LG’s newer UltraGear OLED chapter goes glossy—trading some anti-glare calm for mirror-like punch when lighting cooperates. The 27GX704A-B pairs a 27-inch QHD OLED at 240Hz and 0.03ms response with VESA DisplayHDR True Black 400, wide DCI-P3 coverage, and brightness claims up to about 1300 nits peak.
UL certifications for anti-glare, flicker-free, and low blue light sit beside hexagon lighting flair, dual HDMI 2.1, DP 1.4, USB ports, and a fully adjustable stand. OLED care tools and pixel cycles aim to keep the panel healthy between ranked sessions.
We compare glossy versus matte OLED living, examine connectivity for PCs/consoles, and outline who should prefer the anti-glare 27GS93QE-style approach instead.
The 27GX704A is the showpiece twin in LG’s 27-inch QHD OLED universe: same speed ambitions as matte-leaning cousins, different glass personality. Glossy panels can make colors feel wetter and highlights harder, especially when the room is dark and controlled. In bright messy rooms, you may see yourself between gunfights—honest constraint, not a footnote.
Motion credentials mirror modern UltraGear OLED: 240Hz and 0.03ms-class transitions for tracking that feels glued on. Feed it frames; the panel will keep up. G-SYNC Compatible and FreeSync Premium Pro certifications cover the tear-free side when enabled correctly.
HDR storytelling leans on True Black 400, huge contrast, and peak nit claims that help explosions escape the “dim OLED” stereotype in smaller windows. Typical full-screen brightness near 275 nits still means room lighting strategy matters. Dim bias lighting behind the monitor often looks better than overhead glare.
Three UL certifications—anti-glare, flicker-free, low blue light—sound paradoxical on a glossy marketing hero, but they speak to comfort engineering layered onto the panel. Use low blue light modes for late chat sessions; return to full gaming modes for ranked clarity.
Connectivity is generous: dual HDMI 2.1, DisplayPort 1.4, USB upstream/downstream for a mini hub. That lets a laptop, desktop, and console coexist with fewer KVM gymnastics. Keep high-bandwidth cables for the 240Hz PC path.
Hexagon lighting and four-side virtually borderless styling push RGB battlestation vibes. If your desk is minimal Scandinavian calm, the light engine may stay off forever—and that is fine. The stand’s swivel/tilt/height/pivot range remains the practical ergonomic win.
OLED care deserves day-one attention: automatic pixel care on standby, brightness limiters, and protection features in on-screen controls. Hide static HUDs when AFK, and do not treat the panel like an immortal LCD taskboard. Warranty and care together make ownership saner.
Note on naming: marketplace titles sometimes show 2650×1440 stylization; functionally this is LG’s 27-inch QHD UltraGear OLED class. Judge it as a glossy 1440p 240Hz OLED, not a mysterious new resolution standard. Choose it for sparkle and features; choose anti-glare OLED if reflections terrify you. Before you commit, confirm that LG 27GX704A Glossy UltraGear OLED matches the ports, clearance, and software ecosystem you already own, then re-check the Amazon About bullets against your weekly workload rather than a one-time unboxing vibe. That extra diligence is what separates a durable buy from a quick return label.

Who it's for
Gamers with darker, controlled rooms who want glossy OLED pop, 240Hz speed, and rich PC/console connectivity. Also for battlestation builders who enjoy hexagon light accents.
Who should skip it
Skip if sunlight owns your desk, you need a matte anti-glare priority, or IPS brightness-for-office is your real workload. Reflection-sensitive players should compare matte UltraGear OLEDs.
Glossy rooms, HDR highlights & hubs
Place the monitor perpendicular to windows, add bias light, and use the USB hub to clear dongle clutter. Reserve peak HDR modes for compatible games and avoid forcing HDR on every desktop app.
Setup tips & verdict
Run OLED care setup, lock 2560×1440 @ 240Hz, and test reflections at your actual sit position before final mount. Verdict: the 27GX704A is a glossy, feature-rich UltraGear OLED for players chasing maximum pop with modern care tools.
- Glossy OLED elevates perceived contrast and color “pop” in dark rooms
- 240Hz near-instant response suits serious competitive play
- Peak brightness headroom helps HDR highlights versus dimmer OLEDs
- USB hub plus dual HDMI 2.1 simplifies mixed PC/console desks
- OLED care controls and pixel cycles support longer healthy ownership
- Glossy surfaces reveal reflections if windows face the screen
- Hexagon lighting is a love-it-or-ignore-it aesthetic extra
- Title lists 2650×1440 stylization—expect standard QHD 2560×1440 class panel behavior
FAQs
How does the 27GX704A differ from the 27GS93QE?
Both chase 27-inch QHD OLED 240Hz performance, but the 27GX704A emphasizes a glossy brighter-pop experience, hexagon lighting, USB hub connectivity, and updated care/certification messaging. The 27GS93QE leans into anti-glare/low-reflection language. Room lighting should decide the winner.
Is the resolution 2650×1440 or 2560×1440?
Listings sometimes stylize QHD as 2650×1440, but this UltraGear class is the standard 27-inch QHD gaming resolution consumers know as 2560×1440. Set your GPU to the monitor’s native QHD mode. Do not hunt for a mythical 2650-wide desktop mode.
Will glossy OLED be usable in a bright office?
It can work with careful placement, but reflections are more visible than on matte treatments. Side windows are the enemy. If your desk faces uncontrolled light, prioritize anti-glare models.
How useful is the USB hub?
Upstream/downstream USB ports let you park mouse/keyboard dongles or drives on the monitor when the stand is VESA-mounted or cable path is long. It reduces reach-arounds to the PC IO. Throughput depends on the USB 3.2 implementation and host connection.
What peak brightness should I expect?
LG cites around 275 nits standard and up to about 1300 nits peak in HDR highlight scenarios. Full-screen white will not sit at peak nits continuously. HDR games with small specular highlights show the benefit most.
Do OLED care cycles interrupt gaming?
Pixel care often runs at shutdown or standby rather than mid-match. You may see occasional maintenance prompts—let them finish. Skipping care forever is how retention risk creeps up.
Is hexagon lighting required?
No—it is an aesthetic accent you can disable. The monitor’s core value is the glossy OLED panel and speed, not the light show. Use lighting if it matches your setup theme.
Can it replace my IPS work monitor entirely?
Some users do, with taskbar auto-hide and strict sleep timers. Others keep IPS for static productivity and OLED for play. Your tolerance for care habits should guide the decision. In short, treat LG 27GX704A Glossy UltraGear OLED as a fit-first purchase: if the core use case is right, the supporting features make sense; if not, keep shopping within the same category.
