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

There is no integrated KVM, a drawback for anyone switching one set of peripherals between two computers.

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

The absence of PiP/PbP rules out viewing two external sources together in split or overlaid windows.

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.

The new panel delivers a meaningful improvement in SDR brightness and striking HDR peaks. Performance depends on window size and brightness settings.

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

G-SYNC and FreeSync work well for variable-frame-rate gaming, though using stronger anti-flicker modes can narrow the effective VRR range.

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.

Peak SDR output can dip noticeably as more of the display becomes bright. Uniform Brightness removes those fluctuations at the cost of the brightest small-window output.

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.

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

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

The 3.5mm connection provides an uncomplicated way to get sound despite the absence of built-in speakers.

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.

Its nearly identical naming to other ASUS OLED models draws criticism and makes model identification unnecessarily difficult.

Black-frame insertion offers sharper 120–140Hz motion but disables some valuable gaming features and has limited activation flexibility.

The supplied packing materials protect the stand and panel adequately while keeping unpacking fairly straightforward.

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

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

Measured power use is improved over older WOLED panels, particularly for bright white content; gaming gains are more modest.

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

The Neo Proximity Sensor is repeatedly praised for blanking the OLED after someone leaves and restoring the image on return.

Early launch timing and limited regional retail availability created frustration despite the favorable OLED price.

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

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

The recessed downward-facing ports can be awkward to reach without rotating the screen.

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

Uniform Brightness keeps the screen steady as window sizes and content change. The consistency comes with a limit on peak brightness.

Colors appear more vivid than on older WOLED models, although pure-color brightness still trails top QD-OLED alternatives.

DisplayPort 1.4 with DSC runs the native QHD/280Hz combination capably, even though the connection is not the newest DP 2.1 standard.

Some reported peak-brightness values sent to Windows do not match measured capabilities, complicating automatic calibration.

ASUS cites a longer-life panel and supplies care features, but the actual lifetime improvement has not been independently established.

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

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

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