Specification	MSI MPG 272URX QD-OLED	LG UltraGear 27GP750-B
Release year	2025	2021
Panel	26.5-inch flat QD-OLED; 3840 × 2160; 10-bit (1.07 billion colours) In QD-OLED, light from a blue OLED layer is converted to red and green by quantum dots; because each pixel emits its own light, blacks switch off completely. 4K in the 27-inch class gives very sharp text at about 166 ppi. 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 (adaptive range 48–240 Hz); 0.03 ms GtG 4K 240 Hz is reached over DisplayPort 2.1a or HDMI 2.1. 0.03 ms is pixel transition time, not total input lag. 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
Adaptive sync	G-SYNC Compatible; AMD FreeSync Premium Pro Matching refresh rate to the GPU frame rate reduces tearing and stutter. MSI	—
Brightness and HDR	SDR 250 nits; HDR 450 nits at 10% APL, 1000 nits peak at 3% APL; DisplayHDR True Black 400 1000 nits is reached only when a very small part of the screen is bright; OLED brightness drops markedly on a full white screen. True Black 400 is the VESA tier for OLEDs that also measures black level. MSI	—
Colour and contrast	DCI-P3 99%, Adobe RGB 98%, sRGB 138% (CIE 1976); 1,500,000:1 typical contrast 138% of sRGB means the panel can oversaturate standard content; use the sRGB mode for accurate colour. MSI	—
Video inputs	1 × DisplayPort 2.1a (UHBR20); 2 × HDMI 2.1 (UHD 240 Hz); 1 × USB-C (DP Alt Mode, 98 W PD) UHBR20 offers 80 Gbit/s, enough to carry 4K 240 Hz 10-bit without compression, provided the GPU also supports DP 2.1 UHBR20. USB-C delivers video, data and up to 98 W laptop charging over one cable. MSI	—
USB and audio	2 × USB-A 5 Gbit/s; 1 × USB-B 5 Gbit/s (upstream); headphone out; no built-in speakers MSI	—
KVM and multi-view	KVM; PiP and PbP KVM shares a keyboard and mouse connected to the monitor between two computers. PiP shows one source in a small window, PbP shows two sources side by side. MSI	—
Stand and mounting	Tilt -5°/20°; swivel ±30°; pivot ±90°; height 0–110 mm; VESA 100 × 100 mm 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
Power	Internal power board; 100–240 V, 50/60 Hz No external power brick is needed. MSI	External adapter; 45 W typical, 48 W maximum; under 0.5 W in sleep LG
Size and weight	With stand 610 × 242 × 422 mm, without stand 610 × 69 × 356 mm; net 8.1 kg MSI	Without stand 614.2 × 364.8 × 51.7 mm, 3.9 kg; with stand 6 kg LG
Warranty	3 years, including OLED burn-in Coverage and duration may vary by country. MSI	—
Variable refresh	—	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
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
Connections	—	2 × HDMI; 1 × DisplayPort 1.4; 3.5 mm headphone out A DisplayPort cable is in the box. There are no built-in speakers or USB hub. LG
