Compare LG 27GX700A-B vs Gigabyte MO27Q28G

Most menus are familiar, but console users may need a less-than-obvious HDMI input-mode adjustment to unlock 120Hz.

Rear joystick controls and practical shortcuts make everyday operation fairly straightforward.

Some tested modes under-track highlights or sacrifice detail for brightness, so HDR precision does not always match the panel’s impressive peak capability.

Small bright details can look spectacular, but some tone-mapping choices dim or crush highlights and reduce the detail they should preserve.

No combined USB-C video-and-power laptop solution means extra cables and separate charging.

USB-C laptop charging depends on Smart PD settings and workload. Reviews range from frustration at low default power to reports of much higher delivery when enabled.

Game imagery looks crisp, although fine desktop print and the matte coating can reduce perceived detail versus 4K or glossy alternatives.

Native QHD looks reasonably sharp in games, while coating grain, scaling and text subpixels prevent the crispness of denser 4K screens.

Two HDMI 2.1 inputs, DisplayPort, USB-A hub ports, and headphones cover straightforward gaming. USB-C and a KVM are missing for more elaborate desks.

HDMI, DisplayPort, USB-C and USB-A give this gaming display a useful mix of connectivity, albeit without a generous peripheral hub.

There are no integrated speakers, so audio needs to come from a headset or separate speakers.

Built-in speakers are useful for basic audio and casual viewing, but bass and richness are limited compared with external speakers.

Some modes lift shadows to improve visibility while others crush them and lose detail. Calibrating the monitor does not always fully solve the issue.

Dark shadow detail can be crushed at high refresh rates or in specific presets, despite the panel’s excellent absolute black depth.

It can handle routine photos after appropriate adjustments, but serious editing is less certain because of gamma, white-balance, and color-accuracy concerns.

Its gamut and glare control are useful for occasional photo editing, but dark midtones and inconsistent uniformity make precision work harder.

Off-axis quality is generally decent, though one direct comparison found colors wash out faster than on an older LG OLED.

Off-axis picture consistency is generally strong for OLED, although some testing finds slight color shifts at extreme viewing angles.

The matte coating is divisive: some see a surprisingly clean image with low glare, while others find its grain and softened highlights highly distracting.

The matte coating can introduce grain and slight image softness; glossy alternatives appear clearer in a controlled dark room.

Per-pixel OLED blacks make dark environments exceptionally deep, including under ambient lighting. Some picture modes lift or crush near-black tones.

The OLED panel produces genuinely inky blacks and convincing depth without the gray glow associated with conventional LCD backlights.

The heavy metal stand keeps the screen firmly planted even during competitive play, despite its somewhat bulky appearance.

Most testers find the thin stand unexpectedly firm, though at least one describes it as flimsy.

Gray bands and dirty-screen patterns can be visible, particularly in dim scenes and on dark-mode backgrounds; experiences differ notably across panels.

Dark-gray vertical banding, uneven shades and occasional red tints are the most consistently reported panel weaknesses.

Judgments vary sharply: several testers call it a favorite gaming OLED or an excellent sale purchase, while one strongly rejects its HDR tuning and grainy coating.

Most assessments recommend this as an unusually capable and affordable OLED gaming monitor; a few give more weight to coating, brightness or uniformity problems.

One take appreciates the compact flat base for small desks, while another finds the heavy stand disproportionate. Placement depends on available space.

The small, thin metal base frees room for keyboards and other desk gear without sacrificing much stability.

Pixel-shifting protection is useful, but long periods of static taskbars and editing interfaces still warrant care with OLED ownership.

Gigabyte supplies pixel cleaning, logo dimming, shifting and other OLED Care controls. These are helpful safeguards, not a guarantee against wear from static images.

1440p is practical at 27 inches and less taxing for games than 4K, but fine text is visibly softer than on similarly sized 4K monitors.

QHD at 27 inches provides useful desktop space and decent clarity, but cannot match the text and fine detail of 4K.

The clean UltraGear styling and stable stand help it look and feel like a high-end gaming display.

The metal base, slim stand and restrained styling give the chassis an unexpectedly high-end impression.

The matte treatment significantly reduces mirror-like reflections and preserves black depth in bright rooms. The tradeoff is occasional diffuse haze or grain.

The matte anti-glare finish reduces mirror reflections and preserves blacks under ambient light. It trades away some of a glossy panel’s crispness.

PlayStation support is generally strong, including high-refresh operation from accepted 4K signals. Xbox Dolby Vision is absent, and some console setups require changing HDMI compatibility settings.

