Compare ASUS ROG Swift OLED PG32UCDM Gen3 vs KOORUI S2721PM

The joystick and desktop control utility make most adjustments straightforward. Hidden physical controls and some complex menu choices can make the first setup less intuitive.

Everyday operation is straightforward with a responsive joystick, but manually switching dimming modes and managing color calibration can feel tedious.

A 90W USB-C connection can carry video and charge a compatible laptop simultaneously, making docking and multi-system use especially convenient.

There is no USB-C charging or power delivery, so it cannot charge a connected laptop.

The passive thermal design remains quiet and cool during testing, with no obvious heat issues from the internal power supply.

The panel can become noticeably warm when local dimming is unexpectedly disabled, raising concern during bright prolonged use.

DisplayPort 2.1, HDMI 2.1, USB-C, USB-A, and audio output create a versatile connection set. The omission of older optical audio output disappoints users of some external DACs.

Video connections cover basic PC and console use, but older HDMI, no USB connections, and few office extras hold back its versatility.

The USB-A connections are useful for peripherals and KVM workflows, but one tester notes that the hub cannot replace every direct PC or console connection.

There is no USB hub, which is inconvenient for keyboards, peripherals, and laptop-based workflows.

Eliminating the external power brick simplifies the desk setup and is repeatedly praised as a practical upgrade, even if the screen itself remains heavy.

The power adapter is external rather than integrated, adding a brick and another cable to manage.

Height, tilt, and swivel feel solid, smooth, and stable, but portrait rotation is missing. The stand also cannot sit as low as some users would prefer.

Height, tilt, swivel, and pivot adjustments are unusually comprehensive for a budget gaming display. Movement is reported as smooth and convenient.

The broad three-legged stand is repeatedly criticized for occupying desk space and obstructing large mousepads. Its sturdy construction helps stability but does not make it convenient on compact desks.

The stand has a space-saving base, though the external power brick adds some clutter to the desk area.

An included 100mm adapter allows a monitor arm to replace the broad tripod stand, a practical solution for limited desk space.

A 100×100mm mount is supported, but one test found standard 10mm screws too short; 12mm M4 screws may be needed.

The Neo Proximity Sensor usually blanks the screen when the user leaves and restores it on return. Sensor timing can still be inconvenient, including reports of unwanted blanking during still moments.

Wake is somewhat slow and may flash odd colors; one reported dimming configuration also failed to reapply after a long sleep.

Variable-refresh flicker can be noticeable in darker scenes or fluctuating frame rates, and one tester found the anti-flicker controls ineffective. Other owners see little flicker or find the mitigation helpful.

VRR flicker is generally minimal and is mainly a risk during unusual very-low-frame-rate swings.

Flexible SDR, sRGB, HDR, and custom modes provide strong calibration and appealing game images. Some dedicated modes restrict adjustments, and a few HDR presets noticeably dim highlights.

HDR Auto is the preferred choice; Movie and Game HDR modes can lift blacks and damage contrast. SDR presets also need careful color selection.

4K at 120Hz, VRR, HDMI 2.1, and HDR support make it a strong match for current consoles. An external audio solution is required because there are no speakers.

The monitor supports PS5 at 1440p/120Hz with VRR in hands-on testing, but HDMI 2.0 prevents 4K/120Hz and limits some Switch 2 HDR combinations. It is more straightforward for PC gaming.

Metal construction, solid adjustments, and premium fit make the monitor feel worthy of its flagship positioning, despite a few plasticky details.

Careful bezel assembly helps it avoid looking cheap, but its all-plastic chassis is not particularly luxurious.

Careful protective packing, reusable sleeve materials, and recyclable molded pulp make unboxing feel appropriately premium.

Simple packaging uses sturdy, dense foam to protect the screen during shipping.

The 4K canvas, readable scaling options, input sharing, and color controls provide genuine work flexibility alongside gaming. Persistent OLED text issues remain a personal dealbreaker for some.

