Questions and answers 

Q1:  No Video/Bad Video or Incorrect Video/Video Stuck 

A1:  This device will take about 25 seconds booting time after plug in 

the main power if all connects are OK, then you should see the 

signal on the TV on both Transmitter and Receiver

 

A2

:  Please make sure the HDMI in/out are connected correctly, if 

above connects are OK, then make sure you are using the HDMI 

cable inside the gift box, which provides noise reduction and 

shielding, and no noise will affect the wireless transmission (be 

sure to use the cable from your media source to the Transmitter 

HDMI IN interface) 

 

A3

:  Please check whether the HDMI-in source is OK by connect it 

directly to TV

 

A4:  Please make sure the HDMI-in is connected, otherwise no signal 

will output and the TV may stay in blue screen on both 

Transmitter and Receiver 

 

A5

:  If above still not OK, please check the video source resolution 

and if it is supported by the device. Please refer the specification 

for supported resolution. If not, please set to right resolution 

according to the specification 

 

A6:   The device is using 5GHz WiFi connectivity, which will be 

interfered by other wireless devices, like WiFi router or 

microwave. Please place the Transmitter/ Receiver at other 

location with less interference and check again

 

A7:   Try another HDMI cable with good shielding since sometimes 

some cables may have compatibility issues

 

A8:  If problems still not solved, please restart both Transmitter/ 

Receiver and try again
