I want to make it so that there is the text "Display 1" at the top right corner of the secondary display on my computer regardless of the number of applications I have open. No matter how I move the windows open or drag them around, the text "Display 1" will always be there. Though I can customize the text to show some other text.
Is there any application that allows me to do this? I want to use it in a presentation I want to give involving multiple applications running.
