Hi Folks. Help please. I am a teacher and I want to use my tab 2 as a wireless device so i can walk around the class while using things such as powerpoint. What I need is a way to connect to a vga projector being wirelessly to my Tablet. I know apple users can use a apple tv box; a hdmi cable to a converter box that thing as a cord that connect to a vga projector. I see Samsung has a Allshare Hub, but can this only be used for a Galaxy Note and Samsung S3? Any help would be great. Cheers.
