As mentioned in my previous post, the colours in our projection were not very accurate - highlights washed out and so on. Changed the modes on the projector and viewed the blu ray movie which came along with the projector. With that movie, the modes sRGB, movie, presentation and bright all looked similar. But with our Darshan video, movie seemed a bit too reddish, with a slight excess of brightness over contrast. Presentation looked better, so currently have set it to presentation.
