What people are saying

Rated 5 out of 5 by from Ultrawide, ultraspeed and ultrasharp! I’ve been gaming and working on this monitor now for around three months. It is fantastic for both productivity and playing your favorite video games. The colors are quite accurate. A couple of professional reviews have surfaced now on YouTube to back this. My monitor is effectively overclocked to 160 hz. I’m currently running on the Fast preset and not the Fastest setting. The gray to gray is around 4 milliseconds on the Fast setting. I got a little flickering on various games and applications on the Fastest preset that is the stated 1 millisecond response time. I can tell you first hand I notice no difference in responsiveness. It’s great for everything from adventure games like Tomb Raider to Esports titles. I play a lot of Warzone on the monitor and love it. Jump in and enjoy. The base takes up a decent amount of desk space. Be aware of that. At 400 nits the HDR experience is not mind blowing but I don’t feel like I’m missing out. I purchased the monitor at Micro Center in Brentwood, MO.

Rated 1 out of 5 by from Panel died within 6 months Monitor was mostly great for about 6 months. Had vibrant colors and great refresh rates. It did run really hot and had light would bleed around the edges. However the panel died after about 6 months. Thanks to another website tricking me into buying it used I get no warranty coverage. So even though this monitor has only been on the market for about a year they wont fix the panel. I think a panel at that price should work for at least a year and if not the manufacturer should repair it regardless of where or how it was purchased.

Rated 5 out of 5 by from Amazing Monitor! Absolutely love this monitor! I’ll never go back to a 16:9. UltraWide is where it’s at! And LG has released an amazing product! Works flawlessly with my 2080 Ti! The colors are spot on! Vibrant and beautiful! Input lag is nonexistent as well! You will NOT regret your purchase!

I bought this monitor and I really like it. There's one thing I can't find anywhere, in the spec sheet list it says "YUV422 can do 3440*1440 @ 160 hz for 10 bit color depth". How can I activate this profile/setting? Not available in Nvidia control pan.

How do I get the adaptive ring light on the back to work?

Asked by: lastpick
The LG 34'' UltraGear™ 21:9 Curved WQHD Nano IPS 1ms 144Hz HDR Gaming Monitor with G-SYNC® Compatibility, Model # 34GN850-B does not feature Sphere Lighting. It only has a red ring in the back that does not light up. Only models with Sphere Lighting have a ring in the back that lights up...^IFV
