This monitor is really great and it also came in time.

Fantastic Sale Price

Just took delivery of this from a 24 hour sale discount of $250! The ergonomic stand is very sturdy and just seems to move exactly where I want it. Display is excellent. At full price it would probably be more than I need but I love the B& H sales.

Great picture quality, love the arm and all of its features.

Excellent picture quality for the price. Seem less neutral with windows but slightly over saturated with my M2 pro mac mini. I'm using Ventura. light weight at 15lbs and with the arm goes to over 23lbs. Meaning the arm weighs in over 8lbs by its self. Soon to use dual display software directly from LG.com, you will really like this monitor and can be found 100 dollars off, like the way I got mine when its on sale.

Great for multitasking

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

[This review was collected as part of a promotion.] 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.

[This review was collected as part of a promotion.] 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 had been eyeing various ultrawide monitors for my home office. This one came up on a special sale and I grabbed one. It is excellent, good brightness and excellent package. It is nice to see an affordable monitor from LG. The resolution is excellent for my needs as an amateur photographer as well. It works well for my IT work and the fact I can share with 2 different systems is a huge win. The onscreen control software is excellent. the mounting system is perfect as it is easily adjust for height and angles, include various ways to mount to the desktop while leaving plenty of space on my desk. I love no extra mounts to have to go and purchase.
