5 HDTV accessories to have

	Belkin PureAV HDMI-to-DVI cable When to use it: The latest set-top boxes, upscaling DVD players, and HDTVs use an all-digital HDMI connection for video hookups. Slightly older models are equipped with DVI jacks--HDMI's bigger, older brother. Belkin's handy converter cable--it has an HDMI plug on one end and one for DVI on the other--bridges the divide, allowing you to connect an HDMI source to a DVI display, or vice-versa.
	Monster Cable HDMI-DVI adapter When to use it: Your cable company set you up with a bleeding-edge set-top box equipped with an HDMI port, and it even included a matching cable. But your HDTV--only 18 months old--sports an older DVI connector. Don't fret: you can easily convert your DVI jack to an HDMI version by affixing this handy Monster Cable dongle.
	Belkin PureAV DVI dual-link cable When to use it: Unlike the mix-and-match scenarios above, anyone with an all-DVI setup--an HDTV monitor and an upscaling DVD player, for instance--should opt for a cable with DVI connections at both ends. These versatile cables will also work with the increasing number of DVI-equipped PC video cards and monitors.
	Gefen DVI HDTV switcher (EXT-HDTV-241) When to use it: DVI is a tad older than HDMI, but when it comes to A/V receivers, it's just as scarce. If you need to switch between multiple DVI-enabled devices, Gefen's HDTV switcher will get the job done.
	Zenith ZHDTV1 Silver Sensor indoor antenna When to use it: If you're unable to do an outdoor antenna installation (in an apartment, for instance), opt for an indoor model instead. The ZHDTV1 Silver Sensor is an affordable and retro-stylish way to pull in those digital signals without bolting something to the roof. This indoor antenna offers a no-fuss connection to your HD tuner, whether you have an integrated HDTV or a separate set-top box.
