Go to http://www.eizo.com/downloads/ICC/index.asp and download the F35inf.exe file. This should install the proper information to Win98SE, though with DDC, Windows should have grabbed the information from the monitor already.
Thanks very much Kachi Wachi. I done it and now Eizo F35 is recognized!
But nothing happens...
I mean that image quality remains low (for example a black straight line appears composed of a sequence of points ) and if I set the screen resolution at 1024x768 (as supported by the monitor ) now the image enlights the full screen but appears "small"...
