Troubleshooting
Why am I not able to display resolutions of 4096 x 2160 @
30 Hz?
A. Click [Display Setting] > [Advanced Display Settings], then
choose the desired resolution manually.
B. Ensure the device, display and cable all support 4096 x 2160
@ 30 Hz HD.
Why does my PD charging time vary?
The upstream device (laptop) will auto-adjust the power input
based on the battery level at that current time.
Why won't my HDMI, Mini DisplayPort and VGA displays
show different screens?
Most MacBook laptops do not support MST, allowing you to
extend only one screen and mirror the other.
