A $45 Cable Matters USB-C hub now outputs video to a Nintendo Switch 2 — after a modder reverse-engineered Nintendo’s proprietary dock handshake and flashed custom firmware onto its power-delivery chip. The fix isn’t plug-and-play. It requires Linux, a USB-C sniffer, and willingness to risk bricking the hub. But it works: full 1080p60 output, HDR support (once color-space tagging is corrected), and even an unintended bonus, VRR toggle in system settings, though the hub’s Realtek chip can’t actually deliver it.
The patch is live on GitHub, limited to one specific Cable Matters 7-in-1 model with unmodified stock firmware. No other hubs or docks are supported. And no, Nintendo didn’t approve it. This is strictly a hobbyist workaround, not a product, not a certification, not a retail alternative.
It exists because the official Switch 2 dock costs $125 and weighs 370g. The Cable Matters hub weighs 120g. That difference matters for travel. But it also highlights how tightly Nintendo has locked down TV mode this time around.
Unlike the original Switch, which accepted many third-party docks out of the box, the Switch 2 refuses video until it hears exact vendor-specific replies, a sequence mkopec captured, decoded, and replicated across two separate firmware layers: VIA Labs’ PD controller and Realtek’s video bridge. The first four patch versions failed.
Only version five, matching the official dock’s full device identity, not just its name, triggered video. Even then, HDR looked flat until the second fix adjusted HDMI metadata. That level of precision is why most third-party docks still struggle. Nintendo’s 21.0.0 update last November broke video on dozens of them overnight.
There’s no OTA path for a hand-patched hub. A future Switch OS update could kill this hack without warning. So yes, you can use a $45 laptop hub with your Switch 2. But you’ll need Linux, nerves, and a tolerance for obsolescence.
The patcher went live on GitHub on November 13, 2026.
