Thanks for this tutorial post @Goodtime , very helpful!
I’ve got it running at hidpi mode on my iPad Pro 12.9" and headless Mac mini with a hdmi display emulator.
Since changing (from 1600px wide) the pixelation seems to have reduced I think this was at 60hz and now at 30hz refresh rate.
My question is does the resfresh rate the display is set at affect astropad??
