I appreciated this post because I bought an Apple Studio Display to replace my LG 5K UltraFine that I should get in a few weeks (VESA option took longer to ship) and I was curious how much easier/harder it would be when using Windows. I'm primarily a Mac user but like the author, would like to use my external monitor with all of my devices if possible.

I built an AMD gaming rig last year with a motherboard with a TB3 port built-in (one of the few AMD options to support this) but because of how it is configured (there is only one DP-in port on the motherboard and you need two of them over DP 1.2 to get a 5K signal), the LG 5K only outputs at 4K. All things considered, that was a fine trade-off.

But it looks like the new display is DP 1.4 (at least in theory), meaning I can at the very least use the adaptor cable to just get 5K signal, even if speakers and webcam don't work.

I wish all of this were easier and that Thunderbolt were easier, because it's such a great technology and it is frustrating we have so few options.

I actually did the exact same thing. Went with the ProArt B550 and didn’t consider that the LG 5k requires two video connections to the graphics card. This[0] eventually helped me realize my mistake. Currently running in 4k and it’s fine. At least camera, speakers, and hub work.

Good to know even the ProArt B550 has the same issue (I have the B550 Vision D-P) because I was half-considering swapping for the ProArt B550 (which would ruin the white aesthetic I'm going for, but fine), but if it doesn’t have two DP inputs, that’s a no go. It’s possible the DP 1.4 on the Studio Display would be enough to provide bandwidth on the TB4 connector, but I'll have to wait for others to try it first in the hackintosh forums or elsewhere.

A quick look through Newegg shows 4 AMD AM4 motherboards (B550 and X570) with Thunderbolt (2 TB3, 2 TB4). None have two DP inputs. I didn't see any Intel (LG1200) with two inputs either.

Would you use a Maple Ridge (TB4) card instead of Titan Ridge?

I am impressed with Apple's ability to seamlessly handle all of these scenarios. Their product integration really does create a great experience within their ecosystem. I didn't expect my setup to work perfectly but I'm happy it gets most of the way there. I'm not pulling the trigger on Apple Studio Display but I'll be watching progress to see if it works.

My use case is an outlier, I guess: I'm in the Apple ecosystem for all personal stuff but use a Dell Latitude for work (TB3, GPU chokes on 5k but technically works) and have a beefy Windows desktop for gaming and personal development work in WSL. I love the idea of just plugging a single cable into whatever system I'm using at that moment.
