唔會!!
我可以肯定話你聽,唯一控制彩虹抑制最好嘅牌子只有BenQ!
我啱啱睇完Optoma 4k laser 港版,值得一讚嘅係畫面真係好靚,150寸2.35比1,超巨型畫面,但係色彩超實淨,畫面超光,對比度超高,根本冇乜挑剔,
除咗喺任何畫面都見到彩虹,黑位唔在講,連光都見到彩虹呢樣真係..... 我試咗好多段Lucy,有一幕摩根freeman 塊面啲皮膚對比靚到爆,
但係最大鑊嘅係,亦都有一幕, 佢喺白色背景天空前面行過,一個一套戲入面角色係凡人嘅人,無啦啦變成上帝,加因佢身邊有一個彩虹圈圍住個人發出光芒,一個普通人能夠喺一套係一套片變成上帝,真係可喜可賀 matt88p 發表於 2018-1-8 13:59

呢個同技術有關同品牌無關，
現時單laser的DLP投影機都是先經過磷粉色輪後再經過RGBY色輪，
用RGBY色輪是因為可以加強光度，但有說因為散熱問題，要做到部機好細部就只可以行兩倍速的色輪，
兩倍速加上RGBY再加上大反差嘅對比，會令人好易見到彩虹。
Benq嘅LK870商用機都係用RGBY色輪但用上水冷，所以部機會比Optoma嘅4K laser機大部(好似Benq嘅W11000咁上下大)
但呢部Benq一樣會睇到彩虹。

呢個我知道, but Thx for share!
所以點解佢從w11000開始個外殼從來冇變過,都係用返同一個,Lk870 本來都係我考慮之一,但係可惜冇HDR 港紙9999版本？{:1_328:} Chhanthony,matt88p 兩位大師兄對新款JVC x9900b有什麼評價?這兩個月不斷有投影機新出，睇到頭都痛{:1_332:}{:1_332:} 我都睇過U68 optima，彩虹的確明顯，同埋光到一個極係睇耐少少就開始眼攰眼乾 leekoonhung 發表於 2018-1-8 20:35

唔迷戀真4k的話而家中環境夠黑的話入JVC唔會錯。
