    Not a typical ambilight - but theres a problem with a lamp I built to display web content using Hyperion.

    There's a web browser on the Pi that displays this simple media: http://itsd.sk/p5js.html

    So it should be displaying a black circle smoothly expanding and collapsing from the center with a white background.

    The media looks like it renders properly on the Pi in the screenshot (bigger image) and the Hyperion test 'dispmanx2png' output (smaller image) at the bottom of this post.

    But the LEDs look like they're zoomed in, as if the scaling/positioning/crop is bad, in the video of the lamp working:

    Everything else seems to work except for the display mapping -

    Hyperion log:

    How might I be able to get the image from the Pi's display(browser) onto the LEDs while keeping the frame centred and uncropped?

    Any questions please ask :)

    EDIT: The problem was a typo of "minimum".... I'll share this project when done!
