Image Quality
This ultrawide curved monitor is founded on an IPS panel with 10-bit color support (8-bit + FRC for 1.07 billion colors), in fact it is factory-calibrated to cover over 99% of the sRGB color gamut thus ensuring regular and accurate color reproduction.

Other panel-related specifications add a 300-nit peak brightness, a static contrast ratio of just one 1,000:1, a 5ms response time speed, and wide 178-degree viewing angles.

LG offers three more models predicated on the same panel. We’ve reviewed the LG 34UC80, which may be the same monitor as the LG 34UC98 without the Thunderbolt 2 connectivity, which explains why it’s a whole lot cheaper.

The LG 34UC80 doesn’t have integrated speakers, though, but it’s available as a version (LG 34UC88), which has two 7W speakers similar to the LG 34UC98.

Both LG 34UC80/88 and the LG 34UC98-W curved models are also available as variants with flat screens, the LG 34UM88C, and the LG 34UM88, respectively (the 34UM88 has Thunderbolt 2 whereas the 34UM88C will not).

Overall, all five LG models provide same brilliant color quality, immersive ultrawide viewing experience, and excellent detail clarity ensured by the rich pixel density of 110 pixels per inch. So, you can choose according to your preference of the look (curved or flat screen) and whether you will need Thunderbolt 2, built-in speakers, etc.

As of this screen size, we recommend obtaining a curved model. The LG 34UC98 includes a 1900R curve, making the viewing experience more immersive and reduces distortions.


Shifting, the LG 34UC98 monitor includes a suprisingly low input lag of ~10ms, making for no noticeable delays in the middle of your commands and what gets displayed on the screen.

Further, with a reply time speed of 5ms (GtG), you can enjoy fast-paced gaming without prominent trailing or motion blur of fast-moving objects.

The monitor includes a native refresh rate of 60Hz, that you can boost to 75Hz by enabling FreeSync assuming you have a compatible GPU or by overclocking the display in the event that you don’t.

At 75Hz, you’ll notice a tiny boost in motion clarity instead of 60Hz, however the performance still won’t be practically as smooth as it’s at 144Hz, and even at 100Hz for example.

Moreover, the LG 34UC98 supports AMD FreeSync over DisplayPort with a 55-75Hz variable refresh rate (VRR) range.

Should you have a compatible graphics card, you can permit FreeSync, which synchronizes the monitor’s refresh rate to the GPU’s frame rates and so eliminates all screen tearing and stuttering within its range, which is 55FPS to 75FPS upon this monitor.

We could actually extend the VRR range to 48-75Hz via CRU, and we got FreeSync to utilize a compatible NVIDIA card without frame skipping or other visual artifacts.

Your mileage can vary greatly, though, as some users report that their LG ultrawide models (UC80, UC88, UC98, UM88, and UM88C) get tearing and/or frame skipping when working with FreeSync with NVIDIA cards.

Lastly, our LG 34UC98 unit had hardly any IPS glow and backlight bleeding under normal viewing conditions no dead or stuck pixels. Further, it includes a flicker-free backlight, so those sensitive to flicker won’t experience eye fatigue/headaches.

The LG 34UC98 ultrawide curved monitor offers a good amount of useful features, including On-Screen Control (desktop application for OSD settings), Screen Split (splits the desktop into multiple windows for easier multitasking), and Black Stabilizer (increases visibility of objects in shadows).

Other interesting features include pre-calibrated picture presets (FPS, RTS, Dark Room, Color Weakness, Cinema, Photo, and the Reader mode which applies a low-blue light filter), Picture in Picture/Picture by Picture, and advanced picture alterations such as for example 6-axis hue/saturation, gamma (four presets), color temperature, sharpness, etc.

The monitor offers Dual Controller, that allows you to hook up two PCs to the monitor, display both signals hand and hand via Picture by Picture, and use just one single set of keyboard/mouse to regulate both devices.

Design & Connectivity
As you can plainly see, connectivity options are abundant.

There are two HDMI 2.0 ports, two Thunderbolt 2 ports, an individual DisplayPort 1.2 input, a dual-USB 3.0 hub (one port with fast-charging), a headphones jack, and an audio tracks line-in jack for both 7W integrated speakers.

The look of the LG 34UC98 includes very narrow bezels and a height-adjustable (up to 110mm) stand. You may also tilt the screen by -5°/15° or mount it on a third-party stand via the 100x100mm VESA pattern.

Price & Similar Monitors
The LG 34UC98 price is normally around $800, which is very costly considering that you will get Thunderbolt 3/USB-C ultrawide monitors currently for the same price and that the same monitor without Thunderbolt 2 applies to around $550.
