Can my Dell E5440 drive a 2560 x 1080 display through the docking station?
I have a Dell E5440 laptop issued to me at work. I added a Dell Latitude E Series PR03X Docking Station and recently replaced a 1920 x 1080 monitor with an LG 29UB55-B 29" UltraWide monitor with a maximum resolution of 2560 x 1080. The docking station has two ports, a DVI port and a DisplayPort. I discovered pretty quickly that the DVI port is single-link since my external monitor's resolution maxed out at 1920 x 1080. I ordered a DisplayPort cable in the hope that it will support the monitor's full resolution, but this question occurred to me:
Can the E5440 support an external monitor at that resolution? It used two video solutions, the Intel HD Graphics 4600 and a Nvidia GeForce 720M Discrete Graphics Card with 2 GB of RAM.
It uses two video solutions, the Intel HD Graphics 4600 and a Nvidia GeForce 720M Discrete Graphics Card with 2 GB of RAM, and apparently switches from one to the other depending on demand. My research suggests that both can support the resolution I need, but only through a DisplayPort. Of note, the laptop itself doesn't have a DisplayPort, but the docking station does. I don't know if that is a problem or not.
Is anyone else out there successfully driving a 2560 x 1080 monitor with a Dell docking station and laptop?

Thank you for your message.
This system does support a resolution of 2560 x 1080.
The maximum resolution supported by the Intel graphic card is 3840x2160.
As you mentioned, you have a switchable graphic card. When there is a graphic intense application used, the system will automatically switch to the discrete card.
You can also manually set the application to automatically open with the discrete card.
You will need to use an HDMI – Display port adapter.

You are correct - I purchased a DisplayPort cable and the monitor automatically adjusted to its highest resolution. Thank you for your support!
