Excellent Ultrawide Monitor for a MacBook Air Setup
I purchased the LG 34U60ZB-B to use primarily with my MacBook Air, and it has exceeded my expectations. Setup was incredibly simple using a USB-C to DisplayPort cable, and the monitor was recognized immediately at its full 3440 x 1440 resolution.
The extra screen real estate is a game changer for productivity. I regularly have multiple documents, spreadsheets, browser windows, and email open at the same time, and the 34-inch ultrawide format makes it feel like having two monitors without the distracting bezel in the middle. Everything is sharp, crisp, and easy to read.
The picture quality is excellent. Colors look vibrant and accurate, text is clear, and the WQHD resolution provides plenty of workspace without making items too small. I was particularly impressed with how good text rendering looks on macOS, which is important since most of my work involves reading and writing.
The monitor feels much larger than a standard 27-inch display while still fitting comfortably on my desk. The curved screen adds to the immersive feel without being overly aggressive. It also works well for streaming videos, casual gaming, and photo viewing when I’m not working.
One thing to note is that the monitor does not provide USB-C power delivery, so MacBook users will still need their charger connected separately. That wasn’t a dealbreaker for me given the monitor’s price and performance.
Overall, this is an outstanding value. If you’re looking for an affordable ultrawide monitor for a MacBook Air or MacBook Pro, the LG 34U60ZB-B delivers excellent image quality, tons of workspace, and a clean, productive setup.

Perfect fit for my 34 inch wide monitor!
This is a really snug fit for my 34 inch wide screen monitor and provides excellent privacy from wider angles so that nobody can get a look at what they're not supposed to see. With confidential projects this is very handy to have when there are visitors around.

Not a great fit for Dell U3419W
I got this for use on one of my Dell U3419W wide screen monitors. The slide-in mount wasn't a good fit for the design of this monitor, as the bezel isn't typical and the illuminated part of the screen is a tiny bit narrower than the filter. I plan to see if I can hack something together that will work with this monitor without sticking stuff to the actual display part of the screen or leaving the filter far enough in places from the screen to make it unreadable.
I'm rating it 3 stars instead of 2 because I think I can make it work, but it seems like the attachment methods included are meant for laptops rather than standalone monitors. If I had ordered this outright, I would have returned it.
