Hello,

I want to create a DIY stand for a 150 inch projector screen with grommets.

I want to achieve a nice smooth, tight stretched final screen like the below:

I want to avoid the sag etc. like the below:

Any advice? Use velcro straps to attach the screen to the stand or plastic cable ties?

Also, per the grommets on the left and right vertical poles of the stand, obviously gravity would want the velcro strap to slide downwards and not stay in position. What do you suggest? Use some tape to stick the velcro in position on the pole so it stays in one position?

Many thanks!

Some questions:

1. What is a good distance to keep from the screen to the frame for the entire perimeter?

2. Can drilling split the PVC rendering it unusable or would drilling give a nice smooth hole? I like the bolt and nut idea to keep the vertical tiedowns in place.

3. Can you point me to an equivalent link on amazon or ebay for the bungee cords?

4. What is a recommended [maybe a popular choice] PVC pipe size for 150 inch projector screen frames? 1/2 inch, 3/4 inch, 1 inch?

Lastly, I need your help with a calculation please.

Screen size - 150 inch diagonal (16:9)

Projector model: Optoma HD200X-LV (Full HD 1080p). Projector ceiling mounted at the back of the room.

Calculation: if I want to fill the entire screen space of 150 inch diagonal, what is the MINIMUM distance that I can have between the screen and the projector lens? I am asking this question because the room that I have is a bit small but still large somewhat, and I would like to be able to fill the entire projector screen.
