Is there a better alternative?

If you’re looking for a monitor that’s only for gaming and absolute (color) performance isn’t as critical, the AOC CU34G2X with its VA panel gets you most of the way towards the LG’s experience. However, its build quality is lower, color accuracy is not as impressive out of the box, and its motion clarity is significantly worse.

　　LG’s 34CB99 offers a Nano-IPS panel and format with great colors for editing at two thirds the price, but lacks the high-refresh rate gaming prowess the 34GN850 has. It’s a good choice if gaming is not important to you, or you only play slow-paced games (like Civilization VI or Microsoft Flight Simulator).

　　The only monitor that has similar performance in gaming and productivity is the Alienware AW3420DW, which has a nicer casing and stand, but doesn’t match the LG for performance, and has a notably higher price tag.

　　

How long will it last?

The monitor itself should last as long as any monitor does: a minimum of 5 years, though LG will only cover it with a warranty for the first year.

　　It’s possible that the monitor’s IPS panel will seem out of date soon, as OLED is much better. On the other hand, OLED has existed for some time now, and monitors have still not adopted it because of issues with price, availability, and image retention. It’s possible IPS technology will remain relevant for years to come.

　　

Should I buy it?

Yes. Right now, there just isn’t a better alternative when you want an ultrawide that’s good for both work and play. Just note that LG can’t seem to keep up with demand, so getting your hands on the LG 34GN850 might to be a bigger challenge than you would think, and you may need to pay up to $100 over MSRP.
