Rated 5 out of 5 by from Fantastic Monitor, great price This is by far the best value monitor I have purchased to date. I waffled quite a bit on waiting for LGs new 5k 34 inch monitor, but ended up purchasing this instead. To me, the 2k resolution of this monitor is the perfect size. I tried a 5k monitor, and was extremely disappointed, the non-native scaling is a much bigger issue than you might think. This monitor hits the sweet spot. The only thing that might make this monitor better is thunderbolt 3, but its not worth the extra cost when you can buy an elgato dock for the price difference.

Rated 5 out of 5 by from Great Monitor This monitor had pretty much everything I wanted when it comes to features and it wasn't the most current model on the market by any means. The picture is great, the setup was easy and convenient. The only thing I can complain about is the ports being fairly close to the back plate...if you're looking to mount this monitor, you'll need to coordinate on a decent mounting plate so you're able to plug in what you need to.

Rated 4 out of 5 by from Great monitor Monitor looks great my first widescreen. Only reason I went 4 stars is I could not get the speakers to work, which didn’t really matter as I wasn’t going to use them anyways but it would have been nice if they worked out if the box.

Rated 5 out of 5 by from Excellent overall monitor that is easy to use. I am very pleased with this monitor. It is very sharp looking with solid construction. I was worried that such a wide display would be wobbly but the base is well designed and supports the monitor solidly. The image is superb and colors and contrast are great! The extra width of the screen and clarity make it great for the work I do, having many documents on screen at once to compare or to watch a video or tutorial while writing. This monitor easily replaces the two 16:9 monitors I used to have and provides a more seamless workspace. Also, the built-in USB up is nice as well because I run all my peripherals through the monitor and only have to plug one USB into my laptop.

Rated 5 out of 5 by from Huge Monitor! The monitor is amazing and exceeds all expectations. I use this at work and am even more productive now that I only need one monitor instead of two. The included software to make screen setting modifications is very handy also. Highly recommend this monitor.

I cannot seam to get the monitor speakers to work on this model. I have tried using the test from the Advanced tab on the LG Ultrawide Properties dialog box, and it still does not work. I am using the HDMI input 1 on the monitor (34UC80-B).

You advertise that this monitor supports freesync but it does not!!!!! I recently purchased a 34UC80-b and while your website says you support free sync and the monitor OS has a freesync option, AMD does not list it on the website! What gives??!

Asked by: SighCy
Thank you for pointing this out. We will look into this. This monitor does support freesync. If you have any additional questions concerning your monitor please reach out to a computer specialist directly by calling 800-243-0000. ^CP

I recently purchased this monitor, however, does this monitor have build in speaker?

Asked by: phll
The speakers on my and my roommate's monitors do not work at all. So, I really doubt whether this model has a built-in speaker.
