New guy on the forum here and hoping someone can help! I just purchased a LG 29um55 ultra wide monitor and it works and looks great when I just use the ext. monitor on it's own and connected to the MS docking station using a DP mini to DP cable, however when I try to set it to see the SP3's and the LG at the same time, they both have black bars on the sides. The LG's resolution is 2560x1080. I was hoping to be able to leave both on at the same time and them both fit the screen properly. When I try to use the extend mode the SP3 looks fine and the LG scales properly but all I have is the task bar on the LG's screen. Any help would be appreciated greatly.
