ERROR_GRAPHICS_VIDEO_PRESENT_TARGETS_LESS_THAN_SOURCES
ERROR_GRAPHICS_VIDEO_PRESENT_TARGETS_LESS_THAN_SOURCES signals an impossible topology count for the operation being validated. A source represents generated desktop content; a target represents a physical or logical output. Cloning lets one source feed several targets, but it does not let several independent active sources exist without enough target endpoints.
Inspect whether the source set includes inactive, orphaned, or duplicated IDs. The problem may be bookkeeping rather than an actual shortage of connectors. If a monitor was removed, rebuild the topology and source allocation together instead of retaining a source from the previous extended-desktop layout.
Topology-count diagnostics
- Enumerate paths and derive the participating sources from those paths.
- Remove sources that have no present path in the proposed topology.
- Check for duplicated source IDs created during retry or hot-plug handling.
- Distinguish clone mode, which increases paths and targets without adding sources.
