    The Operating Instructions for the Sony VPH-D50QM CRT projector include in its spec:-
    Resolution: 1280 x 1024 pixels / 1000 lines (HDTV input).
    Input A refers to a HDTV component input and a GBR (whatever that is!)
    I already have this projector operating with its line doubler board (EXB-DS10) on standard DVD component input from a DVD player and S-Video from a surround sound processor for all other sources; since 1999 in fact (who needs HDTV?).
    My question is : does anyone know if this projector will display HDTV signals as produced from Blu-Ray DVDs/HD-DVDs/Sky HDTV transmissions without any further processing and if so how will it need to be connected to the HDTV source in order to do this?

    Yes it will display HDTV
    Most of the sources you mentioned will have a digital output but you can bet pressure will be on to have analouge outputs too. The Analoge will be either Component with the Sync signals on the Y cable or RGB with Horizontal and vertical syncs.
    If you are laying cables allow for the five wire, but my guess woul have to be component 3 wire

    Thanks, Roland. I already have a component lead installed. For HD would I need to make any adjustments to the projector other than select Input-A as I currently do to select the component input? What about the line doubler - would I need to switch that off?

    You'd need to disable doubler. I'd look at getting an external scaler anyway as the doubler board in the Sony is really not that clever compared to what is available these days.

    If I recall you can only do 480/576p through the internal doubler..It will certainly display HD via RGBHV and though theres a possibility that component hidef outputs may be on HD DVD and SKY ..it is pretty certain that they will have either dvi/hdmi(hdcp) outputs.
    The idea will be input into a scaler via DVI/HDMI and output defeating the hdcp before you go into the crt RGBHV.

    Just as a side note: convertor boxes are now available to allow a hi-def HDMI/DVI digital signal to be connected to an analogue RGBHV input on a CRT projector. They even handle HDCP encrypted signals.

    Sim2 UK have one for about £295 that is guaranteed HDCP compliant.

    Joe Fernand at The Media Factory has another for approx $400, though I'm not sure if it is HDCP compliant as well. :)

    Thank you all for your replies. They give me encouragement to pursue the idea when HD is finally realised in the UK.

    Really? :thumbsup:

    I must admit I thought that they'd be a law stopping this. Not that I'm complaining though :)

    A moderator of great integrity..................

    If the HDCP stripper / convertor boxes are integrated into a projector as a modification or retrofit, then surely no-one should get upset? The end result would be the same as if the PJ had been fitted with an HDMI input in the first place, and there was no component or RGB output for, er, non-display devices.

    A self-contained convertor box, though, is a different thing altogether........

    I think we all knew they were going to happen, though.
