I have been trying to connect my older Zenith television to my ATI video card as a second display. The ATI card would sense that my Toshiba tv had been connected with no difficulty and show it is as active . But with the older Zenith tv, it will not sense my connecting it unless I run the connection through the VCR. If I connect the video card RCA out to the television aux in, the card will not sense the tv and activate it as a second display device.
zenith tv with four video 'source' options listed in the menu:
antenna cable VCR Y/C
the RCA jacks on the back of the television look like this:
VCR-1 Aux video: O-------O audio: left O-------O right O-------O loop
Now that I have put the video card 'out' cables to the VCR's 'line in' and then put an RCA cable from the VCR's 'line out' jacks to the Zenith tv's 'VCR-1' RCA jacks, the ATI card in the computer at least senses that the Zenith tv is connected, but there is still no desktop displayed by the tv in the Y/C source display.
I have tried using double RCA plugs and splitting the 'line out' from the VCR. This is essentially a way of connecting two RCA cables to each 'line out' (audio and video) which then gives me two video cables out from the VCR and two audio cables out from the VCR. I then connected two of the cables to the VCR-1 jacks, and two of the cables to the AUX jacks. This did not work either.
Please help with this. This Zenith tv was connected a few years ago to my computer, and it worked as a display, but I forget how I had it connected then.
btw, if this is any help: The wall-cable for cable television is connected directly to the Zenith tv. It is not being looped through the VCR (as I do not have enough short cables to loop it)
Also, now that the ATI card senses the zenith, If I directly connect the RCA 'lines out' from the video card to the 'aux' RCA jacks on the back of the tv, it still does not show my desktop display. The screen stays blank.
