Picture of swmon GUI window, showing two comboboxes on the left to choose a monitor and monitor input type to switch to. The mouse hovers over the "HDMI 2" selection to the input combobox. A "Switch!" button is on the right, which actually performs the monitor switch. Information on the current selected monitor is provided in a small bottom panel.
