[RESOLVED] How can I install a second monitor in NT 4.0 SP4?

Hi folks,

I'd like to use a second monitor in Windows NT 4.0 with Service Pack 4.
I got the Diamond Viper V550 AGP and a Cardexpert S3 Virge DX PCI.
In Windows 98 its working with 2 monitors and I heard that it should be running with NT4 too.
The problem is, NT doesn't recognise the second display adapter itself and I can't find any possibility to integrate it by hand.
Does anybody have a solution for my problem?
If yes, please email me at [email protected]

Bye,
St. Tommasini
