So reading the above posts regarding 'Shelf Mount' brings me to my own question.
Below is my seating. Behind the couch you can see a tall shelf on top of which is my current Epson 5010, which projects on a wall right in front of the couch.
The Screen is exactly 150" diagonal, and that Epson 5010 is sitting exactly 15.1' from the screen. You can see the floor in that photo, and the screen is about 2 feet above the floor, just to give an idea of how low the screen goes.
The Epson clears our heads completely and reaches the bottom border of the screen with no issues.
Is the BenQ HT3550 going to work sitting exactly where the Epson 5010 is?
Will the distance from screen provide enough room for 150" and will the light output be sufficient for UHD HDR?
