Specification	MSI MPG 341CQPX QD-OLED	LG UltraGear 27GP750-B
Release year	2024	2021
Panel	34.18-inch curved QD-OLED, 1800R; 3440 × 1440 (UWQHD), 21:9; 0.2315 mm pixel pitch 1800R is the curve of a circle with a 1.8 m radius; it brings the edges of the wide screen closer to your eyes. The 21:9 ratio gives a wider field of view in supported games and room for two windows side by side. MSI	27-inch (68.5 cm) IPS; 1920 × 1080; 16:9; pixel pitch 0.3108 mm A 0.31 mm pixel pitch works out to about 82 ppi at 27 inches. Viewing angles are 178°/178°. LG
Refresh and response	240 Hz (48–240 Hz variable range); 0.03 ms GtG 240 Hz is reached at full resolution over DisplayPort 1.4a or HDMI 2.1. 0.03 ms is pixel transition time, not total input lag. Below 48 fps the frame rate falls outside the variable refresh range. MSI	Up to 240 Hz; 1 ms (GtG, in Faster mode) LG quotes 1 ms for grey-to-grey transitions at the fastest overdrive setting. Dynamic Action Sync aims to reduce input lag, and Black Stabilizer brings out detail in dark scenes. LG
Brightness and HDR	250 nits typical SDR; 1,000 nits peak HDR at 3% APL, 450 nits at 10% APL; VESA DisplayHDR True Black 400; 1,500,000:1 contrast 1,000 nits is reached only on bright areas covering about 3% of the screen (explosions, sun glints); as the bright area grows, OLED automatic brightness limiting kicks in. MSI	—
Colour	10-bit (1.07 billion colours); DCI-P3 99.3%, Adobe RGB 97.8%, sRGB 139.1% (CIE 1976) sRGB above 100% means sRGB content can look oversaturated unless shown in a clamped mode. MSI	—
Variable refresh	G-SYNC Compatible, AMD FreeSync Premium Pro Matching refresh to the graphics card’s frame rate reduces tearing and stutter; FreeSync Premium Pro also covers low-latency HDR operation. MSI	NVIDIA G-SYNC Compatible; AMD FreeSync Premium Variable refresh matches the monitor’s refresh rate to the graphics card’s frame rate to reduce tearing and stutter. LG
Video inputs	1 × DisplayPort 1.4a (3440 × 1440 240 Hz); 2 × HDMI 2.1 (UWQHD 240 Hz); 1 × USB-C (DisplayPort Alt Mode, 98 W Power Delivery) USB-C takes video from a laptop over one cable and charges it at up to 98 W; the PD charging option must be enabled in the OSD. The USB-C data path runs at USB 2.0 speed. MSI	—
USB and audio	2 × USB 2.0 Type-A, 1 × USB 2.0 Type-B (upstream); headphone out; no built-in speakers The USB-A ports are for low-speed devices like keyboard and mouse; they are not suited to external SSDs. MSI	—
KVM and multi-view	Built-in KVM; PiP (picture-in-picture) and PbP (picture-by-picture) KVM shares the keyboard and mouse attached to the monitor between two computers; switching is done via the USB option in the OSD. PbP splits the screen between two sources, PiP shows one in a small window. MSI	—
Surface and viewing angle	Anti-reflection surface treatment; 178° / 178° MSI	—
Stand and mounting	Tilt −5° / 20°, swivel −30° / 30°, height 0–100 mm; VESA 100 × 100 MSI	Height, tilt and pivot adjustment; VESA 100 × 100 Height adjustment changes the overall height with the stand between 465.9 and 575.9 mm. LG
Size and weight	With stand 812 × 318 × 427 mm, 8.8 kg; without stand 812 × 130 × 361 mm, 6.66 kg MSI	Without stand 614.2 × 364.8 × 51.7 mm, 3.9 kg; with stand 6 kg LG
Warranty	3 years, including panel burn-in On OLED, images left static for long periods can leave permanent marks; MSI covers this risk under warranty. Terms can vary by country. MSI	—
Brightness and contrast	—	400 cd/m² typical (minimum 320); 1000:1 typical contrast (minimum 700:1) LG
Colour and HDR	—	99% sRGB typical (minimum 95%, CIE1931); 16.7 million colours; HDR10; factory calibrated HDR10 signals are accepted; LG lists no DisplayHDR certification in the spec table, and typical brightness is 400 cd/m². LG
