Quick verdict
The AW3426DW brings Samsung Display's 5th-generation RGB-stripe QD-OLED to a more accessible price. TFTCentral measured 327 nits SDR (36% more than the older AW3423DW), HDR peaks of 1,300 nits, 0.49 ms response, and 0.86 ms lag, and found text free of the fringing that affected earlier QD-OLEDs. The QuantumBlack film improves perceived contrast in bright rooms.
The savings come from features: DisplayPort 1.4, no USB-C video or charging, no KVM, no blur reduction, no audio output, moderate VRR flicker without an anti-flicker setting, and limited OLED care controls.

Motion, response, and latency
TFTCentral measured 0.49 ms average response and 0.86 ms display lag at 280Hz, with moderate VRR flicker in varying frame rates and no anti-flicker option.
Image quality and HDR
TFTCentral measured 327 nits SDR, 1,300 nits in the Peak 1300 HDR modes, and 537 nits in True Black 500 mode, with an excellent sRGB mode. The RGB-stripe layout gives clean text, and QuantumBlack film makes blacks look deeper in lit rooms than earlier QD-OLEDs.
