I think I know what you are talking about. You can see a "line" where where there is a slight change in color/brightness, right?
This is more or less the difference between a CRT (analog) and an LCD (digital). Though, there are much better LCDs than a Xenarc, where the difference is not as noticeable.
I believe the Xenarc is a 6-bit LCD. What that means is that the data for each sub-pixel has 6 bits. In binary thats a number from 000000 to 111111, in decimal that 0 to 63. the sub-pixel can then "open" to 64 different positions from black to full brightness of whatever color it is. A pixel is made up of 3 sub-pixels, one red, one green, and one blue. This gives you a possible 262,144 diferent colors (64red*64blue*64green=262,144).
An 8-bit panel could display 256 different shades with each sub-pixel, and ~16.8 million different colors. This is enough so that the human eye won't notice the slight changes in color that you are seeing.
Most panels these days are 6-bit, but can do something called dithering. This is basically switching the color quickly back and forth between two shades, which kind of gives you extra colors. At least it appears to the eye as if it is a shade in between. I think that whenever you see a monitor that advertises 16.2 million colors (vs. 16.8 for true 8-bit color), it is dithering a 6-bit panel.
