购置投影机的第一件事当是确定投影机的分辨率,但你马上就会被分辨率的两种不同规格搞糊涂——原有分辨率和最大分辨率。厂商往往把最大分辨率放在介绍的很显眼处,而原有分辨率(也有称固有分辨率、物理分辨率)的指标则被放在不显眼的地方,甚至广告上都见不到。因为最大分辨率的数值会比原有分辨率大很多,好看些,而投影机的价格档次基本上是按原有分辨率归类的。这样做,会给你一个性价比高的感觉,但如果你不了解两种分辨率的内涵,就有可能被误导。
The first thing you should do when purchasing a projector is to determine the resolution of the projector, but you’ll soon be confused by two different specifications of resolution - the original resolution and the maximum resolution. Manufacturers tend to put the maximum resolution is very conspicuous at the introduction, and the original resolution (also known as intrinsic resolution, physical resolution) of the indicators were placed inconspicuous place, or even advertisements are not seen. Because the maximum resolution of the value will be much larger than the original resolution, look good, and the projector’s price level is basically classified according to the original resolution. This will give you a cost-effective feeling, but if you do not understand the meaning of the two resolutions, you may be misled.
