No, not to hook up external components. I have the cables from those that I was already using, I just want to make sure there is no newer, better kind of connection that I'll now be able to use with the newer TV.
It doesn't look like it, though, as the "newer" connections now are not ones that my DVD player and whatnot were designed to use anyway.
Looks like I'll have plenty of HDMI options though if/when I upgrade to Blu-ray or decide to add something else. (By which time HDMI will have become old news, lol, if it isn't already.)
