The High-Gain/Exotic Screen Review - Page 7

post #181 of 200
I have lived with a 110" Silverstar 6.0 since 2005 with a Runco DLP. It has been a great screen. Its bright, has great detail and I have never noticed the screen itself during movies until now. I upgraded to the JVC RS25. Now I have millions of little sparklies over the full screen in lighter scenes, that grow worse in a central hot spot. Ceiling mounted PJ at 12-13 ft from screen. I still love the overall picture, but only if I sit in the back row now. 17-18ft. I can't train myself to ignore this artifact, so I think divorce is imminent. I know this is a ? dying thread, but I thought I'de add my two cents. It works great in combination with a dimmer PJ, but the newer higher lumen PJs overwhelm the senses with this screen. I have a fully dark dedicated room. IMHO.

When your bulb dims you'll be wanting it back!

you should consider a neutral density filter while the bulb in brand new.

An interesting thought about a filter, but I'm not sure that would solve all of the artifact problems with the 1080p projector. Might be worth a try. For twenty bucks. But screen samples hopefully on the way! I can set aside the Silverstar for a few years until the bulb dims.

Tryg,

I will be buying the 2000Lumens PTAE 7000U 3D Projector(releasing in sept)
I have already bought a 2.6 gain 135" Draper Luma 2 Glass beaded screen, plan to project at 19ft from Screen, Is this a good choice, even if i run projector in EcoMode the screen should deliver is what i am guessing, The room has a bit ambient light all the time in day

thanks
Manjunath

Try clamping down the manual iris at night (& running in low power mode), this should reduce sparklies.

Anyone interested in high gain screens, the best ones are made in portugal by a company called lusoscreen

no photoshop, no scams, this is the real thing, ive seen with my own eyes in their showroom.

I haven't heard about this screen before. It seems like a direct competitor to MOCOM screens (the same technology). I think it will have a lot of sparkles and will hot-spot like hell.
post #188 of 200
I found this company "lusoscreen" when i was searching my projector screen, their factory is about 25 miles where i live.

i didnt bought the curved screen because i had no space to put them, but i was really impressed with it in showroom from what i see.
at the time the owner himself told me that its a family business, and they being producing their screens, for more than 20 years, their high gain screen to use outside has 26 gain and is meant to be used in sport events or direct sunlight.

According to their website http://www.lusoscreen.com/pt/company/aboutus.htm their screens won a CeBIT-Home awards in Hannover em 1996 and a gold medal in genebra inventions event in 1997 .
At the time it was the only screen in the world capable to work with direct sunlight , and their home theather screen has more 500+ contrast than a white screen, I think at the time of my visit it was mention their home cinema screen had 13 gain, but can remenber well.

150cm (with wood +/- 175cm) (4:3 or 16:9)
200cm (with wood +/- 225cm) (4:3 or 16:9) price 880€ that about 1.150$
234cm (with wood +/- 260cm) (only 16:9)

ps: dont no how much the other brands charge for their high gain screens, but this one looks like a bargain and they are not made in "china"
post #189 of 200
Their website is laughable. No prices, no technical specifications. Contrast >350 times than matte white screen? In what conditions? How did they measure it? Sorry, but that's not credible information. Famous leader in the industry DNP produces a very expensive screen which has 8 times more contrast than MW screen in high ambient lighting conditions. And that's been tested. Also their screens are concave. Which means there are certain conditions which must be met when installing it like position of projector and audience. No info about that on their website either.

If this screen is so great why you still don't own it?

if you had read my posts carefully, i mention that i dont have space in my living room.

Why dont you email the lusoscreen company? The owner is Mr. Candeias .

In a exchange of emails with lusoscreen, it was mention that screen was mesured by the portuguese laboratory of civil engineering.

Seems very credíble to my own eyes, i just pass this information on this topic because it seems theres no much subject on this type of screens around .

And the one that exist cost a arm And a leg.
Its seems in other tópics no one believe either that a seiki 4k screen cost only 1299$

This screen is live And very real, And is manufactured in europe.

I see that the camera stays fixed at roughly screen center, and I suspect that there's severe gain dropoff as you move off center.

Also the screen is curved, which may help things but is impractical for most people.

Please, dont based your premises in something that you read or have reviewed from other screens type , you havent actually see the lusoscreen or tested to assume or suspect any gain drop.

See the 2 lights on the pictures, this are normal lamps and the interference with the screen is minimal, that tell how much this screen can perform in daylight.

Dont no how´s the google translate works from portuguese to english, but i would try to read the interesting conversation in forumhifi about this screen.

http://forumhifi.com/forum/showthread.php?31877-Ecr%E3s-Lusoscreen-Home-Cinema

Some members from the forum (isf certification) sugest in doing some tests with professional gear in near future, im also looking forward to see the results, its not everyday that i have a possibility to see a screen like this in front of my eyes.

(My grandmother said was bad q ) Finally, at first glance, it seems to me that the brightness is not distributed evenly across the screen, ie, there mto brighter than the center to the corners (even with the curvature of the screen ).
That's all I needed to know. And I agree with that guy:

In a room with projection home, had a light, would see all the furniture, the lamps, the woman reading magazines .... N would distractions. Besides that fact would lose resolution in black, however good the screen to reject the light

I'm basing it on the video you linked, and on physics - it's impossible to get high gain without dropoff; the only way to concentrate a given amount of light in one place is to take it from somewhere else.

Well my friend "noah katz" and illustrative reviewers, its time to pull the "cliche book" about high gain screens vs gained drop off if you move off center.

A few weeks back i mention this topic to lusoscreen company owners , and they where happy to make/show new personnel videos with the camera position off-center.

first video is direct sunlight from several angles (outdoor high gain screen)





the second video is their home cinema screen with the camera filming on the side of the screen .





Has you can see, this screens dont need bulls****t marketing videos like are showed on the web

post #196 of 200
That video is not a good test. They need to pause a bright scene, and then use a light meter. Using a camcorder doesn't seem like " proof " of anything either - won't the camcorder adjust gain to compensate for less brightness at an angle? Mine sure do.

Better to see one in person. Then decided.
post #197 of 200
canton,

Craig is exactly right.

Gain vs. angle is technical data, which means numbers, and your videos do not provide any.

First this are not my videos, this are luscoscreen video, and im not afilliate with lusoscreen, im a consumer that happend to live 20km from lusoscreen company, and had the opportunity to see this screens when i bought my cinema screen from them.

the videos:

If anyone doubt the video camera has a fix settings, please take a look at the videos "again" and look at the area outside of the screens, doesn't maintain the same brightness all the time ?? that means the camera has fix settings .

"to understand what im talking about , pls ask to someone a technical explanation about camcorders"

What other type of high gain screen can achieve that amount of quality in direct sunlight ??? on the front , on the side , moving camera or even fix camera.

In the video the open space/field where the screen is, everyone can see that the brightness is the same, so no video camera cheating of any kind .

Like you mention Craig, better to see one in person, if you visit portugal one day, your time will not be wasted...

Dont even try to get off topic, if you dont have anything interesting to add to the conversation stay out of it.....no trolling pls

Lusoscreen ?? who the hell is lusocreen? they have presence in forums ? hell no.... well then they dont exist... rolleyes.gifrolleyes.gif and does video are pure imagination on your computer screen /S
