Today, I ran into a bit of a snag with my JSAUX Steam Deck dock. It wasn’t playing nice with my TV, and after messing around for a while, I figured out that the firmware needed an update. Here’s how I went about it.
Getting Started
First off, I grabbed my Windows laptop. Yeah, you need a Windows machine for this – it’s a bummer for Linux and Mac users, I know. Then, I downloaded the firmware update tool from the JSAUX website. This is pretty straightforward, just get the file.

The Update Process
With the tool downloaded, I launched it. It’s a simple-looking app, nothing too fancy. I connected my dock to the laptop using the USB-C cable that came with it. Make sure the dock is powered on, by the way. You’ll see the tool recognize the dock, and it’ll show the current firmware version.
Now, there’s a big button that says something like “Update Firmware.” I clicked that, and it started doing its thing. It’s important not to unplug anything during this part. Just let it run. It took a few minutes, and I just sat there, watching the progress bar slowly fill up.
Wrapping Up
Once it was done, the tool gave me a success message. I unplugged the dock, hooked it back up to my Steam Deck and TV, and boom, everything worked like a charm. The display issues were gone, and I was back in gaming action.
Here’s a quick rundown of the steps:
- Grab a Windows PC.
- Download the firmware update tool.
- Connect the dock to the PC.
- Launch the tool and hit “Update Firmware.”
- Wait for it to finish.
- Reconnect everything and enjoy!
It wasn’t too much of a hassle, honestly. Just a bit of a detour. If you’re having similar issues with your JSAUX dock, give this a try. It might just save you a headache.
