PC to HDTV via USB

Okay, I just used my entire quota of acronyms in the title, and I haven’t even started the entry. But this is pretty clever news. Gefen has created a “USB DVI Adapter” — oops, more acronyms — that lets you connect a computer to an HDTV. And it only uses a standard USB port. The box is powered by the port, so there’s no need for an external power source. The DVI connector lets you connect to a variety of devices, and DVI-to-HDMI cables are easy to get so you can use this box to connect just about any computer to your HDTV.

Perhaps the coolest feature is that you can connect up to six of these little boxes to one computer. (This assumes that your computer has six USB ports and sufficient processing power, though the Gefen Web site states that the device “uses little resources, ensuring a quality display without compromising performance.”) Sorry, Mac users; you’re limited to just four per machine. It supports resolutions of 1080p and even higher, such as 1920 by 1200. If there’s a drawback, it is that the box costs $149 direct from Gefen, which is a little pricey for a graphics adapter but it makes it up in convenience.
