There are several products on the market all touting magical abilities of getting a HDMI signal from source to a display wirelessly. And since I am in a situation where my conduit has failed me and running a new HDMI cable to my projector would involve taking the ceiling down, I figured I'd give some of these items a test and see how they do.

The first exposure I had to wireless HDMI involved the Epson 5040UBe projector which touts built in wireless HDMI. On the plus side it does work and it does get the signal from the source to the projector. On the negative side, the best it could do was 8bit 4:2:0 which was on par with my 15 year old Monoprice HDMI cable currently run through the ceiling. It would also lose connection any time someone would walk in front of the transmitter.

My second run at this was DVDO's Air 4K. This product seemed a bit more promising to me as it offered 4K resolution with a color depth of 4:2:2 at 8 bits. After testing it out for a couple of weeks, I sent it back. The problem I was experiencing with this product was, for lack of a better explanation, artifact introductions. I noticed it right away when I watched hockey from the front row of my theater. My front row is roughly 8 feet back from the screen and the artifacts while watching hockey made it unbearable to watch unless I moved back to the second row. There also seemed to be some sort of HDMI type of issue where you'd see static lines flash on the screen when I first started everything up. I never noticed it much while watching content but I'd bet it was there. Normally I'd say it was a bad HDMI cable but since the two I was using were swapped out with good, working cables, I'd say it was more of a transmission problem.

I finally broke down yesterday and purchased a 40' Ruipro fiber optic HDMI cable. And I'm pretty much set on using raceways in the corner of my room, along the molding and across the ceiling. Seems like an easier way to do things then taking down the ceiling. The nice thing is I can get 10 bit color at 4:4:4 and 4K @60Hz. That should buy me a few years!
