    Hi all

    I'm just about to start putting this HCPC idea into practice so I hope that these are the last of my silly questions:

    1. If I use a Radeon VE card and PowerDVD using VGA out to my PJ am I getting a progressive signal. If I'm not, what do I need (hardware/software) to get a progressive signal?

    2. My PJ does not have a 16:9 mode when using the VGA in, but I can change the aspect ratio to 16:9 in PowerDVd. Am I not getting the benefit of the extra resolution of annamorphic DVDs. I can't see any loss of detail myself.

    Thanks in advance

    From what I gather from previous posts, VGA is inherently progressive scan. The PC draws 640 x 480 or 800 x 600 etx at the same time, ie progressive scan. I believe this is also the same as a line doubler. After that I get kind of lost so I will leave it to the experts.:clown:

    The basics of progressive scan are covered at www.progressivescan.co.uk.
    Yes, the output of the PC is progressive scan.
    72Hz if the refresh rate to aim for.
    If you can't reduce the vertical height of your picture and save it as a separate memory 'block' then in order to be able to watch 4:3 and anamorphic material, you will need to 'lock aspect ratio' in the software and use a 4:3 setup.
    Yes you are losing data but if you can't tell any difference then fine :)
