Warm Noted :

If your connected devices and cables can't access 4K@30Hz, the resolution will not be 4K.
If the resolution of the 4 monitors is different like 720P and 1080P, it automatically outputs the lower resolution 720P on 4 monitors. So 4K monitors are prefered as this splitter is 4K splitter.
Mirror/duplicate mode(A-AAAA): 4 screens show the same image, it can't support extended 4 different screens.
Extend Mode (A-BBBB): When using a Laptop as an input, you are allowed to operate your laptop individually when the all 4 output are displaying.
