S-video tv out

[Ingress]

Hi everyone,

I have Nvidia Geforce 8600 GT in my laptop from which I want the display to
a 21 inch CRT Sony Wega TV. I am using the S-Video to RCA connector but I am
getting no signal on the TV at all. I have tried reducing resolution and
colors to the lowest possible. When I enable the secodary monitor the
resolution and color in my laptop gets too bad yet there is no display on the
TV (just a noise). Can you please direct me to the source and possible
solution to this problem? Thanks in advance.

I could be wrong, but would you not need a "TV-out" on the
Video-Card to hook up a TV on the PC? the card I'm using has this
output. What does the manual for the LAPTOP say about hooking up a
TV?

The other question is if the driver still has this option.

Well the S-video(out) port of my laptop I have hooked my "S-Video to RCA"
connector to, is called a tv-out I guess. I have VGA and HDMI out too, but
not the cables right now. So using s-video which is a 7-pin output not 4-pin.
The manual of my laptop which is a Dell XPS M1530 says to connect using
S-video to component/composite video adapter and from that a RCA to RCA
connector. I guess that is similar with S-video to RCA connector unless you
correct me.

The picture on the web page, shows a minidin with 7 pins and alignment
tab.

It looks to me, like this. (One picture here, is the mirror image
of the other, and it may depend on whether you're looking at the
cable or the computer end, as to which view is right.)

There are more details here, indicating the pinout may not be
standardized. The adapter provided with your Dell computer may be
the best choice.

If you use the software provided with the video interface, you
may be able to see whether one or two "monitors" are present.
Sometimes, on a 75 ohm composite interface, a user has to
select "force detection", when the loading of the TV is
not detected. In this thread, you can see the amount of
floundering you have to do, to get a TV to work. Nvidia has
both the "new" and the "classic" control panel, and the new
one is austere compared to the old one.

On a laptop, there can be a hot key you can press, to select
the driving of an alternate display (check your manual). Judging
by the description of the computer in your case, there are multiple
output connectors, so I don't know whether using that hot key would
be more useful than using a control panel or not.

Quality wise, HDMI or VGA are higher bandwidth options. Depending
on what the TV supports, either one of those may give better
results. After having tried composite here, I wasn't impressed
with the results.

Hey Paul, thanks a lot. Yea mine is the non-standard 7-pin. Still the 1st 4
pins should be same as it says in Wiki. Well the problem is Dell didnt
provide the adapter. I have to order now. And thanks for the links. Those are
helpful. I was wondering whether the 21" CRT TV monitor has too low
resolution for 8600 GT, coz when I tried to enable the secodary monitor from
Nvidia the resolution got down to 800x600 with 8bit colors and the tv started
a noise till that secondary monitor was enabled. And the laptop does have a
hotkey for changing monitors, but that says "No external dislay", I aslo
tried with rigorous display detection but it failed.
Thanks again.

Hello,

Try another S-Video cable.. make sure it is properly shielded (i.e. thick
cable) and that no pins are bent.
