It's cool I like it, but seems a little overkill on the HW. no matter. One thing though, how is the screen 1080px1080 ? Is it a 1080p square, with the visible pixles a circle cut out of that ? I doubt it's a non rectilinear pixel grid. i guess it's x y coords, rather than cartesian ?
It is logically a 1080x1080 rectangular display. Every pixel outside the circle is ignored.
