Hi there - Posting on the Inspiron board as there is no Precision board it seems. I have a Dell 3510 that has HDMI port and when connected to a 3580x2160 monitor works fine. Now enter a port replication (docking station) that has a DisplayPort and DVI connector (but alas no HDMI port). When i connect the monitor i can only get 1980x1080 resolution. During one reboot when the DVI cable was being used the monitor showed 3580x2160 but now i can't get it to display with that resolution again. When you right-click on the desktop and select the Intel graphics settings it recognizes the second display but only provide a maximum 1980x1080 resolution setting. There is a "customize" your own resolution but when i enter in any resolution above 1980x1080 is says its not supported. What am i doing wrong?
