Will the uncompressed display target fit?
Estimate resolution, refresh, color, and display-count demand.
Open Display Link Planner →Display workbench
Plan payload, features, compression, lanes, and topology separately.
A mode can fit the arithmetic and still fail because a source, adapter, cable, OS, or display omits the path.
Which segment drops HDR, VRR, HDCP, audio, or DSC?
Check source, adapter/dock, and display declarations.
Open Video Feature Chain →What DSC ratio would be required?
Compare uncompressed demand with link payload and a 3:1 planning boundary.
Open DSC Requirement Planner →Can video preserve native USB 3 data?
Test the same payload against two and four conventional DP Alt Mode lanes.
Open USB-C Lane Planner →Can ordinary MST extend every display?
Screen OS policy, branch roles, display count, and shared payload.
Open MST Chain Checker →What must a multi-display dock support?
Build OS-aware MST, Thunderbolt, USB4, display-count, and USB-graphics checks.
Open Dock Requirement Builder →Does the path need active conversion?
Classify USB-C, DP, HDMI, DVI, reverse, and USB graphics paths.
Open Direction Checker →Why is there no video or low refresh?
Prove a direct path, lower the mode, then restore one component at a time.
Open Troubleshooter →Why does the target refresh fail?
Combine payload, direct/dock, reduced-mode, and feature-chain evidence.
Open High-Refresh Isolator →Can one cable carry video, power, and USB?
Check endpoint declarations and three separate budgets.
Open One-Cable Monitor Planner →
Order: one-stream payload → all streams on the link → optional features → DSC → lane/tunnel topology → host/OS display count.
