HDMI2 × HDMI 2.1

The menu has 2.1(PC) and 2.1(AV) compatibility options. The product page connectivity table omits the HDMI count; the two inputs in the manual were used.

LG		—
USB-C input1 × USB-C; video, data and up to 90 W power

The manual lists DP Alternate Mode and Power Delivery. The port does not power the monitor; the adapter is required.

LG		—
USB hubUSB-C upstream; 2 × downstream USB 3.2 Gen 2

The manual says the downstream ports run at USB 2.0 over a USB-C to USB-C cable and USB 3.0 over a USB-C to USB-A cable.

Panel—31.5-inch OLED, 16:9; 3840 × 2160; 0.1814 mm pixel pitch; matte AGLR surface

About 140 ppi keeps text sharp at 32 inches; the matte surface diffuses reflections but can make blacks look slightly greyer than a glossy finish.

LG
Refresh and Dual Mode—240 Hz at 4K; Dual Mode switches to FHD (1920 × 1080) at 480 Hz via hotkey or joystick

Dual Mode doubles the refresh rate by lowering the resolution; it improves motion clarity in competitive games, while 1080p looks softer on the desktop.

LG
Response time—0.03 ms GtG

GtG is the time a pixel takes to move from one grey shade to another; it is not the same as total input lag.

LG
Brightness and contrast—275 nits typical (250 minimum); 1,500,000:1 typical contrast LG
Colour and HDR—DCI-P3 98.5% (CIE 1976); 1.07 billion colours; HDR10; VESA DisplayHDR True Black 400

The True Black 400 certification sets black level and small-area brightness criteria for OLEDs; full-screen brightness stays below that.

LG