Console support includes 120Hz options and 4K downscaling, with HDMI bandwidth and chroma-format tradeoffs to consider.

Deep blacks and bold light effects make atmospheric adventures immersive, but lower-frame-rate games do not exploit the 280Hz ceiling and HDR can be inaccurate.

Cinematic games benefit from dark blacks, striking HDR effects and rich color, although aggressive peaks can mask some subtle details.

The new subpixel arrangement reduces intrusive color edges around text, but small type can still look softer than on a high-resolution LCD.

The revised subpixel layout improves text over older WOLED designs, but visible fringing remains around lettering and flat-color edges.

The 280Hz refresh, exceptionally quick pixel response, and low lag make competitive games feel immediate and clear. Even faster esports models exist for players prioritizing refresh above image quality.

Fast response and low lag help competitive players track motion and place shots precisely. Reaching the full 280fps requires sufficiently fast hardware.

Near-instantaneous OLED pixel changes are consistently praised for clear, immediate gameplay.

Near-instant OLED response times give the screen precise moving detail and excellent high-speed gaming behavior.

Low input lag makes both PC and console controls feel highly responsive, matching the quick OLED pixel transitions.

Input lag is exceptionally low at high refresh rates, giving clicks and camera movement a responsive, connected feel.

At 280Hz, gaming feels notably smoother and motion is clearer than at mainstream refresh rates. A few premium alternatives go even faster.

A 280Hz ceiling is fast enough for smooth, competitive play, although the improvement over 240Hz is smaller than the gap to high-end 480Hz-plus models.

The 1440p picture looks sharp for gaming while remaining easier to run than 4K, though it is not the best match for ultra-fine text.

1440p is a practical match for high refresh rates and midrange gaming PCs, though 4K is noticeably sharper.

Several testers noticed brightness flicker when frame rates fluctuated, particularly in dark games. One sample had little obvious flicker, so severity varies.

Rapid or large frame-rate changes can cause noticeable VRR flicker, especially in dark scenes; anti-flicker settings help but are not a complete cure.

The expanded gamut brings richly saturated colors and strong HDR color coverage, representing a clear improvement over older WOLED generations.

Wide DCI-P3 and expanded BT.2020 coverage give games, movies and creative work rich color. Proper gamut clamping is important to avoid exaggerated SDR saturation.

Fast movement stays sharp and readable at high refresh rates, with the near-instantaneous OLED response a consistent gaming highlight.

Fast OLED transitions and 280Hz operation deliver excellent motion definition. Higher-refresh premium models still offer incremental gains.

Bright objects appear against deep blacks without the glowing halos commonly seen around LCD backlight zones.

Individually lit pixels prevent the halos and blooming found around bright objects on many locally dimmed LCD screens.

Gaming picture modes offer useful flexibility, but their gamma, saturation, and HDR accuracy vary substantially. Choosing the wrong preset can compromise shadow detail.

Standard and gaming-oriented picture presets cover different uses, though the special modes are not necessarily more accurate than well-tuned standard settings.

Near-instant OLED response leaves fast motion unusually free of trailing and ghosting in action games.

Fast OLED pixel transitions keep moving edges remarkably free of smearing, ghost trails and overshoot artifacts.

Running pixel-clean cycles may soften gray-band artifacts on some Tandem OLED panels, but they are not a guaranteed cure.

Pixel refresh can reduce some visible banding, although it does not always fully correct it; cleaning cycles are also part of OLED protection.

Height, tilt, and swivel flexibility are praised; one comparison finds a glossy LG sibling slightly more ergonomic.

Height, tilt, swivel and portrait adjustments provide versatile ergonomics from a compact metal stand.

There is no integrated KVM to share keyboard and mouse between computers. Hybrid desk setups need external hardware or a different monitor.

The KVM makes sharing a keyboard and mouse between two connected computers convenient, with input switching designed around multi-device desks.

Brightness behavior varies by scene and setting. Some gaming tests found little distracting dimming, though switching bright windows and larger HDR highlights can expose limits.

Larger bright scenes can trigger dimming, especially in more aggressive brightness modes. The more uniform SDR settings are less distracting for desk work.

Accessing 120Hz over HDMI can require manually selecting the proper AV compatibility mode before the option appears.

At least one test found VRR could stop working when changing HDMI and DisplayPort inputs, reducing confidence in seamless mode switching.

There is strong HDR impact and deep contrast, but major disagreement about real-game brightness and accuracy. Very bright settings sometimes overexpose the image or crush dark detail.

