Compare LG 27GR83Q-B vs ASUS ROG Strix Pulsar XG27AQNGV

The absence of strobing is a disappointment for gamers wanting the sharpest possible moving images at 240Hz.

G-SYNC Pulsar delivers unusually clear motion while keeping VRR active, including at midrange frame rates. Small double-image artifacts and low-frame-rate cutoffs prevent perfection.

The matte coating helps in brighter surroundings while leaving the image reasonably clean and clear.

The matte surface softens perceived crispness compared with a glossy OLED, particularly when reflections are diffused across the display.

Two HDMI 2.1 connections, DisplayPort, USB-A, and audio output cover gaming essentials well, but the missing USB-C dock-style input restricts work use.

Two HDMI 2.1 ports, DisplayPort, and USB-A cover basic gaming needs, but the lack of USB-C and KVM disappoints in this price class.

The V-shaped stand can take more desk depth than compact alternatives, although one tester finds the legs less intrusive than expected.

The compact metal base leaves notably more space for mouse swipes and keyboard placement than bulkier gaming stands.

Fast gaming is clearly its priority; office-oriented rivals can offer more convenient connectivity and switching options.

The screen is a capable secondary or everyday productivity display with clean text and enough usable screen space for common workloads.

PS5 and Xbox owners benefit from strong HDMI compatibility, 120Hz support, VRR, and useful 4K-input downscaling. HDR quality remains the main console caveat.

HDMI 2.1, VRR, and 120Hz input work well for consoles, including virtual 4K signal acceptance. The native panel remains 1440p and console users cannot access 360Hz.

A light matte finish suppresses reflections effectively without making the picture overly grainy.

The matte coating limits obvious reflections, although diffuse glare can reduce perceived contrast and crispness.

Rear connections are easy to find but not always convenient for frequently unplugged accessories, resulting in mixed assessments.

Recessed rear connections can be fiddly, especially with bulky plugs or frequent cable swaps.

The IPS panel holds its image well from the sides, making shared viewing more comfortable than on many VA competitors.

IPS offers respectable off-axis stability versus TN, though familiar IPS glow and a few weaker impressions limit dark-scene viewing.

Games and text look crisp at the 27-inch QHD pixel density, making the step up from 1080p worthwhile.

QHD on an RGB-stripe IPS panel keeps game detail and text crisp; matte diffusion is a small compromise against glossy alternatives.

Wide-gamut coverage brings vivid color, with sRGB limiting available when accuracy matters more than saturation.

Colors are pleasantly vivid for IPS and suitable for gaming, but P3 coverage and saturation trail several premium OLED and wide-gamut rivals.

The FPS and RTS presets are seen as gimmicky by one owner, who prefers choosing settings manually.

Racing and sRGB choices cover different looks, but one dedicated sRGB preset locks brightness; switching the color-space option offers more flexibility.

1440p is easier to drive than 4K, but approaching 240fps in demanding games still calls for a capable graphics processor and CPU.

Pulsar offers high effective motion clarity without the enormous rendering load of 540Hz or 720Hz gaming. It still benefits from a system capable of high frame rates.

Story-driven games can still look good in SDR, but dark-scene contrast and weak HDR blunt their cinematic impact.

Vibrant worlds and sharp motion work well for immersive single-player games, but some prefer OLED for darker scenes, richer HDR, and cinematic contrast.

Standard 100×100mm mounting and a positive firsthand arm-mounting account make it straightforward to free up desk space.

Standard 100×100 mounting offers a useful alternative to the sometimes stiff or height-limited included stand.

FreeSync and G-SYNC compatibility work well across differing frame rates, giving gamers tear-free play without major reported disruptions.

Variable refresh operates broadly and can run alongside Pulsar on NVIDIA systems; an early owner experienced some game-specific disruptions.

Crosshairs, a frame-rate counter, and black stabilizer cover the common gaming extras, though the selection is not especially expansive.

Crosshairs, frame counters, timers, image presets, and competitive viewing options provide practical extras around the core high-speed display.

1440p is a satisfying middle ground between crisp detail and attainable high frame rates, especially on a 27-inch screen.

The 2560×1440 picture strikes a useful balance between desktop detail and attainable gaming frame rates, although it cannot match 4K or 5K text sharpness.

