Dock Doctor - Diagnose, Fix, and Understand Your Dock

Dock Doctor takes the guesswork out of docked gaming on Steam Deck and Linux PCs.
If you’ve ever dealt with black screens, missing audio, or flaky power after docking, Dock Doctor shows you exactly why - and how to fix it.

It scans your entire setup - dock, display, USB-C cable, and power - and gives you a clear report on what’s working, what’s not, and what to try next.
No more blind restarts or forum diving.
