It's not just you. I've written great comparisons of how much the pentile display kills image quality and ways to blatantly see the problems. It was the very first thing I noticed when I turned the phone on and went "oh god". Even the battery meter in the notification bar shows alternating color-dark pixels in its display. I'll just copy everything over, here you go. Pictures are left in Url format to keep the post shorter.
Green and orange seems to be the most susceptible to the banding problem. Viewing this image on a computer or DX and then on the DX2 makes the problem even more blatantly obvious:

Viewing this page makes the text problem VERY obvious:

It's a hardware limitation. The technology is called "pentile" and can be read about here:
PenTile matrix family - Wikipedia, the free encyclopedia
After reading this, it's obvious why the green is having the largest issue with displaying properly. The Atrix apparently uses the same display and people are complaining about that one, too. Google has plenty of hits on it.
Perfect examples of what's going on. The image quality difference is blatantly obvious. The DX1 display is the same as the top examples in each photo, the DX2 display is the same as the bottom ones.

Looking at the photograph example, look at the horrid loss of detail in the pink and dark green areas. Imagine the stripe example as a lower case "L" and look how jagged it appears in color.