The Fast overdrive mode contains inverse ghosting well, but maximum settings can introduce visible overshoot.

Moving objects are exceptionally clean across the panel, though faint crosstalk or double images can occur in particular colors or during sudden frame-rate changes.

The pixel density is noticeably finer than a comparably sized 1080p monitor, improving text and small in-game details.

At about 109ppi, QHD text and everyday images look clean while remaining readable without aggressive scaling.

Pixel transitions generally keep pace well with fast play, although technical tests find the claimed 1ms figure optimistic and tuning less ideal at the refresh-rate extremes.

Pixel transitions are very fast for IPS and contribute to remarkably clear motion, even though OLED retains an inherent response-time advantage.

Height, tilt, and portrait pivot are useful, but swivel is absent; one assessment describes broader adjustments, so physical flexibility is not completely agreed upon.

Tilt, swivel, height, and pivot are available, but samples vary: some reviewers describe very stiff rotation and height limitations.

There are no internal speakers, so a headset or separate audio setup is needed for sound.

There are no internal speakers. The headphone jack helps, but this omission is frustrating at the asking price.

Fast generally works best at medium and high refresh rates, while Normal is preferable around 60Hz; the most aggressive setting sacrifices visual cleanliness.

The extensive overdrive adjustment and effective variable tuning offer clean transitions; aggressive settings can introduce visible pale halos.

With sRGB adjustments or calibration, colors can become accurate enough for serious photo work even though it is primarily a gaming screen.

Photoshop and light image editing feel comfortable on the sharp, reasonably accurate panel, though it is not a wide-gamut specialist.

Blacks are relatively shallow compared with VA, mini-LED, and OLED displays; dim scenes may look gray rather than deep black.

Blacks often look elevated or gray, especially in dark rooms. This IPS display cannot match OLED depth.

Its 240Hz operation is a major draw, noticeably smoothing fast games compared with 144Hz or 165Hz displays when the PC can supply enough frames.

The 360Hz refresh rate is excellent for a QHD IPS monitor and especially effective with high-frame-rate games. Full speed requires DisplayPort.

Testing reports clean VRR behavior without noticeable flicker, including with adaptive sync engaged.

Changing frame rates usually produce very little visible flicker. Frequencies near the lower Pulsar threshold can still be sensitive.

Fast-moving objects remain clear and fluid at high refresh rates, with a few testers noting OLED or premium strobed LCD alternatives can look sharper.

Remarkably sharp motion across nearly the entire panel is the defining strength, even at frame rates far below 360fps. Minor strobe crosstalk remains in some situations.

Two USB-A downstream ports serve simple peripherals, but the upstream connection is USB-B and there is no convenient USB-C docking solution.

The three USB-A connections are useful for accessories, even though the monitor offers no USB-C docking.

240Hz, low latency, and good motion tuning are particularly persuasive for esports and fast shooters. Running close to 240fps makes the most of it.

Among its clearest strengths are fast response, very low lag, 360Hz refresh, and crisp Pulsar motion. It is especially rewarding for fast competitive play on NVIDIA PCs.

This is a strong fit for modern PC gaming, especially fast titles with capable graphics hardware and DisplayPort or HDMI 2.1 output.

DisplayPort-connected NVIDIA PCs get the most complete feature set, while the GPU and input restrictions can frustrate more complicated arrangements.

Controls feel immediate, and measured processing delay is consistently very low. That makes fast reactions one of the monitor's most convincing strengths.

At high refresh rates, input response is exceptionally quick. Fixed-rate 60Hz ULMB introduces more delay than the normal gaming mode.

A dependable, fast 1440p gaming monitor that earns broad approval for responsive play. The limited HDR image and changing sale prices are its recurring qualifications.

The overall gaming experience earns exceptional praise for motion and responsiveness; one enthusiastic owner still returned an early unit because of defective pixels.

The IPS panel gives pleasing speed, bright SDR output, and broad viewing angles, at the cost of OLED-like blacks and contrast.

Ultrafast IPS blends high-speed motion with stronger color and viewing angles than traditional esports TN screens. It cannot provide the OLED contrast that cinematic content benefits from.

The standard base feels secure despite its broad legs, with testers generally describing sound construction.

The sturdy compact base often stays firmly planted, although one test reported moderate wobble when moving the screen or pressing controls.

