| I'm wanting to buy this adapter to get a Video signal from my laptop to a LCD HDTV via an upscaling converter. Iam puzzled by the audio outlets. I understand that the VGA is only a video signal, why put audio outlets?
Can anyone enlighten me?  | ||||

| That's probably component video, not composite video and audioL/R. | ||||

| That adaptor is for a specific device that includes audio and composite/svideo on a D15 port. It will not work with "normal" VGA ports at all. | ||||

| Thanks Guys, I'll buy it anyway as I'm sure the video outlet will work and it"s only $4. | ||||

Why are you sure the video will work? Composite/s-video is not standard on VGA ports (although some graphics cards and laptops have it on some of the otherwise unused pins). A simple cable can't convert VGA to composite/s-video. | ||||

| The titling makes it look like it will work, but the price guarantees it won't. There would have to be some special electronics to make it even possible, but there's no way it could have that and sell for $4. | ||||

| You will may need a VGA to s-video scan converter:
http://www.cablestogo.com/product.asp?cat_id=3103&sku=27389 Note that s-video picture quality is far lower than VGA, even with the best scan converter. At best, the luma resolution will be about 640x480, the chroma resolution about 320x480. | ||||

| I'm not trying to convert anything with this. I am sure I can get a video signal which I can convert this upscaling converter. I'm not going to slash my wrists over a few bucks, so if it doesn't work then too bad.
At my age my eyes are not that brilliant and the whole exercise is just something to keep me busy. I'll let you know how it transpires.  | ||||

Won't work 99.98%. I'm tired of explaining the 0.02 % times it may work. | ||||

If it works let us know. If it doesn't put some screws in that knife door. All that does is poorly display SD composite at best. | ||||

That doesn't make any sense. You want to take composite or s-video from you laptop's VGA port (if it even has it) and the convert to VGA to feed a monitor? Why don't you just get a VGA cable and feed monitor directly? The picture quality will be far better. And you still haven't said why you're so sure you can get s-video or composite video from the laptop's VGA port. Does the manual say your laptop has that ability? Does that cable manufacturer say it's for your model laptop? VGA and TV video are two completely different, incompatible systems. | ||||

You will get a much worse picture, not a better picture. | ||||

I bet you a couple of beers that I won't :lol: :lol: I should be able to tell you in about 10 days, at that stage I'll be either gloating over my win, or humbly apologizing. Don't worry mate, the sun will still come up, even if it's a dismal failure. :) | ||||

| It's not a matter of faith. It's an understanding of how TV and computer video works. |