Deep OLED blacks and impressive highlights make HDR gaming particularly striking. Full-screen brightness, dark-scene detail and preset accuracy are less consistent.

Black Stabilizer can lift visibility or help adjust shadow tones in dark games, although it cannot completely repair underlying HDR tracking errors.

Dark-scene adjustment can uncover otherwise hidden shadow details, although aggressive settings lift blacks and alter the intended image.

True OLED blacks deliver striking image depth and contrast without blooming. Some inaccurate presets alter perceived black detail despite that panel strength.

Per-pixel OLED control gives dark scenes exceptional contrast and an immediate transition from black to bright highlights.

The OSD remains familiar and reasonably approachable, with accessible brightness, picture, and OLED-care settings.

The joystick-led menu and software controls are generally easy to navigate, but placement of APL controls and some locked options frustrate.

SDR sRGB accuracy earns praise from some testers, while others report substantial white-balance and gamma errors. HDR accuracy is especially contentious without careful adjustments.

Factory color accuracy ranges from good to merely fair depending on preset and sample. Grayscale tint, dark gamma and calibration effort are the main reservations.

DisplayPort 1.4 handles the native high-refresh mode but lacks the newer 2.1 connectivity found on some premium alternatives.

DisplayPort can drive the native high-refresh mode with compression, while turning compression off forces significant signal compromises.

Rich color, perfect blacks, and unusually sharp motion make games visually impressive. Grading inaccuracies, gray bands, and a grainy matte finish can take away some of that impact.

Games and video look bold and dimensional thanks to strong contrast and rich color, though individual units and presets can have visible tonal faults.

The fourth-generation Tandem OLED panel often looks brighter than older WOLED monitors, especially in SDR and very small HDR highlights. Not every tested game or HDR setting delivers the expected peak.

SDR brightness is a major strength for this OLED generation, and small HDR highlights can be dazzling. Broad bright scenes and specific modes show more modest results.

FreeSync and G-SYNC compatibility keep motion fluid across supported PCs. Large frame-rate swings can still produce visible flicker in dark scenes.

FreeSync and G-SYNC generally keep motion smooth, with some settings designed to tame frame-rate swings. Adaptive sync still shares OLED’s potential for visible flicker.

Tandem OLED makes bright, saturated colors more convincing than older WOLEDs, but QD-OLED alternatives can still deliver stronger color luminance.

The newer Tandem panel delivers much greater saturation and color purity than earlier WOLEDs. Very bright saturated HDR colors can still trail QD-OLED alternatives.

The shorter two-year warranty is a disadvantage beside commonly available three-year OLED alternatives.

Three-year coverage that includes OLED burn-in offers welcome reassurance for a panel with known static-image wear concerns.

HDMI 2.1 supports modern console and high-refresh connections, but one hands-on setup needed an input compatibility change before 120Hz worked.

HDMI 2.1 inputs support high refresh rates but use a limited 24Gbps link rather than full bandwidth; DSC is needed for the richest 280Hz signals.

At around the strongest sale prices, fast Tandem OLED performance looks compelling. At launch-like pricing, the omitted docking features and picture compromises are much harder to forgive.

Tandem OLED brightness and fast gaming performance arrive at a comparatively approachable price, making value one of the strongest selling points.

Tweaking HDR settings can improve tracking, yet even after adjustments some dark details and highlights remain inaccurate.

HDR adjustment controls is useful under the described circumstances, though performance depends on the chosen settings.

HDR tracking is among the biggest drawbacks: modes often brighten the whole image or crush shadows, and adjustments can trade accuracy against spectacular highlights.

HDR tracking varies substantially by mode; the conservative preset is generally more faithful, while high-output options alter highlight or midtone levels.

The chassis feels sturdy and thoughtfully built, with substantial support behind the display.

The slender metal stand and stable construction earn praise, although one review found the assembly rather light and flimsy.

The UltraGear styling is smart and premium-looking, with restrained lines and accent lighting; the substantial base may look oversized to some.

Slim bezels, a low-profile base and restrained metal accents make the design neat and unobtrusive. Some find it plain rather than stylish.

The coating, improved text presentation, and stable white appearance make longer reading and office sessions less tiring than on some earlier OLED designs.

Brightness controls, low-blue-light alternatives and flash dimming can make long or dark-room sessions easier on the eyes, though flicker-sensitive users may still notice OLED behavior.

Gamma is a recurring weakness: brighter-than-intended midtones and some poorly matched presets can require full calibration to correct.

