I guess I'm in the same boat as darthjoe above. I wanted to use the VGA as well to get the upscaling of my SD-DVD's and to also get the 1080p output signal so that's why I ran out and got the 360 VGA cable. I never even got as far as ever putting in a SD-DVD, because via the VGA cable on the 360, my HD-DVD's now looked plenty worse (softer, washed out) then what I was getting via component; so I gave up on it and went back to component and 1080i.
I guess one could use a switcher-box of some sort to get the benefits of both (i.e. use component for HD-DVD and VGA for regular def) but that would be a pain with all the different configurations you would have to make on the 360 and your display everytime you switch back and forth.
Anyhow, wondering if anyone can answer my neophyte question from the last page here please, at this point I'm so confused about resolutions I don't even know what I have!!!!!!!!
Thanks for the help here guys in getting me set up the best way possible.
Here are my Sony HS51a projectors stats:
720p, 1080i, 1080p
Component Video: Yes
Digital Input: HDMI (HDCP)
Personal Computers: Yes
0.7" PolySi LCD (3)
Native: 1280x720 Pixels
Maximum: 1280x768 Pixels WXGA
Aspect Ratio: 16:9 (HD)
That said, would the 1080i component setting on the 360 be the best way to go "in theory" anyway versus the RGB input? Or should I maybe even try 720p via component as a better fit for this projector? I guess I'm a bit confused by the "Compatibility" stats listed above and the fact it lists 1080p as being on there. I somehow had it in my head that, "hey, I've got a 1080p display!" I don't think that's the case now.....
On another note, Would this projector benefit in any way being fed a 1080p signal down the road with, say, a true 1080p output from an HD-DVD player, or am I crippled by my max resolution listed above at 1280x768 and be better off playing it 1080i or 720p for all-times sake?
