HDMI signal through Cat5?

06-27-2007, 02:46 PM

PSA - The people on this site are freakin' awesome. Just reading/searching/posting around here some, I've really found some good advice and ideas.

I have two Cat5 wires coming out of the walls at each major TV viewing area...such as my livingroom, bedroom, and entertainment room. What would you guys initially think these are for? From what I've investigated is that one is for Data and the other for Phone.

In my bedroom I already have the phone connected so they shouldn't be for that. I have two areas where 9 RG6 wires and 2 Cat5 wires are visible at each end, one being where the component cabinent is going to be and the other is about 10 feet away where my TV is mounted high on the wall. I've already connected RF to RCA adapters to 3 of the RG6 and now have satelite signal to my TV through component connections so I'm getting HD, but my idea is, maybe the Cat5 in my room is only run from the component cabinent to the TV like the RG6, so maybe it was intended to be used as an HDMI cable for DVD or 1080p gaming. What do you guys think? Is it possible to send HDMI signal through Cat5?

Yes it is, see: the DVI CAT-5 Extender (http://www.gefen.com/kvm/product.jsp?prod_id=3870)

The reason for two cat5s being run to each location is usually one for telephone and the other for internet. Satellite receivers use the telephone line and a HTPC would use the internet.

Yes, as Rbinck and I stated before it can. It is usually only used to extend very long lenghts of HDMI or DVI (200 to 300 ft). And the converters are quite expensive as you can see.... Don't know what you would use it for in your application.
Here is an example of the HDMI version:

Well I want atleast one HDMI cable going from my DVD player to my tv. Idealy I would have atleast two, that way I can have the ability to have a gaming system like a PS3 in my bedroom. I am hoping to use the Cat5 to do this, but the way it sounds, being able to send signal 150+ feet, I should set this thing up at the component hub of my house and just have the PS3 and DVD player there instead of trying to have the Cat5 convert into HDMI only in my bedroom.

I was climbing around the attic space above my bedroom last night and found that ONE of the Cat5 cables coming UP from the wall/outlet is actaully running across my attic/house so much to where I couldn't see it anymore and the other one is running from the outlet straight to where the TV is mounted. So I thought maybe I could convert this Cat5 to HDMI at the outlet and again behind the TV with such a device, but that doesn't seem logical now, or the "right" or sensible way to do it.

If I sound ignorant on this matter it is because I am...so thanks for hangin' in here with me.

If you get or have a PS3, you already have a DVD and Blue Ray player all in 1. So you can ax the DVD player. Just get a HDMI cable for like $25 and connect that directly from the PS3 to the TV. Or if you have a HDMI SS reciever like this 1, just hook it to that and 1 additional HDMI from the receiver to the TV. You can also hook everything else like your sat box to it as well. Just a easy solution...


An HDMI cable will run you about $30 for a 6 ft. ot $45 for a 12 ft.


Even cheaper at monoprice .com

I wanted to get some advice on an idea for sending - HD content to three TVS from one Comcast box (less than 300 feet - I think).
Like others, I have 2 cat5 cables going to each monitoring location.
What would be the best solution:
I have looked at the Gefen - EXT-HDMIIR-CAT5 (599) with IR, the Mux lab:The VideoEase HDMI Econo Extender Kit (500400) ( much cheaper - 249 w/o IR - would have to add something like the: /Xantech-Xtra-Link-2-172-94/p. to send IR signals to the source box over coaxial)
I have also looked at wireless options: Gefen (999) and Brite-View BV-2500 HD Wireless Video Transmitter/ Receiver Set (338)

Has anyone tried this - Maybe it is not worth saving money on renting individual boxes for each room - but then why did we run all that cat5 cable? We use wireless internet.

I want a flat mount with no wires over my fireplace - that's all!!!!:what:

Have you considered buying some CL2 rated HDMI cables and running them in-wall to your TV?
