I recently purchased a UD-3900 docking station, however, when I connect I use the dock to connect my laptop to my UltraWide LG 34UM59-B monitor, I am only able to set the resolution to 1920x1080, not 2560x1080.
There is no difference in behaviour whether the laptop display is enabled or disabled (which makes sense, as the laptop is not going through the UD-3900). The LG monitor is the only monitor connected to the dock.
This is using the HDMI cable that came with the monitor, which is label as a high speed cable, and if I plug the monitor directly into the laptop, I can set its resolution to 2560x1080.
Am I just out of luck with this product? Would the UD-5900 provide me with the functionality I am looking for?
I appreciate any help I can get on this matter.
Edit: I should mention that I am using this as a full docking station (with Ethernet and USB devices plugged into the dock), so switching to a USB display adapter is not going to be a viable solution for me.
