I still think it is highly sensitive to what monitor and vga cable that are used. Like for instance. My Sony monitor....
If I use it on my IndivisionECS V2, then I have never seen such ghosting on vertical scrolling in my entire life. It is in pinball dreams and fantasies. It is like really bad. And it is not only when using the IndivisionECS V2. When using that monitor on a 486dx33 ISA-Only motherboard with an Orchid ET4000 ISA card and playing Dynablaster in MS Dos 6.22, then all vertical lines will start to make a wave motion 0.5 centimeters to each side. And other games have troubles.
Yet I need that monitor, as it gives perfect picture on my other Amiga500. That is a revision 8a.1 board, full ECS chipset and with an ScanPlusECS scandoubler that only outputs 50hz refresh rate.
Yet on anything non-50hz and non-Windows98, it really sucks.
