I have been recommended "Snowfield" in Glidden paint, but was told that "veil" may work as well, though in THX mode with some hours on the lamp it might get dark, but it's possible to run the pj at normal instead of the ECO when running THX isnt it?
Yes....but the end result skewers the desired THX parameters a bit. It's always been better to have extra lumen output and be able to attenuate down to a desired state than to try to "grow Lumens" where none exist.
I will be using it at times with ambient light, so i will definitely go with a grey screen. And I am over sensitive to specks/grain in screens so it needs to be a flat smooth color. The likes of Black Diamond and other gain screens drive me crazy.
So to summarize: throw distance 12ft, ceiling height 8' 2", looking at a 90-100" screen in 16:9. Need it to work with ambient light at times. Most of the movie watching will be in fairly dark environment but with white ceiling and walls. Eventually I will block the side walls with curtains leaving only ceiling and back wall (pj) in white.
I'm looking to build the screen from 1/4" MDF and mount with a large plasma wall mount.
Looking forward to hearing your thoughts.
Well first off, MDF is a "I have to use it, I have no other choice" selection. That would mostly center around both cost and effort considerations. But the truths are very well known,
1. BOTH sides of 1/4" Mdf must be sealed with two coats of Primer (Rolled) or 3 coats (Sprayed) to prevent bowing unless Mdf is "Frame Mounted", and then....it just keeps getting heavier and heavier....
2. The variable porosity of a Mdf surface require pre-sanding...cleaning...priming / sanding / priming to be ready to hopefully receive a finish coat that is truly smooth. (non-viewing side needs only priming)
Now done right, yes...the Mdf can be very serviceable. But it's sooooo heavy! and if your to attempt to attach it to a wall via a conventional "Dual Arm" Plasma Wall Mount, the "Screen Mdf" will have to be backed by a thicker material, either glued on 1x
lumber slats or a securely glued 4' x 4' x 3/4" "plywood pad" located at center.
Ya gotta be told...it would be far better to rip a French Cleat hanger, using 1 x 6
lumber. A long length of such can double as a "Stiffener" as well.
Personally, I'd suggest Sintra...a material designed to be painted upon, mounted upon a frame of 1" x 6" poplar Lumber. Lighter, ready to receive paint....it's really highly preferred although it's expense does add to the cost of a good DIY effort.
Paint-wise....I'll get back to that soon......
