I have just bought an AppleTV off eBay and I am trying to test it to make sure it works, but I don't currently have a flat screen TV to try it with. I have a couple of good TFT computer monitors but both are VGA so I bought a HDMi to VGA cable off eBay which arrived this morning and neither monitor gets a signal and just displays 'Check cable connection'.

What's this more likely to be? A problem with the cable or the AppleTV? Can anyone suggest any other way of testing this?

I bet it is a resolution issue. Of course, you'll never be able to know for sure.

What cable did you buy? A really expensive one? HDMI and VGA are vastly different standards...

Without going technical - the cable most likely won't (and can't) work.

Maybe it's an HDCP handshake issue. Getting HDCP over an HDMI-to-VGA connection requires a special kind of cable.

You guys are clueless. The HDMI output on the AppleTV does not transmit an analog VGA signal.
You'll need an LCD with DVI input to test and an HDMI->DVI cable.

Adobe75 is right, the ATV`s HDMI out is a digital signal and the monitors VGA input is an analogue signal so the two are incompatible. However you may be able to convert the ATV`s compenent out to VGA, but I`m not sure.

Which is why I said he would need a special cable, specifically, one with a digital-to-analog converter in it. Such as the ones they sell here: http://www.hdfury.com/

Not worth it for the money, but it can be done.

Try the "component" green RCA out on the ATV and use a yellow "composite" lead to your TV.
It will only be black and white and wrong resolution, but just for working verification, it should do fine. HTH ;)

Now that is a really good suggestion if I ever saw one. I remember that option now that you mention it, but was obviously too focused on the OP's VGA to connect the dots that way. Nice.

You guys are clueless.

That on the other hand didn't sound very nice at all...

Thanks, that worked a treat :)
