Projector SCREENS acer 5360 what type screen new thread specifically on projector screen advice
  1 / 3    
Just bought my acer 5360 dlp, after reading the excellent advice on this forum - ie main thread below

[url="http://forums.nvidia.com/index.php?showtopic=152758&st=280"]http://forums.nvidia.com/index.php?showtop...2758&st=280[/url]

But what screen is best suited for 3d vision gaming, the ideal screen seems to differ for 3D over normal use where matte seems to be the norm.

one comment from 'tritosine' is copied below

[b]I found matte white screen bad for 3D vision ,way too dark you should get a screen with gain of at least 1.8. Thats not matte white.[/b]

any more views and comments regarding screen, also any suggestions for UK to buy a screen from

ive found plenty of online outless selling matte and grey screen but not gloss ?

thanks in advance...

Below is a detailed overview of all screen considerations for the normal user

interesting read - but how relative it is regarding 3D Vision - I have no idea ?

You can use any type of screen you want, as long as you understand the consequences of high gain screens.
Nvidia 3D vision uses shutter glasses, so there is no need for a non-depolarizing "silver" screen. You can use any material you want.

Using high gain screens has pros and cons. High gains differs from matte white in the sense that they redirect more light in front of the screen and less light to the side.
With a matte white screen you can sit or stand anywhere in the room, the picture will keep the same brightness.
With a high gain screen the picture will be brighter if you are right in front of the screen and darker if you are on the side.

The Gain number of 1.8 means that if you are right in front of the screen (in the optimal position) the picture will be 1.8x brighter than with a white matte screen (which has a gain of 1.0)

I found this snippet below, which is [b]NOT [/b]related to 3D Vision, going by the above, it wud seem this is less so for vision users ?

[i]Polarised light systems use 'silver' screens, which are intrinsically high gain (around 2.4). The maximum screen size which can achieve 5fl with a single projector, is about 14m (20m+ with Real D XL).

Other 3D technologies use 'white' screens but also require high gain. Recommended gain levels are 1.4 from 8-10m; 1.8 from 10-12m; 2.2 above 12m.[/i]

[b]Thanks BlackSharkfr [/b]- getting direct feedback is so much more helpfull than reading related web articles which aren't Vision specific

These Harkness screen information charts relate to cinema screen sized with theatre type projectors (with big bright and hot Xenon lamps).
In these charts the closest system to 3D vision described is the XpanD system, which uses shutter glasses.

However in order to know the most interesting screen gain you want, you'll have to recalculate the screen brightness yourself on your system with your own screen size, the screen gain you choose and the actual brightness of your projector : do not trust the Ansi Lumen rating of the projector, it's false on almost every projector, try and find a review of the projector on which the reviewer measures the actual amount of Ansi Lumen produced.

I have accurate measurements of the H5360, done by Balagee at www.projektor.hu HU = Hungary, and Im hungarian. If you want , I'll translate the whole. The verdict is , its a very very fine "jack of all trades" pj, you can't really blame it for the price. The color balance is nearly unheard of in this category , no abuse of Brilliantcolorâ„¢ either.
Interestingly , once you go 120hz, brightness drops to 750. Yeah, right, not over 2000 , but 750. Contrast to 1000 ...

Brightest mode, ECO off: 2150 lumen
Contrast: 2600:1


User mode, ECO on, ( his preferred mode for movies , with a few tweaks , no wonder, 2150 lumen is just too much fo that)
Brightness: 1300 lumen
On/off contrast: 2100:1

Movie mode ECO on, ( good to start with , but user mode can be tweaked to better)
Brightness:: 1030 lumen
On/off contrast: 1700:1


120 Hz/3D mode ( ...sadly)
Brightness, ECO off: 750 lumen
On/off contrast: 1080:1

... Well yeah. Its the best once running brightest. It can be improved upon further with static iris mod, 2100 lumens would drop, but on off contrast would benefit.
EDIT: change of plans

Ouch !! 750 lumen and then drop 4/5 out of it trough the glasses. Indeed that's dark.

Harkness screens may be expensive but from what I've read they're simply the best for polarized setups.

Thats a glass beaded retroreflective screen. This is very important. You should read about what it means, ceiling mount is no go then.

It should work with single pj , but provides no upgrade path towards polarized setup. Similar high gain screens can be bought that give the gain like that , and going to work with polarized light later on. Those arent retroreflective either but angular reflective.

One of the best projection screens you can get for not much money is a Wilson Art Laminate...the Designer White one.
I have been doing projection for a LONG time and have tried many. I normally go with Blackout cloth due to my screen size but since matter is not too good the WilsonArt which I think is 1.3, should workout nicely.

Great thread so far. What about a RP setup? I'm hoping in a completely light controlled room, with RP, that some of the brightness/contrast issues go away.
