shMatrix try with one of this builds. My experimental build is abandoned for now.
I tried version LibreELEC-RK322x.arm-9.2-devel-20211206125054-c4cb7b6-rk3228a-mxq4kpro.img.gz on my MQX Pro 4k. Everything seemed to work and it goes through the menus pretty smoothly. However, The screen freezes when trying to view HD video through the tvheadend TV client. Any ideas or tweaks I could try?
