What is the model of the monitor?
What do you mean the graphic card is not installing?
Do you mean you installed the video card and connected the monitor - both without incident or problem - and are getting a picture but it is at the wrong resolution?
If so what resolution is it at?
Did you try changing the resolution with the monitors on screen controls? With the video cards control?
What video card are you using?
Are you sure you connected the two with the correct cable?

You really need to provide a lot more information about what is happening, your system components, and what you have tried to resolve the issue.
