2. Why cannot cast a screen through HDMI port?
Select a proper HDMI signal source. For example, monitors or TVs
normally have HDMI 1 and HDMI 2 input labeled. For LG displays, go
to Settings > Input > Input List > Select HDMI1 or 2.
3. Why is the resolution not up to as the advertised?
This HUB is compatible with DP1.2 and 1.4, but the actual resolution
ratio depends on the hardware of the connected device, if the con-
nected device (laptop, HDMI cable, display) can't meet the promoted
resolution ratio of this product, then it can't project with the highest
resolution ratio.
4. Why is the product hot during operation?
a. It is normal for the HUB to generate heat in the process of operation.
b. The HUB has a built-in chip. The more types and quantity of
interfaces a HUB has, the stronger processing power and more heat
the chip delivers. Shells made of metal materials has better heat
dissipation to prevent the chip from overheating, causing the instability
of the HUB or failures such as disconnection.

This form is compiled in accordance with SJ/T 11364.
O ： It indicates that the content of the harmful substance in all homo-
geneous materials of the component is below the limit specified in
GB/T 26572 standard.
X ： The content of harmful substances in at least one homogene-
ous material of this part exceeds the limit stipulated in GB/T 26572

Warm Tip: The 10-year icon refers to the "effective life of environmen-
tal protection", not the product quality assurance period. Electronic
products all contain harmful substances such as lead, mercury and
cadmium. Once they are overused, harmful substances may leak or
mutate, cause pollution to the environment, or cause serious damage
to people and property. The term of "environmental protection use"
means that all electronic products will be required to use within this
effective period. We will no longer be responsible for the quality of the
products due to the safety risks that arise after the safe use period.
