Eye sight and perception are funny things and some people are affected, others are not.
If you are affected like me or my wife, it can not only cause video artifacts but eye strain, head aches, and even motion sickness.
If you are going to spend your hard earned money, a good watch might be prudent. I too was sold technically on DLP, and it does have its advantages, but it just was not for us.
Now if I could afford a 3 chip design,than this discussion would be mute.
