Subject :
	MST mode / 4K monitors no display

Description :
	When connecting CS1924 to one monitor, 4K@60Hz output works fine, but if two or more monitors connected to the KVM Switch, the display is lost after 5-6 iterations of switching between display ports. Usually results in a black screen, and then after refresh causes a resolution change in the monitor. Each experiment was tested with both the stock firmware, and the latest firmware (v1.1.104) as well as the cables that were provided in the packaging.

Solution :
	DisplayPort 1.2 doesn't support daisy chain monitors if the output resolution is 4K@60Hz due to bandwidth limits. Please use 4K@30Hz output instead. The detail please refer to the DisplayPort Official website . https://www.displayport.org/cables/driving-multiple-displays-from-a-single-displayport-output/
