I remember the controversy around the 27" Apple Thunderbolt display: it doesn't work with a PC. Despite the fact that Thunderbolt encapsulates DisplayPort, you cannot use it with a DisplayPort connection - which is even more confusing considering Thunderbolt 1 and 2 use Mini-DisplayPort physical connectors.
The new LG Ultrafine 5K display looks very attractive - at least as far as the published specs are concerned (I'm not a fan of the 'chin' on the top of the monitor). I see that it only connects using USB-C connectors and according to Apple's published information: it uses Thunderbolt 3 over USB-C to deliver a 5K video stream by using both DP1.2 channels at once.
...but does this work with a PC? And if so, to what extent?
My current workstation has a Broadwell-E X99 motherboard which has an ASUS Thunderbolt 3 add-in card which "works" by having me connect a DisplayPort cable from my GPU's output back into the Thunderbolt card, which then combines it with the PCI-Express channels. My GPU is an NVIDIA GeForce GTX 1080 which supports DisplayPort 1.4 - I note that only DisplayPort 1.3 is necessary for uncompressed 5K at 60Hz in 24-bit color mode - but Thunderbolt 3 only supports DisplayPort 1.2 - and I can't see any other Thunderbolt add-in cards that accept two DisplayPort inputs (for dual-channel DisplayPort)
- Can the LG Ultrafine 5K monitor be used with a PC - in any capacity?
- Can the LG Ultrafine 5K monitor be used with a PC - in 5K 60Hz mode using a computer with DisplayPort 1.4 ports?
- Is there also enough bandwidth to run it in 5K/60Hz mode with a Gigabit (or even 10GigE?) adapter also plugged into the monitor?
- As an aside, does the monitor support multiple inputs? What if I attach another Thunderbolt 3 video source to another of the USB-C ports on the monitor?
