If you have ever tried to get an LCD tuned just right when using a KVM switch you’ll know that the key is in the pixel clock and the phase settings.
Download and use the attached gif as a test image with which to tune your screen.
Make sure that it is being viewed at 100% (not scaled in your browser) and set your pixel clock so that the pattern is uniform across the screen. Set the phase such that there is minimal distortion or "static" on your screen and you should end up with the best viewing settings on your monitor.
