Connecting Widows 7 to a Projector


J

Jack Gillis

Here is my problem.
I have a HP Pavilion dv1464dx Laptop running Window 7 Home that I need to
connect to a projector that has only an Svideo input. The laptop has no
Svdeo output, only a VGA jack for connecting to an external monitor. It
works. I have an VGA to Svideo adapter (the inexpensive 'Y' type) that I
connect to the laptop's VGA output and then connect its Svideo cable to one
of the Svideo inputs on my TV. Windows 7 detects the TV and allows me to
turn Presentation on. The TV accepts Svideo input just fine from my Cox
cable box. However, with the laptop connected as above I keep getting a 'No
Signal' message from the TV.

The laptop has a Mobile Intel 4 Series Express Chip set adapter which,
according to the specs, does support TV Out. Use of Fn+F4 doesn't yield a
picture on the TV. I am beginning to think something is inhibiting the TV
Out feature of the adapter. Could it be Windows 7 or maybe because HP
hardwired it out?
Is there anyone here who has successfully use the 'Y' type VGA to Svideo
adapter? If so how did you do it?
Will I have to buy one of the more expensive adapters priced at around $70?
The real question is this. Can someone help me get my laptop's VGA output
connected to the Svideo input of the projector?
I will really appreciate help.

Thank you.

From my (probably now out of date) experience, I'm guessing that the
Y-adapter has an S-Video cable that connects to certain pins of the VGA
plug that are not used by VGA.

That will only work if the VGA socket is wired to match.

My own experience with simlar adapters indicates that different
computers are wired differently, sad to say.

The upshot is that you need to find out if the laptop is so wired, and
if it is, you need to get an adapter that matches the wiring.

BTW, HP's manual for the dv1465dx (note that the last digit is a 5)
says this:
"External monitor port Connects an external VGA monitor or projector"

Nothing there about S-Video.

Let me add this: have you considered using a projector that has a VGA
input?

Thank you very much.
I would love to use such a projector but that projector is the only one
available in the place where we will use it and as I said it, sadly, only
has a S-video input

Time to borrow one? Or a laptop with S-Video out.

Or spend the $70 on the adapter. I'm guessing (hoping) that the $70
adapter is a converter: VGA in, S-Video or composite out...

Please understand that I am making (half-)educated guesses, so if you
find other information more to your liking, it's probably correct :)
