LG 27GX704A UltraGear Glossy QHD OLED 240Hz Review

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.

✓ Pros
  • 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
✕ Cons
  • 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
