What people are saying
Rated 5 out of 5 by from quality you can not go wrong with LG brand. all my TV’s and monitors are LG. I love the ultra wide screen you can do things side by side or just lays out well full screen. the stand will raise tall enough to get it where I want it I no longer needed my monitor stand which leaves more room on my desk. the curved screen is nice. and the back of the monitor looks really nice. good brightness and excelant color.

Rated 4 out of 5 by from Good Enough I have had this for a few years now and it has worked well. No problems at all. Though i will say that perhaps a version with a higher resolution would be nice.

Rated 4 out of 5 by from Good gaming monitor I really like this monitor. I had a 34 AOC which was good, but this LG 34" 21:9 is awesome. I got it for the price and it was 144hz. I do iRacing, and once I got this setup I went WOW what a difference with 21:9 view I will not go back. It took me a couple of days playing with the color and gaming settings. The picture display is not as good as my LG 2340 but not that far off thou. The only problem I have with this monitor and it is only reason I did not give it a 5 is the JOYSTICK button for setting the display and any other thing you might need to do. Outside of that, too me this is a GREAT monitor. l

can you build a gaming system and use three of the 34UC79G-B monitors for your display?

Asked by: mAssterch1ef
Using three of the LG 34" Class 21:9 UltraWide® Full HD IPS Curved Gaming Monitor (34” Diagonal), Model # 34UC79G-B to build a gaming system will depend on what configuration you use and on what device you are using to build the gaming system with. It will also depend on if you have a Graphics card that will support three monitors...^IFV

I bought a VESA 100 compatiable wall mount (based on reading that it was compatiable with such mounts) but the indentiation on the back of the panel does not allow the mount to fit into the space necessary. How do I mount this monitor?

Asked by: mtgent
Add a stack of washers between the mount and the monitor. Most mounts come with plastic spacers for this purpose but washers can be used instead if spacers were not included.
