I need to connect a PC to a pub-style projector TV, in order to
display the screen output to a pub full of viewers. I've not decided
yet whether to make up the presentation itself using powerpoint or
just use HTML pages, but that shouldn't matter?
I think the device I'm needing is some kind of adapter that will
provide a standard UK PAL TV output signal? like the old ZX81 computer
and it's cousins which used a modulator to display the computer's
output on a standard TV.
Would there be such a device suitable for a laptop (via the pcmcia
slot)? Or possibly, is there something that could plug into the normal
monitor output d-connector? Or alternatively, a PCI card that would do
I'm looking for something relatively cheap if possible, although
that's not the overriding concern, that will work on a standard UK TV,
and which could be ordered quickly within the UK.
I could use either a laptop or a desktop PC, but I wouldn't be able to
use anything that plugs into an AGP slot as none of the PC's I have
access to for this project, have one of those.
Hope this makes sense & you can help.
I will be not be far from my computer if you need to ask for
clarification, for at least the next couple of hours.

It's me again. I'm interested in your question and I would need to
know a few things:
1) Is your pub-style projector TV similar to an ordinary TV?
2) Does it have a coaxial port for coaxial cable where it gets its
3) Does it have a TV/Video setting, where TV is set to watch TV and
Video is set to watch VHS, VCD, etc.?
4) Are there any other ports available at the back of the television?
5) Does it have an S-video port? Does you laptop have S-video port?
6) Are you 100% sure that your PC's have no AGP port?
7) Is the TV capable of auto-detecting signals? If not, does it a have
switch for NTSC, PAL signal?
8) What is your definition of cheap? What's your budget for this?
9) Are you willing to buy extra peripherals just to accomplish this?
If you have other details to add, please do so. I'll be waiting for
your reply. Thanks.

Hi there Feilong.
Thanks for asking for more information..
The projector TV takes the same input as an ordinary TV; at the moment
an output is taken to it from the 75 ohm coax output of a normal video
recorder. As far as I'm aware, the video outputs on channel 36 UHF,
and the projector TV is then tuned to the channel the VCR outputs on.
Yes - see above.
Not that I'm aware of - just works like a basic TV, tune it to the
right channel & off it goes. But I could make double sure, see 7
Had a look from the floor last night, there seems to be provision for
sound output? via a phono plug, but nothing else. I'd need to get up
closer to double-check. See 7 below.
No, no S-video ports available on any of the PCs. Unsure about the TV,
I don't think so but I could check. See 7 below.
Definitely no AGP ports I'm afraid.
Unsure - it's taking a PAL signal at the moment, it *might* have an
NTSC facility / autodetect but unfortunately I can't get access to the
premises right now to check.
If you would like, I can probably arrange to go & check this evening -
if you would like, I could close off this question, and repost it
again tomorrow for your attention once I have more info - let me know;
I pulled a figure of 80 UK pounds right out of thin air yesterday, as
the cost of such an adapter, purely to check the look on the guy's
face who is going to end up paying for this. He flinched a bit, but
less than I'd expected. Later on, he mentioned he'd hoped it was going
to be more like 20 or 30 pounds tops. Having said this, I think he'd
be willing to go a little higher as he's fairly set on getting this up
and running; it's part of a presentation to do with a relative's
milestone birthday party coming up.
If extra peripherals are required to accomplish this, I guess that's
just the way the cookie crumbles! So yes, willing.
So, essentially I've not been able to fully answer your clarification
request, but could repost the question tomorrow with more info. Let me

I can readily answer your question because I've already been doing
this kind of thing to my computer. It's very easy, actually. The
reason why I asked so many questions is because I want to be sure and
because I might be able to give you several ways to do this. Things
would have been easier if any of the PC's have an AGP port because you
only need to buy a special AGP card with TV-out and/or Twin View
capability and a special cable (usually included with the AGP card).
Because you don't have AGP, I will need to look for other methods and
materials for this.
With regards to your proposal to close this question until you verify
things, I'll go for that. I hope you can:
A) give me the ports on your laptop, or give me the model and I'll
look for its manual.
B) regarding #3, if you can't find it on the TV, look for it on the
remote - if it has a one.
C) your confirmation to #4, 5, and 7
So if you'll repost this question, please don't forget to address it
to me. ;-)
Thanks. I'll be expecting this question tomorrow.
