Alienware AW3226Q / ASUS ROG Strix OLED XG27UCDMG

QD-OLED pairs self-emitting pixels with a quantum-dot colour layer; each pixel switches off individually, so blacks are fully dark.

Up to 165 refreshes per second. Dell lists both DisplayPort 1.4 and HDMI 2.1 inputs as reaching 165 Hz at 4K; USB-C does not accept video.

Pixel transition specification, not total input lag.

This is the grey-to-grey pixel transition time, not total input lag.

ASUS notes peak brightness may vary with colour pre-calibration; the peak is reached on a small screen area.

Factory calibration (ΔE < 2) means colours are set close enough to target that differences are hard to see.

Matches the refresh rate to a varying frame rate to reduce tearing.

4K/165 Hz requires a graphics card that supports DSC.

HDMI CEC must be enabled for audio return.

PiP shows a second source in a small window; PbP shows two sources side by side.

Flicker-free refers to brightness dimming; reviewers separately saw VRR flicker in dark scenes.

Terms from the US model page; coverage can differ by country.

Warranty terms may vary by country.

Portrait use is not supported.

The tripod socket lets a camera or light be mounted on the stand.

The 4K 240 Hz signal travels over DisplayPort 1.4 with DSC compression, or over HDMI 2.1 depending on graphics-card support.

The USB-C input takes video from a laptop and charges it at up to 90 W over one cable. HDMI 2.1 suits consoles at 4K 120 Hz.

Variable refresh matches the screen's rate to the graphics card's frame rate, reducing tearing and stutter.

KVM shares a keyboard and mouse connected to the monitor between two computers. The proximity sensor dims the screen when the user leaves to reduce OLED wear.
