The post was buried down in this thread
about HTPC timings on the D-ILA. Here is is again, touched up a bit to make it readable (it was spread across multiple posts):
If you plan on using an HTPC and getting HDTV *not* through the HTPC, you should connect:
- HTPC on Computer1
- HDTV on Computer2
The Computer2 input is the most versatile input on the D-ILA (grab your manual and turn to the "Available Inputs" page...Computer2 is the only one that accepts every single type
of source material!).
You should save this input for your most-demanding component, if possible. Since a VGA cable works great in Computer1, and since Computer1 accepts all of the computer formats but none of the video formats, you should use that instead of Computer2 for your HTPC.
Once you can run HDTV through your HTPC (with a HDTV card when they become available), the output is not going to be HDTV anymore, but scaled to SXGA. I would expect the projector to auto-sync to the "SXGA3" signal. As a side note...where ARE
those HDTV cards anyway? http://www.avsforum.com/ubb/biggrin.gif
This means that you would still want to use Computer1 for the HTPC, as the HDTV signal would now be a computer-based one, and not seen as an HDTV video signal. Similar to running an NTSC TV signal through a TV tuner card...the projector isn't going to see it as an NTSC signal with a 480i resolution anymore but a computer signal with the resolution that you are currently running on your graphics card (probably 1365x1024).
This makes sense to anyone playing DVDs on their HTPC. The projector doesn't see a "DVD player" with a video output, but a "computer" with a computer-based output. It is the same with TV tuner cards and will be the same with the HDTV cards when they become available.
The Computer2 input is great because it handle BOTH the video signals and the computer signals. However, it really excels in the former, being the highest res., video input that exists on the projector. Forget that it's called Computer2...Call it "HDTV1"! Or even, "DTC100".
Another way to look at it-->you have 2 high-resolution capable inputs:
COMPUTER1: Accepts computer signals to SXGA3 (1365x1024)
COMPUTER2: Accepts computer signals to SXGA3 and video signals up to HDTV resolution.
If you are only feeding the projector computer-based signals, feed them through Computer1 and consider Computer2 your "HDTV input". The cabling is easier (VGA-->VGA), and you save that versatile Computer2 for when you really need it!
The only exception would be if you have 2 computer-based inputs, then you have no choice but to use Computer2 as a computer input instead of a high-res. video input.
