Hi! I would like to connect both my projector and tv to my vga via hdmi at the same time so that i wouldn't have to get up and switch cables every time i want to switch between the projector and the tv. but my vga has only one hdmi input. what is the name of the device i am looking for? "hdmi splitter" or "hdmi switch"? And can you please suggest a good one for my 1080p 3D system? Thanks!
