Dock Doctor

The release date for Dock Doctor is July 19, 2026, and it will be available for PC. This utility is built specifically to address the technical friction of docking a Steam Deck or Linux-based PC to external displays, identifying the root cause of common failures like EDID mismatches, audio routing errors, and power delivery negotiation failures.

Rather than relying on trial and error, the software scans your USB-C cable, dock hardware, and display capabilities to provide a technical report on why a signal is dropping or why HDR isn't activating. It is a highly specialized tool for handheld enthusiasts who want to stop digging through system logs and forum threads every time they connect to a television. By logging "known good" profiles, it allows you to quickly revert to settings that worked previously after a system update or hardware change.

Pick this up if you frequently game in docked mode and need a fast way to fix connectivity issues.
