Lets be clear on one thing here.
Obtaining the "Better'n a Plasma" look has always been first and foremost in every DIY offering I've been involved with since 2003. It gets considerably harder to maintain that level of PQ when there is ambient light of any degree present, but proportionately, you don't see many 100"+ Plasmas featured on AVS or offered up for comparison.
Performance in a DIY Screen is based strictly upon planning and effort...and to some degree (...but less than Mfg...) expense outlaid.
A Mfg Screen like the featured HP works splendidly for many apps, especially those whose rooms are more narrow than wide, and whose lighting directly ahead of the Screen area is controlled.The DIY application shown is Silver Fire, something that combines a small degree of retro-reflectivity with adequate sideways disbursement of reflected light as well.
In other words, it has a narrower viewing cone than a 1.0 gain Matte White, but not much less. You don't see side shots of HP screens like the ones above, nor nearly as many shots in high ambient light either.When combined with the known ambient light resistance of a Gray base color, the enhanced reflectivity/brightness provides much better ambient light performance.
This is something decidedly lacking in a HP screen, although in many cases, sheer directed brightness does compensate to a degree when and if there is good contrast specifications added into the projector equation. Simply put, the better the blacks are starting out, and the more intensely they are presented onto a surface, the less impact ambient light will have on them. Yessir, there will still be a degree of "washout", but in many cases, an acceptable amount.
Simply put, a HP screen getting hit with a Uber-High Contrast PJ's image is gonna look spectacular....brook no doubt. Ask any JVC owner w/a HP.
Then again, I haven't seen many 160" diagonal HP's on the Boards.
In contrast, Silver Fire, and it's stable mate RS-MaxxMudd both have shown considerable use in screens at/above those sizes. Both exhibit gains of 1.2+ yet appear to be much higher when a good PJ with high contrast combines with those Screen's higher reflectivity and contrast enhancement characteristics. Just like what happens with a HP. Go figure.
All such Screens, DIY or Mfg are Passive, the differences lie in how the light is redirected, attenuated, and or shifted (ugh). Light focused within a narrower cone of incidence is not just gonna seem brighter...it will be / is brighter. That is due to an increase in intensity via density related amplification. No extra light is produced, just concentrated.
Therein lies the premise behind the designs of the HPs, the Black Diamonds, the Fire Hawks, and yes, the Silver Fires of this existence. Some applications can and do do more, and/or do things better than others. Cost alone is not a good basis of judgment to use to make a choice by as to performance/value considerations .
This little dissertation is not / was not intended to promote DIY over Mfg. Both venues offer specific advantages, some "over" and some in concert with the other. In my way of thinking, the primary advantage of DIY is extreme flexibility in design, and performance levels. When combined with the "almost always the case" far lessor expense, DIY simply offers up more and varied choices for those who are apt to consider rolling up sleeves and gettin' it dun.
It's all good Brothers..., iffin ya use good common sense reasoning. Jerk a knee over a Screenie or overly effusive (ie: biased) review, and your apt to wind up kicking yourself with that same foot later. That applies to ANY screen...Mfg or DIY
