Input Signal Out of Range (Daisy chaining Display Ports)

I'm trying to Daisy Chain two monitors using this system.

I have a ThinkPad T480 <-- DP mini --> Dell U2717D <-- DP --> HP Z23.

The natural resolution of the Dell is 2560 x 1440, the HP is 1920 x 1080.

Right now with this configuration, the Dell monitor works but the HP monitor says:

Input Signal Out of Range
Current Mode: H = 88.9 kHz, V = 60 Hz
Change Mode to: 1920 x 1080 60 Hz

In the display settings, the HP monitor is not detected. I have tried changing the Dell resolution to 1920 x 1080 (and lower than that), but nothing changes.

How can I configure the monitors so that they both work?
