27" IPS 100Hz Full HD Monitor

The LG Electronics 27BA400-B is a 27 inch flat-panel display built on an IPS panel with a 1920 x 1080 resolution and a 100Hz refresh rate. It suits office workers, students and home users who need a larger screen for everyday productivity and casual media viewing. The anti-glare coating and 178° viewing angles help keep the image readable from different positions.

HDMI 1.4 Limits at 100Hz

The monitor provides two HDMI 1.4 ports for video input. This interface caps the maximum refresh rate at 100Hz for the native 1080p resolution, so the panel runs at its rated speed without requiring a newer cable standard. The colour gamut covers 72% NTSC (CIE1931) and brightness reaches 250 cd/m², which is adequate for indoor lighting but not for HDR content or colour-critical work.

Tilt Stand and 75x75 VESA Mount

Installation is straightforward: attach the included stand for -5° to 15° tilt adjustment or remove it to use the 75 x 75mm VESA pattern with a compatible arm or bracket. The unit weighs 7.72 lbs with the stand and 6.83 lbs without. Built-in speakers and a 3-pole headphone jack handle basic audio, though the headphone output carries sound only and does not support a microphone.

Questions about this item

Which version of the 27BA400-B should I choose?

The 27BA400-B is a single 27" Full HD IPS model with a 100Hz refresh rate, built-in speakers and a tilt-only stand; there are no alternative capacities or panel variants listed.

What does the 100Hz refresh rate deliver in daily use?

A 100Hz panel refreshes the image 100 times per second, giving noticeably smoother motion than 60Hz for office scrolling, video playback and casual gaming at 1920 x 1080 resolution.

What does the HDMI 1.4 interface cap in practice?

Each of the two HDMI 1.4 ports supports up to 1920 x 1080 at 100Hz, so the monitor’s full resolution and refresh rate are available without bandwidth limitation.
