Firmware Updates

Symptom:	When using the mirroring function of our product to watch videos on iPhone 16 & 17, the video playback is not smooth and appears to be choppy, looks like "frame-by-frame" motion, and it does not playback correctly.
Cause:	The cause of this type of playback problem is currently being investigated and will be resolved soon.

We sincerely apologize for the inconvenience this may be causing our customers.
