Specification	MSI MAG 271QPX QD-OLED E2	LG UltraGear 27GP750-B
Release year	2024	2021
Panel	26.5-inch flat QD-OLED; 2560 × 1440 (WQHD), 16:9; anti-reflection surface 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 turn fully off. 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 rate	240 Hz; Adaptive-Sync 48–240 Hz; 2560 × 1440 at 240 Hz over DisplayPort 1.4a, both HDMI 2.1 ports and USB-C (DP Alt) 240 Hz shows 240 frames per second for smooth, clear motion in fast games, provided the graphics card can produce that frame rate. Adaptive-Sync matches the display’s refresh to the card’s frame rate to prevent tearing. MSI	—
Response time	0.03 ms (GtG) This is grey-to-grey transition time; OLED’s very fast transitions reduce motion blur, but it is not the same as total input lag. MSI	—
Brightness and HDR	SDR 250 nits (typical); HDR 450 nits at 10% window and 1000 nits peak at 3% window; VESA DisplayHDR True Black 400 OLED brightness falls as the lit area grows; 1000 nits appears only in very small bright highlights. True Black 400 certifies deep blacks with at least 400 nits HDR performance. MSI	—
Colour	10-bit (1.07 billion colours); 99.1% DCI-P3 and 100% sRGB coverage (CIE 1976); ΔE ≤ 2 The wide gamut gives saturated colour in HDR and games; MSI states colour accuracy as ΔE ≤ 2. MSI	—
Contrast and viewing angle	1,500,000:1 (typical); 178° / 178° MSI	—
Inputs	2 × HDMI 2.1 (HDCP 2.3), 1 × DisplayPort 1.4a, 1 × USB-C (DP Alt, 15 W PD), headphone out The HDMI 2.1 inputs support WQHD 240 Hz on consoles at 48 Gbps (Console Mode). USB-C with 15 W only charges small devices such as phones and is not enough to charge a laptop; the port runs at USB 2.0 speed and there is no separate USB hub. MSI	—
PiP / PbP	Picture-in-picture and picture-by-picture support Shows two sources at once: in PiP one is a small window, in PbP the two sit side by side. MSI	—
OLED care and cooling	MSI OLED Care 2.0; fanless design with graphene film and custom heatsink OLED Care includes protection functions that reduce the risk of static images leaving marks (burn-in). With no fan, it makes no noise while running. MSI	—
Stand and mounting	Tilt -5°/20°, swivel ±30°, height 0–110 mm, pivot ±90°; 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
Warranty	3 years including OLED burn-in Terms may vary by country. MSI	—
Power consumption	40 kWh/1000 h in on mode; standby 0.5 W; off 0.3 W; energy class G MSI	—
Size and weight	609 × 242 × 416 mm with stand; 609 × 72 × 362 mm without; 5.3 kg without stand MSI	Without stand 614.2 × 364.8 × 51.7 mm, 3.9 kg; with stand 6 kg LG
In the box	DisplayPort cable, HDMI cable, power cord, quick guide MSI	—
Refresh and response	—	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
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
Power	—	External adapter; 45 W typical, 48 W maximum; under 0.5 W in sleep LG
