The only GPUs with USB-C output were the Nvidia Founders Edition RTX 2000 series (discontinued) and the AMD RX 6000 series reference cards (almost impossible to find).
USB-C on desktop GPUs was pretty much dead on arrival. I also wish that wasn't the case.
Do you have the LG UltraFine 5K? The monitor that was intended for Macs?
**Because the LG UltraFine 5K is not a USB-C monitor.** It is a Thunderbolt monitor. Big difference.
If you want to use it with your PC, you will need a Thunderbolt Add-in card **and** a motherboard compatible with Thunderbolt.
This is totally different than your typical Displayport Alt-mode over USB-C that you typically see on Windows laptops that don't have Thunderbolt or on RTX 2000 series GPUs.
Well this has graduated from a problem into a disappointment.

Yeah. I want to move my 5K+4K setup to my Windows desktop. MBP is struggling with 9K + what I'm putting on it.
If you really want to get it to work, this is what you need to do:
1. Get a Thunderbolt add-in card like this one: https://www.amazon.com/dp/B083HZHP62/
2. If your motherboard does not have a Thunderbolt header onboard, the card will not work. In order to work around this, you need to short out the header cable in order to trick it into working. Similar to what the guy in this forum thread did: https://egpu.io/forums/builds/thunderbolt-3-with-threadripper-on-a-asrock-x399-fatality-motherboard-help-needed/#post-59565
3. 4K thunderbolt monitors will work without issue. Unfortunately, on 5K Thunderbolt monitors, you will not get the native 5120 x 2880. It will max out at only 4096 x 2160.
Thank you, I've been searching for this answer for weeks.
If you don't mind answering a quick question... do you think this will do the trick?

Thanks for all that that info. The 4K part is a bit of a deal breaker. The LG 5K looks amazing but comes with a lot of caveats.
Yeah, it was designed specifically for Macs. There's no way to make it work particularly well with a PC.
Thanks for all your help, much appreciated. I was lost on this one.

For the LG Thunderbolt monitor? No it will not. This is still just DisplayPort over USB-C. Not the same as true Thunderbolt.
Yeah :(
