CE-22, Amlogic-ne and Amlogic-no should support also 3D with new nightly 20240730.
Except: MVC frame packaging SoC with hdmitx21 driver. These are T7, S4 and S5 SoC. Like as example Amlogic-no and G12B, Odroid N2+ does work fine.
The other modes (F)SBS and (F)TAB are working fine on all SoC.
I am not sure if this hdmitx21 issue will be solved one day or not.
Maybe a new (4k) 3D media format do arrive earlier…
