Oh BTW the 3D is awesome on these, it's like - in your face lol
it uses active 3D glasses that needs to be powered on.

tried to look for a 300" wall last night & this is what I found around our factory, talk about portability

here's a nonsense test done on a $5 tarp with different shades
Luckily the other side was a non-reflective surface which can be used in lieu of a white flat surface.

I really have no idea about this test but it seems that the yellow/ bright shade will be more view-able with the lights on although the dark shade area have more contrast, size about 75 inch

ordered from a tarp shop with different shades made in MS Paint


with Light ON


Lights OFF


Luckily the back is non reflective but they say reflective is much better


Lights ON


Light OFF, pictures are much better than the one taken from a cam phone

^ A good screen can make a huge difference in picture quality. I use a low gain screen at home, makes black levels and shadow detail much better even on my rather dated projector. When the lamp dies i'll probably get something like your XGIMI.


Test image shot in darkened room using Galaxy S4. Camera is terrible at low light shots, the gamma bars are actually discernible all the way through.

For your PJ i think low gain is also the way to go. Your max brightness is high enough that it won't be a problem getting good white levels even on a gray screen, and it'll make contrast and black levels better.

for the mean time I usually just use the wall that's painted like milky white & I place a pure white paper in between & you can really see the difference. What are those grain thing like 0.8 or 1.0?

anyways I had a chance to try this little thing outdoor last night since I came back to the factory late & not a lot people around
just wondered how it would look like on a huge wall though not totally dark coz of the street lamps, The Cc would be a little brighter if plugged in.
i guess the Cc was more than 10 meters away from the wall, not sure how big the screen is though.

^ Not 'grain', but gain, which tells you about the screen's brightness

1.0 will be a white wall
below 1 will be grey
above 1.0 will be a different material that's more reflective

Low gain screens can give you better black levels.

There are also ambient light rejecting screens where the material is designed to absorb or diffuse light coming in at an angle (ambient), while reflecting direct light (coming from projector). These can make for a good picture even if the room isn't dimmed.

Like so: (undarkened room, regular projector screen top half, ambient-light rejecting screen bottom).

so the ALR screens really work ha, I just got me a tarp & yesterday I got a white satin sheet & luckily the other side is not reflective, will give it a shot after I iron it out

meanwhile my wall will suffice 

[wheelee]

just got those reflective cloth, first was the thick light gray one which is used for EWD on clothing which was delivered folded & the other was a little dark gray thinner material which was delivered rolled. The first was much heavier & thicker than the 2nd cloth. Yes the viewing angle is really small as can seen from the sample shots, some shots where taken at an angle around 30deg (estimate) while other shots where taken Head on. It seems the thick reflective cloth is more brighter than the other but not very much. got both in taobao here in china. oh how I wish I could put a Frame on these!
 
 can you imagine shining a 1200 Lumens on these, my eyes

Nice, is it easy to install?

Nice, is it easy to install?

it's as easy as turning it on then pointing it on a white wall - kung mga madalian na setup lang
pero kung dedicated AV-Room yan ibang usapan na yan

[wheelee]

another ALR screen test - viewing angle is  very narrow but view-able during the day or in ambient lighting but i guess this screen is good for those cheap projectors with low brightness.

windows open around noon
 

night time, lights on


day time, center view


daytime, off center a bit


off center, wall is even better at this angle


different side, seems light eh reflection of the cloth is different from this side


off center/ all lights off

my son gave me an Xgimi Z6 for my bday & the wow factor on this is awesome! HDR10, Motion compensation (motion blur?) 2D to 3D - it really works & the Z6 is really small compared to other 1080P PJ's

Z6 & CC


guess the Z6


45 degrees to the ceiling with -38 keystone adjustment




it does have some teething problem but hopefully firmware can fix it.
Directly below the screen in the ceiling with -38 keystone adjustment!


About 95 inch screen size, Projector distance around 8 Feet
Z6, 4K Movie output to 1080p






with 3 12Watts PL lamps on

[wheelee]

check out these Z6 pics, according to the poster these are just projected on a painted wall! these chinese made projectors are killing it!






from Xgimi's bbs site in chinese > http://bbs.xgimi.cn/thread-130027-1-1.html
no need to go to theaters anymore lol, just wait for those 4K movies to be released

I just got a Vmai M200 pico projector for my son's birthday since he watches a lot of anime's & TV series. These pico pj's are sprouting out here in the middle kingdom by the day! main audience are the young people or working group who have to travel from place to place so have to travel light with a whole entertainment center in the palm of thier hands - litterally.

the M200 is a 720p pj(according to xbmc info) & is about 200-250 ansi lumens(from my observation, compared to my xgimi CC & Z6) which is ok for a darkened room. It has a built in speaker which is suprisingly loud BUT NO headphone jack, why? Did I ask why no HP jack? Well there is wifi & Bluetooth so connectivity is covered there & it uses Andy version 6. Language is a mix of english & chinese. It uses auto keystone but focus is manual via top button.

what i dont get is why they had to use a dongle for the remote which takes up one USB port. I tried the Xgimi remote via BT & it works fine. it's just amazing how they fitted everything inside this tiny thing AND is battery operated too! About 2 hours according to spec & that black little strip below the pj acts as an adjustable mini stand BTW.
 
anyways below are some pics taken by the LG G7 which made the pics a bit brighter than the actual lumens.
