There's just a few pixels on each side that don't fit and I'm pretty sure they are pushed in via anamorph.
Unless you get at least megapixel display (720p), HDMI is a complete waste, a drain on battery, weight, computing power and more stuff to break - ignoring the fact that HDMI connectors are complex, large and the cables are rigid relatively, making it an easy thing to break.
The only thing that's keeping HDMI from being taken into the woods and shot is the fact that it pipes HD video and audio with zero loss. Heh.
For a start, HDMI would mean a 480p/576p pure digital signal, component is a 480i/576i very lossy (aka fuzzy, poor colours) analog signal. Its also a lot easier to plug HDMI in to modern TVs, my TV has HDMI on the left side but component is on the back REALLY hard to get to.
There would also be the possibility of switching the N900 into dual monitor mode (assuming it can support this in hardware) so you then could have 720p+ externally with the LCD still at 800x480, for presentations/slideshow (display photos taken on the N900 at full resolution), full desktop, or even single-monitor (external only) where you run a kiosk off an N900 instead of a PC, using the N900 screen as a touchpad to control the mouse pointer. It may even be possible to do this now, but with component the only option for output its kinda pointless as the picture quality is so poor.
Basically, it would have made the N900 more of the PC they claimed it to be.

But the point is, had the N900 supported digital output it needn't have output a SD signal, it may very well have been able to do at least 720p for picture viewing and web browsing, which would have been really useful.
You will actually find that the video will look better on a SD TV - most HD TV's do a terrible job of up-sampling SD video. Furthermore the comb filters (filter that separates the luma and croma in the composite signal) in modern TV's are really bad these days so composite video really suffers on them.

The TV out is a full clone of the display.

BTW, isn't there a mini-HDMI port? I think I've seen some cameras with it... you use a special cable and get a normal HDMI male connector but the female connector in the camera is pretty small..

) http://en.wikipedia.org/wiki/Hdmi#ConnectorsThere even is a specified micro hdmi plug, but lets not go down that road - imagine if we had to contend with micro HDMI plugs fallign off as well as micro USB
All that said remember that the plug on the N900 is not only video, it works with headphones and the FM antennae too. If there was a HDMI plug there would be a requirement for a seperate headphone plug.

(although to be fair, so does VGA in some circumstances)
You mean composite.
It is also true that many TVs have composite readily accessible. But it stands to reason that with HD being the "big thing" that more TVs with a front/side HDMI port will be common. My TV is already over a year old and has HDMI on the side with the composite relegated to the back.

Or maybe a special microHDMI connector that can accept HDMI or composite adapters. Whatever, I think it was narrow minded for the N900 to only have composite output when it would have been a true PC replacement if you could output a full desktop over HDMI, we know its powerful enough CPU wise, its just if the GPU would handle it (but I would think so).

Personally I really wish they would have put the headphones port next to the USB port, for easier docking (would be particularly useful for in-car mounting). Or possibly a microHDMI port next to the USB. The N900 is by no means optimal IMO, heck I even would have liked answer/hangup buttons but now I am getting off topic.

Hi everyone.
I have been looking for a thread like this for two weeks and finally come across this today, thanks god (or thank you actually.)
I am looking for a way to connect my N900 to digital LCDs too, those without composite ports. But it seems I haven't tried hard financially!
I bought a $10-composite-to-VGA adapter, the one with female red-white-yellow and S-Video ports and male VGA port. However I still can not make my LG monitor (W53 Series) recognize the signal from N900.
The LG monitor has HDMI, DVI-P and VGA ports.
The N900 connects fine with, I think, any TV -- LCD or CRT -- with a red-yellow-white composite port, but without the composite port, no signal -- hopefully only in my case.
I guess the converter I bought just simply convert the phisical pins from the composite pins to VGA pins, but what I expect it should do is converting the analog signal from N900 to RGB signal the monitor can recognize.
There are only PAL and NTSC option in the TV out setting. Wishing it has RGB option so I can try.
Anyone be better luck with connecting to VGA monitor?
