Active Silicon AS-PHX-D20-PE4H HDSDI x4 PCIe card in a Sonnet "Echo Express III-R Rackmount Thunderbolt 2 Expansion Chassis" (or any Sonnet TB2 chassis) is the best choice..
Magma and other TB2 chassis also work
(I would avoid all blackmagic products)

The Sonnet Mobile Racks are expensive and also require an SATA PCIe card
