LUMIX Tether Black Screen / No Live View — Fix in 5 Steps

This is a focused fix for one specific LUMIX Tether problem: LUMIX Tether Black Screen / No Live View. Walk the list top-to-bottom — the first item is the most common cause in support tickets.

Root causes, in order of frequency

1. HDMI output set to External Recorder
2. GPU driver too old (Intel UHD < 2024)
3. USB mode left on PC(Storage)
4. Second app holding the camera (LUMIX Sync, OBS UVC)
5. V-Log without a LUT applied on the preview

Confirm the fix

After each step, close LUMIX Tether completely, unplug USB for 5 seconds, replug and relaunch. The connection state is cached — without a full power-cycle of the link you cannot tell which fix worked.

Still stuck?

If none of the above resolved it, swap the cable for a known-good USB 3.2 Gen 2 cable (this fixes ~40% of remaining cases) and reinstall LUMIX Tether v2.12 from the main download page. Related: Windows 11 install guide. troubleshooting guide.
