Thanks for the advice, eugovector.

I should probably clarify though.
I already have a 17" Samsung LCD and the viewing angle is wide.

My fiancé's sister plans on getting us a big screen for our wedding next year so buying a TV now is superfluous.

The LCD can jump back and forth from my studio workstation to the entertainment center to act as both the TV and a monitor for the video feed from my studio live room (aka. bedroom).
To do both of these I need a converter of some type and I don't really know what to expect in terms of performance and economy for the converter.

Once we get the big screen the LCD can stay on the workstation and be a full time computer monitor and camera feed from the live room.

I wondered if anyone has done this conversion and if it is of full LCD resolution from the DVD and NTC/PAL digital video camera.
I don't want to spend $90 on the converter to find that only 8" of the LCD screen is used by that source.

Will I get the full 17"?

Will it look as good as pictures from my PC?

Thanks for any info!
The device you're looking at supports a conversion of S-video to the following resolutions:

640x480 (VGA), 800x600 (SVGA) and 1024x768 (XGA)

Someone can correct me if I'm wrong, but I believe that your LCD will use only the # of pixels that it receives from the converter box...so how much of your screen is used will depend on the resolution of your monitor. For instance, if your monitor's resolution is 1280x1024, then you'd want to select "XGA" on the converter. If it only displays the 1024x768 that are fed from the box, tt will then use about 75% of the screen vertically and about 75% horizontally. Taken together, that would be <60% of the screen area. If your monitor resolution is 1024x768, you'd be fine...set the box to "XGA" and the screen would be filled.
<EDIT: note that eugovector, in the next post, points out that I am incorrect on this.>

But, if by saying "the viewing angle is wide" you mean that it's a widescreen aspect ratio, then that will also be a mismatch with the converted signal. The VGA, SVGA, and XGA are all 4:3 ratios (like your current 13" TV), so you also have that issue. If you actually meant the viewing angle is wide, e.g. the picture remains bright as you move your viewing location off-axis, then ignore the aspect ratio issue I've described.

And, converting from S-video to VGA will NOT give a picture anywhere near as clear as the picture from your PC. The PC is set up (or should be) to output the same resolution as your monitor. So, if your monitor's resolution is 1280x1024, then your PC resolution is set to the same values and is feeding out video information for over a million pixels (i.e. the ratio of output to display pixels is 1:1). With that set-up, your picture will be clear. An S-video signal is much lower resolution than the monitor, and therefore the converter box will have to interpolate information that's missing (i.e. it will "predict what the missing data...or pixels...should look like, and display that prediction). The picture will look much softer than from the PC...more like a typical standard def TV (and that's if the converter does a good job).

I'd highly recommend considering a television that can double as a monitor...it won't be a whole lot more than the box (which is approaching a benjamin), and you'll be a of a lot happier over the next year...while you wait for the big screen to arrive.
