請教投影幕 Stewart Vs OS PureMat幕分別

ccscho

Don't forget to check Kikuchi from AV Lab also.  HiVi in Japan always mention Kikuchi as standard so there must be a reason for this sophisticated AV megazine to use Kikuchi.   Kikuchi was not exported to any other countries except domestic Japan use before too.

However, Kikuchi also has different grade products, don't forget to compare products of similar price with Stewart, otherwise cheap Kikuchi will sure lose to expensive Stewart and hence lost the objectivity.

知Stewart 一定靚過OS 10-20%, 但個價就貴以三倍之多，真係十五十六中

Hifi 影音要攞最高個10 -20%，

付出嘅金錢往往唔成正比，

其實你架Sony 500 都係，

去shop 睇下先决定啦，

唔覺得值咪再諗諗先。

但幕真係好少换，你見我用左六、七年，投影机都换左三次了，

你百一、二寸，咁大部電視机要普及价都應該有排。

I remember Kikuchi is about 60% of Stewart price when I searched for screen in 2012.
(about 18,000-19,000 vs 33,000)

Kikuchi 暫不考慮，有用的Ching 都話幕易摺，品質又不及OS, 係香港到而家都做唔起，但都多謝Ching 意見。

就係話幅圖專業 18-20 呎先用 110" 咁細唔明, 我而我家 12呎就用緊110" !?

你應該睇紅色條線……Full potential pf 1080P visible ……所以1080P 120 inch is 12.5 feet apart.

幅4K圖好似suggest viewer 睇百二寸離幕7.5尺咋

超近呀， 唔通真係數毛毛！

my view is not only 10-20% improvement. if U using 500es really support U go for a good quality screen.
as U mention 幕易摺 - mostly the screen most of time is rolled up, only use very little time, once a week etc.. I use the stewart few years already still very straight in good condition because my wife watch TV prog. everyday & the screen is roll down at least 6 hours a day. 好似Ｄ衫咁,長期摺起就有摺紋,如用衣架就冇摺紋

同意樓主用得咁好既投投，

唔爭在呢少少。

好多投投用家都忽視screen哩樣嘢.誇張Ｄ比喻: BD player as Source player, projector as an amp, screen as speaker. I think U won't spend 80K projector(amp) using 6K screen (speaker) in this scale.

正如我所講projector 加screen應視為一個display system，

當年Z12000投影机的街价為三萬頭 (尾水价)，

個幕當時Stewart fixed screen 市价大约萬八，

(如買OS 只需4、5千)，所以我就當玩緊一個5皮嘅display system。

依家算Sony 500 行貨大约八萬，

Stewart 或Screen Research 123寸电，差不多价四萬多，

加埋線唔駛十三萬。

比起我最近睇嘅一部Pan 記103寸 巴士麻(買時差不多一球）為平，

但質素及享受卻更高！

閉上眼, 買了過幾日就唔覺肉痛
我剛由OS轉Stewart果下, 老婆一望畫面就講畫質係明顯幼細咗sharp咗

計算2.35:1 橫、高、對角Size其實好易:

2.35:1嘅幕, 夾角係大約23.05度...

橫 = 對角長度 x Cos(23.05)

高 = 對角長度 x Sin(23.05)

對角長度 = Sqrt(橫^2 + 高^2)

唔想計數, 可以去呢度...
