Content not in center of HyperPixel 2.1 Round

Support
1

Today tried installing a HyperPixel 2.1 Round in combination with a Raspberry Pi Zero 2 W. The Pi is running a fresh install of Buster. I used the default HyperPixel installation using the hyperpixel2r installation script.

The good news; the screen works. The bad news; the whole screen seems to be shifted to the top. As a result the top of the interface (something like 10 pixels?) is missing. On the bottom it results in a bar of repeating lines of pixels (not sure how to explain this easily).

I’ve tried the following things:

  • Playing with the overscan settings. > No effect
  • Playing with the frame buffer height and width. > No effect
  • Playing with the dpi_timings. > No effect

Is there something else I can try? The pixels are there, and are not broken. The content is just not in the right place.
