Panel49-inch QD-OLED; 5120 × 1440 (DQHD), 32:9; 1800R curve

The 32:9 ratio gives a workspace equivalent to two 27-inch 1440p monitors side by side. The 1800R curve keeps the edges closer to the eyes.

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 response144 Hz (adaptive range 48–144 Hz); 0.03 ms (GtG)

Adaptive sync prevents tearing while the frame rate stays between 48 and 144. Reaching 144 fps at full resolution needs a very powerful graphics card.

Brightness and contrastTypical SDR 250 nits; 1,500,000:1; DisplayHDR True Black 400

True Black 400 is the OLED-class certification for very low black level and 400-nit HDR brightness.

MSI		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
Colour99% DCI-P3, 146% sRGB, 98% Adobe RGB; 10-bit (1.07 billion colours) MSIDCI-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
Adaptive syncAMD FreeSync Premium Pro

The Premium Pro tier includes low frame rate compensation and low-latency tone mapping in HDR.

Connections1 × 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

USB-C takes video from a laptop over one cable and charges it at up to 90 W. The USB ports run at USB 2.0 speed; there are no built-in speakers.

MSI		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
Multi-viewPiP / PbP

PbP splits the 49-inch screen side by side between two sources to show two computers at once; PiP shows one source in a small window over the other.

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.