Dark gamma and black crush appear in some factory modes. Changing gamma or choosing a more accurate color-space preset can recover detail.

The programmable Tactical Switch makes reduced-size displays easier to call up for competitive play, although these emulation modes require some setup and can introduce scaling compromises.

The Ultra Clear black-frame mode improves perceived sharpness at 120Hz, but it cannot be combined with VRR or HDR and carries brightness and flicker compromises.

Rear accent lighting adds some flair and was reported working correctly during hands-on testing.

A cable clip tidies the connections, but the external power brick and limited integrated routing can still leave clutter to manage.

The monitor works with modern gaming PCs and several other source types, but particular ports and modes impose bandwidth limitations.

Firmware updates improved launch-era color and HDR behavior, so checking the installed version is important for getting the reviewed performance.

Crosshairs, timers, hardware overlays and configurable shortcuts give this gaming monitor a capable toolkit, even if some extras are niche.

The 1440p resolution is easier to drive at high frame rates than 4K, though taking full advantage of 280Hz still calls for a capable gaming PC.

Dark-gray banding and patchiness can interrupt otherwise smooth shading. Pixel maintenance may help but does not consistently eliminate it.

Multiple HDR presets offer a useful choice between accuracy and impact. The most aggressive 1500-nit options introduce saturation or tone-mapping compromises.

The headphone output is a welcome fallback when the modest built-in speakers are not sufficient.

The headphone jack with DTS processing earned a positive listening impression; a separate headset is still needed for sound.

Scaling lower-resolution signals is serviceable but not always sharp; the strongest enhancement settings can look artificially processed.

The supplied cables, mounting hardware and power accessories support a fairly straightforward initial setup.

An external power adapter can be replaced without opening the screen, though it adds a separate item to cable management.

The black-frame-insertion feature can make 120Hz motion look noticeably clearer, at the cost of brightness and simultaneous VRR operation.

OLED removes the need for conventional overdrive tuning and avoids the overshoot artifacts seen on some LCDs.

The fourth-generation Tandem WOLED brings meaningful gains in brightness and color, but retains some WOLED uniformity and color-volume shortcomings.

High-refresh PC play is a clear strength, combining GPU-variable-refresh support with low lag and crisp motion.

Brightness values and certain settings are not always remembered independently when toggling display modes, creating extra adjustments.

The thin, relatively light assembly is easy to position and move, even if it feels less substantial than some heavier designs.

A conventional replaceable mains lead is easier to manage than a proprietary built-in connection.

The display can handle occasional office tasks alongside gaming, but OLED wear and imperfect text edges discourage all-day static work.

One owner reports that Windows HDR does not automatically revert to SDR as expected, requiring a manual toggle between games and desktop.

The speakers are passable for basic listening but sound thin and lack bass; external audio is the better choice for music or gaming.

Speaker volume control has useful range for quiet evenings as well as ordinary daytime listening.

The USB hub and KVM are convenient for basic peripherals, but two downstream ports can feel limiting.

PC and console VRR support is broad, though unstable frame rates can reveal gamma flicker and some input-switching quirks.

DTS Headphone:X processing is appreciated as a useful option for headphones connected to the display.

APL Stabilize offers a choice between steadier brightness and punchier highlights. Higher settings can produce noticeable luminance shifts as on-screen content changes.

Display Stream Compression enables full refresh rates over limited-bandwidth inputs. Users who want compression disabled face lower refresh or color-format ceilings.

A critical account objects to the HDMI 2.1 label because the ports lack full bandwidth and need compression for certain high-refresh formats.

Self-emissive pixels provide precise local control rather than coarse backlight zones, avoiding halos in mixed bright and dark scenes.

The passive design avoids the distraction of an audible cooling fan.

Color-space presets, gamma options and RGB adjustments offer useful tuning. Some emulation modes lock controls, and correcting darker tones can take experimentation.

Gigabyte’s desktop utility is useful for configuration and firmware, with some setup requirements and occasional preference for competing software.

Menus and current firmware seem functional, though a critical tester felt substantial updates were needed to improve the picture.

The lack of Dolby Vision limits Xbox HDR flexibility compared with monitors that support that format.

Near-black banding can change after the first weeks of ownership, with some panels improving and others still showing it. Unit variation is an important uncertainty.

Slim, largely flush bezels make the picture dominant without an overly chunky bottom edge.

The 27-inch size is comfortable for QHD gaming and desk use, balancing workspace with manageable system demands.
