I'm buying an Optoma 3d XL to go with my HD67 projector. The problem I have is that my current system is a CRT projector with HD fury with a 9.2 surround sound system running from an Onkyo SR607 receiver. From what I understand, as this is HDMI 1.3 only, it wont support 3D through the receiver (I will have 3d from Sky as well as through my PS3 and bluray player and will also have an xbox 360 linked up so I have four HDMI sources. Do I need to upgrade to the Onkyo SR608 which is 1.4 HDMI compatible or is there another way of having all four sources, including 3d, linked to the projector without having to unplug everything all the time. I've looked and I cant find HDMI 1.4 switches anywhere. I dont want something thats going to be really complicated every time I want to switch between sky, xbox etc. Any help greatly appreciated.
