Any issues with 50' HDMI cables?

I have a client who is building an addition to his house. He's putting in two home theater areas (one kind of high end on 2nd floor, one low end on 1st floor). The AV/network/telco utility closet is right by the main home theater area on 2nd floor. The TV is going on one wall about 20' away from the AV/network/telco utility closet. My thought was to purchase one 25' HDMI cable and put in an HDMI Coupler keystone and short HDMI cable, to hook up his new flat panel TV that is going on the wall then run the 25' HDMI cable back to the AV closet where the sat receivers/BD players and all that stuff is.

He has a second home theatre on the first floor about 50' cable length away from the AV closet. I've read conflicting stories when doing a Google search about HDMI max cable length, most of them saying technically the HDMI spec doesn't have a maximum cable length, but a spec for loss@certain resolutions in order to stay compliant with the HDMI standard.

Are 50' un-amped HDMI cables okay for that length? Is it necessary to get HDMI baluns & CAT5e/6 to hook up that TV?

If the cable is decent enough it'll work, but it depends on your equipment's tolerances and whatever other interference is around it. Digital is all or nothing though, so it'll work or it wont. No fuzzy picture just blockiness -> black

I've got a 50+ ft hdmi cable run up through a wall and through my attic and back down into another room for media center recording. It's a 50 ft cable from monoprice.com http://www.monoprice.com/products/pr...seq=1&format=2 going into wall jack. plus cables on each end for termination. it works great.

Ok to be serious.

Being a cable installer for Comcast. I can say that it depends on where the source is. Will it have digital boxes for direct tv or Comcast or whatever? Or is this straight up blu ray to tv?

Are you saying you want everything to be in this a/v closet and run cables to both tvs?

BJC says their Series-1 cable is certified (non-highspeed) at 45'. link

Since the client didn't give me a lot of notice before the insulation and drywall is going up (next Wednesday in fact and wants HDMI cables run Tuesday the latest), I'm going to gamble and hope that 50ft HDMI cables work. I ordered them yesterday and they should be here today. I'm also getting a few right angle adapters so that I can fit the cable into the boxes with HDMI coupler keystones, since most HDMI cables of this length are beefy cables that cannot be bent easily (and not recommended to severely bend the HDMI cable of course).

The cables are being run from the AV closet on the 2nd floor to both home theater areas. The client has or is getting DirecTV installed and the HD receivers are going in the AV closet as well as whatever else he spends his money on (he was pretty vague with the details).

The HDMI cables are High Speed, CL2 Rated, with Ethernet, 24AWG.

I also read the BJC web site.

If it fails to work, well then the client will have to get HDMI baluns and have additional network cable drops installed. Honestly that shouldn't be terribly difficult for the main home theater area since there is one wall and an attic to chase cables through. The downstairs home theater area would be more difficult. The client has the EC running all of the network cabling anyway. I'm just hired to terminate and set up the network equipment. EC didn't know much about HDMI.

You can mod your box (comcast its easy).

Or, buy a thingy that sticks into the box in the back and its a wire, run it near the tv.

yeah, dish network uses RF for their remotes, that's how they setup up TVs in different rooms using only one box

From the studded wall outlining the AV closet, it appears that my client is going to put the front of the AV equipment facing the room, with the rest of the equipment inside on a rackmount shelf. For the rest of the house, I assume some type of RF or IR blasters. I don't know the specifics. The client is either doing that himself or hiring someone else to do that part of the work.

Run a pair of network cables along the HDMI just in case you do have to use a balun down the line. I've had clients who accidentally bust their HDMI tip and this has saved them a large amount of dry wall damage.

or use wall plates like these so there's nothing sticking out and the internal cable is safe.

or these snazzy hdmi over cat5/6 adapters
