ideal resolution used for surfing also depends of the monitor used cause some monitors are blurry at certain resolutions
Im using now a NEC multysinc 22 aperture grille crt monitor and the manual says 1600x1200/85hz ideal however I use 1152x864/85hz or 1280x960/85hz
I have discovery that the most high refresh rates= +blurry image and the most low refresh rates= +sharpen images however on low refresh rates you will get + flicker...so you must found the best intermediate point
