From: yaugin on 5 Jul 2010 20:05 Recently purchased a dud cable from an ebay seller. However, more than it not working, I am starting to suspect that it's fake. It has a standard VGA dsub connector on one end, and a composite RCA video jack on the other end. The supposed function was to plug the dsub connector to a PC video card and the RCA jack to a TV for output. There's actually two output options, as there is an S-Video connector as well attached by a parallel wire. There's no indication of any transcoding circuit present on either wire, and all the connectors are standard size so I don't see that they could be housing such a unit. And upon closer inspection of the cabling itself, the printing on it says "USB CABLE". And without a transcoder I don't believe it's possible to convert anything from a VGA connector to anything with a composite connector because the respective equipment is working in different color spaces. So I'm guessing that there's really no function to the cable at all, it was just hacked together from surplus parts. I'm just curious to know if my suspicions are justified. Here is a photo. http://img15.imageshack.us/i/fakecable.jpg/

Before Buying. This item is a VGA VIDEO Card to S. Video or Composite TV Adapter Cable. Use it to connect the video card on your computer to a TV input. Your video card MUST be able to support s-Video or Composite out through it's VGA port. This is known as a TV out function. If you don't know if your video card can do this, then call the card manufacturer and ask them "Does my video card support S-Video or Composite Video out through its VGA port?" If it does, then buy this adapter. If not, then use Product # 4724 http://www.monoprice.com/products/search.asp?keyword=4724 Connector: VGA(HD15) Male to S-Video Female and RCA(Composite) Jack Cable: UL 2919 Coaxial Low Voltage Cable It will work with VGA cards that have TV-Out function capability through the VGA connector. Check your Video Card manual or manufacturer to make sure that your VGA card has TV-Out function capability. IMPORTANT: * THIS ADAPTER WILL ABSOLUTELY NOT CONVERT AN S-VIDEO OR COMPOSITE VIDEO SIGNAL TO VGA. IT WILL NOT WORK BACKWARDS. * YOU CAN NOT USE IT TO DRIVE A VGA COMPUTER MONITOR WITH A CONSUMER ELECTRONICS DEVICE SUCH AS A DVD PLAYER OR VCR. * IT IS NOT COMPATIBLE WITH NETBOOKS OR ANY CURRENT GRAPHIC CHIPSET." So there, if you bought it, then you should have read the fine print first.

That also depends on whether the eBay seller hides details in a tediously long item description full of advertising for the seller's business. Then again, to be safe when dealing with eBay, you should just avoid anything you are not familiar with. EBay is like the Mos Eisley spaceport in Star Wars. -- > Path: news.astraweb.com!border1.newsrouter.astraweb.com!feed.news.qwest.net!mpls-nntp-07.inet.qwest.net!195.114.241.41.MISMATCH!feeder.news-service.com!feeder.erje.net!eternal-september.org!.POSTED!not-for-mail > From: david <none nospam.com> > Newsgroups: alt.comp.hardware.pc-homebuilt > Subject: Re: Is this cable fake? > Date: Tue, 6 Jul 2010 01:01:13 +0000 (UTC) > Organization: A noiseless patient Spider > Lines: 67 > Message-ID: <i0tv8p$p9k$2 news.eternal-september.org> > References: <9ffcc544-9fe0-4584-ade9-696524e4948b m35g2000prn.googlegroups.com> <i0tv5p$p9k$1 news.eternal-september.org> > Mime-Version: 1.0 > Content-Type: text/plain; charset=UTF-8 > Content-Transfer-Encoding: 8bit > Injection-Date: Tue, 6 Jul 2010 01:01:13 +0000 (UTC) > Injection-Info: mx02.eternal-september.org; posting-host="j6YNSx4ZzkGtILp30gi9hg"; logging-data="25908"; mail-complaints-to="abuse eternal-september.org"; posting-account="U2FsdGVkX1+QBzFCIdDKnsI5f+z8KrIt" > Cancel-Lock: sha1:n0vBwslpl3drf77Me0NTdDIXrE4= >

Here is a > photo. > > http://img15.imageshack.us/i/fakecable.jpg/ To drive a TV set, with composite, requires an interleaved frame format for the signal. That kind of "passive" cable, requires that the video card have a special output mode, just to drive the cable. Some old laptops supported that, but I'm still waiting for an example of it actually working. Ebay and other sources, sell a ton of those cables, and the landfill sites must be full of them. For most people, a cable of that particular design, is a waste of money. You need documentation for your computer or its video card, where that specific operating mode is mentioned, before you buy that cable. ******* If you want better odds of success, you need an active device, such as a "Scan Converter". Scan conversion is never a high quality proposition, so if you find people who actually like the output they're getting, then buy it. http://www.newegg.com/Product/Product.aspx?Item=N82E16815158142 There are other products like that on Newegg, where the reviews aren't quite so glowing. The price has come down on scan converters, so now you can make a $40 mistake, rather than a $200 mistake. That's progress... http://www.newegg.com/Product/Product.aspx?Item=N82E16815276011 I think I've seen that particular one for sale before on some web sites. It has the adjustment buttons on the side. http://images17.newegg.com/is/image/newegg/15-276-011-S11?$S640W$ HTH, Paul
