How to connect an Android tablet PC to a projector?

Hello everyone, I connect 7 inch android tablet PC to a projector for view photos, PowerPoint presentations, watching video, viewing an app, etc. The HDMI output port on my tablet PC is very useful for these purpose. Most of the android tablets have an HDMI or a mini HDMI output port on them.

My tablet have a mini HDMI output port on it. When i connect it in difference sizes, i use an HDMI to mini HDMI cable or HDMI female to mini HDMI male for new projector. Sometime i use old projector, i need 3-in-1 mini display port to display port HDMI/DVI/ adapter or 2-in-1 mini HDMI display port to VGA adapter. So you can go to buy every tablet PC sites or tablet PC store.
