Before you start smashing holes through drywall and turning your home theater upside down, you might want to take a look at this Gefen wireless HDMI extender, sending 720p or 1080i video up to 33 feet away and perhaps saving your marriage. This box looks a little different from the one we saw at CES last January, and uses a wider frequency band, 3.1 to 4.8GHz compared with that 3.3 to 3.5GHz band we witnessed at CES.
You need two boxes to get 'er done, and that receiver looks a bit cumbersome to mount atop a projector. Also, this unit is HDMI v1.28-compliant, not the latest v1.3, and it can't do that coveted 1080p resolution, which Gefen told us it was working on back in January. That capability might take a while longer to develop, because 1080p is one huge bandwidth hog.
Meanwhile, this Gefen unit is not actually even available yet—it's a pre-order, and to put your name on the list it'll cost you a cool $600.
