LG 34UC80 Front

For those looking for a large curved UltraWide display that is not too costly, you will probably run across the LG 34UC80. With it’s appealing features, including the 21:9 curved 34-inch display, AMD FreeSync, and impressive USB 3.0 quick charge, you might not want to wait much long to get your hands on this one.

Its affordable price (when compared to other 34″ curved monitors) is one of the top selling points, and brings you the luxury of enjoying an incredible screen without it costing as much as your PC. Many other manufacturers charge well over $1000 for a display of this type, so kudos to LG for bringing this technology to the rest of us and not charging an arm and a leg for it.

Image Quality

The LG 34UC80 is a 34-inch 21:9 Ultra HD IPS monitor with a sRGB of over 99%. The screen resolution has an Ultra Wide Quad Definition of 3840×1440.

The IPS panel has a color depth of up to 10 bits (8 bit+FRC) making 1.07 billion colors, and a brightness of 300 cd/m2 (candelas per meter squared), giving the screen a vibrant and sharp image in all lighting.

It’s clear LG is aiming this monitor at anyone wanting in on the curved display trend. They state on their website:

The 3440 X 1440 UltraWide QHD display offers amazingly sharp picture quality¹. Its pixel area is about 1.8 times larger than an UltraWide Full HD 21:9 monitor, and about 2.4 times larger than a Full HD 16:9 monitor. It provides an efficient environment in using Microsoft Office programs showing 47 columns and 63 rows in excel. With over 99% coverage of the sRGB spectrum this LG monitor is a great solution for professional photographers, graphic designers or anyone looking for highly accurate color.

The high-quality sRGB of above 99% will give you beautiful and accurate colors, especially for professional photographers and video-editors who need accurate colors to make sure what they are creating looks the same on every type of screen. However, if artists and content creators tend to prefer flat panels, gamers usually prefer curved monitors since they are much more immerse. It’s nice to see LG bringing an designer-grade display to the gaming market.

Gaming Performance

The monitor features the AMD FreeSync technology with a FreeSync dynamic range of 48-75 Hz, providing you with an incredible gaming experience by eliminating issues like screen tearing, motion blurs and pixel transition delays.

Even through FreeSync can enable the frame-rate to fluctuate up to 75Hz, the native refresh-rate is a maximum of 60Hz.

LG confirmed this monitor has an input lag time of 5ms GTG, which should be adequate for most gamers since the refresh rate is limited to 75Hz. At 75Hz, a 5ms input lag means there is less than one frame lag, so you can be sure you wont be at any disadvantage when playing fast paced games.

One major gaming feature that comes with the LG 34UC80 is the inclusion of all the latest game mode features. There are 3 gaming modes on the 34UC80; 2 First-Person-Shooter modes and and a RTS (real time strategy) pre-set mode so you can choose the best mode for the game you are playing.

Standout Features / Design

You will find the USB 3.0 quick charge to be an amazing add-on feature. Now you can comfortably charge your cell phones, laptops and tablets at a faster and more efficient pace, while working at the same time.

The monitor contains two HDMI 2.0 cable ports, doubling the media inputs from many monitors. You can easily switch between inputs from the joystick on the bottom of the monitor.

What’s more is that the height and tilt-adjustable stand offers a hassle-free way for inserting the screen to the stand – a simple press-and-click method to lock it into place.

The LG-34UC80-B weighs 8.3 lbs, with a dimensions of 32.2×17.6×9.9 (WxHxD) without stand and 32.2×17.6×9.9 (WxHxD) with stand.

At a quite reasonable price, you might not want to miss out on the opportunity of purchasing the LG 34U380 monitor. Other products with almost comparable features would charge more than what LG is selling it for.

USB charge 3.0 is a unique feature that is not yet offered in many monitors.

This large monitor might, however, be limited in some areas. For example the low refresh rate or lack of HDR may turn some buyers away, but make no mistake for this price it’s hard to find a better gaming monitor.

In all, we would absolutely recommend this monitor to anyone looking for an immersive curved gaming display. Sure, there are faster frame-rate monitors out there, even sold by LG, but this 34U380 is a great monitor for those wanting among the best 60Hz gaming monitors you can buy.
