I don’t want to make the same mistake. I HATE my screen.

Hi, I need help making sure I don’t buy the same type of material for my projector screen.
I own an Elite Vmax electric version 1, I’ve had this screen for over 13 years now.
It has like a reflective coating on it, it’s white with like a pearls or some shiny coating that seems to float on top,and it looks worst when something white hit the screen; could be a bright light on the movie, the sun, a white anything, will make this reflection even worse.
What is this screen finish called??
Reflective white?
Do I need to buy grey?
Are all white screens reflective?
Needs to be 100 to 135 electric and no need of conetention.
Thanks!

What you're describing is typical of a high gain screen. They work by reflecting light back at the viewer and can be noticeably sparkly. A 1.0 gain screen will eliminate this. Typically high gain screens are used if the room is not properly light controlled or the projector doesn't have enough lumens for the screen size. A brighter projector in proper light control with a 1.0 gain screen is desired.

Get some screen samples to compare to your current screen. I don't see those issues with Stewart's less expensive Cima Neve 1.1 gain white screens. Or, there are unity gain screens.

A unity ( 1 ) gain screen also sends light scattering in all directions, so they really only work well in rooms with very dark ( or black ) non reflective surfaces ( which you more or less said there ). Screens with gain send less light onto the side walls, ceiling etc. - and with HDR - there once again isn't enough light from most projectors, so we need all we can get. I find my 1.3 gain StudioTek 130 perfect on a 118" wide 2.35:1 screen with my RS4500 - but only with a Panamorph Paladin DCR lens. Zooming, it still struggled a little light output wise, unless run in high laser ( it seemed OK until I got the lens ). Of course Blu-ray / 1080p is no problem at all, and 16:9 is.

Unity gain screens were great until HDR came and screwed things up !

High gain screens are chock-full of problems so I don't think high gain screens are the answer, even for HDR, just a temporary band-aid (and an expensive one). The answer would be of course for pj manufacturers to make 5000 lumen (calibrated) projectors with the same black levels as JVC has so we can use our old unity gain screens with them and not suffer aberrations caused by the screen. (though I'm not sure a pj with a black floor of .0002 going to a full white at 5000 lumens would be comfortable, visually)

I don't consider 1.1 - 1.3 gain screens to be " high gain " myself. That's a term I reserve for screens like the High Power and Vutek Silver Star screens.

Fair enough, though 1.1-1.3 gain screens don’t get you in the ballpark of what’s needed to do justice to HDR for most HT projectors, which was what I was responding to...I was thinking about this crazy 5-7.0 gain screens like Silverstars. Either way, it would be nice if pj manufacturers would make up most of the brightness difference and not rely on screen gain. I have high hopes for laser pj, I sure wish Epson would modify the LS100 to modulate light output for dark scenes (and change to 4K panels) or add manual iris (or both!) then we’d be getting somewhere! I think a 5K Lumen (calibrated) 4K laser modulated pj that could even do 10,000:1 on/off would be a thing to behold! The fade to blacks (light source off) followed by a bright scene would bring tears to everyone’s eyes! (And maybe make your nose run a little...). I’m hopeful the industry is getting close...I’ve got a piggy bank I’m waiting to break open.

I'm totally with you on that. I'm currently getting 47 foot lamberts for scope for HDR, but my StudioTek 130 is 128" diagonal. So if you keep your screen size reasonable, you can get a bright image. I don't have the throw distance to use a larger screen anyway. But we sit just under 10' - about one screen width away, and it looks fantastic.

You can buy some an Elite sample pack for Cinegrey, Cinegrey 2d and Cinegrey 5d for just 8 dollars.. to test.

The sprakle-effect is a terrible problem. I suggest a 1.0 matte white or specific ALR screens that are not affected by the sparkle (very very few).

I don't see any sparkle effect on my Stewart Cima Neve screen, or Studiotek 130 for that matter. Screen shots on my Cima Neve ( 4K Blu-ray, about 35 foot lamberts ) -