The monitor works well for everyday office tasks thanks to its clear text and adjustable stand, but the lack of USB and KVM functionality limits all-in-one workstation convenience.

BlackShield visibly cuts reflections and purple-tinted blacks compared with older QD-OLEDs, while retaining a crisp glossy image. Direct lighting and WOLED comparisons expose the remaining limitations.

The matte finish reduces visible glare well in daylight, although one detailed hands-on test and an owner found its texture or reflection behavior less refined than ideal.

Instant response and low lag make the monitor fast enough for serious play, with simulated smaller-screen modes available. Some competitive players prefer 27-inch models with 360Hz or higher refresh rates to this larger 240Hz display.

Response times and strobing make fast play credible, but the screen is not the best choice for the most demanding esports competitors seeking 240Hz or higher.

4K detail looks crisp across the generous 32-inch display, benefiting gaming, movies, and office windows. Some users need OS scaling to keep text comfortably sized.

The 2560×1440 panel gives sharp enough text for ordinary desktop work and a good gaming-detail balance on 27 inches. A 4K alternative remains noticeably sharper for text.

Colors and contrast remain striking from different seating positions, with testers finding little visible shifting when viewing off-axis.

Side views stay comparatively consistent, useful when other people watch or play nearby. A heavy anti-glare coating may still affect some viewing angles.

QD-OLED's individual pixel control makes it especially capable for vivid HDR gaming, with excellent contrast and quick pixel response.

The fast IPS panel offers steady off-axis color and good motion response, with weaker native blacks than VA rivals.

The QD-OLED panel delivers exceptionally deep blacks in dark environments, and BlackShield reduces the old purple cast under room lighting. Bright light can still make blacks appear gray compared with the best WOLED alternatives.

Mini LED dimming can make night scenes noticeably darker than ordinary IPS, but deep blacks and small highlight control still lag stronger VA screens.

There are no integrated speakers, a repeated frustration given the premium price. Console and casual media users need a headset, soundbar, or external speakers.

There are no built-in speakers, so external audio is necessary.

Rapid OLED transitions produce exceptionally clean moving objects and little visible overshoot, even in demanding motion tests.

Moving objects show relatively little trailing, and the strobing mode produces minimal double images when configured well.

Several testers see excellent consistency and clean panels, particularly in controlled modes. One lab finds noticeable edge dimming outside the uniform-brightness and sRGB presets.

Brightness variation across the panel is very low in detailed testing, and the corners show little distracting falloff.

OLED pixels change almost instantly, producing precise movement and clean transitions with little blur across multiple refresh rates.

Response is good for an IPS gaming display and competes well with similarly priced monitors. Tuning matters because the most aggressive overdrive setting overshoots.

At 240Hz, fast motion is extremely clean and sharp, with rapid transitions and very little blur. Enthusiasts seeking the absolute highest esports clarity may still prefer faster 360–540Hz displays.

Fast IPS response and effective strobing keep motion relatively clean, making gameplay smoother than slower alternatives. The DIC mode is especially effective at reducing blur.

The 4K image generally looks very crisp, and many reviewers find text sharp enough for work. A few owners report unusually soft text, fringing, and discomfort that settings did not resolve.

Text generally looks crisp from a normal desk distance and is comfortable for office tasks. Higher-resolution 4K models still show finer detail.

High-refresh 4K gameplay is outstanding with a capable graphics card, and newer inputs support modern hardware. Reaching the full 240fps at 4K remains demanding.

DisplayPort unlocks QHD at 200Hz, while fast response and HDR produce a strong PC gaming experience once settings are tuned.

The 240Hz ceiling is an excellent balance for 4K gaming and remains much smoother than 60–120Hz displays. Some high-level esports players want 360Hz or faster instead.

The 200Hz headline is a meaningful upgrade over 60Hz and slightly faster than some close competitors. Some owners drop to 144Hz to avoid visible scanline artifacts in certain modes.

