When looking at the 117 point cross pattern, my green line is shifted below the white reference line at the top of my screen. It is very noticeable across the top 2 or 3 white reference lines. It appears shifted down and slightly to the right. The calibration tool only allows calibration of blue and red. I am told that the green can be adjusted manually. I have never opened this set up before. Can anyone confirm if this can be adjusted manually by opening the set up? Also what do I do? I looked at a reference manual that some one else posted on this site in another thread, but it is for a ceiling mounted projector. I don't imagine it is much different of an operation, but was looking for some help specific to this set.
