    I'm thinking of buying the lightning digital a/v adaptor for my iphone so that I can display the video and audio on a tv. My question is, does anybody have a recommendation on something that can convert the hdmi output to a composite rca cable. The reason why I need this is because I plan on using this setup in my car for the kids in the back seat so they can stream netflix of something while we go on a long road trip. The problem is the built in entertainment system doesn't have an hdmi input. It has the old school red, white, and yellow composite rca jacks.

    It seems that the only thing that Apple offers that allows the iphone 5 to output the a/v is the lightning digital a/v adaptor. I'm then thinking of buying an hdmi cable to plug into some kind of device that can convert the signal to composite rca. I'll then buy an rca composite cable to plug into the output end of this convertor device and then I'll plug the other end of the composite rca cable into the entertainment system in the car.

    I found one from Etekcity. Has anybody tried this or heard of it and if so, can you provide some feedback on the product? Thanks.

    Do you have an "old" (non-Lightning) 30-pin iDevice around? If you do, you should use it instead for streaming. It'd be FAR cheaper (Apple's 30-pin RGB cable is considerably cheaper than any HDMI > RGB converter), would take FAR less space, the resulting image quality would be FAR better and the cabling needs (including having to provide DC for the active converter) would be far less too.

    Also, if you have an Android / Nokia handset, even the cheapest ones support composite out. It'd also be a MUCH better solution than purchasing and using an active HDMI converter, unless you absolutely must display iOS picture on the monitor.

    My iphone 5 has the lightning connector and I do believe Apple does sell a lightning to 30 pin connector but on the website, it says that the 30 pin adaptor does not serve video signals. That's why I'm my question about an hdmi convertor because they do sell a lightning to hdmi adaptor.

    Sure I know (I've even tested this with my adapters and cables - I've been working on several video-related articles. Some of them have already been published here at the MR forums.)

    I recommended an old(er) model if you have one. For local video playback, even an iPhone 3GS would do as it already supports 480p/576p over the RGB cable. Or, if the quality of the composite cable is OK with you, even an iPhone 2G or a very old iPod touch would do. Those would be, in your case, FAR superior solutions than trying to hook up anything Lightning-based to an RGB-only monitor. For the latter, you absolutely MUST purchase an expensive HDMI > RGB active converter. For the former, you don't.
