I apologize if this is too long/detailed, but I like to be thorough ;-)

New around here - 2nd year medical student needing some technical help ;-) I've been researching this for about 9 hours, and the internet isn't yielding any answer-bearing fruit(s)...

I have a 60g 1st gen PS3, and a HP MP2210 projector. This projector is exceedingly hard to find help for...HP's site/manuals/troubleshooting leaves a lot to be desired, and I've looked on not less than 35 AV/PS3/Projector forums - people here seem to be the most informed, so here I am [cursed by usefulness, y'all are...flattery never hurts :-) ] Apparently I don't have enough posts to paste legitimate links yet...so just copy & paste these hoes

The projector's manual (and the 2nd link above) says it accepts 480i/p, 575i/p, 720p, 1080i HDTV inputs (manual also says it accepts 1080p)
It has VGA, S-Video, and composite input, and it's native display is 1024x768 (4:3) I have verified that the both the projector and PS3 are running their latest firmware versions (1.2w & 3.01, respectively)



These are connected via:
AV multi-out to VGA cable (appears to have a transcoder)
Link: mayflash.com/vgabox/vga004/vga004.htm
The cable info says it is compatible with 480P/720P/1080I/1080P when used with the PS3 game console, with frequency 50/60/75HZ



Now, for the issue...

I can only get the setup to work in 2 modes over VGA, 480p and 1080i. 1080i works great - the XMB and any videos I play over the media server are shown properly, and games that support 1080i look fabulous...but 720p games are being downscaled to 480p, which blows. DVDs are also only being displayed in 480p, but this is not as large an issue as the game-stuff.

If I set the PS3 to display in either 720p or 1080p, the projector does not detect the video signal, and displays the message "Out of Range" after scanning the VGA input for 5-10 secs.

I'm assuming this message has something to do with either the refresh rates, aspect ratio, or horizontal/vertical offsets - but I am having little/no luck finding how to adjust these rates on either the projector or PS3, and I've been lookin for about 8 hours.

Any ideas? The projector has an option for widescreen input (on/off), but changing it does not alter any of the above behavior (1080i still works, 720p/1080p don't).

I find all of this extremely odd because the projector's manual states "if possible, select progressive format when hooking up a video source" WTF?

My only thought is that maybe the cable's transcoder-majig is changing the progressive output(s) into something that the projector doesn't recognize? As far as I can tell, AV multi-out to VGA is my only option other than AV multi-out to component cable (from PS3) coupled with a component-to-vga cable (to projector)...which I'm assuming will yield unfortunately similar results :-/ If anyone can state with certainty whether this true (or more importantly, not!) that'd be, like, super.

Thanks in advance,
