I am a preacher and use Power Point with my laptop many times every week. My projector is suspended from the ceiling of the church building and DOES NOT have a HDMI connection. I have just purchased an Android tablet, Acer Iconia A500, 32 GB and want to know if there is any way to connect with that projector? The only connections on the projector are: RGB, VGA, S-video , and a remote plug. Can anyone help with this, please?
