| Panel | 26.5-inch QD-OLED, 16:9; 3840 × 2160 (4K); 0.153 mm pixel pitch The small pixel pitch (about 166 ppi) makes text and interface edges look sharper than on 27-inch 1440p monitors. ASUS | 44.5-inch (113 cm) OLED, 800R curve; 3440 × 1440 (21:9); 0.303 mm pixel pitch 800R means the screen curves like part of a circle with an 800 mm radius, wrapping the edges around your view. At 45 inches, 1440p gives low pixel density: up close, text and fine detail look less sharp than on a 27-inch 1440p screen. LG |

| Refresh rate and VRR | 240 Hz; 48–240 Hz variable refresh on HDMI and DP/USB-C inputs; FreeSync Premium Pro, G-SYNC Compatible, VESA AdaptiveSync Display 240Hz All inputs support 240 Hz at 4K; variable refresh prevents tearing and stutter as the game frame rate moves between 48 and 240. ASUS | — |
|---|
| Response time | 0.03 ms (GtG) Grey-to-grey transition time; because OLED pixels change much faster than LCD, motion blur depends mostly on the refresh rate. ASUS | — |
|---|
| Brightness and contrast | 1,000 cd/m² HDR peak; 1,500,000:1 typical contrast 1,000 cd/m² is a peak reached on a small area of the screen; a full white screen stays much lower. ASUS gives no typical SDR brightness value. ASUS | 200 cd/m² typical (160 minimum); typical contrast 1,500,000:1 LG’s typical brightness refers to a full-screen SDR image; with self-emissive OLED pixels black switches fully off, giving very high contrast. LG |
|---|
| HDR | VESA DisplayHDR 400 True Black; HDR10; Dolby Vision The True Black tier measures OLED’s very low black level; 400 is the minimum peak brightness threshold in the certification test. Dolby Vision support lets compatible sources use scene-by-scene HDR data. ASUS | — |
|---|
| Colour | 99% DCI-P3, 145% sRGB; 10-bit (1.07 billion colours); ΔE < 2 ΔE < 2 means factory calibration deviates from target colours by an amount most people cannot see; a calibration report is included. ASUS | DCI-P3 98.5% (typical, CIE1976), 90% minimum; 1.07 billion colours; factory calibrated; hardware calibration ready Hardware calibration writes settings into the monitor itself through LG Calibration Studio, so the colour setup stays with the monitor even if the computer changes. LG |
|---|
| Inputs | 1 × DisplayPort 2.1; 2 × HDMI 2.1 (FRL); 1 × USB-C (DP Alt Mode, 90 W power delivery); headphone jack USB-C takes video over a single cable and supplies up to 90 W to a laptop. The HDMI 2.1 inputs can be used for 4K 120 Hz on consoles. ASUS | — |
|---|
| USB and KVM | 3 × USB-A 5 Gbps (USB 3.2 Gen 1) hub; KVM switch KVM moves the keyboard and mouse attached to the monitor between two computers when the input is switched. ASUS | — |
|---|
| Speakers | None A headphone jack or external speakers are needed for audio. ASUS | — |
|---|
| OLED protection | ASUS OLED Care; Neo Proximity Sensor OLED Care includes burn-in prevention functions such as pixel cleaning, screen shift, logo brightness adjustment and taskbar detection. The proximity sensor dims the screen when the user leaves, reducing static image time. ASUS | — |
|---|
| Power consumption | Under 80 W in operation; under 0.5 W in standby, 0.3 W off ASUS | — |
|---|
| Stand and mounting | Tilt +20°/−5°, swivel ±30°, pivot ±90°, height 0–110 mm; VESA 100 × 100; 1/4-inch tripod socket The tripod socket is used to mount accessories such as a camera or light on the stand. ASUS | Tilt, height and swivel adjustment; 100 × 100 mm VESA wall mount LG |
|---|
| Dimensions and weight | With stand 61.03 × 54.95 × 21.88 cm, 7.62 kg; without stand 61.03 × 36.92 × 7.05 cm, 4.97 kg ASUS | — |

| Warranty | 3 years, including panel burn-in Warranty terms can vary by country. ASUS | — |

| Refresh rate and response time | — | 240 Hz; 0.03 ms (GtG) 240 Hz shows very smooth motion when a game approaches 240 frames per second, which needs a powerful graphics card. 0.03 ms grey-to-grey describes the fast transition of OLED pixels; it is not total input lag. LG |
|---|
| HDR and sync | — | HDR10, HDR effect; NVIDIA G-SYNC Compatible, AMD FreeSync Premium, VRR G-SYNC Compatible and FreeSync Premium match the refresh rate to the graphics card’s frame rate to reduce tearing and stutter. HDR effect is a picture mode that adds HDR-like contrast to SDR content in software; it is not real HDR. LG |
|---|
| Gaming features | — | Black Stabilizer, Dynamic Action Sync, crosshair, FPS counter, user-defined key, auto input switch Black Stabilizer brightens detail in dark scenes; Dynamic Action Sync is a mode that reduces input lag. LG |
|---|
| PiP | — | Picture-in-picture (PiP) PiP shows a second input in a small window over the main picture, for example a PC and a console at the same time. LG does not list PbP (side-by-side split) for this model. LG |
|---|
| Connections | — | 2 × HDMI, 1 × DisplayPort 1.4 (DSC), 1 × USB 3.0 upstream, 2 × USB 3.0 downstream, optical digital audio out (S/PDIF), 4-pole headphone out (sound + mic) DSC (Display Stream Compression) compresses high-bandwidth signals such as 3440 × 1440 at 240 Hz over DisplayPort 1.4 without visible loss. With the USB upstream connected, the monitor’s USB-A ports act as a hub for the computer. A headset with a mic plugs into the 4-pole jack; DTS Headphone:X adds virtual surround. No built-in speakers are listed. LG |
|---|
| Lighting and control | — | Hexagon RGB lighting on the back; remote control; OnScreen Control and Dual Controller software LG |
|---|
| Power | — | External adapter; 100–240 V; 129 W typical, 160 W max, under 0.5 W in sleep LG |
