USB-C Power Delivery & PPS
Fixed profiles, PPS ranges, current requirements, complete chains, and shared-port tables.
Charging workbench →Decision bench
Choose the check that matches your decision.
Each result separates calculation, declared fit, missing evidence, and what a browser cannot observe.
Eight workbenches
Enter through the system you are planning.
Tools can appear in several workbenches when a dock shares charging, data, display, and tunnel constraints.
Requirements, claims, ports, and bottlenecks
Select cable requirements, decode cable and port claims, and screen data paths.
Cable workbench →Feature paths and tunnel budgets
Check optional workload features, shared traffic planning, exact port claims, and isolation.
USB4 workbench →Direction, conversion, and feature chains
Classify active/passive direction and check HDR, VRR, HDCP, audio, and DSC.
Adapter workbench →Payload, DSC, lanes, MST, and topology
Calculate display demand, compression, lane use, ordinary MST, and dock requirements.
Display workbench →Functions, power, data, tunnels, and failures
Build requirements, budget power, inspect shared links, and run direct/dock isolation.
Dock workbench →Switches, splitters, matrices, and mixed displays
Select a topology, reserve ports, screen EDID/downscaling, plan audio, and isolate route failures.
HDMI routing workbench →PoE classes, equipment, budgets, and failures
Match PSE/PD classes, choose switches or injectors, plan total and pass-through power, screen passive PoE, and isolate faults.
