Hm, I bought this cable today, so I'd think it should be ok --- but I
didn't explicitly specify that it must be one that does 4k@60.  I didn't
know I might have to.

Is there any way to tell?  The sticker on the package only says DP/DP
2.0m.

Unfortunately, the cable that came with it has a normal size connector
on one end and a small size connector on the other.  Both the monitor
and the graphics card require the normal size connector, so I cannot use
that cable.  That's why I bought one ...

Np; when I don't have the right cable, it'll never work anyway.  Now I
know what I need to look into first :)