Fast menu response and reliable PC-to-console input changes are strengths, aided by configuration options for sleep behavior.

During early play, Pulsar sometimes turned itself off and back on unexpectedly in borderless games. The owner said the problem stopped after the first day.

SDR picture quality is attractive and sharp for the price, especially in bright games, with the expected IPS limitations in dark material.

Sharp, vibrant SDR images are satisfying for a fast IPS panel, but weak contrast and limited HDR stop it from becoming an all-purpose picture-quality leader.

Contrast is acceptable for an edge-lit IPS panel, yet the limited separation between bright and dark elements is conspicuous in cinematic scenes.

Roughly standard IPS contrast leaves dark scenes without true depth. Good SDR color does not make up for the missing OLED-like blacks or local dimming.

Colors are often good to very good after modest adjustments, while factory oversaturation and differing white points prevent universal out-of-box precision.

Factory grayscale and the adjustable sRGB mode perform well, with outstanding accuracy achievable after fine-tuning. Not every measurement or reviewer found it exceptional out of the box.

HDR input is supported, but the display lacks the contrast and local dimming needed for convincing bright highlights against dark scenes.

HDR looks much like bright SDR: it lacks impactful highlights, deep blacks, and the local dimming needed for convincing scene depth.

A quick joystick and responsive menus make changing picture modes, overdrive, and inputs relatively painless.

A responsive joystick and customizable shortcuts make the on-screen settings quick to navigate, despite the large number of controls.

Bright SDR output is a real asset in sunny rooms, although the impressive headline luminance cannot compensate for weak HDR contrast.

The display reaches strong SDR brightness and remains impressively bright with Pulsar on. It also dims enough for many darker spaces.

Variable refresh runs smoothly with both major GPU ecosystems; testers report few flicker or tearing issues.

G-SYNC variable refresh normally combines with Pulsar cleanly across fluctuating game frame rates. Early firmware displayed some doubling issues that were subsequently addressed in testing.

The black stabilizer can lift shadow visibility to make opponents easier to spot, a practical gaming adjustment rather than a cure for poor native contrast.

Shadow Boost lifts darker gray detail and helps reveal objects in dim game environments, though it cannot fix native IPS black depth.

DisplayPort offers a reliable route to high-refresh QHD PC play alongside the two well-equipped HDMI inputs.

DisplayPort 1.4 with DSC provides the full 1440p at 360Hz experience that HDMI cannot deliver on this model.

With no meaningful local-dimming system, bright objects cannot pop against deep blacks the way they can on mini-LED or OLED screens.

There is no useful local dimming for HDR contrast; the segmented Pulsar backlight is designed for motion, not independent dark-scene illumination.

Full-bandwidth HDMI 2.1 inputs are a standout at this price, providing high-refresh compatibility beyond what many rival 1440p monitors offer.

Two HDMI 2.1 inputs add modern console compatibility, but the monitor is limited to 120Hz through HDMI instead of its full 360Hz.

The value rises sharply when discounted into the roughly $300–$400 range. Several testers consider its original $500 positioning hard to justify against newer, less expensive rivals.

The price is steep for an IPS QHD screen, yet dedicated esports buyers can get OLED-rivaling motion without funding a 540Hz-plus GPU-and-monitor setup.

Thin framing helps the understated look, though another tester finds the bezels slightly larger than on some other LG 27-inch displays.

A slim, nearly borderless three-sided front looks clean and keeps attention on the game rather than the frame.

Flicker-free backlight operation is a welcome characteristic for people who notice screen flicker.

Very small low-brightness oscillations are unlikely to trouble most viewers; visible low-frequency ULMB strobing is a separate caveat.

Muted gray styling looks tidy on a desk and avoids aggressive lighting; the industrial rear housing is still distinctly gaming-oriented.

The mostly black, thin-bezel design is understated by gaming-monitor standards. Opinions differ on the illuminated rear ROG styling.

Construction receives positive comments for solid plastics and a stable-feeling build, rather than flashy materials.

The construction feels premium, with a substantial stand and sturdy assembly rather than a flimsy gaming chassis.

Flicker-free backlighting and a low-blue-light setting provide basic comfort controls.

Low-frequency strobing and the warmest blue-light filter can affect comfort or image fidelity. One owner, however, found normal Pulsar gaming fatigue-free.

