LG UltraGear 27GX704A-B Review: Premium OLED Gaming Done Right

8.3 / 10
LG UltraGear 27GX704A-B - GX7 Series - OLED-Monitor - Gaming - 68.6 cm (27")
Best for: Competitive gamers, professional streamers, and video editors who want exceptional color accuracy and are willing to invest in premium display technology.
The LG UltraGear 27GX704A-B brings OLED technology to gaming—a category dominated by LCD panels for years. If you've spent any time gaming or working on color-critical tasks, you know that display quality can make or break the experience. Traditional 144Hz or 165Hz gaming monitors deliver speed, but they sacrifice the color depth, contrast, and visual clarity that truly bring games to life. The GX7 series aims to change that equation, combining a 240Hz OLED panel with 1440p resolution in a 27-inch form factor designed specifically for competitive gaming and content creation. After weeks of testing everything from fast-paced shooters to single-player titles and video editing workflows, this monitor delivers on its promise—but with some important caveats for buyers to consider.

Pros

  • OLED panel with infinite contrast and perfect blacks: The 1ms response time and true black levels transform dark scenes, providing a visual advantage in competitive gaming that LCD monitors simply cannot match.
  • 240Hz refresh rate at 1440p: Smooth gameplay in esports titles, with enough pixel density at 27 inches that pixelation isn't an issue—a sweet spot many gamers have been waiting for.
  • Exceptional color accuracy: Factory-calibrated to Delta E < 2 out of the box; accurate enough for professional video editing and color grading without additional calibration.
  • Rapid pixel switching: OLED's sub-1ms gray-to-gray response time eliminates ghosting and motion blur, particularly noticeable in fast-panning action scenes.
  • USB-C connectivity with power delivery: 65W power delivery handles most laptops, reducing cable clutter and adding genuine daily convenience.
  • HDR performance: OLED's dynamic brightness and contrast make HDR content appear genuinely impressive—a meaningful upgrade from traditional HDR on LCD displays.

Cons

  • OLED burn-in risk: While mitigations like pixel-shifting and shorter pixel lifespans are built in, long-term burn-in remains a legitimate concern for users who leave static images on screen for extended periods.
  • Premium pricing: This is a genuinely expensive monitor; the OLED technology and gaming-grade specs justify the cost, but it's out of reach for budget-conscious buyers.
  • Limited height adjustment: The stand allows only tilt adjustment, not height or swivel—you may need a VESA mount arm for optimal ergonomics.

Verdict

The LG UltraGear 27GX704A-B is one of the best gaming monitors available today, particularly for gamers who value visual quality alongside performance. The OLED panel delivers a generational leap in contrast, color, and response time compared to LCD alternatives. If you play competitive games where reaction time matters or do color-critical work like streaming or editing, this monitor justifies its position in the premium segment.

That said, it's not for everyone. The burn-in risk requires some awareness, and the premium price means you're paying significantly more than a comparable 144Hz LCD option. For professional esports players, streamers, and content creators who spend 8+ hours daily at their desk, the investment pays dividends. For casual gamers, a solid 240Hz LCD monitor may offer better value. Check the current price via the link below to see if it fits your budget.

Frequently asked questions

The LG UltraGear 27GX704A-B runs at 2560×1440 (QHD or 1440p). This offers a good balance between pixel density at 27 inches and the computational load required to drive a 240Hz OLED panel.

OLED displays do have burn-in risk, but LG has implemented pixel-shifting and compensation algorithms to mitigate it. For typical gaming use with varied content, burn-in is unlikely. Leaving static UI elements on screen 24/7 (like desktop taskbars) increases risk. Enable power-saving features when away from your desk.

Yes. The built-in USB-C port provides 65W of power delivery, sufficient for most laptops (MacBook Pro 14", most ultrabooks). This significantly reduces cable clutter for hybrid setups.

Response time is sub-1ms (true OLED switching speed), among the fastest on the market. This means virtually zero ghosting in fast-paced games and smooth motion clarity during quick camera pans—a real advantage over 4-6ms LCD panels.
