Support multi-monitor video wall
The Video Wall feature extends video viewing across several physical monitors for control-room or multi-display setups. Every enabled monitor shows its own borderless, full-screen grid of video windows, as the following:
Click the Video Wall toolbar button and configure each screen in the Video Wall Setting dialog: enable the screen, set the grid rows/columns (up to 5x5, 25 windows per screen), and set bezel compensation so pictures are not hidden behind thick monitor
bezels. Wall layouts can be saved and loaded as templates (XML).
Currently playing windows are moved onto the wall without being stopped. Up to 4 monitors are supported. Exit with Esc, the Exit Wall button, or the context menu Exit Video Wall; streams return to the main window automatically.
