What people are saying

Rated 5 out of 5 by from So good you wouldn’t know it’s just mid range Extremely happy. I’d be be honest LG wouldn’t be my first choice for anything but this monitor changed my opinion. Read a lot of good reviews. There’s no defect, just perfect.

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.

Asked by: NotTheHerbie

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.
