Great quality for the price!
I was scouring online looking for a decent 1440p 144Hz monitor but didn't want to spend a small fortune. I came across these and decided why not bite the bullet and try them, to my surprise they're actually really nice quality and very solid. Only gripe I have is that the stands are the best and could be more sturdy. Overall an extremely solid monitor if you want 144hz 1440p monitors for a great price!

bad quality control
I bought two for my computer. Then 4 more for others i work with. At first they seemed ok, but now we are all dealing with issues with them needing to be turned off and on or unplugged to reset the connection to get them on. I can only expect overtime it will get worse until they all finally break completely.
The picture isnt great but i wasnt expecting it to be at this price.
Ive tried other cables, refress rates, resolutions ect...

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.
