In Dewesoft X3 you can use many monitors for displaying separate Measure screen. This is a simple how-to step-by-step.

1. Make sure that all displays are connected to the same PC and visible in Windows settings. To check this go to Settings -> System -> Display. The screenshot below shows a primary monitor and one secondary monitor. 

2. Setup the measure displays under the Displays tab with the use of the + button. 


3. Under the Multi-monitor settings -> Monitor selection, you get the dropdown menu with possible Secondary monitors to which you can assign Displays. At first, choose the Display and then click the Attach button. Repeat the last step to the other monitors. 

Note that you can't attach the Display to the Primary monitor.
