Hi Raghav / others,
I am also trying to explore the possibility of installing a PJ in my living hall, it was constructed a few years back so I have to keep the room limitations in mind and plan for PJ accordingly.
I had seen HD20 at Raghav's place and I liked it

but due to its lesser flexibility interms of placement trying to see if I can use this in my room or i need to necessarily look at the LCD projector :sad:
Now my limitations are :
1) I will have to ceiling mount it in the iron angle ( meant for fan) - not sure if there are any ready made PJ mounts that can be hung in those angles meant for fans or i will have to get some alteration done or a custom made PJ mount built
2) As suggested by Raghav above "the distance of projector from screen should be between 11'7" and 13'11" and 13'11" would be better choice" However I will have to place the PJ at the distance of 10.5 - 11 ft - Now it ok? and will it just reduce the image size of the PJ or it impacts the PQ as well if the PJ is mount at the distance other than 11'7" and 13'11" ?
3) I wont be able to ceiling mount the PJ screen, are there any screen mounts available in the market by which we can wall mount the screen from the sides ? ( I don't have option to wall mount the screen on front wall and will have to mount it on the side walls)
Regards,
Naren
