Is this display compatible with the previous generation of Retina MacBook Pros?

As far as I can tell, it is not. I have a mid-2015 15" macbook pro with retina display, 2.8 GHz Inte As far as I can tell, it is not. I have a mid-2015 15" macbook pro with retina display, 2.8 GHz Intel Core i7 processor, 16 gb of ram and Intel Iris Pro 1536 MB graphics card. I've tried it with TB 3 to TB 2 convertor and an HDMI cable, a USB-C to mini DisplayPort convertor and mini DisplayPort cable, and USB-C to 4k HDMI convertor with HDMI cable / port as well, all with no luck. The mac does connect to an old TV using the HDMI cord, so I don't think it's an issue with the mac. The plan from here is to call LG support and find out if there's ANYTHING I can do that will allow me to use the monitor with the mac. Otherwise, I sure hope they'll take it back at apple, since my company bought it and I've already discarded the box. I'll update this answer if I find any combination that works.
