I checked both Optoma P1, LG HU85LA, but since 明基 is just released, so I posted for one more choice.
Personally... I don't like all three of them, first only 120 inch; second the lag is too large , around 49 to 69ms, which means for gaming it is impossible (gaming best is around 20ms like those Sony); thirdly, all of them are way over-priced, the machine only worth around 10k... it is just my personal opinions
LG HU85LA uses three lasers means rainbow effect should be non-existence.
