Ceiling mount vava 4K

I am looking for a ceiling mount for my VAVA 4K on 150 inch ALR screen. Can some one please let me know the ceiling mount I should buy and what should be the height and distance from screen to have mount for 150 inch projection? I have a wall of 90 inch excluding the box around the ceiling. Can I even get 150 inch projection if I go for celing mount?

I have same question. I am trying to mount VAVA chroma using the universal ceiling mount but looks like I am not getting complete screen (it should be 108 width and 59 inch height)
