By default, the Desktop client displays up to 64 resources in the viewing grid. It uses Adaptive Scaling technology to automatically adjust the resolution of these items, which optimizes performance and minimizes CPU usage.

While we recommend keeping the default limit, administrators can change the maximum number of items allowed on a layout.

To change the maximum number of items per layout, you must modify or create the maxSceneVideoItems configuration file.
