Apologies! I meant DVI (along with a DVI->HDMI cable). But as far as I can tell, that's just as good. All digital signal and it looks crisp on my HD TV.
It's a T43/p. I believe the /p is important since the regular T43 had a crap graphics card. And I think it's a ThinkPad Port Replicator II (like $20 on ebay).
Getting the drivers for the DVI port just right under Linux took some work though.
