Second external monitor not recognizing HDMI signal from first external monitor

Dell P2723QE

My laptop is connected to monitor 1 via USB-C and is fully functional.  Monitor 2 is connected to Monitor 1 via HDMI 4K Ultra HD cable.  Monitor 2 returns a "No HDMI signal" message and goes into Sleep Mode.

Are both monitors the same?  Daisy chaining monitors requires Thunderbolt or displayport -- HDMI can't be used for daisy chaining.  Some monitors will support HDMI pass through though -- but it sounds like yours does not.

@ejn63​ You're absolutely right.  HDMI daisy chaining doesn't work for my configuration.  I needed to connect HDMI from laptop to monitor 2 and all is well.
