Over the cable

Using the settings without Wi-Fi at all, from Chrome or Edge on a computer.

What the settings page does, the display can also do over its USB-C port, with one exception noted below. The Connect page on this site uses that, so a display whose Wi-Fi is the thing that is broken can still be fixed.

What you need

• A computer running Chrome, Edge or another Chromium browser. Safari, Firefox and phones cannot open serial ports.
• A USB-C cable that carries data. Some charging cables do not.

What you can do

• Everything the display’s own settings page does: calendars, colours, the layout and the refresh times, with the live preview, and saving them.
• On a display that has no network yet, give it one: the page shows the same first-run screen the display would, and follows it onto your network.
• See what the display reports about itself: its signal, its address, why it last restarted and whether its last refresh worked.
• Clear a forgotten settings password, keeping every other setting.
• Watch its console while it tries to connect, which says why when it cannot.

A settings password does not apply over the cable. Whoever holds the cable could reset the display anyway, so asking would only be theatre - which is also why this is where a forgotten one is cleared. Only clearing is free: changing it to a new password still asks for the current one.

What is different over the cable

• Firmware can be updated from the service only while the display is on your Wi-Fi, because the display downloads the update itself. It cannot be installed from a file: the cable carries text, not a firmware image.
• The display’s own page keeps a copy of your settings in the browser in case an update loses them. This page does not, because it is not tied to one display.
