Some people when watching dlp can see a rainbow effect when watching films and 720p is hd ready....1024 x 768
Lcd does not suffer from the rainbow effect and the lcd that your looking at is1080p is full hd 1920 x1080 full screen res.
What is the model of the projector that your looking at?
I use a Jvc HD1 1080p on a Bv7-40MKIII