The monitor supports smooth G-Sync and FreeSync operation at high refresh rates. Some firmware-specific anti-flicker options did not work as intended in one test.

Adaptive refresh works over DisplayPort and HDMI, including PS5 VRR in direct testing. Other sources caution against assuming every console output mode is supported.

Wide QD-OLED color coverage creates richly saturated game worlds and HDR highlights. It also supplies flexible color-space options for work where faithful colors matter.

Quantum-dot color coverage is unusually wide for the price, extending through DCI-P3 and Adobe RGB. Wide gamut is not a substitute for accurate calibration.

Near-instant inputs make games feel remarkably responsive at 240Hz; lower fixed refresh rates are still fast. ELMB can introduce an additional delay when used.

Input response is extremely quick at gaming refresh rates, with no appreciable delay expected for most players.

Most reviewers consider this one of the most polished 32-inch 4K OLED gaming monitors available. Price and minor ergonomic issues temper that enthusiasm, while a small number of owners describe serious discomfort or reading problems.

The display earns strong marks for its surprising performance at a budget price, especially once HDR and color are configured. Buyers nevertheless report software quirks that can undermine an otherwise impressive panel.

The stand provides an effective internal cable route, and its cable tidy opening helps control the clutter from multiple connected devices.

A cable pass-through in the stand helps keep basic video and power leads tidy.

Large, detailed worlds look magnificent thanks to rich QD-OLED colors, deep blacks, HDR highlights, and the immersive 32-inch canvas. This is where the monitor attracts its strongest recommendations.

RPGs and visually detailed solo games benefit enormously from luminous highlights, wide color, and strong HDR contrast.

The integrated KVM can switch mouse and keyboard control between connected systems without a separate box. One dual-computer user reports smooth automatic handoff and no peripheral lag.

The missing KVM switch prevents easy keyboard-and-mouse sharing between computers.

Accurate factory settings and strong calibrated results make SDR and HDR colors look convincing without extensive adjustments. Certain presets can be locked down or overly saturated, so the right color mode matters.

Factory settings and several color modes can look too cool, warm, or saturated depending on configuration. Manual calibration improves results, but critical color work needs care.

Per-pixel OLED illumination creates powerful dark-scene contrast and bright objects without distracting halos. It is a major advantage over many backlit LCD displays.

The 1,152-zone system strengthens HDR depth at a remarkably low price, yet halos, small-object dimming, and occasional mode-reset behavior leave it short of premium implementations.

Per-pixel OLED dimming gives bright highlights striking separation from deep dark scenes with essentially no blooming. Contrast is most impressive when ambient light is controlled.

Mini LED dimming significantly improves apparent HDR contrast over ordinary IPS screens, but native IPS contrast is modest and VA competitors render darker blacks.

The tougher BlackShield surface is easier and less stressful to wipe down than older glossy OLED coatings. Testers particularly welcome fewer visible cleaning marks and scratches.

Tight-fitting bezel seams leave fewer dust-catching gaps than some competing designs.

Most testers like the fast joystick menus and customizable shortcuts, with desktop software as another option. One found important VRR and HDR controls hard to locate.

The joystick-driven OSD is fast and intuitively organized, though options are limited and some owners dislike how changing modes affects their image.

Full-bandwidth DisplayPort 2.1 enables 4K 240Hz without DSC on compatible hardware. While technologically current, a few testers say the visible improvement over older DSC connections is minimal.

DisplayPort 1.4 is the connection to use for the full 200Hz PC experience. HDMI is limited to a lower refresh rate.

The uniform-brightness setting can keep desktop luminance steady, while more dramatic HDR modes may noticeably dim across changing scenes. Experiences vary with the chosen mode and content.

The display can gently reduce brightness on extended bright screens, which one owner finds easier on the eyes.

Picture-in-picture and side-by-side input modes make it easier to monitor two connected devices, a welcome addition to an already flexible gaming display.

