Wireless

projection lag,
large delay
Compared with HDMI cable transmission, the wireless screen projection scheme
itself has the disadvantage of picture quality compression. The scheme itself is a
compromise of picture quality and real-time, and there is a normal phenomenon
in the loss of picture quality. The delay time of screen projection is measured by
the timer, the transmission distance is within 10m, the delay of static projection is
less than 120ms, and the delay of dynamic projection (playing video, etc.) is less
than 170ms, which is considered normal. If the picture is serious, please check the
network connection and antenna connection to confirm that the wireless
transmission link works ideal, and the Wi-Fi band works in the 5G band.
