In this case you have to use dual-link DVI (or DP?, I am not sure of this) and you will bypass the receiver at all, hence you don't have to worry about the compatibility of your receiver (even a HDMI 1.3 receiver is enough; use the extended desktop mode, one for the projector via DVI, the other for the receiver via HDMI).
It is another issue if 1080p 3D projectors with dual-link DVI will be released. AFAIK
SHARP XV-Z17000 is the only 3D projector released in the next year having DVI ports (dual-link?).
Hi renethx and thx 4 the reply!
When building a HTPC, I build it in the knowledge that a future upgrade is always a possibility but in contrast to other devices, you don't have to replace the entire thing all the time. So if a new graph card comes out with HDMI 1.5 so to speak, the cost of upgrading is negligible compared to having to upgrade a receiver or PJ...
In this particular case my problem would be with the receiver since it is what I would buy before a PJ. Seeing as how I have to spread my purchases, the PJ would come last and if by that time it were to support FullHD 3D@60Hz/eye I wouldn't mind replacing the graph card but the receiver on the other hand...... :-S
That being said, I don't really see anything of the sort on the horizon in the relatively short to midlong term PJ-wise, so you are right and I might as well take the jump now.
It's not as if 3D 720p@60Hz/eye will be a bad thing compared to 3D 1080p@60Hz/eye either
With regards to DP, the latest 1.2 version does enable FullHD 3D streams @ 120Hz and the HD6870 is equipped with two of those
The standard does lack native support for the xvYCC color space though...
If a PJ with a DP1.2 connection or Dual-link DVI should by some miracle happen to come out in the not too distant future, you raise another valid point worthy of consideration that I might as wel buy one of last years receivers with HDMI1.3 (no need to upgrade the graph card or the receiver anymore either. Unless ofcourse by that time there are receivers with DP connectors but I highly doubt that)... hmmmm.. food for thought...
