  • Excellent gaming performance
  • High-refresh rate IPS panel
  • Good color accuracy
  • Supports Adaptive-Sync
  • Low contrast ratio
  • Mediocre color accuracy


LG 34GN850-B reproduces most colors well except for dark and saturated colors, thanks to its Nano IPS gaming monitor with 1ms response time and 144Hz refresh rate. It's not the best choice for dark room gaming due to its low contrast ratio and its horizontal viewing angles aren't as good as other IPS monitors.
This rundown provides our analysis on 8 third-party reviews. The sentiment scores, summaries, and key takeaways that we select are based on these reviews and may differ from the original publication.



Sentiment Score[*] 80%
Reviewers from Digitaltrends have found the following[***]:
The LG 34GN850 has a Nano-IPS panel (LG's spin on Quantum Dots) with 3440 x 1440 resolution. It has a 160Hz refresh rate, 98% DCI-P3 coverage, 1ms response times, Adaptive-Sync, HDR400, and more. You'll only find better image quality from the best 4K and 5K monitors, which are often more expensive.

Sentiment Score[*] 76%
Reviewers from Rtings have found the following[***]:
The LG 34GN850-B has a simple design that looks like most gaming monitors in LG's UltraGear lineup. Sadly, its ergonomics are rather poor and although its IPS panel has decent horizontal viewing angles, it's not as good as most IPS monitors. The monitor has an sRGB mode that displays most colors accurately, however, white balance is a bit off and the color temperature is warmer than our 6500K target. The LG has a higher refresh rate, a significantly faster response time, and it supports HDR.

  • Excellent gaming performance
  • Good color accuracy

Sentiment Score[*] 69%
Reviewers from Techadvisor have found the following[***]:
LG UltraGear 34GN850 uses a Nano IPS panel that promises the colour gamut of IPS technology with the latency of TN technology. It's an easy to navigate interface and makes input selection or changing to one of a wide range of presets extremely easy. The only snag is that because this is a gamer orientated design, the settings menu doesn't offer specific colour temperatures or numerical Gamma settings. The panel is HDR400 certified, which isn't the best available, but better than using the HDR effect mode on content that doesn't have the extra data.

  • Extremely low latency
  • Supports both Nvidia and AMD variable refresh rates
  • Low latency
  • Lacks support for G-Sync and FreeSync


Sentiment Score[*] 78%
Reviewers from Techradar have found the following[***]:
LG UltraGear 34GN850 is a full-featured 34-inch curved gaming monitor. The Nano IPS panel sports 3,440 by 1,440 pixels and a 160Hz refresh. You also get both Nvidia G-Sync and AMD FreeSync Premium support. But the panel lacks VESA DisplayHDR400 certification. It also lacks local dimming and tops out at 400 nits.
