Review LG 34UC89G - Expensive ultra-wide monitor for games

LG has long been producing monitors for games with a high refresh rate, synchronization of the sweep frequency and fast response. Earlier this was enough, but users now expect more from a modern gamer monitor, so the company introduced the LG 34UC89G.

The LG 34UC89G monitor with a 34-inch ultra-wide panel has a resolution of 2560 × 1080, a response time of 5 ms and a refresh rate of 144Hz with an overclock to 166 Hz. Nvidia G-Sync is supported by this monitor. Guided by gamers, this new monitor costs $900, which is a very high price for a Full HD screen, even with all the features in mind.

Monitor design

The LG 34UC89G design differs little from LG's home and office monitors, except for the color - matte and glossy black with red elements instead of grayish-silver.

The company has just switched to the colors that were adopted for gaming devices a few years ago and have already bothered everyone. The design has more plastic than metal - this applies to the rack. But, the 34UC89G will not crack, even if it is pressed or pushed against it, though it staggers. The instability and materials of the case are grieving, especially given their high price.

The slope and height are adjustable here, as on other ultra-wide high-end monitors, and the VESA mount allows you to select another rack.

Connectors and Ports

Usually there are a lot of connectors on ultra-wide monitors, however, LG 34UC89G has only one DisplayPort, one HDMI input, a 3.5 mm audio output and two USB 3.0 ports.

A USB Type-C connector or a USB hub with 4 connectors is missing, which is also distressing.

Menu and Settings

To control the panel, use the joystick, which is located in the middle, under the screen. The joystick moves in four directions and can be pressed like a button - it's better than the touch keys with slow response, in some of the competitor models.

The LG 34UC89G menu follows a gamer style and is painted in red and black tones. In the main window, there are several large status indicators, allowing you to quickly be acquainted with information about the current input, resolution and refresh rate.

At the bottom of the menu, you will find a wide selection of options and modes for the screen. For example, the modes for first-person shooters and strategies, differ in response time and scale. In the menu, you can also select acceleration, which increases the refresh rate from 144 to 166 Hz, and the crosshair function, which simplifies the aiming in games.

In the submenu of the 34UC89G, the usual parameters are adjusted: brightness, contrast, gamma and color temperature. The temperature changes between "warm" or "cold", but not according to Kelvin. With an accurate adjustment of the color palette helps separate RGB-slider.

In a separate tab, you can select the language, adjust the LED indicator, set the standby mode and turn on the quick recharge function.

Image quality

In addition to subjective impressions, I used Datacolor Spyder5Elite to accurately measure the screen performance. With a contrast ratio of 920: 1, the LG 34UC89G is second only to the Acer Predator Z35. The maximum brightness is 330 nits, which is more than enough for a desktop display.

Gamma 2.3 is above the ideal 2.2, so the images seem a bit darker than they should be. It covers 100% of the spectrum of sRGB and 80% of AdobeRGB. Approximately the same indicators for most high-quality panels, the aspect ratio is 21: 9.

The accuracy of the colors of the LG 34UC89G is 1.94, in the Acer Z35 - 2.45, Samsung CF791 - 2.56, LG 34UC98 - 0.95. The closer the score to 1, the better.

Deep contrast and harsh colors provide high realism in games and films. However, because the 2560 × 1080 resolution is "stretched" on a 34-inch screen, the image density is only 82 ppi. Games with many small elements, for example, RPGs, seem dim.

Low resolution is justified by the high refresh rate - 144 frames per second. In the 3440x1440 format, the image density would be 110 ppi, which is better - but very few computers will pull this resolution and 144 fps at the same time.

Not always the frame rate is more important than a clear picture - the Samsung CF791 looks incredible, although it only has 100 Hz. From the user's preferences, it depends on whether the decision was to cut the quality for the sake of the refresh rate.


The Spyder5Elite calibrator will help you improve the image, changing the gamma 2.3 to an ideal 2.2. Color rendering error is reduced from 1.94 to 1.28, very significantly.

The conclusion of this review

LG 34UC89G is a step in the right direction for ultra-wide monitors. However, it costs a staggering $900, which is too expensive, given all the shortcomings.

The 34UC89G monitor will be able to work for several years, its speed will be impressive for a long time, but games and streaming services already support the formats 1440p and 4K.
