The HDMI cable I got did not display anything on a TV. The LCD display I purchased did not work and the vendor from whom I purchased could not provide a solution other than pointing me out to some website for guidance. I had a very frustrating experience with my first Raspberry Pi Model B board and found it very difficult to boot. You can see the complete description and specifications of this latest model at the following link. A faster 64 bit processor running at 1.2 GHz.
What makes it different from other previous models are : A newer version of Raspberry Pi, Raspberry Pi 3 Model B has been released recently.
