Fastest IPS UltraWide Gaming Monitor

DisplayNinja staff



Thanks to its large 34′′ curved screen and vivid colors, the LG 34UC89G offers both an immersive and sensitive gaming experience as well as the fast 166Hz overclockable refresh rate, a fast response time of 5ms, and NVIDIA G-SYNC.

Because of its low screen size resolution, though, it’s not as good for creating content or any other work where you need to read or type a lot.

Image Quality

The LG 34UC89G-B ensures vivid, accurate and reliable colours, based on an IPS panel with true 8-bit color depth and over 99.9 percent of the sRGB color gamut.

In addition, because of the 178-degree wide viewing angles, the image will not shift in brightness , contrast or color when viewed from the sides or below / above.

Other LG 34UC89G IPS ultra wide monitor specifications include a standard 300-nit peak brightness and 1,000:1 static contrast ratio.

The screen is not going to get as bright as certain HDR displays and the blacks are not going to be as deep as on VA panels, but the monitor has other features to make up for it – mainly G-SYNC and 166Hz.

As we’ve said, we don’t recommend the LG 34UC89G for any other use but gaming, web-surfing, watching movies, and other casual activities.

On the 34′′ LG 34UC89 G screen, the 2560 UltraWide High Definition resolution offers a pixel density of 81 pixels per inch.

This makes for small screen real estate and smudgy details of small items such as text that is not noticeable in video games and movies, but it is embarrassing if you also intend to use the monitor for work.


The LG 34UC89G input lag is around 14ms, which means that no delay will be noticed by even professional gamers.

Additionally, 5ms response time speed effectively removes ghosting and trailing artifacts of fast-moving objects within games.

The native 144Hz refresh rate can be overclocked up to 166Hz, but even at 144Hz the movement clarity is amazing and guarantees a more enjoyable fast-paced gameplay.

Finally, the NVIDIA G-SYNC technology removes all screen tearing and stuttering if you have an NVIDIA GeForce graphics card GTX 650 Ti or newer.

You can also use the monitor with AMD cards, but not the variable refresh rate technology; and since G-SYNC adds to the price, you should get the FreeSync version of the monitor, the LG 34UC79G, which is also cheaper.

The 21:9 ultra-wide aspect ratio gives you a wider field of view which, in addition to offering a more immersive gameplay, can also be a big advantage in competitive games as you can spot the enemies faster from the sides.

Some competitive games, precisely for this reason, force the aspect ratio of 16:9 on ultra-wide monitors leaving you with black bars on the sides of the screen or with a stretched image. Check out what games the 21:9 format supports.


The LG 34UC89G monitor also offers a variety of useful features including On-Screen Power, Screen Split, and Reader, Video, Cinema, Dark Space, Color Loss, two FPS, one RTS, and two customizable presets.

For First-Person shooters, you can also put a customizable crosshair on the screen to improve accuracy.

Next, the Black Stabilizer feature brightens up the dark sections of the picture that can expose objectives or attract players in the dark.

Note that the monitor is not equipped with NVIDIA ULMB (Ultra Low Motion Blur) technology that is sometimes coupled with G-SYNC.

Design & Connectivity

The LG 34UC89G G-SYNC gaming monitor has a versatile design with height adjustment of up to 120mm, screen tilt of -5°/20° and VESA mount compatibility of 100 x 100mm although there is no swiveling option.

Connectivity includes a DisplayPort 1.2, a headphone jack, a fast-charging dual-USB 3.0 socket, and an HDMI 1.4 that maxes out at 60Hz at 2560 quelque 1080.

Price & Similar Monitors

The price of the LG 34UC89 G is $799.99 MSRP though it is frequently available for $650-$700.

The LG 34UC89 G is for you if you are looking for a monitor that delivers both an immersive picture quality and a responsive gameplay.

Check out the Dell AW3418DW, if you’re willing to sacrifice a bit of gameplay fluidity for higher resolution.


The LG 34UC89 G overall perfectly combines immersion and responsiveness in gameplay.

The picture would be significantly better if it had a higher resolution, but that would also make it more challenging on your PC system which would result in a less fluid gameplay.

And the LG 34UC89 G is the ideal monitor if you want to take competitive and fast-paced gaming to the next level.

In case you prefer more graphically-oriented games such as RPGs, consider a 3440×1440 60Hz-75Hz ultrawide monitor instead.

Thanks to its large curved screen and vibrant IPS panel colours, the LG 34UC89 G offers an immersive gaming experience. It also ensures flawless performance with G-SYNC, low input lag, fast response time and a refresh rate of up to 166Hz. However, its low resolution makes this monitor suitable mainly for gaming only.
