Model	—	27GX790A-B (US version 27GX790A-B.AUS) LG’s US spec sheet carries a 2024 copyright; LG Brazil lists the model as a 2025 product. LG
Panel	—	26.5-inch (27-inch class) OLED, 16:9 The actual viewable diagonal is 26.5 inches. LG
Resolution and pixel pitch	—	2560 × 1440 (QHD); 0.2292 mm pixel pitch QHD at 27 inches means lower pixel density than 4K; small text looks less crisp but high frame rates are easier to reach on the GPU. LG
Response time	—	0.03 ms (GtG) Grey-to-grey pixel transition time; it is not input lag. LG
Brightness	—	Typical 275 cd/m² (min 250); HDR peak at 1.5% APL typical 1,300 cd/m² (min 1,040) 1,300 nits applies only to small highlights covering 1.5% of the screen; on a full white screen OLED automatic brightness limiting kicks in. LG
Contrast	—	1,500,000:1 (typical) OLED pixels can switch fully off, so black level is near zero; LG’s page notes the figure is measured at 25% APL. LG
Colour	—	DCI-P3 98.5% (CIE 1976); 10-bit (1.07 billion colours) The sheet lists a paper calibration report in the box. LG
HDR	—	HDR10; VESA DisplayHDR True Black 400 True Black is the VESA HDR tier for very low black-level displays such as OLED. LG
Variable refresh	—	VESA AdaptiveSync; NVIDIA G-SYNC Compatible; AMD FreeSync Premium Pro Variable refresh matches the panel to the GPU frame rate to reduce tearing and stutter. LG’s page also lists VESA ClearMR 21000 certification. LG
Screen surface	—	Anti-glare, low-reflection front polariser LG
Inputs	—	2× HDMI (HDMI 2.1 FRL compliant); 1× DisplayPort 2.1 FRL is the high-bandwidth transfer mode of HDMI 2.1. There is no USB-C video input. LG
USB and audio	—	USB 3.0: 1 upstream, 2 downstream; 4-pole headphone out (sound + mic); DTS Headphone:X No built-in speakers are listed. LG
Power	—	External adapter, 100–240 V; under 0.5 W in sleep, under 0.3 W off The sheet does not list typical power consumption. LG
Burn-in care	—	OLED Care LG says the feature helps prevent burn-in from static high-contrast images left on screen for long periods but may not prevent all image retention. LG
Size and weight	—	With stand 23.8 × 22.8 × 9.8 in (raised), 20.5 lb; without stand 23.8 × 13.8 × 1.8 in, 11.2 lb About 9.3 kg with stand, about 5.1 kg without. LG
