What do I do if videos shown via QCast Mirror lag or are choppy?
When videos shown via QCast Mirror lag or are choppy, the most likely factors are Wi-Fi
signal strength or the video bitrate:
• For videos located locally on the mirrored device: The most likely factor is the video’s
bitrate.
• For online videos: The most likely factor is QCast Mirror’s Wi-Fi signal is not strong
enough, it is suggested that the dongle be placed in an ideal location in terms of Wi-Fi
signal strength.
Transmission quality depends on the Wi-Fi environment and the screen mirroring compatibility of mobile
devices from different brands.
