Using a non-touch Hyperpixel 4 (rectangular) on a RPi 4 and for the most part it works fine. However, on color gradients I get some quite annoying banding. I know it's caused by the fact that the Hyperpixel is only 18bit, but I'm curious if there are any known ways to mitigate this.
Not sure if this matters or not, but my issue is with Chromium, displaying a custom web page I created (as a display for Roon).
Lowering the backlight intensity is one thing on my list, as is adjusting the gamma (although this doesn't seem possible).

I'd love any ideas / pointers on this.
