The Sync Box updates its software through the Hue app. Open the app, choose the Sync Box in its settings and check for a software update; independent guides advise installing the latest firmware for the Sync Box, the TV and the source device and then retesting each HDMI input individually, since HDCP compatibility fixes often arrive as firmware. Keep the box online with steady power and do not unplug it during an update. If an update fails, restart the box and router, move it closer to the router and try again.
Firmware can also change how the box behaves with HDR, Dolby Vision or 4K 120 Hz signals, so retest your usual sources after updating. Hue's specification page lists a defined support period of at least 60 months from purchase, so old boxes remain supported for a while.
The checks in more detail
If a problem appeared after an update, note the version and the change and contact Hue support, and check whether the TV or source also updated at the same time. Keep the Hue app and Bridge software updated too, since the Bridge affects sync. If the box never updates on a good connection, contact Hue support with the model and firmware version. Note the firmware version before and after each update so you can see whether it really changed.
An update that fails once often succeeds after a restart. Update at a quiet time. Firmware for the TV and the source can change the HDCP handshake too, so if a problem starts after any of them updates, roll your testing back to 1080p to see which one moved. Hue commits to at least 60 months of support from purchase, so if the box is within that window and stuck, support should help and it is worth contacting them before replacing it.
