CompatSense answers one focused question: can this dock and this monitor deliver the display mode you need? Sourced from manufacturer and standards-body specifications, evaluated by a deterministic engine, never a guess dressed up as an answer.
What CompatSense is
CompatSense is a compatibility-checking product for display hardware — currently docks and monitors, with the underlying model designed to expand to host devices, cables, Power Delivery/charging behavior and operating-system constraints over time. It’s built around two public tools (the Compatibility Checker and the Bandwidth Calculator) and a growing set of technical guides and troubleshooting content that explains the standards behind those results — DisplayPort, HDMI, USB-C, Thunderbolt, and the bandwidth math connecting them.
Why it exists
Display-connectivity specifications are scattered across manufacturer PDFs, standards documents and forum threads, and most sources that summarize them don’t show where a given number actually came from. CompatSense exists to track every specification back to who published it, where, when it was checked, and how much it should be trusted — and to say UNKNOWN honestly when that evidence doesn’t exist, instead of filling the gap with a plausible-sounding guess.
How results are derived
Every result comes from the same chain: a published source states a specification, the engine derives a capability from it, a fixed rule compares that capability against what you asked for, and the result is the direct output of that comparison — never an opinion inserted along the way. The same inputs always produce the same result. Full detail on the source hierarchy, calculations and confidence levels: Methodology. The devices and evidence behind the results are listed on Dataset & Evidence Coverage, and how sources are ranked and errors are corrected is described in Sources & Corrections.
Scope and limitations
Today, the public Checker and Calculator evaluate a dock and a monitor together against a display mode you specify — not your laptop’s own port capability, not cables, not Power Delivery/charging, not operating-system behavior. The dataset grows deliberately, prioritizing verified specifications over breadth, so not every device is covered yet. No physical hardware testing is claimed unless explicitly stated as such.
Who builds this
CompatSense is built and maintained by Enrique Rubio — the compatibility engine, the dataset, and the editorial content on this site. See Enrique Rubio for background and how research and review work here, and Legal Notice for operator identity details. Questions or corrections: Contact.