The 27-inch panel offers a comfortable desktop footprint and room for several windows, without matching the canvas of a larger editing display.

The 27-inch format balances immersion and desk space, with more picture area than many traditional 24- or 25-inch esports monitors.

Gamma is broadly near target in tested modes, with the adjustable sRGB preset helping achieve better tonal accuracy.

Factory gamma does not always match the intended SDR target, but tracking can be refined through unusually precise controls.

An adjustable sRGB mode, unlocked RGB controls, and hardware calibration support are unusually useful for a midrange gaming display.

Precise gamma, RGB, brightness, and color-space controls allow detailed adjustment without the usual sRGB preset restrictions.

Once G-SYNC is configured, enabling Pulsar is largely a single-menu action; it follows changing frame rates without constant retuning.

Fixed-rate ULMB 2 gained 120Hz and 60Hz options through firmware. Narrower pulses can sharpen moving objects further at the expense of brightness and, at 60Hz, comfort.

An IPS LCD avoids the long-term static-image burn-in anxiety associated with OLED, making sustained desktop use less concerning.

The stand includes a pass-through for routing wires, helping keep the setup tidy.

Profile-based calibration delivers excellent measured results, particularly when mapping the native gamut back to sRGB.

Firmware updates can be applied through NVIDIA’s browser workflow and have added useful strobe modes and repaired early VRR issues. The service cable may need to be supplied separately.

Some HDR content benefits from the supported color depth, which can make transitions look smoother than SDR.

Limited highlight headroom can clip bright information and reduce separation in high-contrast scenes.

The 3.5mm output is handy for game audio when the screen itself has no speakers.

Its headphone connection supports DTS Headphone:X and can be useful with compatible headsets; the enhanced spatial experience depends on the headphones.

Accepting a 4K/120Hz console signal and scaling it to QHD is an appreciated compatibility convenience.

A DisplayPort cable is supplied, but one test unit lacked the micro-USB cable needed for firmware updates, adding an unexpected extra step.

The separate power brick is an unwelcome extra at this price and adds clutter compared with an internal supply.

One owner found dead pixels on the initial unit and returned it despite loving the gameplay. That experience does not establish a general defect rate.

Measured power use is low for a bright 240Hz IPS screen, minimizing the monitor's energy penalty.

Sturdy materials and restrained styling make the screen feel better finished than its utilitarian feature set might suggest.

PS5 gaming is responsive at compatible inputs, but the 1440p panel cannot deliver the full native 4K presentation of a 4K-capable PlayStation.

Uniformity is reasonable rather than exceptional, with some edge falloff that may vary from unit to unit.

Near-black gradients are well separated and Shadow Boost can lift dark areas, although raised IPS blacks reduce overall depth.

Conventional RGB subpixels keep fine text clean without the colored fringes that can bother users of some OLED panels.

Missing 4K/24Hz and 4K/50Hz input support can affect smooth movie playback from some external sources.

Pulsar itself does not strobe at 60fps. Updated firmware offers fixed-rate 60Hz ULMB 2 with striking clarity, but visible flicker and higher latency are important tradeoffs.

HDR color and tone presentation need work, even apart from the more fundamental missing local dimming.

There is no DisplayWidget Center support, so settings must generally be changed using the physical OSD controls.

Controls and firmware ran without major trouble in one test, though first-generation Pulsar updates have been important for improving behavior.

The ambient sensor can adjust brightness and color temperature smoothly as room lighting changes, a useful convenience even if some prefer fixed settings.

The built-in 25-inch simulation makes competitive viewing easy to engage and leave, replacing more tedious manual resolution and black-bar setups.

The built-in FPS-labeled counter actually reports the active display refresh rate, which can mislead during frame doubling.

There is no integrated KVM, reducing convenience for people sharing peripherals between computers.

The advertised 1ms pixel response should not be taken literally in normal operation, though most other stated specifications hold up.

Only faint coil whine or fan noise was detected on one tested unit at heavy load, although the sound may vary between samples.

DTS Headphone:X can enhance positional sound and movie immersion when used with compatible headphones.

The standout variable-refresh strobing needs a compatible NVIDIA GPU; AMD users can still get conventional VRR or fixed-rate ULMB 2, but not Pulsar.
