I think pushing video to the composite out while keeping playback controls on the LCD works because only the control screen is RGB. I'm fairly certain I've read the OMAP3 is limited to mirroring for RGB and independent displays for RGB + YUV. Digging into docs and discussion on the BeagleBoard would probably be the quickest way of confirming or denying that.

I remember Lcuk attempting dual, independent displays with his code since liqbase is all YUV. You might try pinging him. I don't know what success he had.

Yeah I have a feeling that the independent TV Out display is an XV overlay. I'm getting the distinct impression that a second desktop isn't possible.

Hmm, are there any window managers that will run on a specific XV plane?

Afaik, the Pandora has composite TV-Out and can display something different on the second screen than on the built-in LCD. Of course I don't know how it's tv-out hardware differs from the N900's.

Hi qole, sorry if I'm bothering.

First of all, I don't know if I understood your question. I just know that I bought about 3 months ago the SAME thing for the EXACT same reason (except that i got mine from ebay for $23). Since then, I've been experimenting the TV out, and one of the big "pointers" I got from this thread:
http://talk.maemo.org/showpost.php?p=461660&postcount=9

And then by tinkering with it, I discovered that this works only with the "tv-out" display, not with the "main" display or anything, so I, for instance, have to do something like this (while PAL is selected in the settings - and will owrk only once for that reason - I have to change back to pal to try another resolution that will work):
"echo ntsc > /sys/devices/platform/omapdss/display1/timings & echo 59,30 > /sys/devices/platform/omapdss/overlay2/position & echo 640,500 > /sys/devices/platform/omapdss/overlay2/output_size"
While the film is running (like in Kmplayer and SiB or Mplayer or Any player that plays while in the background) to make the screen resize.
I was also trying to work on how to crop and resize at the same time, but no luck till now (actually I didn't try until now).

And then I've seen this thread:
http://talk.maemo.org/showthread.php?t=68294

AND this tip (that I didn't even try yet):
http://talk.maemo.org/showthread.php?t=68294

And that's all my "knowledge" about the TV out. I hope I could have helped someone.

Bye!

Is it possible to turn the tv screen into black when connected? When I lock the phone the tv is not turning black. Want to use it as musicplayer at home, but I don't want to display anything on the tv.

Unplug the yellow cable from the TV.

Or start some application that shows a black screen (e.g. black image in full screen).
