Need some help figuring this out. I have 2 1920x1080 monitors 1 2560x1440 monitor I want to use with my 7510 w/ Quadro M1000M card and work issued WD15 dock (not using laptop screen). With my work Latitude 5400 (UHD graphics) I am able to do the 2 FHD monitors hooked up to the dock and the QHD plugged into the HDMI on the Latitude. But when I try that set up with my 7510 it will only recognize the QHD attached with the HDMI and not detect the monitors attached to the dock. If I unplug the HDMI, then it will detect the monitors through the dock but won't do both dock and HDMI like the Latitude. Anyone know why the Latitude will see all 3 but the 7510 won't?
