I have a model CM9089 BE41 Magnovox Super VGA monitor that will not work with the onboard adapter in my new computer. Nor will it work on my Toshiba Laptop. Both these computers are running Win 98. However, it does work with my old 486 which is running Win 95 and runs on a friends Win 3.1 machine. Is my problem WIN 98 or is it that the new onboard adapters will not work with the older monitors?
