I have a home cinema setup in which I use my PC as the main source. Up until now, I was using an old AV receiver that didn't support HDMI, and so I used the optical Toslink connector to connect the PC to the receiver for audio, and then an HDMI cable from the graphics card to the projector.
My old AV receiver now died, and I replaced it with a new one that I've (at the moment) connected up the same way. I realise though that this is sub-par because Toslink is old and doesn't support the newer audio standards (EAC, TrueHD, etc), so any unsupported signal will end up getting downmixed to 2.0. However, the physical layout of the computer, receiver, projector makes it very cumbersome to draw an HDMI cable from the PC to the AV, and then from the AV to the projector (I probably need a 20m cable that will essentially double back past the PC and to the projector).
Would it work to buy some kind of HDMI splitter that clones the signal so I can send it to both the projector and the amp? What kind of issues might I run into? (Sync? DRM stuff? HDMI handshake between AV/PC or Proj/PC?). At the moment, the setup is quite convenient in that I run the monitor off one gfx port and the projector off the other: as soon as I turn on the projector the display auto-switches from one to the other. Would be nice to retain this functionality.
And last but not least, anywhere in HK to order such a device online?
