I use DesktopAlertManager like presented below but alerts always shown on primary screen.

DesktopAlertManager.Instance.SetActiveScreen(DesktopAlertManager.Instance.ActiveScreen);

radDesktopAlert.FixedSize = new System.Drawing.Size(330, 70);
radDesktopAlert.Popup.LoadElementTree();
RadDesktopAlertElement alertElement = ((DesktopAlertPopup)radDesktopAlert.Popup).RootElement.Children[0] as RadDesktopAlertElement;
alertElement.ContentElement.Measure(new SizeF(radDesktopAlert.FixedSize.Width, float.PositiveInfinity));
radDesktopAlert.FixedSize = new Size(radDesktopAlert.FixedSize.Width, (int)alertElement.ContentElement.DesiredSize.Height + 50);

radDesktopAlert.Show();

Hi, Zygmunt,

The DesktopAlertManager.Instance.ActiveScreen property is initialized with the main monitor (Screen.PrimaryScreen) specified in the Display settings of the operating system. 

It is possible to show the alert considering on which monitor the main form is currently placed. The following code snippet demonstrates a sample approach how to do it. Thus, wherever you move the main form from which the alert is shown, this will be the monitor for showing the alert: 

        private void timer1_Tick(object sender, EventArgs e)
        {
            DesktopAlertManager.Instance.SetActiveScreen(Screen.FromPoint(this.Location));
            this.radDesktopAlert1.CaptionText = "New E-mail Notification";
            this.radDesktopAlert1.ContentText = "Hello Jack, I am writing to inform you " +
                                                "that the planning meeting scheduled for Wednesday has been postponed and" +
                                                "it will eventually be rescheduled, possibly for the next Tuesday";

            radDesktopAlert1.Show();
        }

Please give it a try and see how it works on your end. Would this approach be suitable for your scenario? If not, it would be greatly appreciated if you can share more details about the exact goal that you are trying to achieve. Thus, we would be able to think about an appropriate solution.

I hope this information helps.
