A: It may take 15-30 seconds for initiation and connection after the transmitter and receiver are powered on. Please wait patiently. If no images appear after 1 minute, check whether the connection between the transmitter and the player as well as the connection between the receiver and the TV are made properly.

Q: How come the network connection status indicators on both the transmitter and receiver are OFF even after both devices have been powered on?

A: Possibly the transmitter and receiver are too far away or there are too many obstacles interfering with the transmission signal. Please adjust the position of one or both devices.

Q: Why is not my display device receiving any signals?

A: Please check whether the receiver is properly connected to the TV. In addition, check to make sure the input source of the TV is set to HDMI.

Q: I can not hear any sound on the TV

Q: Why aren’t any images output when the transmitter is connected to a Blu-Ray disc player and the receiver is connected to a PC display or projector?

A: Possibly the transmitter and receiver are too far away from each other, or there are many obstacles interfering with the transmission signal. Please adjust the position of both devices. Both the WHDI Dongle and WHDI Receiver works best when they are placed vertically.

Q: When I connect the USB port of the WHDI Dongle to my PC, Windows detected a unknown hardware, is that normal?

A: The WHDI Dongle only uses the USB port for power, and does not require any driver installation on the PC for such purpose. Driver installation is only needed for firmware update and maintenance.

Q: I connected the WHDI dongle to my laptop but I got no signals, why?

A: Some of the notebooks are equipped with hybrid graphics: an integrated graphics from the CPU and an external ATI/NVIDIA GPU. In most cases, the external GPU must be utilized in order to use the HDMI output of the laptop. For some laptops, you may need to switch the power plan within windows from “Power saver” to “Balanced” or “High performance”. For more details, please consult with your laptop manufacturer.
