It seems like a feature every phone should support.
I would like to have a phone mirror the display to the dvd player in my car, which has composite inputs. 3.5 jack to composite is perfect. it would be nice to have google nav on a big screen, and listening to Pandora at the same time..

Your post made me curious about it, so I did a bit of searching. It seems the only phone capable of it is international (I guess this means non-US) versions of the Samsung Galaxy S. Then there are some tablets with this ability, particularly from Archos. But phones, it looks like it's only the Galaxy S.

The reason this isn't more widespread is that if a modern phone will go for video out, it'll be HDMI.

That really is a bummer. I don't think that will work for composite video. I will do some searches, but i think my goal its now doa

is it just me, or does this seem like something that could be enabled by a software patch?

You would need a extra pin in the headphone jack.. Beyond that it should be only software. But i have a fascinate and no one has found out how to enable it yet.

Why would you need an extra pin? There are more than enough in a standard plug, to carry a composite video signal.

Would just have to be a clever software package...

Pretty sure its hardwired through the headphone amp. Its a hardware thing.. Putting video through a headphone amp would not be desirable. Now, with a 5th pin for video (which my phone has) then yea. Should just take software. But no one has cracked it yet. :(

SGS i9000 has TV out on 3.5 jack you need the same 3.5 to RCA video cable as the one made by Nokia

i've used it before, quality is okay, it's RCA composite (think S-video quality in VHS), so don't expect much, it's not going to look like a USB to HDMI out quality

TL;Dr, experiments led to Revelation: only two signals minimum needed.

so I was being weird, and bored, and I actually have a headphone to RCA jack. so what do I do? I send audio through the video port, and I see that the audio actually does cause images on the screen to appear. they may be simple white and black lines, but yea. It still works. the only thing someone needs to do in terms of sending a video to a TV, is recording the screen, converting said screen frame-by-frame into the RCA video code, and then sending that through one of the headphone signals. (Either left or right) and then taking both left and right audio signals, converting them into a mono audio, and then sending it out to the other one. boom! done... I would do this myself, but I Don't have the app-making know-how.
