Combo Scalers and Projectors

Is there anyone besides DWIN that sells a complete front projector solution where the projector is physically separate from the image scaler? This makes a lot of sense. The scaler box can be next to the AVR, etc. and the projector can be at some distance from all the other electronics.

SIM2 comes to mind; the LINK version of their projectors all come with an outboard processor (the DigiOptic Image Processor, or DOIP) that works very well in my experience. It uses the Faroudja processing chipset.

Optoma also has a combination package of the HD-80 with their HD-3000 scaler that they call the HD-803 (I think that's the name.)

Frankly, the scalers inside most new projectors are VERY good a going from 1080i to 1080P. The problems for internal scalers are the 720P and legacy devices with 480i going up to 1080P.

The other problem with HDMI connections (which is what we are saddled with now) is that by the time you run from your source to your AVR to your scaler to your projector you've got WAY to many chances for handshaking and signal loss issues to effect picture quality and ergonomic execution.

I've come to REALLY despise HDMI...

:evil:

I'm not a big fan of HDMI either.
The handshaking between units causes far too many problems (I literally have to power down when I get the dreaded "static" screen).

Besides the convenience, does HDMI offer ANY advantage over component connections?

Thanks,

Yes, HDMI does offer one serious advantage - it is a completely digital signal stream. Component requires D/A at the front and A/D at the receiving end. This conversion process is no more transparent in the video domain than it is in audio.

DVI offers the same advantage, but is seen as yesterday's technology so few new units support it anymore. Too bad. It was far more physically robust.
