Questions about this item

Will the BTB connector on the 4XH1K25074 card need replacement after repeated insertions?

The BTB connector is a factory-integration component designed for permanent installation inside the ThinkCentre Tiny chassis; no routine replacement is required.

What limits sustained HDMI 2.0 output on the 25074 expansion card?

Sustained HDMI 2.0 output is limited by the host system's graphics capability and thermal budget, not by the expansion card itself.
