Do the small "pc to TV converters" on Ebay let me put a pc monitor screen up
on my 20-24" TV screen?

If so, how do you configure it for channel, etc.?

There are several options for converters.

The one that consists of a cable, is only for special situations.
The old TV sets have interlaced displays, with 60 fields per second
and 30 frames per second. The video card on a PC, would need an
interlaced output mode, to drive a simple cable scheme, to make
video conversion possible. If you cannot see an obvious choice
in the display control panel for this, I wouldn't count on the simple
cable to work.

A second type, is in the form of a small box with connectors on
it, and it usually includes an external source of power.
Such a device might be referred to technically as a "scan
converter". It converts progressive output from the PC, into
interlaced video for the TV. The output connectors may include
composite (75 ohms) or S-video (DIN connector with four active
pins, Y, C, GND, GND).

The controls on this one, allow adjusting the size and offset of the
picture, as it is sent to the baseband input on the TV set.


When using composite or S-video with a TV set, you don't select
a channel. That is because both composite and S-video, are
"baseband" signals. They aren't modulated like a broadcast TV
signal is. You would need a modulator box, to convert from
baseband, to channel 3 for an antenna.

On my TV and remove control, as I scroll through the channels,
and reach 4,3,2, the next choice down is "Video". That choice goes
to the 75 ohm RCA connector on the front of the set. I can
plug in a video signal from a PC there, or I can plug in a
CCTV camera. The "video" selection on my remote control,
selects that connector as an input.

If I had a scan converter, it would have to plug to that RCA
connector, because composite is all my TV has for connectors.

Modern LCD TVs have a wider selection of input connector
types, and some even accept a VGA connection.

Also, modern PC video cards have a DIN connector on the faceplate,
for TV output. An S-video to composite dongle, can be used to
get composite output from such a video card.

If you have a laptop, then a scan converter is the most likely
route to driving a TV set. For a desktop computer, a different
video card might be the solution.

You should link to exactly what kind of product you're
talking about.

Generally, how you config your TV to show the signal depends
on what output the PC to TV box has.  For example if it has
S-Video, your TV would have S-Video input (else you wouldn't
choose that type of converter) and your remote or TV menu
would allow selecting S-Video input... or Composite, or
DVI... given today's TVs some of them have a lot of
different input options, so look on your TV back and in it's
manual to determine which it supports and then which of
those is the best quality, and use the best quality option.

Then again, a 20-24" TV screen, what is that?  Specifics
help, if the resolution isn't too high you have more options
without as substantial a degradation in signal but even so,
keeping the signal digital is highly desirable not just from
a quality perspective but from a 1:1 pixel mapping

Also, ebay is a look into a world of products that may or
may not be as good as other branded alternatives.  IOW,
there's some cheap Chinese/et al. junk out there that is not
as good given same specs as you'd find buying a major
branded product.

Do you have an s-video out connector on the back of your graphics card? If
so, then that is the yellow lead for a scart connection. Job done!

Re: pc to tv converter

Wow!   Great answers.   I am an obvious newbie on doing this.

What I was thinking of doing was putting a web site on my pc with brings in
lots of news (without all the prexy minute-to-minute stuff) channels.

Then, putting those screen shots up on my TV channels.

Now, I'll have to go and examine what my pc output is and find what the tv
has for input, etc.

The Aver thing is nice.

I believe you guys have given me enough stuff to get me started OK on this
project.   I'll come back if it isn't.

Again, thanks.
