If you are looking for a way to display the screen of an Android phone using a projector, as people sometimes do on a demo, then you can do it using a PC / laptop by running Droid @screen ( http://droid-at-screen.ribomation.com/ ) on a PC and connecting an Android phone using a USB cable to a PC.
So, in this configuration, you have a smartphone → USB for PC → HDMI for the projector or LCD.
hope this helps!
