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.

“my gasoline dollars” would have been more accurate.

There are a few: https://en.m.wikipedia.org/wiki/List_of_large_language_models

You can run some of them on your computer and do anything with them.

Others - Grok in particular - don’t have safeguards. And even if they have safeguards, depending on how they were implemented, you may be able to circumvent them.
