    Does anyone know if you will be able to use a Playstation 3 with a DVI input monitor using a HDMI to DVI cable?

    Is there any picture quality difference with a HDMI to DVI connection as opposed to HDMI to HDMI?

    No. The digital video signal is the same for both. HDMI just has audio whereas DVI is video only.

    My concern would be HDCP encryption. Am unsure if the PS3 has HDCP enabled on its HDMI out. If it does then your DVI compliant monitor would have to support HDCP to view the PS3 output.

    I would expect that you would need HDCP support on your DVI display (which does exist on some - but not many) to replay BluRay movies on your PS3.

    It MAY be that you don't need HDCP support for gaming though.

    HDMI to DVI swith and/or tv with DVI input is not necessarliy the same as HDMI to tv HDMI input, even if you take the audiopart of it out of the equation. rthis depends on your tvs processing capability and if it can accept digital component colourspace iver HDMI.

    DVI is a subset of HDMI, and only support 8 bit 4:4:4 RGB colourspace

    Conecting a HDMI source to a DVI sink will force the source to output RGB.

    The HDMI spec also support on top of this 10 bit Component colour space.
    This also happens to match the colourspace that DVD and blu-ray use.

    The upshot is that (and this depends if you tv can accept component colour space on HDMI as I said) that a HDMI-HDMI link may well sport les colour conversions along the way leading to a possilby better picture - less chance of colour banding etc.

    My Sony nS76 can do either component and RGB through HDMI to DVI on my PJ. I also got the same thing from a Panasonic S52. I currently have the sony on component.

    Err - DVD and HD-DVD/BluRay are 8 bit 4:2:0 YCrCb colourspace on-disc AIUI - though BluRay MAY optionally include 10 and 12 bit support, as well as 4:2:2 support, for suitably mastered discs (aimed at more professional applications of the format)

    My understanding is that HDMI versions prior to 1.3 only support 4:4:4 RGB and YCrCb at 8 bit, but also optionally there is support for 10 or 12 bit 4:2:2 YCrCb (the bits you gain by reducing the chroma sampling rate can be re-assigned to greater bit depths) AIUI HDMI 1.3 now supports 4:4:4 YCrCb at 10 and 12 bit depths?

    I think DVI only HAS to support 4:4:4 8 bit RGB to be compliant - but that doesn't mean YCrCb can't be used optionally ? My understanding is that the source will feed what the display asks for if it can - i.e. if you have a 4:4:4 8 bit RGB display it is likely to be OK - as RGB 4:4:4 8bit is a minimum spec for any display? Of course the issue is that most HD Video - apart from games - doesn't start as 4:4:4 or RGB. Most video is delivered as 4:2:0 YCrCb so needs to be chroma upsampled and matrixed to RGB - and converting YCrCb to RGB can be done wrong...

    DVD is (mainly) ITU 601 and HD-DVD/BluRay is (mainly) ITU 709 in colourspace terms. This means the YCrCb->RGB matrix values are very different for the two systems (for ITU 601 Y=0.59G+0.30R+0.11B, whereas for ITU 709 Y=0.71G+0.22R+0.07B, a big difference, and very important to get right...)
