投影幕一問

henrylaw

家中投投與幕大約有6.8米距離，請問我應該跟幕定畫面黎計呢? 16:9最少應用150寸定200寸幕

You use the diagonal screen size that you want for calculation.

usually: 6.8 * 3.3 * 12 / 1.5 =  179.52 inch screen wide = arround 206"
入到LIFT同轉到灣當你贏，一係用FIX SCREEN

如果你計喺6.8M可以睇幾大，可以用頭先條式
如果你計部投影機係6.8M距離投到幾大咁就要睇機個spec

even 150" is huge by any standard, going to 200" you will need a really bright projector a bright projector with great contrast and color accuracy will be lots of $$, not that I am doubting your buying power ching  

Look at this guy, his screen is actually 158”, I’d be more than happy, in fact go crazily happy with this kind of screen size !!
