ERROR_GRAPHICS_EMPTY_ADAPTER_MONITOR_MODE_SUPPORT_INTERSECTION
ERROR_GRAPHICS_EMPTY_ADAPTER_MONITOR_MODE_SUPPORT_INTERSECTION means every candidate was eliminated when adapter target modes were compared with monitor source modes. The monitor may advertise timings the link or adapter cannot generate, while the adapter may offer timings the monitor does not accept.
Compare complete timings and link constraints, not just resolution labels. A bad EDID parse, missing additional modes, pixel-clock limits, bandwidth restrictions, color format, or an incorrect target-mode enumeration can empty the intersection. Testing a lower resolution is useful only if that exact mode is present in both sets; forcing an arbitrary mode can produce an unstable or blank display.
Build a mode-intersection report
- List every monitor timing and the descriptor block that advertised it.
- List adapter target modes after topology and bandwidth constraints.
- Record the rejection reason for each candidate pair.
- Check whether a known-safe fallback mode was intentionally omitted.
