U2417H, three, daisy chain from Latitude 7480, no go
Hi Chris,
I am trying to daisy chain (yes i know how MST and DP ports work) 3x U2417H dell monitors to dell 7480 laptop.
setup below:
laptop usb-c to mDP --> monitor 1 mDP in---> monitor 1 DP out--> monitor 2 mDP in---> monitor 2 DP out --> monitor 3 mDP in.
MST on on the first monitor and off and other 2.
result: windows display settings detects only first two. I can extend the display across the first two monitors. the Third monitor is NOT detected but mirrors monitor 2.
please help

It is not possible to daisy chain three monitors off of a laptop that uses the Intel integrated GPU or Intel hybrid GPU. The maximum will be three total displays = laptop screen + two external monitors
Latitude 7480 USB Type-C out port --> USB Type-C to DP cable --> #1 U2417H DP in port (MST On)
#1 U2417H DP out port --> U2417H DP to mDP cable --> #2 U2417H mDP in port (MST Off)