PIP and PBP are described as useful for displaying more than one input, although other reviewers focus on limited USB-based productivity features.

SDR and larger-area HDR brightness have improved over earlier versions, helping colorful games and desktop apps. Several tests still find small-highlight gains modest and OLED television HDR considerably brighter.

Both SDR and HDR are notably bright, with vivid highlights that can dominate a scene. The minimum brightness may be too high for sensitive night-time users, and some owners find bright white transitions uncomfortable.

FreeSync and G-Sync support help keep gameplay fluid, though testing of the anti-flicker options uncovered a separate VRR-related weakness.

Variable refresh is supported over both major video connections and helps avoid tearing across a broad gaming frame-rate range.

The sharp 4K image, highly saturated colors, and striking OLED contrast draw overwhelming praise. Bright-room black levels and text rendering keep it from being universally flawless.

The panel can produce excellent HDR color, brightness, and contrast for the money. SDR out of the box looks less polished and may require work.

Rich color, nearly perfect blacks, and bright highlights make HDR gaming a standout experience. Actual brightness gains over previous QD-OLED generations are more modest than the marketing suggests, and dimming varies by HDR mode.

Bright highlights and localized backlighting make HDR the clear highlight of this monitor, provided the Auto HDR mode is used. Haloing and inaccurate alternative presets remain compromises.

Shadow Boost can help reveal some darker game details, but changes affect midtones more than the darkest shades and can make parts of the picture unnaturally bright.

Shadow enhancement offers some useful adjustment, but stronger settings wash out the screen instead of selectively brightening dark areas.

Full HDMI 2.1 support is welcomed for fast console connections, including modern 4K and VRR features.

HDMI 2.0 is the major connection compromise: it cannot drive the panel at its 200Hz maximum or provide 4K/120Hz console output. A separate hands-on test did confirm PS5 VRR at supported lower resolutions.

Flagship image quality and build are widely praised, but the high asking price faces strong competition from cheaper OLEDs. Owners of the original PG32UCDM gain relatively little unless the coating improvements matter to them.

Mini LED HDR, a fast QHD screen, and wide color coverage deliver unusually strong value at discounted prices. The appeal is less clear when pricing rises toward more fully equipped rivals.

Three-year coverage including OLED burn-in is valued as added reassurance with an expensive self-emissive display; it cannot eliminate all ownership risks.

Warranty terms may vary by region and are not entirely consistent between printed claims and retailer pages; buyers should confirm local coverage.

Most testers find the stand straightforward to assemble and the connections manageable. One reviewer dislikes the extra projector parts required during initial setup.

Mechanical assembly is straightforward and requires no screwdriver. Display color calibration, however, can be considerably more complicated.

An owner reports repeated Mac crashes with this monitor at 4K 240Hz, a concerning configuration-specific problem that could undermine dependable daily use.

An owner in the discussion reported losing half the backlight within a week, while others have had satisfactory use. Long-term dependability remains uncertain.

One owner experienced persistent eye strain and headaches despite using blue-light filtering, so the controls could not solve their discomfort.

Flicker-free backlighting is a useful advantage for sensitive viewers, though minimum screen brightness can be uncomfortable in a dark room.

The chassis and metal stand feel impressively rigid and substantial, with very little wobble. A minor complaint is that some plastic detailing feels less expensive than the rest of the build.

The body uses budget plastic but fits together neatly, and owner feedback on construction is generally positive.

The thin front bezel looks clean and modern, but the heavily branded RGB accents and conspicuous tripod stand divide opinion. Much of the lighting can be switched off.

The understated, narrow-bezel design looks cleaner than a typical inexpensive gaming monitor, without flashy lighting.

The 32-inch display adds immersion and workspace compared with 27-inch monitors. Its size can feel excessive to players who sit close and focus on competitive shooters.

The 27-inch screen is seen as a useful sweet spot for detailed QHD games and ordinary desk work.

