PostPoints tip: Label an HDTV's inputs

The back of a high-definition television can look like a high-tech pincushion, between all the different video inputs provided: HDMI, component, VGA, S-Video and composite. Things can be just as confusing on the front of the set if you have to remember if "HDMI1" is your cable box or the DVD player before switching input sources with the remote. But some high-def sets allow you to assign labels to each input, changing "HDMI1" to "CABLE," "HDMI2" to "DVD," and so on. Dust off your TV's manual to see if it allows that function; if it does, spend a few minutes labeling your inputs, a task usually started by hitting the remote's "menu" button and then diving into the TV's "setup," "options" or "preferences" screens. Better yet, if you're staying with less-technically-adept friends or family members who haven't taken this step with their own HDTV, offer to do it for them. Either way, you can save yourself tech-support time later on.
