VIVIDSTORM始终希望为不同投影机的需求提供最佳选择;
如果您的投影机流明较低,请使用长焦或标准焦的投影机;
但想要在弱光条件下观看屏幕;
因为我们有3D黑曜石 ALR和普通黑曜石 ALR屏材质可以选择,以前购买时会很困惑;
我们建议您可以通过视频选择适合您的屏幕材质:
总结:
请记住,市场上存在错误标注的流明指标,因此请以ANSI流明作为标准参考值;
答:如果您的投影机ANSI流明低于1800,我们建议您选择1.2增益3D 黑曜石ALR屏幕材质
B:如果您的投影机ANSI流明高于1800,我们建议您选择0.8增益的普通黑曜石 ALR屏材质

Shouldn’t you also consider screen size in addition to projector brightness? For example, 1000-1500 lumens on a 100" diagonal screen is quite bright (100-150 nits), while on a 140" screen it’s much reduced (50-80 nits).
My specific situation: should I pick 3D Obsidian ALR or Normal Obsidian ALR for a 100" diagonal image, with a 1000 lumen (calibrated, not spec’d) projector, in a room that is completely dark however it has light colored walls and a white ceiling that reflects a lot of light back to the screen?
