Stream Quality & Device Selection for Multi-View Labs

When mirroring many devices, lower thumbnail resolution reduces GPU load on the control PC.

Typical tiers: thumbnail grid for overview, medium for active QA, full resolution for single-device debugging.

Select-all vs subset: operate on one device first, then mirror gestures to a selected fleet if your tool supports group control.

Ctrl+click deselect pattern works in common mirroring tools — confirm in your software docs.

Hardware tip: discrete GPU and 32GB RAM improve stability above 20 mirrored streams.
