What people are saying

Rated 1 out of 5 by from Dead pixel after 8 months. Have had a horrible experience with LG support. My monitor has been in "repair" for 2 months. Second repair they didn't even attempt to repair it, just sent it back to me. Every time i have gotten it back from LG support, it has more dead pixels than when i sent it in originally. Not entirely sure what the issue is here, maybe its the tech repairing it, or LG support as a whole. I have been without my monitor since early Feb. with no current end in site. I posted this review once already and it got taken down. Hopefully this time my "repair" actually gets fixed. Otherwise the monitor when it was working; was great. Had good hz, amazing color. Perfect match for my 3080. Yet my voice keeps getting drowned out as support assures me every time i send it in, that it will be fixed. Its been a nightmare of an experience.

Rated 5 out of 5 by from Great Monitor! Been running this since Aug, and it is wonderful so far, the setup was easy. Picture is clean, no dead pixels. I run this in Gamer 2 Setting, at 1440 @ 144 using the GSYNC Compatibility, and it runs great! This is my first UltraWide, and I really love the extra space, just big enough so that you aren't having to move your head to look around, so immersive, can't wait to play a driving game!

Rated 4 out of 5 by from Beautiful with minor annoyances This monitor is gorgeous and has become my default gaming appliance for a couple of devices. Clean lines and hefty so my cats can’t knock it over. It loses a star for the audio jack not working, and the other solution is to mail it in and be without the monitor for 4-6 weeks. Decisions decisions. Some games need audio...but 4-6 weeks??

When will the Support pages be available for the 34GN850-B? I purchased my monitor in October and the Support site for this monitor is still not up. FYI, it is also not possible to register this monitor from a US MyLG account. The PN is not there.

does this work with PS5?

Asked by: kik123
You will need to contact Sony about if the PS% will support 1440p resolution. The LG 34'' UltraGear™ 21:9 Curved WQHD Nano IPS 1ms 144Hz HDR Gaming Monitor with G-SYNC® Compatibility, Model # 34GN850-B has a native resolution of 3440 x 1440. Sony is considering 1440p support for its new PlayStation 5. At launch, the console supports 1080p and 4K resolutions natively. The PS5 will output to a 1440p display but at 1080p upscaled to 1440p rather than a native 1440p image. The 1440p is referring to 2560 x 1440, also known as 2.5K. It’s not absolutely clear what refresh rates would be supported running at 1440p on the PS5...^IFV

Afternoon. Will this work for my Xbox One? I have been looking to move to a monitor and I want this one. 

Asked by: Bullet2003S
Depends. I have the original xbox one and it works but won't take advantage of the full display. It basically stretches everything; the settings do not allow me to go over 1080p or 3440 x 1440. I read that the xbox one s and xbox one x both have support for these displays but I cannot confirm this since I don't have one. Hope this helps.

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
