I'm betting it is. Try this: Do a video playback, then send a text message (or something that activates a yellow "swoop in" message). You'll see the message on the device screen, but NOT on the video output. That implies to me they're two separate things. (Or one doesn't support a layer the other does?)

Yes, if it is just some kind of raw video overlay, it isn't very interesting (unless there's some hackish way to put a second display on that overlay 
)
)

I think it's only suitable for what the sales pack says "Video sharing and playback".
TV out (PAL and NTSC) with Nokia Video Connectivity Cable (CA-75U)
Can't imagine working on the N900 and a secondary display like I do on laptops. Also, a mouse/pointer would be necessary. And the hassle to work and manage calls with a wire to the monitor would be troublesome.

In my early N900-days when I played with the TV cable and my TV I got a call just when I had my N900 screen on the TV. Usually the screen should turn off during a call but the TV screen didn't turn black.
Additionally the output can be switched between PAL and NTSC and both produce slightly different images on the TV screen (my TV can handle both).
So I'm pretty sure that the TV out is handled seperately. But the question remains if the GPU can handle more than one display. I can't check right now, do you see any useful output in Easy Debian when you connect your N900 to the TV and issue the following in a Debian terminal:

I have one of these devices to use the N900 on monitors.
Using it as a 2 nd monitor should be possible, since mplayer used "xinerama" and you can see a video output to the TV and see the emails in the N900 screen.
I hope you get to make it possible for any application.
One idea is to use the media player controls on the screen of the N900 and the movie on the TV output.

i just checked xrandr and this is what i got from maemo using xrandr from easy debian:
so it seems like there is only one screen detected which has a maximum resolution of 800x800.
i have no explanation for the xinerama/mplayer thing.
Edit:
Just for clarification, this was the output when my TV was connected, but it's the same when the TV is not connected.

As far as I understand, xinerama is used to stretch a single work area across two X displays; why is that used to display the video overlay on a second display?
I had an nVidia graphics card that had this same feature. You could have it display just the video on the second display. But it also could be configured to use the two displays as one big work area (xinerama).

"TV-out is an area that is neglected by the XFree86 developers, mostly leaving it up to third parties to provide extra drivers etc."

Oooh, you think it could be that easy?
EDIT: I don't think it is that easy (just adding a Monitor section to an xorg.conf file)

All times are GMT. The time now is 04:17.
I just purchased a little adapter that converts composite out to VGA, and I began to wonder what exactly the TV Out of the N900 is displaying.
Is it simply a hardware thing, it shows whatever is on the internal display, no matter what? Or is it display :1 or some other user-modifiable output?
The fact that Maemo can display something different on the TV when you're watching video suggests that you can use the TV Out as a secondary display.
If you can throw something else up there, I of course want to be able to throw a secondary X display onto it.
Any ideas?
