For those curious (sorry if someone has already mentioned), but I tried connecting my Studio Display to my work Windows PC laptop, which is a Lenovo X1 Yoga, and it works almost perfectly.
Charges the laptop.
Webcam works fine with the Microsoft default driver, and is picked up as supporting 1080/30fps. Looks fine.
Speakers work fine including volume control (although Windows shows a driver error)
Screen looks great in Windows 10, but it refuses to let me use the maximum resolution of 5120x2880. I can only choose 3840x2160 in both clamshell and extended desktop. This could just be a driver issue though, and it looks fine at this resolution.
Devices connected to the USB-C ports on the display work just fine.
I'm really happy with this monitor. It was important to me to be able to use it with my M1 MBP, and my Windows PC laptop. The early reports suggested that it would be a compromise at best using it with a PC, but thats just not true in my experience so far.
