Is 16.7 million colors good for a mp3 player screen?
The MP3 player I am looking at is the Zen. The screen is 2.5 inches and it says that it has 16.7 million colors. But I have no idea how that compares to other players. Is that good? How many colors do the iPod Classic and the Zune 80 have as a comparison?
16. 7 million is the equvelent of to 24 bit on a computer
it should be anouth for videos and music the eye has said to be able to see 20 million
