240Hz · 0.03ms GtG
A 240Hz refresh and 0.03ms grey-to-grey response deliver razor-sharp motion over HDMI 2.1 or DisplayPort 1.4. NVIDIA G-SYNC Compatible, AMD FreeSync Premium Pro and VESA AdaptiveSync keep frames in sync.
 
Flexible Connectivity
Two HDMI 2.1 and DisplayPort 1.4 inputs handle PC and consoles, while a USB hub (one upstream, two downstream) and a 4-pole headphone jack keep peripherals and chat audio close at hand.

A 4-side virtually borderless design with rear Hexagon lighting suits any battlestation, while OLED protection features mitigate image retention. The stand adjusts for height, tilt, swivel and pivot.

Frequently Asked Questions

Does the 27GX704A-B work with PS5 and Xbox Series X?
Yes. Its two HDMI 2.1 ports support modern consoles, so the PlayStation 5 and Xbox Series X run at QHD with high frame rates. On a PC, both HDMI 2.1 and DisplayPort 1.4 drive the panel at the full 240Hz.
Is the panel glossy or matte?
It is a glossy (Glare) WOLED panel, which gives deeper blacks and punchier, more saturated highlights - ideal in controlled lighting. If you prefer a matte anti-glare finish for bright rooms, LG's 27GS95QX is the alternative with the same speed.
How bright is the 27GX704A-B?
Thanks to Micro Lens Array+ (MLA+), it reaches around 275 nits typical brightness - roughly 37.5% higher SDR brightness than standard MLA - and peaks at 1300 nits in HDR, with VESA DisplayHDR True Black 400 certification.
What should I know before buying the 27GX704A-B?
It runs at 240Hz (not the 480Hz of the 27GX790A), uses a glossy panel and has no built-in speakers (a 4-pole headphone jack handles audio). It includes a USB hub, rear Hexagon lighting and OLED protection, and carries a 2-year warranty covering the panel.
Singular Expert Insight
The 27GX704A-B pairs a bright, glossy MLA+ WOLED panel with 240Hz speed and a USB hub - a great all-rounder for QHD gaming. Pick the anti-glare 27GS95QX instead if you game in a bright room and prefer a matte finish. If you chase the highest refresh rate, LG's 27GX790A pushes the same size to 480Hz.

Buyer's Guide

Buy it if
You want a bright glossy 240Hz WOLED with MLA+, deep blacks and a USB hub for competitive QHD gaming.
Skip it if
You need a matte anti-glare panel for bright rooms, built-in speakers, or a 480Hz refresh rate.
Also consider
LG 27GS95QX for an anti-glare 240Hz version, or LG 27GX790A for a 480Hz WOLED panel.
