LG 34UC89G-B Preview: Curved Ultra-Wide 144Hz Gaming Monitor With G-SYNC

LG 34UC89G-B


LG has released a new gaming monitor dubbed as the LG 34UC89G-B. It’s a giant 34-inch display with an ultra-wide resolution and curved screen for an immersive viewing experience. Moreover, the monitor sports a native 144Hz refresh rate that’s overclockable to 166Hz, a quick 5ms response time speed, and Nvidia G-Sync technology for a buttery smooth gameplay.

Image Quality

The LG 34UC89G display features an IPS panel which delivers the impeccable 178-degree viewing angles and accurate true 8-bit colors that cover over 99% of the sRGB color space making the monitor adequate for professional color-critical work as well. In video games, the precise and consistent colors allow you to fully immerse into the gaming world with vibrant and crisp imagery.

The only downside of the monitor is its rather low resolution, at least when we consider its price. The LG 34UC89G-B offers the screen resolution of 2560×1080 which when displayed on its 34-inch screen results in a solid pixel density of 81.72 pixels per inch. It’s equivalent to the Full HD resolution displayed on a 27-inch screen monitor.

However, the combination of its gigantic, curved, and thin-bezel design along with the color vibrancy of an IPS panel and medium pixel density promises an immersive image quality regardless of its inferior resolution.


The LG 34UC89G-B monitor includes all of the common LG features such as Black Stabilizer, Dynamic Action Sync, Crosshair, On-Screen Control, and Screen Split 2.0. The black stabilizer increases the visibility in the dark scenes of video games while the dynamic action sync allows for lesser input lag. These features are also automatically enabled in the pre-calibrated gaming presets of the monitor. With the crosshair feature, you can fix a custom crosshair overlay onto the screen for better precision in competitive FPS games.

The On-Screen Control allows you to effortlessly adjust all of the OSD (On-Screen Display) settings such as brightness, contrast, and other parameters, in a desktop application. Moreover, you can use the Screen Split feature to divide your screen into different layouts for easier multi-tasking activities.

In the On-Screen Control application, you can assign different picture presets to certain applications, so whenever you open an FPS video game, for instance, the LG 34UC89G-B will apply the FPS preset to the screen. Other picture presets include Cinema, Photo, Reader, Color Weakness, Dark Room, RTS Game, as well as custom modes for both gaming and regular preset.


Although most of LG displays feature FreeSync, they decided to go with G-Sync for the LG 34UC89G-B model. G-Sync allows you use the full potential of your Nvidia GTX compatible graphics card by synchronizing its frame rate to the monitor’s refresh rate. Within this dynamic range, all screen tearing and stuttering will be eliminated and the FPS (Frames Per Second) rate will be more stable, while the input lag is reduced. As opposed to FreeSync, G-Sync monitors offer a wider dynamic range which makes it more viable in certain cases.

The LG 34UC89G-B G-Sync monitor provides 144Hz native refresh rate, but it also states that with a powerful enough graphics card, you can easily overclock it to up to 166Hz. The response time speed of 5ms should eliminate most of the ghosting in the fast-paced video games. Overall, the monitor offers all the specs a gamer may need for a responsive, smooth, and enjoyable gaming experience. Add to that its beauteous curved screen with thin bezels, and you can immerse into video games for hours to an end.

Design and Connectivity

Unlike their usual ArcLine base design with simple black and silver colors, the LG 34UC89G-B includes some red color accents and curvy lines which indicate that the monitor’s aimed at gamers. In addition to the VESA mount compatibility, the ergonomics include the -5, 20 degrees tilt ability as well as 120 mm of height adjustment. The screen coating used is 3H matte anti-glare. The thin bezels along the slight 38000R curvature make for a cinematic viewing experience. Connector ports consist of a DisplayPort for G-Sync, and an extra HDMI 1.4 that maxes out at 60Hz. There are two USB 3.0 downstream, one USB 3.0 upstream, and the headphones jack present as well.

Price & Similar Monitors

The LG 34UC89G-B’s price of $1,000 is quite hefty, to say the least, considering its rather low 2560×1080 resolution. In fact, you can get the practically same monitor but with FreeSync instead of G-Sync for nearly half the price; check out the LG 34UC79G-B gaming monitor. Naturally, if you already possess a powerful high-end Nvidia graphics card, you will want a G-Sync monitor, but then again, not a 1080p one – certainly not at this price point. So, we’re expecting a price drop for the LG 34UC89G-B monitor, any day now.


Although the LG 34UC89G-B will repulse a majority of users due to the low screen resolution for its current price, some may find it desirable. After all, you are getting a smooth gameplay experience thanks to G-Sync and 166Hz refresh rate, along with a huge and curved ultra-wide screen. The way I see somebody considering the LG 34UC89G-B 166Hz gaming monitor is if they had a powerful enough GPU for such refresh rate at 1080p, but not at 1440p – and they’d want to invest in an awesome gaming monitor rather than a better graphics card.

    Other than the resolution. How was the image quality in comparison to the Z35P? Was there any ghosting/Smearing? I guess I’m really wondering if the IPS panel provides that much more quality/response time than that of the VA panel in the Z35P

    Does this monitor compatible with my Acer Predator Laptop G9-592 GeForce 980M? I’ve always wanted to have an IPS, G-sync, Ultrawide Monitor with 144 Refresh Rate and i think this is what i am looking for my gaming and professional works. I hope anyone can give me an answer. thank you in advance.

    Hi there!
    It is. Source:
    Just make sure to connect the monitor via the DisplayPort.

    Hi, sorry for the late reply, didn’t get notified by Disqus.

    The Acer Predator Z35P does have more ghosting than the LG 34UC89G-B which has an overall smoother performance; although that’s mainly because of the faster refresh rate and lower resolution.

    In this case, the IPS does provide better response time as well as viewing angles. But the VA panel delivers notably better blacks tones, and has a higher resolution. So, it depends whether you prefer better image quality or performance.
