Dell 2709w
Color Support:
1.07 billion colors; 110% color gamut

spec.

而其他機種都是 16.7 million.

目前我只知道天價HP DreamColor LP2480zx 有使用真正 30bit panel (1.07 billion colors)且支援10bit 顯示卡.

Q . What is the benefit of using a 30-bit graphics card with the HP DreamColor LP2480zx
display?
A . With a 30-bit/pixel-aware OS, graphics card, and application, the user is able to display
images that choose from the full palette of 1.07 billion colors. This is primarily important
when the source data is inherently greater than 8 bits per color. Examples include medical
imaging or satellite imaging where the source data can be from 10 to 16-bits per color.
