Since I've never had a 2.39:1 screen I've become accustomed to the top and bottom bars on most movies so sticking with 16:9/1.77:1 wouldn't be a change for me. If I got 2.39 it also seems like a pain in the butt to be adjusting the zoom between different formats and re-positioning the lens, thus would limit my projects options in the <$3,000 category to pretty much epson since they have the powered memory lens's. Is that about right? Am I thinking about this all wrong?
Well...kinda sorta, then again...not at all.
The object of going Constant Image height is to allow for the ability to have a epic-ally wide 2.39:1 presentation by making the screen as wide as the peripheral vision will allow, therein also retaining as much Image Height as possible for 16:9 content. So...many simply take the height they want for 16:9 and then add the width needed to expand the screen parameter to 2.39:1. No height lost on Football & Basketball games, but when the Blockbuster is on.....wow.
Also, there are these two important points to consider.
- The Horizontal Format Bars on 2.39:1 show a larger percentage of unused Screen real estate than do Vertical Bars seen with 16:9 within a 2.39:1 field.
- It is extremely easy to mask Vertical Bars using Panels or Curtains. It is far, far more difficult to mask Top / Bottom Horizontal Bars...**
As an addendum to the last Bullet, if the Projector has Motorized Zoom / Lens Shift and Lens Memory, a "large as possible 16:9 image can be used, and when 2.39:1 is shown, the image shifts downward so that the area left unused at the top can be masked by simple Pull Curtains.
I done both repeatedly, both dependent upon the preference of the Customer, as well as the choice of Projector and available Throw.
HOWEVER.......there is another choice. If possible, painting the entire wall with a high performance Contrast Enhancing Grey Screen Paint can allow for the best of both worlds.
- When 16:9 is desired, it is zoomed to be as big (tall) as the occasion demands.
- When 2.39:1 content is shown, it too can be made to be as wide as possible
I call that a *NFSSW". Ergo: Non-Format Specific Screen Wall.And here is the best'est part....using the right Paint, you "do not notice any Image Format Bars". Yep that's right....and that being the case, no masking is required.
That application works so well to the advantage of the viewer that over the last 3 years, every single Painted Screen application I have installed (...and there have been many...) for someone has been a Screen Wall (...in both Theaters and Family Rooms...) the appeal of having infinite (almost) flexibility in choosing image size is the veritable Icing on the Big Picture Cake. Add to that the sheer mystique having a Wall look as good as or better than a multi-$1000 Mfg Screen and there is no better entertainment value nor anything that will impress others more.
Also MississippiMan props to your avatar. We named our son Korbin, that's how much my wife and I love that movie lol.
Yeah....I've seen that Movie at least 500+ times. No foolin'. It's a staple when I demo my systems at Home Shows...(somebody come get me...I'm in the Front row!!! ) and an excellent one to use when calibrating a system with actual content.
BTW...our Cat is named "LeeLoo".
