AH-64D A-A Radar

Even though I have the rectangular radar setting enabled, the Air-to-Air (A-A) radar still appears as a circle, which makes it harder to read because it’s smaller compared to other modes with a rectangular shape. I understand the radar is 360° and can be adjusted, but I find it less intuitive and harder to look at in this format. It would be much better if the A-A mode also used a rectangular display, consistent with other modes. Thanks!

As far as I’m aware of, you cannot change it because the radar has the ability to scan 360 degrees.
