How to set up a Ruby properly

780 Views 4 Replies 4 Participants Last post by  rabident,

Once upon a time a chap called Guy Kuo posted an exellent thread entitled "Holy Focus". Im sure must members that have had a CRT have read it and achieved excellent results by adopting the techniques described, even novices, I know I did.


With so many positive and some negative views on the Ruby it seems that set up especially for black level is of paramount importance. I think it would be very usefull for someone like Darin to post a guide to the perfect set up by using basic principles to include techniques and measuring equipment used to give the optimum image.


Maybe this can happen once the service adjustments have been fully explored.


At least we would get closer to comparing like for like.

I think that would be a great idea, seeing as there has been very little definitive info along these lines here (esp. lately).


The Ruby has some unique features, and I, for one, am having some difficulty in determining just what affects what else, and how best to set up the black / white levels in the Auto iris mode.

Would it be possible to take a picture of what is actually being projected when the PJ is fed a full field black signal, then invert the colors while keeping the intensity (opacity) the same and print it to a transparency as a custom color correction filter?

That would ruin your uniformity for white though.

Do the black level uniformity problems not show up on a white field as well? My D-ILA has color uniformity issues across the board (black, white, and especially visible on solid yellow fields).
