Smartboard Display/Touch issues

Using the college laptops purchased around 2026, you may notice that the smartboard has pillarboxing, seen as black sections of the screen to the left and right of the image. You may also notice that when using touch on pens on the smartboard, the horizontal alignment is off. This misalignment gets worse as you get closer to the left or right side of the smartboard. Both issues are caused by the same issue. This issue only occurs when duplicating the screen, not extending.

Background

The Dell Pro Plus laptops purchased around 2026 have taller screens than older laptops. This gives the user more vertical screen space when working off of the laptop, but the smartboard does not support this taller resolution.
