Receiving $2.4 billion is nice. But not if you had to pay $1265 billion (market cap) for the privilege.

They are all realizing that this is the new reality. And the American people wanted it. So there is no good reason for them to resist.

Not sure what these internal connections are, but Displayport is both a plug and a protocol. You can use the protocol over thunderbolt and maybe other connections as well.

It depends on the displayport version. DP 1.2 only supports 4k. DP 1.4 supports more. So if it’s an older display that only supports DP 1.2, you have to use the two screens hack. I never tried that, though.
