If you have a notebook or pc with HDMI output and a big LCD TV with HDMI input, you might want to connect those. Unfortunately, this doesn't work out-of-the-box with the Dell Studio 15 notebook, neither with Vista nor with Ubuntu.
Now I got it working both in Vista and Ubuntu (8.10 - Intrepid Ibex).
This article describes how I installed a dedicated setupbox, based on Elisa, running on the Ubuntu Linux operating system.
My digital camera (a Canon Powershot A550) has the nice feature of saving the orientation of the picture in the EXIF information (it has a sensor to detect this at the time you take a picture). Some software, like Eye Of Gnome seems to automaticaly show the picture in the correct orientation.
