In general, PocketPC supports high-DPI and Low-DPI (192 and 96 respectively) display modes. As you know, image with fixed resolution will be displayed in a smaller size on Higher DPI screen. For example, images on 192 DPI screen will have as 1/2 size as on 96 DPI's. To maintain a consistent image size in both High and Low DPI mode, PocketIE introduces Pixel Doubling, which simply doubles the pixels used in High-DPI display. Just like an auto zoom out on every image pIE is browsing.
