Well duh... this is expected behavior. I can say that based on my
estimation of editing in excess of 200,000 images in Photoshop over
The "rule" is the lower the resolution of any RASTER BASED image the
more pixilated it will become as you zoom in more. This does not
impact the image quality itself...only how it's quality (or lack there
of) is perceived by you on screen.
For background purposes there are two families of images common to
computers. The first and by far the most common are raster based
commonly called bitmapped files of which there are many file types
such as JPEG and TIF, being such images are created from a collection
of rectangular pixels. The more you zoom in on ANY such image, the
more obvious the pixels that make up the image become, similar to if
you look at any newspaper image close enough you can see the pattern
of dots that makes up the image.
A vector based image is comprised of geometrical primitives such as
points, lines, curves. Example some Flash image. These can be zoomed
in or enlarged without loss in quality and you won't see pixelation.
I'm trying to be gentle, but the "problem" seems more your lack of
understanding of the basics. The ONLY logical reason why you're seeing
something "different" is in fact YOU are doing something different on
your new computer verses your new one. It may not be obvious to you,
but you must be the case if we are to accept everything else you said
at face value.
Either your monitor's size/screen/resolution is different, the window
you view images in (it's size on screen) is different, your graphic
card's resolution is different or it's color depth... something has
changed or the image you're looking at is in fact not the same either
in it's physical size or resolution. There's no getting around it.
