Don’t let me get you down — LG’s 5K display might work just fine for your setup. But it doesn’t seem like an adequate replacement for the Thunderbolt Display. It doesn’t have the same hardware quality as an Apple product, it doesn’t have comparable functionality, and it has an ugly “forehead” to house the camera. Unfortunately, it seems like Apple won’t make a true successor to the Thunderbolt Display because they’re not making displays any longer. For a niche of Mac users, that’s a big loss.
I haven’t purchased a standalone display since I stopped using PCs in 2006. Every display I use is now built into the machine it’s connected to. And although I’m unsure I’ll ever be in the market for a standalone display again, if I was to need such a product, I don’t even know where I’d begin. I always assumed that I could just buy the one Apple makes, but that’s no longer the case. And that stinks.
