Scorata scores summarize analyzed review evidence on a 1–5 scale; they are not laboratory measurements or a simple average of customer star ratings. Feature scores summarize the reviews covering that feature. The overall score averages feature scores within each review, then combines review averages. When both expert and customer evidence are available, those two groups receive equal weight. Products can have different review coverage, so small score gaps do not establish a winner.
Recommendations prioritize important features for the category, with a score of at least 3.5, a gap of at least 0.25 points and at least two supporting reviews per product. Features with widely varying scores or broad connectivity contexts are excluded from recommendations. These safeguards do not establish statistical significance.
Quick verdict
The review evidence points to a tradeoff: ease of use and value for money versus KVM switch performance and USB-C power delivery. Choose according to which strengths matter more to you; the overall score alone does not settle that choice.
Choose ASUS ROG Strix XG27ACS for ease of use and value for money.
Choose ASUS ROG Swift OLED PG27UCDM for KVM switch performance and USB-C power delivery.
Scores are out of 5. Missing scores mean missing review evidence, not a missing feature.

The control joystick and logical menus make frequent adjustments quick and intuitive instead of cumbersome.
SDR material looks unusually accurate even with HDR mode active, minimizing the need to swap Windows display modes.
Switching into Dolby Vision triggered repeated display blackouts when opening different programs, prompting a move back to standard HDR.
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.
The 90W USB-C connection can carry a laptop's picture, data, and power together. Higher-demand laptops may still need their own charger.
There are no downstream USB-A ports, making the monitor disappointing as a peripheral hub or simplified docking station.
The built-in USB hub keeps keyboards and mice connected to the display and cuts down on cable runs to a desktop PC.
Dark scenes look noticeably gray rather than inky black. The limitations are particularly apparent beside VA, mini-LED, and OLED displays.
Dark-room blacks look almost perfectly inky with no gray backlight haze. Direct lighting can make the QD-OLED panel appear grayish or purplish instead.
The self-contained power supply avoids an external brick, but the sealed design is a drawback if power components ever need service.
The integrated power supply eliminates a separate external brick, simplifying cabling and desk placement.
ELMB can introduce visible red fringing around moving elements even at high refresh rates.
At this pixel density, the colored fringes associated with older QD-OLED monitors become very hard to notice. A few users may still spot artifacts in certain text or window edges.
The matte coating contains moderate grain, a small clarity tradeoff for its anti-reflection properties.
The semi-gloss finish preserves a notably clear and vivid image without the grain of some matte coatings. Bright reflections remain an unavoidable compromise.
DisplayPort, HDMI, and USB-C video provide useful flexibility, but a single HDMI on some configurations and missing USB-A hub limit elaborate setups.

A high-end PC can make excellent use of the 4K/240Hz panel's sharpness and low latency. More modest graphics hardware will not always reach the top refresh rate.
Fast pixel transitions, low latency, and 180Hz refresh suit quick multiplayer games particularly well. Extreme esports players may still want higher refresh rates.
The 240Hz OLED speed, minimal input lag, and compact view make fast shooters highly responsive. It remains a demanding choice for PCs trying to push 4K frames.
There is no local dimming hardware, so HDR cannot isolate bright highlights from dark backgrounds.
Per-pixel dimming allows fine control of bright objects against black backgrounds, avoiding the zone-by-zone compromises of typical LCDs.
A missing USB hub means it cannot serve as a KVM for sharing keyboard and mouse peripherals between computers.
An integrated KVM lets a keyboard and mouse move between a desktop and laptop without constant cable swapping. It's one of the more practical extras.
IPS contrast leaves shadowy scenes looking gray and washed out. Brighter colorful games flatter this panel much more than dark cinematic material.
Pixel-level light control produces outstanding scene depth and contrast, especially in darker rooms. Strong ambient light can diminish that striking effect.
HDR400 can add a little color and brightness excitement, but poor blacks and no local dimming prevent convincing HDR highlights.
Rich blacks and intense small highlights give HDR games and movies real impact. Large bright scenes and the compromises between HDR modes keep it short of a flawless presentation.
Shadow Boost makes dark details easier to see, though pushing those shadows can spoil the atmosphere of some games.
Shadow Boost makes opponents hiding in dark areas easier to spot without demanding a separate software workaround.
DisplayPort and USB-C DisplayPort Alt Mode make the fastest refresh settings accessible from compatible PCs and laptops.
Full 80Gbps DisplayPort 2.1 can deliver uncompressed 4K at 240Hz with compatible hardware, bypassing DSC-related limitations. The visible difference from working DSC is usually small.
SDR brightness is punchy enough for ordinary indoor gaming and many brighter rooms. Turning on ELMB cuts that headroom substantially.
