I think there's an interesting article I read on the LG UltraFine 5K Display from Anandtech http://www.anandtech.com/show/10798/lg-introduces-new-4k-and-5k-ultrafine-monitors - reproducing it verbatim, it says:
"While I'm on the topic of Windows support, I will say that from a technical perspective, the displays should work with a Windows computer. However, product listings for the monitor specify that you need a Mac with USB-C for the 4K model, and a Mac with Thunderbolt 3 for the 5K model. This limits the 4K model to Apple's MacBook, and the new MacBook Pros, with the 5K model only working on the latter. This also ties back to the integration with macOS. Most monitors use physical buttons for controlling brightness and volume, but the LG UltraFine displays use the integrated controls that macOS provides, meaning that it can respond to the volume and brightness keys on Mac keyboards. It doesn't look like the monitors have any buttons to fall back on, so this may be another situation where Windows users should be wary, and it definitely explains why the monitors are being marketed specifically for their integration with macOS."
That said, not sure about what else is meant by macOS integrated controls but we do have brightness buttons on the Eve V keyboard so I do hope it's possible too! And forgive me if there's anything I got wrong, I am no IT expert
