Solid Productivity Monitor

The LG 40U990A-W 40" 5K2K ultrawide monitor is a solid upgrade from my previous Benq EX3501R 35" ultrawide. I use it with a Mac Mini M4 Pro, and the 5120 x 2160 resolution is a big improvement over the 3440 x 1440 of the Benq. I can see much more on a timeline when video editing and the screen real estate is appreciated in Illustrator, too.
The 120Hz refresh rate is easy on the eyes when scrolling in apps or scrubbing through a timeline. And when I'm writing or reviewing documentation, the 140 PPI make the text crisp enough to stare at all day, especially as I like to keep it at the full 5120 x 2160 resolution. And because there's a lot of static parts on my screen (Word or Illustrator toolbars), I think the nano IPS black screen is better for me than OLED would be, as I don't have to worry about burn-in.
I was initially hesitant to get this monitor because people complained about the noise. I had been looking at the Dell U4025QW, but because it was hard to find and only had Thunderbolt 4, I didn't go with the Dell. I'm happy to say that my LG 40U990A-W doesn't suffer from the noise. This could be because the latest firmware update was already applied to the unit I got. And the single cable Thunderbolt 5 connection from my Mac to the monitor cleans up my desk space beautifully.
Haven't gamed on it since I usually use my TV for that. However, I don't play anything that requires a super-high refresh rate, so I'm not really concerned.
All in all, I'm happy. I don't have anything negative to say. Of course, the price was hefty, but I'm looking to get many years out of it. Plus, the built-in hub means I'm saving a big chunk of change by not having to buy a stand-alone dock or hub.
I would recommend this to a friend!
