lg 34uc80-b review


The LG 34UC80-B is a gorgeous 34-inch curved ultra-wide monitor that’s great for gaming, watching movies, productivity, and even color-critical work.

The best part?

For the image quality and performance it offers, it’s very appealingly priced and you get tons of exclusive features, too!

Image Quality

The LG 34UC80-B monitor is based on LG’s own AH-IPS panel with 10-bit color depth support via dithering (8-bit + FRC). It’s factory-calibrated to cover over 99% of the sRGB color gamut which makes it a great monitor for photo editing and other similar color-critical tasks.

Besides ensuring perfect color accuracy and consistency, the panel delivers wide 178° viewing angles so that colors won’t shift when viewed from skewed angles, a quick 5ms response time speed which eliminates ghosting of fast-moving objects, a decent 300-nit peak brightness, and finally, a standard 1,000:1 contrast ratio.

On the 34-inch screen of the LG 34UC80-B, the UWQHD resolution of 3440×1440 pixels and 21:9 aspect ratio results in a rich pixel density of roughly 110 PPI (Pixels Per Inch). This is the sweet spot between screen real estate and picture detail meaning that you will have both plenty of workspace as well as sharp and vivid details.

As movies are natively shot at the 21:9 aspect ratio, you will be able to enjoy your favorite shows and movies on the monitor. While a lot of games support 21:9 natively too, you will have to settle for black bars at the sides or a stretched image in certain games. You check out all the games that support 21:9 here.


Straight out of the box, the LG 34UC80-B IPS display provides an outstanding image quality. We haven’t run into any dead pixels while the backlight bleeding and IPS glow was minimal.

AMD graphics card users can use compatible graphics cards to synchronize the GPU’s frame rate with the LG 34UC80-B refresh rate and thus eliminate screen tearing and stuttering within the 48-75Hz FreeSync range using the DisplayPort connector.

Nvidia users can also use the monitor at 75Hz by creating a custom resolution, but won’t be able to benefit from the variable refresh rate technology, naturally. At 75Hz, gameplay is noticeably smoother and with the Dynamic Action Sync feature enabled we’ve measured input lag to be only ~10ms.

Out of all the similarly priced 1440p ultrawide monitors, the LG 34UC80-B offers the best response time speed i.e. pixel transition time. Motion blur and ghosting are barely visible in fast-paced games; additionally, you can use the Response Time Control feature in the OSD (On-Screen Display) to further eliminate ghosting.

We’ve found that the fast-paced gameplay looked much better on the LG 34UC80-B at 75Hz than it did at 100Hz on certain VA-panel 3440×1440 ultra-wide monitors such as the Viotek GN34C as there was considerably less motion blur. However, the 100Hz refresh rate does offer noticeably more fluid and smooth feel to fast-paced gaming.

The OSD is navigatable using the joystick that’s placed beneath the bottom bezel of the monitor or you can use the On-Screen Display application and adjust all settings in a desktop application instead.

In addition, you will be able to find the Screen Split feature which consists of numerous different layouts for easier multitasking by letting you snap an application window to a certain part of the screen. There are also PiP (Picture in Picture) and PbP (Picture by Picture) modes available.

Besides the common adjustments such as contrast, gamma, brightness, color temperature, etc, there are advanced 6-axis color settings available as well as the Reader mode which enables the blue light filter for a more pleasant viewing experience at night.

For gaming, there’s the Black Stabilizer feature which alters the gamma curvature in order to brighten up objects in dark areas of games. Furthermore, you can customize your own gaming presets with optimal picture settings or simply use the pre-calibrated RTS or one of the two FPS modes.

Design & Connectivity

The design of the LG 34UC80-B ultrawide monitor is simple and sleek. Ergonomics include -5°/20° tilt, up to 120mm height adjustment, and 100 x 100 holes for VESA mount. The monitor curvature is 1900R which is perfect for immersion.

When it comes to connectivity, there are two HDMI 2.0 ports, a DisplayPort 1.2, the headphones jack, and two USB 3.0 ports. The USB 1 supports fast charging as well though you will have to enable it in the OSD first. When fast charging is enabled you cannot transfer data to or from the connected device.

Price & Similar Monitors

lg 34uc80-b vs dell u3417w

Dell U3417W

The LG 34UC80-B price amounts to $550 at the moment (March 2018) which is a great deal considering the specs.

The LG 34UC80 model is also available with 2x7W integrated speakers as the LG 34UC88-B but it’s more expensive. The same monitor is also available with the Thunderbolt 3 connectivity, the LG 34UC98-W.

Another popular 3440×1440 IPS monitor is the Dell U3417W which uses the same LG panel that’s in all of the above-mentioned monitors. While it may have a better-looking design, it’s also more expensive yet the image quality and performance are virtually identical.

Alternatively, if you’re mainly into competitive FPS gaming and want an affordable ultra-wide display, you should check out the LG 34UC79G, an IPS monitor with a 144Hz refresh rate but a lower 2560×1080 resolution. Another great monitor is the mentioned Viotek GN34C we’ve reviewed with a 3440×1440 VA panel and a 100Hz refresh rate; all under 550 USD.

In the end, the LG 34UC80 is the best deal by far when it comes to price/value.


If you’re looking for a monitor which excels at pretty much everything albeit competitive FPS gaming, the LG 34UC80-B won’t disappoint you. Overall, it’s the best 34-inch 3440×1440 IPS curved ultra-wide monitor for the money. The sleek design and the plethora of features including AMD FreeSync and 75Hz refresh rate are a big bonus.
