Customer Display: connected no worky

A-Username — Mon, 17 Aug 2026 05:30:51 GMT

My square register customer display stopped working on a Friday afternoon going into our busy time of week (brewery).

It shows as connected and the backlight is on however, no picture.

Things I tried:

restart

check for updates

restart

send a log to square

restart

Unplug cable and dock display

factory reset

update

same state exists.

was forced to drive to another town to buy a handheld pos to keep my business up and running.

note: display still recognizes touch & I believe CC dunks, swipes, taps just no picture.

was there an update to cause this? Seems like this has happened to others historically.

TIA for any advice!

We went through a Customer Display nightmare a few weekends ago. Looks like you did every single thing that Square Support had me do. Sometimes when I am banging my head against a wall with my hardware, I will contact Square Support via chat and that is excatly what they had me do. The factory reset helped with two of the devices. I even had to factory reset a device that was brand spanking new last weekend. I did have one machine that we could not get to connect and fortunately, it was still under warranty. Reach out to Square Support and be very upfront and let then know exactly what you have done so they don't make you walk through these steps again. Good Luck!

I am having the EXACT SAME issue you describe - did you find a solution? I have also tried everything you listed to fix the issue, with no result.
