Yes, and even if something has DisplayPort and VGA (like some Thinkpads) you'd probably want to use DP where possible.

EDIT: and I'm fairly sure the suggestion for connecting a VGA laptop to a HDMI TV doesn't actually work that way around.

Indeed -- many TVs have VGA ports, or DVA, and that should be the first option if the computer only has VGA (or DVA) out.

You can buy a VGA to HDMI adaptor, but I haven't tried one.
