What People Are Saying

Rated 5 out of 5 by from Great monitor Was deciding whether to get two monitors or one ultrawide and I have no regrets getting. 2k, IPS, adjustable height, great colors, box includes all the accessories you'll need too. Great product, cant ask for more for its price.

Rated 5 out of 5 by from So Much Better Than Multiple Monitors! Although I bought this monitor for photo shows and other graphic work, it has proven its worth in every application. Images are detailed and straight. The monitor was well packaged and easy to install. Overall, it couldn't be any better.

Rated 5 out of 5 by from Ultrawide is your new best friend. I'll keep this review short and simple for you. This monitor is glorious. You'll love it. Why? The 34" 21:9 display is AWESOME for productivity. You can have 3 Chrome windows open at once for easy comparisons or research. You can see more of your timeline in Premiere and Final Cut Pro. Or you can even have an HTML window, a CSS window, and a live preview open all at once for web development. Seriously, the screen is tremendous. 99% sRGB means colors are rich, vibrant, and accurate, and this display has minimal light bleed. The menu system is also easy to navigate. LG makes it easy to adjust the volume, change the brightness, or even turn the display off. The worst part about this monitor? It takes a while to turn on and it sometimes takes a while to read the Display Port input from my MacBook Pro. Bottom line: this monitor is an absolute yes. You'll get something big, vibrant, and beautiful, and you'll boost your productivity with bountiful amounts of screen real estate. If you're into content production, I suggest the flat panel. If you're into gaming or media consumption, getting an ultrawide with a slight curve can provide a more immersive experience. I hope this review helps!

Rated 5 out of 5 by from Excellent Display Just got it, everything is perfect. Backlight bleed is not a problem and no different than any other monitor I've had. Sounds like this is improved over previous models but I have not compared.
