My work laptop (Elitebook 840 G5) is connected to Thunderbolt 120W G2 dock via Thunderbolt cable, then running USB-C to DP and DP to HDMI 2.0, into a ultrawide 49" monitor.
The monitor sees the USB-C to DP connection, but does not see a second input, the laptop also does not see I am trying to send multiple displays.
The specs state that the laptop and dock should be able to display 2 x 4K @ 60hz displays.
I have tried to update the dock drivers and restarted laptop, but still second output is not being recognised.....

Since the port connects to a monitor already, a 2nd port from the dock connecting to the same monitor... i don't see how that would work. what is the resolution of the monitor and why are you connecting 2 ports to that monitor?

The monitor is ultrawide 49" (Electriq eiq-49suwd144fshq) with resolution 3840 x 1080. So I am trying to split the screen, with 1 x image on left and 1 x image on right side, as this is what it is designed for.
I was told that I need to feed two inputs into the monitor.
I have previously been able to achieve the two images by using a dual monitor adaptor (thunderbolt to 2 x HDMI), however I was not able to get both images resolution at 3840 x 2160, due to limitations of HDMI ports on monitor, as only 1 x HDMI 2.0, rest are 1.4.
So I then purchased this Thunderbolt G2 dock, as it has 2 x DP outputs, so can feed monitor inputs (DP and HDMI 2.0). However now using this dock, I can no longer get 2 x images working.