DisplayWidget Center offers useful desktop control and firmware updates, making the monitor simpler to manage from a computer. Firmware-related concerns remain around anti-flicker behavior.

Generic display drivers work, but absent dedicated tools complicate calibration, settings recovery, and troubleshooting.

DisplayWidget Center simplifies settings, profiles, and firmware maintenance without reaching for the joystick. Most testers find the menus flexible, though the utility adds another app to install.

There is no official Windows OSD control software, leaving owners to use hardware controls or third-party alternatives.

The supplied VESA adapter gives owners the option to use a monitor arm, addressing the broad stand's desk-space drawback. Included cables and mounting accessories also support flexible setups.

Smaller simulated 27-inch and 24.5-inch modes give players a more focused gaming area without replacing the screen. They are particularly appealing for shooters on a large 32-inch panel.

Individual tested units show little noticeable corner glow or bleed, though the appearance changes when local dimming is off.

Halos can form around subtitles, cursors, and bright objects on black backgrounds. Some viewers find them mild, but they are more obvious in dark scenes.

A proximity sensor, pixel refresh, screen shifting, and static-logo protections add meaningful reassurance. One tester found the sensor could occasionally blank the screen during play if its timer was too aggressive.

The main owner received a panel without visible dead pixels or backlight bleed, although other units in the discussion showed defects.

PCs and laptops connect through versatile modern inputs, though a Mac mini owner reports occasional crashes. Apple scaling and refresh behavior may need extra attention.

A printed sRGB calibration report is supplied, but one tester found that its claim did not match perceptually accurate color.

Very narrow bezel gaps are less likely to collect dust than the wider seams on some competing displays.

KOORUI’s DIC black-frame insertion produces excellent motion clarity with surprisingly usable brightness. It does require disabling VRR and local dimming.

No firmware version is exposed and there is no practical user firmware-update path, making future bug fixes uncertain.

The cable bundle is unusually generous, including a practical full-bandwidth DisplayPort lead and useful mounting accessories.

ELMB can recreate 240Hz-like clarity at a fixed 120Hz, which helps lower-powered systems. It also cuts brightness, disables VRR and HDR, and can add enough lag to limit its appeal.

The Fast setting brings response times under control without excessive artifacts; the very fastest setting introduces significant overshoot.

Color and brightness preferences are not stored separately for each source, meaning laptop and desktop users may have to reset their settings after changing inputs.

The substantial screen and built-in power supply make this a heavy monitor to unpack and move, even if that heft accompanies sturdy construction.

Stock differs sharply by region: some sellers have had ample inventory or discounts, while other buyers report no local listings or sell-outs.

Fine horizontal line patterns can appear on saturated static colors, especially near 180Hz. Owners report improvement at 144Hz and sometimes 200Hz, but the defect can be a deal-breaker.

The coating controls reflections, but its relatively aggressive texture can be noticeable up close and may affect off-angle clarity.

Switching between HDR and SDR can trigger brightness, color, and local dimming quirks that sometimes need resetting.

The stand secures firmly during assembly and is a practical base for everyday use.

The proximity sensor conveniently switches pixels off when the desk is unattended and restores the screen upon return. Its delay options and occasional unwanted blanking can be frustrating.

Most testers find the 4K pixel density makes QD-OLED edge color artifacts hard to notice. Some sensitive owners see softer text or distracting fringing, especially when reading light text against dark backgrounds.

Manual RGB and color-mode adjustments can substantially improve grayscale accuracy, but configuring SDR and HDR separately can take patience.

KOORUI’s own specifications conflict about USB, display brightness terminology, and warranty duration; buyers should verify seller terms.

Passive cooling kept the monitor effectively silent over several days of use, with no fan noise to distract from games.

BlackShield's tougher surface makes cleaning feel less risky, and some testers report clear improvements in resistance to marks. Longer-term scratch resistance is not yet established.
