I've got a 2015 15" Macbook pro, 2.5 GHz, i7. (With the right adapter), can I run two LG UltraFine 24MD4KL 24" at 60 hz? I'm a bit confused about the specifications found here: https://support.apple.com/kb/sp719?locale=en_US

Under the graphics sections, I found the following:

Does this mean that I can only run one of the monitors at 60 hz and the other one at 30 hz?

No. You can run two 3840×2160 monitors at 60 Hz via DisplayPort 1.2/Thunderbolt 2. I have a 2013 15" MacBook Pro with the Iris Pro, and have done it. You need two Apple Thunderbolt 2 to Thunderbolt 3 adapters and two Thunderbolt 1/2 cables, one for each monitor. (You cannot daisy-chain the second monitor to the first.)

Will it matter if the cables are thunderbolt 1 or 2?
