Given the 34" LG monitor I'd been eyeing off was entirely unavailable everywhere, I'd decided to just stick with my iMac-in-Target-Display-Mode setup for when the new MacBook Pro arrives. Unfortunately it turns out that the iMacs with Thunderbolt DO NOT work in TDP with M1 Macs. 😞 So I'd be without a proper desk setup. On a lark over the weekend I decided to check for that monitor again, and lo and behold it was in stock! Ordered one and it just arrived. 🎉
I can't actually USE it until the new MacBook Pro arrives though, because I don't have remotely enough space on my desk for my old iMac plus the new display. 😛
