If they have different light sources, then it might offer a wider color gamut....
Double lamps give it greater brightness.
However, I have yet to grasp what this concept is all about -- as in how can a monitor go beyond the full black to full white greyscale range (realizing that it is actually a combination of red, green, and blue)? And how does the lamp factor into this (special CCFL tubes vs LED vs standard tubes)?
Explanation:
For the sake of simplicity in I’ll stick to the HSB (hue, saturation, brightness) and LAB color spaces as it applies to the BrightView issue (with a quick digression into RGB for comparison sake).
HSB is what most of think of, although we don’t know it.
Hue describes what we normally think of as color when differentiating red, yellow, green, blue, violet.
Saturation is the intensity of the color: i.e. just plain red or
hot red.
Brightness is the degree of brightness intensity: i.e. faded yellow or deep yellow.
LAB (pronounced ‘L’ ‘A’ ‘B’ --not ‘lab’) separates all contrast into one channel and color into two channels. This is by far the most powerful color space. The gamut is so wide that it contains imaginary colors. (If you want to know more I recommend reading the first 2 chapters of Dan Margulis’
Photoshop LAB Color book.) LAB is the color space that is most similar to how the human eye works.
L contains all the contrast from white to black with no color
A contains no contrast and only describes the color range from magenta (roughly) to teal-green (roughly)
B contains no contrast and only describes the color range from yellow to blue.
RGB is Red, Green, Blue.
Color and contrast are mixed in this color space. Each channel, when viewed on its own, is a black and white image but when mixed with another channel color is revealed. There are various flavours of RGB with varying gamut widths (the range of color variation). In order of increasing gamut; sRGB is the default for web use. AdobeRGB is common among photographers, ProPhotoRGB is increasing in popularity as hardware gets upgraded to handle the increased demands of this color space.
Current monitors can’t display truly wide gamut--laptop monitors being more prone to this. This is why I’ve been so interested in the Ultra BrightView since maybe there was some breakthrough. However, my guess after a lot of searching is that it’s only the brightness gamut, and
perhaps a small amount of saturation that is being increased, while the hue gamut remains the same. This means that for photographers the Ultra BrightView isn’t actually useful. Instead the increased resolution of the WSXGA+ will be more helpful since more image can be seen while in Photoshop.
