Tonight in Redmond Microsoft is pushing out the very first update to the Display Dock used for Continuum on phones. The update takes the firmware of the Display Dock from version 3.0 to version 4.0, and there is no changelog posted yet (but there is a link to a 'What's new' that is not yet refreshed).
Updating the Display Dock is relatively easy and only takes a few minutes.
How to update the Display Dock
1. Get Connected
Users should be connected to the Display Dock through the USB Type-C connector. On the phone, navigate to the Gadgets app and choose the HD-500 listed on the menu.
2. Open HD-500
Once the app is open choose the ellipsis ('…') at the bottom of the display and pick Check for updates
The phone will then take over and download the new firmware and install it to the HD-500 Display Dock. Users are instructed to unplug then the power cord to the Display Dock to refresh the software.
Nothing stuck out as immediately new regarding features although performance seemed slightly better. The update is likely tied to today's Gadget app update and build 10586.29 of Windows 10 that went out earlier this week. We also wouldn't be shocked to hear about some improvements with Miracast support, which like Bluetooth, can be very finicky.
We'll update this article if we learn more. Sounds off in comments if you notice anything new!
Thanks, Show, for the tip!
