I bought this monitor for my office. The setup was extremely easy, and the display is sharp! The adjustment was super easy. By the way, I used the DisplayPort for the best result.

I am a web developer and this is by far the best addition possible to my workstation. The stand is sturdy and can take many positions.

I had dual 27″ monitors for years. I upgrade one to 4k — and that was nice. But the reality was that the two monitors always had a gap between them and were at slightly different angles and I never really used them as a single sauce. Moving to the 34″ single monitor had multiple beneficial effects. (1) The single larger continuous space is much more adaptable to my needs to have open multiple concurrent apps and files. It is all right in front of me in a single uninterrupted plane. (2) Unexpected benefit — my entire desk setup feels more open, uncrowded, more comfortable. Definite win-win. Although the monitor isn’t 4k I find the resolution to be completely clear and more than sufficient for my purposes which involve text far more than images. Definitely and whole-heartedly recommended.

Overall picture quality is amazing for such a wide screen. Setup was very easy. The mounting bracket provides A LOT of extra deck space. My only dislike I have regardining monitor is that you can not adjust volume through your computer or connect device.

I really wanted to love this monitor. The size was great and quality what you would expect from LG. Resolution wasn’t there for my needs (graphic design and photoshop) so I had to look into a 4k/5k resolution option. Great for general office use and the ergo arm is fantastic.

I have been using this LG 34WN780-B UltraWide Ergo 34″ monitor for a few weeks now and it is a fantastic upgrade over my old 27″ monitor. The Ultrawide 34″ monitor offers so much more work space over the old 27″. The higher resolution and the wider format allows me to view several documents or emails at once. I can have several windows side by side so I can work/view multiple things without having to flip thru windows. It makes my work flow much faster. It’s always better to work smarter, not harder. I use the monitor in a home office, so I appreciate the multiple inputs. There are two HDMI ports and a display port. I have my PC hooked up via display port and then a couple game consoles via the HDMI. I’ve done quite a bit of gaming and movie watching on this monitor now as well. The colors are fantastic as is the response time. Having HDR10 at the price point is also great. The HDR10 looked great in my movie playback. Setup was also very straight forward. The monitor was easy to mount. All my components also plugged right in and I had zero configuration problems setting my PC and equipment up. If you are looking for a wide screen monitor, I would definitely recommend this LG 34WN780-B UltraWide Ergo 34″ monitor. It was easy to setup, looks fantastic, and displays everything I throw at it. I received this product at a discounted price for my fair and honest review.

As a software developer I have multiple programs and windows open. Having the ultrawide is perfect for multitasking and splitting up the screen!

As a person with vision disabilities this monitor makes my daily life much easier. Depending my vision on a particular day and the lighting in my office at the moment a stationary monitor makes it difficult for me to adjust the screen to properly see the screen and it’s content. With the ego arm I can now adjust my view to my particular need at that moment. It a Godsend!
