Hi -
I am in the process of ordering parts to start the building of the projector.
Something that is not clear to me is - If I need to send component or HDMI input into the lcd when in the projector - how do I do that ?
Any advise or if somebody could point me to the appropriate links - I would highly appreciate it - Thanks in advance.

I use the Vdigi VD-Z3 to switch between VGA and componetn inputs. It is a Component -> VGA Transcoder

If the Lcd supports sync on green then you can use a vga-to-component adapter.
