Thanks Sushi. I did not know that DaLite custom masks for customers. Thats excellent information. When time comes definitely will go that direction. Since the X1 is a 4:3 projector there is definitely not so black bars below and above which accounts for about 8" so I defitely will measure how thick those bars are and match it to the sides. What is the diff between the model B and model C?
