Any particular reason for going with the 'High Power 2.4' screen. Unless there is some very specific reason that you have for wanting a 'High Power' screen, my recommendation for your projector would be a 'Matte White' 110" Model C # 94364 screen.
?
i researched a lot before deciding on the screen. I was all set to get a matt white and then i came across these 2 threads...

Da-Lite Screen Material Review - Home Theater Forum and Systems - HomeTheaterShack.com
In summary the benefits of the Da-lite High Power Screen are....
1. Gives a robust high brightness image with real to life colors and whites
2. Provides greater perceived contrast
3. Has a clean uniform image so that the surface completely disappears
4. Has no hotspotting or visable waves
5. Has an amazing ability to shed ambient light
And the 2 most important benefits....
6. The High Power screen is less susceptible to waves which all other screens develop ( sometimes in 2 months or sometimes in a year... )
7. The High Power is a high gain screen with 2.4 gain. As a result the image is super bright. This lets you run your projector in a lesser bright mode/eco mode or just in general reduce the various brightness/contrast settings to much lower value as compared to if you were projecting on a matt white screen. This results in a much longer and increased "Bulb Life".
I wanted to test the first 5 points myself so i got samples from Da-lite. they sent me all their screen types which are listed in the following link....
Selecting the Right Screen
I bought large chart paper and stuck these samples to it side by side and put them on the wall and projected various material on them. I tested the High Power, Matte white, High Contrast Matt White, Silver Matte, Video Spectra, Pearlescent & High Contrast Cinema Vision.
I tested them in Ambient light and then in Total Darkness. I tried to re-create all the test conditions in the above links to the best of my ability.
The High Power sample was just simply 10 times brighter with better contrast and superb colors than all the other samples.
All the other samples looked washed out and faded in comparison to the High Power. I was an instant fan and i decided to get it.
Now there are some limitations to the Da-lite High Power....
1. Since the High Power is Retro-reflective in nature the projector needs to be on the same horizontal viewing plane of the viewers. So basically it means with you table mount the projector or the other option is to hang it from the ceiling and drop it as low as possible to the level of the viewers head.
So it's more practical for a dedicated HT room where the projector can be table mounted in front or behind the viewers on a shelf at a permanent place but this is not possible/practical in a living room.
Since my setup is in a living room i needed a workaround.
So my work around for this was to get a projector mount with an extension bringing it down to about 35 inches from a 9 feet ceiling ( 113 inches ) This allows the projector to be high enough in living hall so that no one accidently walks into it.
According to the High Power Gain calculator ( Post # 566 ) this would give me a gain of 1.59 which is still below the 2.4 potential of this screen but is still better then the 1.0 of a matt white screen.

And in the future if i have a dedicated room for the HT then i can do the perfectly ideal placement for the projector and get the entire 2.4 gain.
2. The gain/brightness tends to drop as you move too far away from the center towards the left and the right of the screen.
Basically it means that this screen will behave like a 1.0 gain matt white screen if you look at it from the edges. Now far on the edges is variable to the screen size vs distance vs. projector placement.
So all in all in it's price range this is the Best Screen out there if..... you can place the Projector ideally to get it's 2.4 gain or as much gain below 2.4 as you can with a little compromise on the projector placement....!!!
