Don’t assume that we can see your set up, we can’t.

To be able to help we need a clear and detailed picture of your set up, including, what operating system you are using, what hardware, what is connected to what and how, what settings you have… Detail please, lots of detail.

For “self help”, start from “connecting up” in the manual:
