It's just how they work. Laptops, desktops, LCDs. Doesn't matter. If your laptop has adjustable resolution, and you find that the image quality looks equally great at all resolutions, then perhaps you just haven't tried it at its native resolution. Whenever you display, on a latptop or other flat panel, a pixel rectangle whose dimensions are not equal to that of the display, it must do one of three things: * Use a subset of the screen (if the display image is smaller than the screen) * Truncate the image (if the display image is larger than the screen) * Resample. This means that the pixels that you see being displayed are dynamically generated from resampling the actual pixels in your image. If this is happening and you are very pleased with the results, then you are lucky, because you please easily. If you don't believe me, and you are a photoshop person, you can test this for yourself by building, in photoshop, an image that has alternating columns and/or rows of two-pixel stripes, and displaying it on your screen in "show actual pixels" mode or in a browser, and looking at the results under a magnifying glass. I consider this thread quite on-topic for the LUG because it is about how to optimize image quality with the tools that we use, and how to understand the means by which we can make the best pictures that we can make for the display media available to us. - -- To unsubscribe, see http://mejac.palo-alto.ca.us/leica-users/unsub.html
