HD5500 Graphics card does not have 2560x1080 resolution option

[dmonty67]

I have a Lenovo T450s laptop.  I am using a mini D connection to an external LG ultrawide monitor.    The highest resolution available via device manager (windows 10)  is 1920x1080.    When I try a custom resolution setting of 2560x1080, it says there is not enough bandwidth.     I was using a Lenovo T440s laptop with the same monitor and cable/adaptor.  That laptop has HD4400 and worked just fine.   I have looked through other posts and can not find a resolution (pun intended) to the problem.
