I am in the process of pulling HDMI cables to distribute HD signals throughout the house, can I cut the end of the HDMI cable off for easy fishing through the wall, then re-connect the adapter?

How far can an HDMI cable go without signal boost?

Thanks in advance.

You would have 19 conductors and maybe a shield to reattach. Seems like a lot of work. The HDMI plug is relatively small. Wiki HDMI Info has the pinout and a discussion on cable length.

There are other options out there. I believe several companies make HDMI extenders (HDMI from source to sender, 2xCat5e cables from sender to receiver, HDMI from receiver to display). There's also a company called RapidRun that makes modular cabling -- you fish the cable without any ends on it, and then you can field-terminate it with any of several 'pigtails' (including an HDMI version, if I remember correctly).

Otherwise, you're stuck fishing cables with the ends attached. If your walls are open, not such a big deal. If not, it can be a big deal!

I'm pretty handy with a soldering iron, but there is no way I would attempt to reconnect an HDMI connector. Aside from the number of pins, those things are really tiny. Those things are machine soldered at the factory.

And I don't even solder.

tlniec, thank you for the RapidRun link, judging from the pictures those connectors are not going to make my work much easier. Guess I will have to drill bigger holes than I like.

I had seen an announcment somewhere on here that some company has figured out how to convert HDMI to coax and back again - you might do some looking for that ?

Is that the $700 device by Gefen you were talking about? Well it is still vaporware and not worth the expenses unless it can do a lot more, such as network several receivers.

When looking at HDMI over COAX solutions it is worth ensuring that they are lossless - i.e. they don't recompress the video to reduce the bitrate and will pass a full HDMI signal untouched.

They say they can do 1080i now and is working on 1080p.

Yeah I think it was Gefen, but holy cow - that's pricey !
