The Home Cinema 5020 is pretty average when it comes to inputs and connectors. As usual, our tour of the panel begins on the left. Two HDMI 1.4a inputs, capable of Blu-ray 3D, are on the left.
Continuing to the right, one set of component video with the usual red, green and blue RCA jacks, followed by the obligatory composite video (yellow RCA jack).
The Epson Home Cinema 5020 and the other variations, each have the usual, analog computer input (HD15 connector) for a monitor out.
Next over is serial port, RS232C and a 12 Volt trigger to control a screen, or an anamorphic lens (Epson 6020). There's also the power receptical, hard power switch, and a Kensington lock slot.
Of note, there is no S-video input, as was the case last year. I notice that this year that a number of projectors have been dropping S-video. I do not know if the EU or other versions have that jack - it's possible.
