"It appears my current set up is hdmi connected to a splitter then to Sky HD and PS3
Sky HD is connected to the DVI"
I think, Sky HD and PS3 are connected to a HDMI switcher which is connected to DVI-I input....(?), so you can choose between Sky and PS3 on the DVI input, am I right? Because a splitter connected to an input doesn`t make sense.
"if you connect it to VGA would you not lose the HD quality ?"
No. You have to connect to the VGA out - it`s labeled "PROJECTOR" - because this output will be activated by pressing FORMAT - 0.
"If I have to use VGA connection then I will have to get a long lead as my projector is on a ceiling mount."
Yes. I had 10 metres and it worked fine.
"Do you have IR connected to control the projector via BEO4"
Yes. I`m using a Lintronic box for the projector, the screen, lights, blinds...
