I've noticed that there's quite a few threads on this forum regarding whether various older MacBook Pros work with different combinations of the LG UltraFine 4Ks. I wanted to add my success story: I have a late 2013 model (MacBookPro11,3 with GeForce GT 750M) and I can confirm that it does indeed work with dual 4K UltraFine displays. The displays are driven at the full 4K resolution at 60Hz. My setup is as follows:
- Late 2013 MacBook Pro w/ GeForce GT 750M
- 2x LG UltraFine 4K 23.7" (the newer, 2019 model)
- 2x Apple Thunderbolt 3 (USB-C) to Thunderbolt 2 adapter
- 2x Thunderbolt 2 cable (1x 0.5m length, 1x 2m length)
