gaming, though some users want a larger, higher-resolution option.

The 27-inch format keeps fast games within easy view and fits a desk comfortably, although some consider it small for the price.

The screen housing and mechanical parts generally feel solid; some find the stand's plastic finish less premium than similarly priced rivals.

The stand is solid, but plastic parts feel less premium; the materials fit the monitor’s value focus.

A futuristic ROG rear shell and customizable lighting look distinctive, while the comparatively plain plastic stand divides opinion.

The design is tidy and attractive overall, despite thick bezels and modest plastic material quality.

Flicker-free and low-blue-light options offer flexibility, while OLED anti-flicker settings can help some situations at the expense of VRR behavior.

Reader mode and warmer color settings may help, but one owner experienced substantial eye strain before adapting over months.

Stand parts snap or screw together quickly, and the included mounting adapter eases the move to a monitor arm.

The complete cable package helps, but sliding off the protective foam sleeve makes unboxing clumsy.

A three-year burn-in-inclusive warranty offers reassurance, but actual coverage and conditions depend on the buyer's region.

Coverage terms vary by country, with burn-in exclusions reported in Australia; buyers should check their local policy.

Feature-rich 360Hz OLED performance is appealing at a discount, while full-price comparisons with cheaper 240Hz panels and newer OLEDs require care.

At sale prices around $380–$500, the glossy 240Hz OLED package gets strong value praise. Its higher launch pricing looks less competitive beside newer models.

Full-bandwidth HDMI 2.1 connections are a genuine advantage for modern consoles and PCs, adding flexibility over some competing OLED monitors.

Full-bandwidth HDMI 2.1 helps consoles and gaming PCs use high refresh rates and VRR without the compromises of older ports.

True Black mode can track its target well, but higher-peak modes trade accuracy and brightness behavior, with occasional clipping or dimming complaints.

Tone mapping is imperfect: bright details can clip, while higher peak-brightness settings change darker-scene rendering.

Extensive gamut, gamma, color-temperature and saturation adjustments make the image highly configurable; the best presets differ according to the task.

Multiple picture modes and hardware-calibration support provide useful ways to refine color accuracy.

Some measurements show impressively accurate gamma in the right preset, while others find noticeable errors in several alternative modes.

SDR grayscale and gamma are generally close to target, though some modes and HDR tracking need correction.

A user moving from a TN monitor found low-frame-rate camera pans surprisingly stuttery, despite the OLED’s excellent pixel response.

The OSD joystick sometimes fails to wake or open the menu on the first press, making input changes annoying.

Unusually extensive HDR menus let owners adjust brightness, contrast and color rather than accepting a locked preset; tweaking can alter accuracy.

DisplayWidget offers a convenient desktop interface for settings and shortcuts, making frequent picture adjustments easier than joystick-only navigation.

An expert had a good firmware experience, but a later owner still hoped for a fix to PS5 signal detection.

The standard 16:9 layout avoids awkward game-format compatibility and keeps the full action in view.

Black-frame insertion sharpens motion at 120Hz or 180Hz, but the substantial brightness loss and inability to combine it with VRR or HDR limit its appeal.

Pixel-level OLED illumination keeps bright objects crisp against dark surroundings, without the glowing halos common to some backlit LCDs.

There are no built-in speakers, so console users need headphones or an external audio connection.

Simple SDR adjustments and supported hardware calibration can produce accurate color; HDR tracking still takes more compromise.

A follow-up owner did not notice chrominance overshoot during normal use or controlled sample clips.

The 27-inch flat screen balances gaming immersion with a manageable amount of desk space, and its size is praised as practical for QHD pixel density.

Its OLED black-frame insertion can improve clarity at 120Hz and 180Hz; the loss of brightness, HDR and variable refresh makes it a niche alternative to normal 360Hz operation.

The 10-bit panel delivers fine tonal steps and smooth gradients that complement both gaming and creative work.

The easy-to-reach bottom audio jack leaves a dangling cable when used with external speakers, frustrating tidy desktop setups.

A four-pole headphone connection is described as a useful high-quality audio option, though no listening test is provided.

Sending it 4K for desktop use produces softer text than native QHD, so the higher accepted input resolution is not a substitute for a native 4K panel.

A standard power cable connects directly to the monitor, avoiding a separate external power brick and making cable replacement straightforward.

The included protective packaging is thorough but slightly awkward to dismantle and unpack.

A phone slot in the stand is surprisingly useful and can accommodate even some large handsets with cases.

Photoshop images appear detailed and richly colored, while calibration and sRGB options help make the display suitable for serious image work.

A four-month owner reported no dead pixels after extensive daily use.

An owner found OLED care features effective, while another tester says pixel cleaning can reduce gray-band artifacts.

The integrated power supply uses a standard, easy-to-replace mains cable rather than a proprietary external adapter.

The KVM, docking-friendly USB-C and strong color make light creative and desktop work feasible, despite the static-content tradeoff.

PS5 games can look phenomenal with OLED contrast and high-bandwidth HDMI, although a long-term owner ran into intermittent no-signal failures.

Changing certain HDR or flicker controls can unexpectedly exit HDR and require re-enabling it in the game, a frustrating setup quirk.

The screen sometimes fails to pick up a newly powered-on PS5, and its OSD joystick may need multiple presses after standby.

A top-mounted threaded socket is convenient for placing a compatible microphone, camera or light above the display.

Up to 90W charging is a meaningful convenience for laptops and portable devices and a welcome addition to a fast gaming monitor.

Popular games fit the familiar 16:9 screen without unusual layout or scaling problems.

Four months and 700+ hours brought continued excellent image quality and no burn-in for one owner, despite persistent console connection quirks.

One owner repeatedly encountered a blank PS5 HDMI signal until restarting the display; console modes can also require manual selection for 4K/120Hz.

Individual OLED pixels eliminate the zone-transition and halo artifacts associated with conventional local-dimming backlights.

Viewing more than one source is useful, though some accounts distinguish between available picture-in-picture and missing side-by-side options.

An eye-sensitive owner associated OLED brightness flicker with discomfort, particularly during the first weeks of use.

A tester considers the WOLED glossy surface comparatively scratch-resistant, though no long-term abrasion testing is described.
