[comp.sys.mac.hardware] rasterops 24s and seiko 1445

I would like to check with you guys out there who own seiko 1445 monitor.
For some reasons, with my IIsi when the desktop pattern is set to checker board pattern with the following settings:
				dark tiles		light tiles
		hue			0			0
		saturation		0			0
		brightness	    30583		    34952
		red		    30583		    34952
                green		    30583		    34952
		blue		    30583		    34952
The monitor is showing same sort of shadow of the outlines of the window and the title bar.  The shadow is not terribly noticable but it is there.  I also notice that this shadow apppears for the outline of the windows only, not the icons ..etc.
I called up Seiko and they told me to try to connect my monitor to test the monitor to the internal video since they suspected the video board (rasterops 24s).  However, this problem is still there when I tried it.
Do any of you know what is going on?  The problem only occurs with the above settings.
