I have a Dell M3800 laptop connected to Dell USB 3.0 docking station and yesterday connected my new Dell U2515H monitor via HDMI cable to the docking station. I'm running on Windows 8.1 that came with the laptop. Dell Display Manager doesn't recognize the monitor via the docking station (only if I connect it directly to the laptop via DP). That completely defeats the purpose of my docking station if I have to disconnect a number of cables instead of just one so really keen to get this to work properly. I tried installing latest drivers for pretty much all components (at least what I could find on Dell's website) - to no avail. The Display Manager simply refuses to recognize the monitor.
This is extremely frustrating and disappointing, I have all components from Dell and STILL there are compatibility issues. Getting Dell laptop to communicate with Dell monitor via a Dell docking station surely shouldn't be so hard.
Please find attached output from the Diagnostics report - anything here that would explain the issues I'm facing? How to fix it / diagnose further?
