iPad does not take up full external display
My iPad does not take up the full area it can use on some external monitors. While some work as intended, with only space on the sides due to different aspect ratios, some also leave bars on the top and bottom as well, as seen in this image. In this case, it's going to a capture card, but I've also seen it on regular monitors, especially when trying to use powerpoint. Is there a way to adjust display settings like this on the iPad? I haven't been able to find anything but thought I should ask.
Red box is the outline of the screen.
