Greetings David in Cambridge.

You will be removed from the forums if you continue this nonsense of addressing another member with silly names after he has very nicely asked you to use his proper name. Judging by your picture you are a few decades too old to be acting so immature.

Well coming back to the topic again!

Things that I tried and noticed:

Removed Heat Filter to check luminance output and increases significanly but not acceptaple (reinstalled the heat filter back).
The mirror in the lamphouse is the 270mm standard mirror and not cold light mirror.
The distance between the screen and the projector is 25 meters. Screen size is 12.6 x 6.6 from the early 90's. I believe is Matt White.
