Asus reveals 32-inch 4K OLED with LG RGB-stripe panel

Asus has unveiled the ROG Swift PG32UCWM, a 32-inch 4K gaming monitor that uses a new WOLED panel from LG with an RGB-stripe subpixel layout. The monitor runs at 240 Hz at 4K, offers a 1080p mode at 480 Hz, and carries VESA DisplayHDR True Black 400 certification.

Until recently, OLED gaming monitors relied on various non-standard subpixel structures: LG panels added a white subpixel to boost peak brightness, while Samsung used a triangular layout. The PG32UCWM’s panel returns to a conventional vertical red, green and blue stripe, and the "W" in LG's WOLED refers to the white base emissive material rather than a distinct white subpixel.

That shift has trade-offs. Some 32-inch 4K QD-OLED monitors, including the MSI MPG 322UR X24, already offer brighter True Black 500 certification, and Samsung has announced a 32-inch 4K panel with True Black 600, 360 Hz and RGB-stripe subpixels. The LG WOLED in the Asus tops out at 1,000 nits peak HDR; Asus hasn't quoted a fullscreen figure, though it will likely be in the 250–275 nits range.
