Much of the R&D effort for Panasonic’s TVs gets funneled into plasma technology — with excellent results. (Check out the TC-P55VT30 in our Editors’ Choice Awards here.) But as we found out this time last year upon reviewing the company’s TC-L42D2, it also makes sets of the LCD persuasion. Quite a few of them, in fact.

It’s that time of year again when the undead walk the earth. But along with ghosts, vampires, and zombies, another partially animated entity haunts us: Blu-ray players in need of a firmware update.

As an A/V connection standard, HDMI has its downsides: limited cable length, glitches, slow switching, and version upgrades that make new gear incompatible with old stuff — the list goes on. But a major upside is that one interconnect can handle the jobs previously carried out by a thick wad of cables. In its most current version, HDMI 1.4, a single link will convey high-def video/multichannel audio, link devices to a local network (HDMI Ethernet Channel), and route audio signals from a TV back out to an A/V receiver  (Audio Return Channel). Sweet!

But any TV making the hook-up also needs to be plugged into a power socket. That means an additional wire, plus the logistical problem of locating a TV near an AC outlet — or, for a wall-mounted installation, of embedding one within the wall (a task that generally requires the services of an electrician). Wouldn’t it be great if HDMI also carried power?

HDMI can’t. But HDBaseT can.

While 3D movies haven’t totally taken over the multiplex, the format remains a force to be reckoned with. Michael Bay just released a new Transformers installment in 3D (Transformers: Dark of the Moon), James Cameron is at work on Avatar sequels, and the entire Star Wars saga is being formatted for 3D release.
