None of the Nokia Internet Tablets (770, N800, N810) or the N900 have an HDMI port. The N900 has a dual use 3.5mm audio jack that can put out analog NTSC or PAL video if you can get it to work right. It would be really nice to have micro-HDMI port on a future device, but as yet, it is not an option on any of the current Nokia Maemo devices.
