| Panel | 31.5-inch flat QD-OLED; 3840 × 2160; 0.1814 mm pixel pitch; anti-reflection surface QD-OLED converts blue OLED light to red and green with quantum dots; because each pixel makes its own light, blacks can switch fully off. 4K at 32 inches gives roughly 140 ppi. MSI | 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 and response | 240 Hz (48–240 Hz variable range); 0.03 ms GtG MSI says 240 Hz at 4K is reachable over DisplayPort 1.4a, HDMI 2.1 and USB-C alike. 0.03 ms is grey-to-grey transition time, not total input lag. MSI | — |

| Brightness and HDR | 250 nits typical; DisplayHDR True Black 400; 1,500,000:1 typical contrast DisplayHDR True Black 400 is the VESA class for displays that can produce deep blacks such as OLED; it requires 400-nit small-area brightness and a very low black level. 250 nits is the full-screen SDR figure.

| Colour | 10-bit (1.07 billion colours); 99% DCI-P3, 97% Adobe RGB, 138% sRGB 138% sRGB means the gamut extends well beyond sRGB; use the monitor’s sRGB mode so sRGB content does not look oversaturated. MSI | 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.

| Adaptive sync | G-SYNC Compatible; AMD FreeSync Premium Pro Adaptive sync matches the display refresh to the game’s frame rate to reduce tearing and stutter. FreeSync Premium Pro adds a low-latency requirement in HDR. MSI | — |
|---|
| Inputs | 1 × DisplayPort 1.4a; 2 × HDMI 2.1; 1 × USB-C (DP Alt Mode, 90 W PD); 2 × USB 2.0 Type-A, 1 × USB 2.0 Type-B; headphone out The USB-C input can carry video and charge a laptop at up to 90 W over a single cable. Display Ninja says the monitor has a built-in KVM; the USB-A ports run at USB 2.0 speed. MSI | — |

| Warranty | 3 years, including panel burn-in On OLED panels, images left static for long periods can leave a permanent mark (burn-in); MSI covers this risk under warranty. Terms may vary by country. MSI | — |

| 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 |
|---|
| Brightness and contrast | — | 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 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 |
