Hi, I'm currently in the same boat, and I'm a bit lost with the 3d support. I was going to buy the acer k330 because it has audio out for £380 uk amazon, but it seems it only accepts a 4:3 3d picture from vga at 1024/768, and its not supported by any of the 3d converter boxes. This will be my first projector, and I'm looking to to use a 120" screen. I understand this 500 lumens isn't enough for 120" 3d screen, so I'd probably down scale to 60-80" for 3d content. I plan on keeping it for a few years, maybe pick up a converter box second hand or while on sale. I'm not in a hurry to set up 3d but I would like it as an option in the near future. Do I have to choose between having audio out or 16/9 720p 3d support? If a newer 3d converter box was released that syncs with the acer k330 would that allow 16/9 720p 3d, or are they hardware/firmware limited? I read that someone got 3d with the acer using HD fury, and the dvi pin hack, but i am not sure if it was 16:9 720p or just 4:3 1024/768.
Help my brain hurts!
