Connecting a computer to the screen on my home theater system

[Bradley Burton]

This is complicated, and I'm not sure if anyone can actually solve this, but
I thought I would ask. I will try to explain this as best I can.

I looked up how to hook up a computer to a TV online, and it basically says
that the way to do this is to connect the cord from the video card in my
computer to the video input (the yellow socket) on the TV, then switch it to
aux mode.

I'm having problems sending my computer image to my screen because I'm using
a projector, so I don't have a TV where I could just plug in the video cord
from the computer to the TV.

My AV receiver has tons of sockets (not sure if that's the right word) in
the back, however in the front, just like a TV, it has, for Aux 1 input, a
video, L, and R sockets. I plugged the cord into the video socket, turned
on the system, and switched the receiver to aux 1 mode.

The computer picture is not showing up. Instead of the computer picture
showing up, the TV picture shows up (with no sound).

I have a cable box where the TV picture is coming from. It also has Video,
R, and L sockets too. Plugging the video cable into that also doesn't work.
Should I be focusing on the AV receiver or the cable box?

Also, I'm not sure if this part matters or not, but the projector itself has
8 different input options. I've plugged in the cord into the receiver,
turned it to aux mode, and tried all 8 options, and I still don't get what I
want. Should I be focusing on this too?

Any help would be appreciated.

Thanks, Brad

What Brand and Model of Projector are you using and the same for the
Receiver?

The projector doesn't have a connector like that, but it does have a yellow
video socket. When i pull out the cord in the video socket of my projector
for some reason the projector still projects the video. It's like pulling
it out doesn't do anything. Pulling it out and putting in the video
connector from my computer doesn't work.

The projector brand is an InFocus 7205, and the receiver is a Marantz
SR7500.

Ok. I do see those connectors on the projector. Do you know where I might
be able to find a cord that has an S-Video connector on one side (for my
video card) and a VGA or M1-DA connector on the other side? I tryed calling
RadioShack and CompUSA and they both said that they didn't have a cord like
that.

Thanks,
Brad

I guess you know something I don't, because for my first computer back in '81
or so I used a cheapo TV as my monitor. Just broke into the video circuit, and
fed the output from from my Exidy Sorcerer into it.

Used it to write basic programs, kids played games, wrote a (very simple) word
processor for it in assembler, and although I never was able to afford to buy a
proper computer monitor it served me to write all my uni assignments for a
couple of years.

But having been out of the TV game for some time now, I guess things have
changed and the defn isn;t as good now as it was then - or ???
