LG 34UC89G Review: 2560×1080 144Hz G-SYNC UltraWide Curved Gaming Monitor

The LG 34UC89G delivers both an immersive and responsive gaming experience thanks to its big 34″ curved screen and vibrant colors as well as the rapid 166Hz overclockable refresh rate, a quick 5ms response time speed, and NVIDIA G-SYNC.

However, due to its low resolution for the screen size, it’s not as good for content creation or any other work where you need a lot of screen space or to read and type a lot.

Image Quality

Based on an IPS panel with true 8-bit color depth and 100% coverage of the sRGB color space, the LG 34UC89G-B ensures vibrant, precise, and consistent colors.

Furthermore, the image won’t shift in brightness, contrast, or color when it’s viewed from the sides or below/above due to the 178-degree wide viewing angles.

Other specifications of the LG 34UC89G IPS ultrawide monitor include a 300-nit peak brightness and a 1,000:1 static contrast ratio which is standard.

The screen won’t get as bright as certain HDR displays and the blacks won’t 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.

The 2560×1080 UltraWide High Definition resolution provides a pixel density of 81 pixels per inch on the 34″ screen of the LG 34UC89G.

This makes for little screen real estate and smudgy details of small items such as text which is not noticeable in video games and movies, but it’s bothersome if you intend on using the monitor for work as well.

Performance

The LG 34UC89G input lag is around 4ms which is very good meaning that even professional gamers won’t notice any delay.

In addition, the response time speed of 5ms efficiently removes most of the ghosting and trailing artifacts of fast-moving objects in games.

You can overclock the native 144Hz refresh rate up to 166Hz, but even at 144Hz, motion clarity is stunning and ensures 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.

The 21:9 ultrawide aspect ratio provides you with a wider field of view which, besides offering more immersive gameplay, can also be a big advantage in competitive games as you can spot the enemies from the sides more quickly.

Some competitive games, force the 16:9 aspect ratio on ultrawide monitors precisely for that reason leaving you with black bars at the sides of the screen or with a stretched picture. Check what games support the 21:9 format.

Features

Moving on, the LG 34UC89G monitor also offers plenty of useful features including On-Screen Control, Screen Split, and Reader, Photo, Cinema, Dark Room, Color Weakness, two FPS, one RTS, and two customizable picture presets.

You can also place a customizable crosshair on the screen to increase your precision in first-person shooters.

Next, the Black Stabilizer feature can brighten up the dark parts of the image which can reveal objectives or players luring in the dark.

Note that the monitor does not have the NVIDIA ULMB (Ultra Low Motion Blur) technology which is sometimes paired with G-SYNC.

Design & Connectivity

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

Connectivity includes DisplayPort 1.2, a headphone jack, a dual-USB 3.0 hub with fast charging and an HDMI 1.4 port which maxes out at 2560×1080 at 60Hz.

Price & Similar Monitors

The LG 34UC89G price is usually around $700 which is rather expensive considering that you can buy the LG 34GP83A with faster response time and a higher 3440×1440 resolution for ~$800.

Alternatively, consider the cheaper LG 34GL750, which is the FreeSync version of the 34UC89G. It’s G-SYNC Compatible, so FreeSync will work with both AMD and NVIDIA graphics cards without any issues.

Conclusion

Overall, the LG 34UC89G offers an immersive and responsive gaming experience, but it’s an older model that is overpriced by today’s standards – unless you can find it at a big discount.
