If I don't watch movies or play games, but the PC may be used to do some web-designing (not animations though), would HDMI help at all? Currently PC is using VGA.
It's more of a theory/hypothetical question, so please don't reply like "HDMI doesn't cost much" or "it's going to be outdated soon" or "this is better alternative to HDMI".
HDMI (and DVI-D) are digtial interfaces. They will, potentially give you a clearer picture on LCD monitors. VGA is analog, and often LCDs will render a less-than-crisp image even at their native resolution.
HDMI also has a DRM specification which may (depending on video hardware licensing) allow you to watch dvds which you might not be able to view over DVI or vga.
The connector is smaller. This enables smaller form factors and I prefer not having cables that need to be screwed in sometimes.
