Thanks!
Good to know. Hmmmm. Now which two members should I ignore in the RS1 threads??? (any suggestions? )

Tom, thanks for the info, that's enough for me to go on.

"Click on the member profile for the person you want to ignore. Choose "add to ignore list"."

I only get the choice to add a person to my Buddy list.

I did it by selecting User CP at the left of the horizontal bar near the top of the page, then Buddy / Ignore Lists is toward the lower left.

Hi!

Please! Somebody knows if it accepts HDMI 1.3

Thanks!

The RS1/HD1 is HDMI 1.2. HDMI is backward compatible for connection to HDMI 1.2 devices. Clearly you won't get any additional 1.3 video featues what ever these may be in reality.

HDMI 1.3 spec has

48-bit color depth

Dolby TrueHD and DTS-HD Master audio.

How does the 48-bit color depth work with existing DVD, HD-DVD and BD ?

No existing video format supports 48-bit color depth, and the projector wouldn't be processing the audio anyway. HDMI 1.3 is not needed in the projector.

The 10 bit color extension would be useful even without extended gamut because even the traditional gamut would have more color resolution - i.e. more in-between shades for existing the color spaces. This makes the use of external processors for shading, grayscale and color tweaking more usable without compromising performance.

Using external processors with 8 bit color inputs limits what you can do without causing crushing, which is why it is usually preferable to achieve calibration using the device alone. With 10 bit color (and higher) I can actually see using external processors to finish tweaking the calibration in cases where projector's limited built in calibration tools leave off with a less than perfect result.

I do think that for existing sources no use should be made of the extended color gamut - it would just lead to oversaturated and inaccurate colors - although there may be people who enjoy this. Perhaps video games or some proprietary new titles in the future will support "deep color" but there's no mention of it in the BR and HD-DVD specs.

Finally, if projectors are tweaked to provide maximum contrast at an extended color gamut, when you constrain the gamut for existing color spaces and source materials, you would be losing brightness and most likely contrast.

Thank you. Every time I hear people talk about this I think to myself that unless all the sources and components are in sync the wider gamut would just cause wrong (i.e. oversaturated) colors. So it seems I am not alone in thinking this.

Where are those in-between shades going to come from?

Besides, a good display doesn't suffer from banding.

If an image, which only has 8 bit color, is scaled up, the output of the filtering calculations will have more then 8 bits of precision.

As an illustration, imagine that there are two adjacent pixels, one with the value 0, and another with the value 1. This two pixel image is scale dup horizontally by a factor of 2. The simplest linear filter that you could use would yield 0.5 for the pixel half way between them. i.e., there are now more fractional bits worth displaying then there were in the original output.

Even without scaling, the output of a decompression algorithm can yield more bits than the original input, as can any adjustments such as brightness, contrast, etc.

There are simply more shades of color WITHIN the existing (old) gamut that the device accepts as input. Again, the only place I think this makes sense is when using an external device to do processing because of inadequacies of a projector - for example the inability to edit LUTs. I agree with you good display devices shouldnt display banding, but I also see people talking about using external processors to do color / gamma adjustments. This can lead to banding regardless of the quality of your display if it is limited to 8 bit / color digital input.
