The 34-inch LG 34UC79G-B, a slightly curved, ultra-wide monitor designed for gameplay, offers plenty of ports and gamer-friendly settings.

  • +

    AMD FreeSync enabled. Speedy refresh rate. Game-friendly features.

  • -

    Slightly skewed greens. No speakers. Stingy warranty.

While some may cry for greater resolution, we think the 34UC79G goes far beyond “just fine” the way it is. A lower pixel count means higher framerates which translates to smoother motion and better gaming.

As the window to our digital world, the importance of a good monitor cannot be overstated. A lovingly built gaming rig will be all for naught if the video it produces is rendered as a blurry, tinted mess.

8 August 2017

Ultrawide gaming monitors are not quite as common as standard 16:9 monitors, and the LG 34UC79G is one of the few 21:9 monitors in the market that combines a high 144Hz refresh rate with a curved IPS panel.

28 July 2017

Ultra-wide displays began to appear in 2014, and the category has grown to encompass many screen sizes (34", 35" and 38" most prominently - with Samsung having just launched a 49" model), resolutions and vendors.

  • +

    Cheap for an ultrawide monitor, high refresh rate, great black levels, accessible settings menu

  • -

    Low brightness and colour accuracy, limited stand adjustments

  • +

    Native high refresh rate support combined with FreeSync and low input lag for gaming, Excellent static contrast ratio and decent factory setup, Good range of features, connections and gaming extras

  • -

    Blur Reduction mode shows noticeable strobe cross-talk, Response times not perfect and are limiting at upper end of refresh rate range, Missing side to side swivel from stand

If you've been looking for a monitor that gives you high frames per second and that wraps around your eyes the LG 34UC79G offers all of that in a reasonably priced package. FreeSync is not the main feature but its a nice addition for AMD users.

When I started testing this monitor, I was wondering why volume control of this monitor was set to 100 percent, default playback device was set correctly to “LG ULTRAWIDE” yet there was no sound coming out of this monitor. Turns out, this monitor does not have built in speakers.

  • +

    Monitor ships in well protected box lined up with styrofoam and wrapped in plastic bags. All required cabling is included - DisplayPort and HDMI, both able to carry video and audio signals. This LG monitor is very wide and easily replaces two 17” monitors placed side-by-side.

  • -

    One of problems with this monitor is uneven backlight (widely known as screen bleeding). To test for uneven backlight, I have created test image with resolution 2560x1080 and filled it with black color, then displayed this image in fullscreen mode in very dark room with all settings of monitor set...

After weeks of searching for a nice curved, 144hz monitor, I decided to buy this one off the shelf at Fry's. The only thing I was afraid of was pixel density, considering it was 34 inches and is 1080p. But holy cow was I incorrect. It is absolutely stunning, and I play about 2 feet from my monitor.

Wanted something big and bright when I started to play with Linux and this big boy came thru. Everything is crisp, well defined, and serves my simple needs. Not my first LG product and probably not my last. Guess you could say a loyal LG fan.

I bought this monitor to upgrade from my 27" monitor and I have been very pleased! This monitor gives me a broader view and it has outstanding performance. I get no screen tearing ( I use an R9 390X graphics card) and the resolution/ refresh rate is amazing.
