Just wanted to ask you how certain you are that, and to what extent, your replacement HCHP screen from Da-Lite is free of texture? Is it just 'mostly OK', or is it really completely clean? No lines/banding anywhere?
Often I'll find on these screens that if I stick up one of those sample Da-Lite screen patches (that have one-line of sticky tape on the back), and pull it off, that sticky area will pull off a bunch of the dirt-- the result being you'll have one small rectangle, of the same size/shape as the sticky area on the back of the sample patch, that's now brighter than the rest of the screen!
I should also report back on my Draper experience: it was extremely poor. The screen was at least as bad as, if not worse than, the Da-Lite HCHP screen. Banding/striations everywhere, dirty, etc. On top of that, it was ridiculous to assemble those tension rods! I hurt my hand & cut my finger :-P However, on the bright side, the tension rod system ensures no ripples
. So at least they got that right, despite it being ridiculously difficult to assemble. Da-Lite's snaps are much easier, but, as I mentioned earlier, I got some ripples due to uneven tension.
Below is a video that'll hopefully help you see what the banding/texture looks like. I embedded some red arrows in the video here & there to point out banding; however, by no means are those arrows comprehensive. You should be able to find even more patterns/banding. The banding looks worse in real-life than in this video, but, again, is mostly only visible with low contrast or bright content, with smooth on-screen content. Here's the video:
I'm returning the Draper b/c they didn't even seem willing to QC a screen before shipping it to me. Da-Lite seemed more willing to work with me/my dealer (David Nash over at www.thefinalflick.com
: fantastic & helpful, by the way). So I'm getting the whole HCHP screen/frame replaced (latter b/c of the ripples; maybe button were not optimally aligned). Also, trying to constantly swap out the material on the Draper would be a nightmare b/c of the extremely difficult assembly process. Given my experience, I simply cannot recommend the Draper Contrast Radiant screen, despite its superior tensioning system.
If after 2-3 more tries with HCHP, I may just go for the HP material, as there appear to be relatively fewer complaints. I wonder, though, if that's because this banding/dirtiness was a quality control problem with the beads at the factory? If dirty beads show up every now & then and get sprayed onto the surface, the material that gets sold more may have these dirty beaded screens 'diluted' simply b/c of volume of production... who knows. I have no idea what the actual problem is, so, it's anyone's guess.
I do wish that someone at Da-Lite/Draper would investigate this issue though.
