I'm looking into setting up in-wall wiring and using HDMI wall plates for that clean, finished look. The problem is when it's all said and done, there will be 3 separate HDMI cables joined by two couplers. There will be 15' HDMI cable in the wall, 2' from the wall to the TV, and 6' from the wall to the receiver (I could always get a shorter cable).

With all these cables and couplers in play, should I be worried about issues with the signal? Obviously I'll test everything before it goes in the wall with a 1080p signal but I'm not sure what else I should look for. I'm a noob when it comes to this stuff.

Thanks!

If all your HDMI cables are Category 2, you should be okay.

TEst first and have a backup plan. Even without couplers, NEVER assume that HDMI will just work.

If it works, you're golden. If it doesn't, it will be very obvious.

I've seen good and bad couplers. The bad ones use wires between the HDMI female connectors. The good ones use a printed circuit board (PCB) between the connectors to keep the impedance as constant as possible and reduce crosstalk. So in general, the PCB ones are smaller and the HDMI connectors on the opposite sides are upside-down from each other (if you know what I mean).

Has anybody had any experience with the the NAC-KJACKHDMI made by Bergtek? (here's a link: http://www.microbarn.com/details.aspx?rid=102164)

The price is right, and I figure it will either work or not work, but was just curious if anybody had actually used them.
