Panel31.5-inch flat VA (vertical alignment) panel, LED edge backlight; 16:9, 3840 × 2160 (4K UHD), 139 ppi; anti-glare 3H-hardness surface

Dell lists 3000:1 contrast and 178°/178° viewing angles for this VA panel; the viewing-angle figure does not show at what angle colour and contrast start to shift.

Dell		44.5-inch WOLED, 21:9, 800R curve; 5120 × 2160 (5K2K), 0.2035 mm pixel pitch (about 125 ppi); MLA+

800R means the screen curves along a circle with an 80 cm radius, so the edges sit closer to the eyes. MLA+ (micro lens array) directs OLED pixel light forward to raise brightness.

LG
Refresh rate and response time120 Hz (48–120 Hz vertical frequency); 4 ms GtG (Extreme), 5 ms GtG (Fast), 8 ms GtG (Normal); AMD FreeSync Premium

120 Hz at 4K is available over both HDMI 2.1 and DisplayPort 1.4; the source must also output 4K at 120 Hz. FreeSync Premium matches the refresh to the game’s frame rate within 48–120 Hz to prevent tearing; AMD’s tier also includes low framerate compensation (LFC). GtG figures are given for the fastest overdrive mode.

Dell		—
Brightness, contrast and colour300 nits; 3000:1 contrast; 1.07 billion colours; 95% DCI-P3, 99% sRGB; HDR10

HDR10 support means the monitor accepts HDR signals; with 300 nits and edge lighting it carries no DisplayHDR tier. 1.07 billion colours corresponds to 10-bit colour depth.

Dell		—
Connections2 × HDMI 2.1 (FRL, HDR, VRR; up to 4K 120 Hz; HDCP 2.2), 1 × DisplayPort 1.4 (4K 120 Hz, HDR, VRR; HDCP 2.2)

There is no USB-C, USB hub, headphone output or webcam, so a laptop cannot be charged over a single cable. A 1.8 m HDMI cable is in the box.

ComfortView Plus cuts blue light to 35% or less at the hardware level; Dell says this does not affect colour accuracy.

Refresh rate and response—165 Hz at 5K2K; 330 Hz at WFHD with VESA-certified Dual-Mode; 0.03 ms (GtG)

Dual-Mode doubles the refresh rate by lowering the resolution: 330 Hz for fast competitive games, 5K2K at 165 Hz for detailed games.

LG
Brightness and HDR—275 cd/m² typical (minimum 250); HDR10, VESA DisplayHDR True Black 400; DCI-P3 98.5%; 10-bit; contrast 1,500,000:1 (typical)

DisplayHDR True Black 400 is VESA’s certification for screens that can turn black fully off, such as OLED, and requires 400 nits peak brightness.

LG
Sync—NVIDIA G-SYNC Compatible, AMD FreeSync Premium Pro, VRR

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

LG
Inputs—2 × HDMI, 1 × DisplayPort 2.1 (DSC), 1 × USB-C (5120 × 2160 at 165 Hz, data, 90 W power); 2 × USB 3.0 downstream; 4-pole headphone/mic

DSC compresses the image visually losslessly so high resolution and refresh rate fit through one cable. USB-C gives a laptop video, data and 90 W charging over one cable. LG notes NVIDIA released a driver in April 2025 that fixed screen blackouts seen over DisplayPort.

LG
PiP and PbP—PIP and 2-source PBP

PiP shows one source in a small window, and PbP splits the screen to show two sources side by side, for example a computer and a game console at once.
