hooking up 2 HDTVs to one Cox cable DVR box


Has anyone ever done this? One TV in living room and one on patio. Plan to hook up 1 with an HDMI cable and the other with Component cables.

Figured I would ask the OT before I started.

To show the same channel on both TVs?

Should work. It works this way with Directv.

Usually doesn't work. The component and hdmi do not output at the same time. One cancels out the other. At least my attempt didn't work.

You best bet is to get an hdmi splitter. Plug the hdmi out into the hdmi in split, then the 2 hdmi out from the splitter into the two tvs.

ETA: I do this so when I have parties at my house the two tv are synced. When I want to watch another channel on the outside tv I changed input to the coaxial I have plugged in.

It works for my Directv box. I am pretty sure it will work for your Cox DVR box too.

Depends on the cable box. Might or might not work.

You will probably spend more on the long cable and splitter than you would on the extra cable box.

It worked for me last year with DirecTV but wouldnt work this year. The second TV would act as if a storm was interferring with reception. I tried several options:

TV 1 out of the box with the 5 pronged plug (dont know actual name) TV 2 out of box with coaxial cable.

Spliter on coaxial. Still no luck.

When I built the house I ran component cables from the living room to the patio, so that money has already been spent. Thus my need to have the living roon TV on HDMI and the patio on component cables. I know I will have to watch the same channel on both TVs and Idon't want to have to get another box, I give enought money to Cox already.

if it doesn't dual output through the box try it through an av receiver

What is your set-top box's model no? Your 5 prong plug is probably component vid (3 cables) + audio (2 cables).

I have HR23-700 set top box. I use HDMI to hook up my TV. And Component video+optical audio to hook up my Hauppauge 1212 HDPVR. It lets me record HD content to my HTPC. The only restriction that I face is both the cables outputs same content (which is expected).
