ExtremeTech has details about 'DisplayPort,' a new proposed video interconnect standard that would be used as a catch-all solution for connecting televisions, LCDs, CRTs, and projectors to all manner of computers and home entertainment devices. That's the good part—one slim plug that should work with everything, which will even support audio. The bad part is that DisplayPort will be part of an overall 'trusted' computing platform, where media inside your computer can control your access to your own hardware.
The question is, why is this necessary? If my computer 'trusts' me enough to let me play media I have purchased (all the hang-ups of that process notwithstanding), why would I need my display to force me to another check, as well? Of course, the answer is that it's not necessary at all, but the more hurdles the hardware manufacturers put up, the more difficult it will be to circumvent copyright, should you want to do something like, say, watch a DVD in Linux.
DVI should hold us for the forseeable future. I think I'll just be sticking with that.
