Are you using any sort of program that claims to speed up a dialup connection? Most of those work by reducing the quality of images to cut down on the amount of data needed to be downloaded, along with other stupid tricks that don't do more than give the illusion of increased speed.
Anyway, if you're using such a program, disable it and the problem should go away.
I am getting blurry pictures and images in the 17" Dell Monitor.
In order to have a clean page, I click the right button of the mouse and and go to "Refresh Page with Full Quality".
Please let me know how could I correct this problem.
