I must say I love all this technical jargon. Jargon like "Resized
Dynamically". What other ways of resizing are there? Can images be
"Statically Resized" too?
"Dynamically resize" may mean the image is distorted to fit the screen
proportions. If the image has to be enlarged to fit, there will be some
fuzziness, which may be an advantage for a background image. It works
well only if the image proportions are the same as your monitor's. Eg, I
have an "HD" monitor, 1920x1080 pixels, or 16:9. Any 16:9 image will fit
exactly.
Of you don't want to see distortion, resize and crop. "Static resize"
can be done with image editing software. (Several image viewers have
such basic operations built in. See below). Find your monitor's
dimensions in pixels, resize to fit the horizontal measure, then crop
off top and/or bottom to fit the vertical measure.
Free image viewers with basic editing software (and other goodies):
Irfanview, XnView. I can recommend them both, they have different strengths.
