Dell catalog entries include materially different display and port configurations: for example, C2723DEt is recorded as a 27-inch 2560×1440 IPS display with 90 W USB-C power delivery and RJ45, while other Dell monitor models differ. Dell publishes model-dependent built-in diagnostics to distinguish screen faults from computer or cable issues.
