will not change refresh rate direct to TV also
I've seen a similar issue on some Gemini Lake boards - https://bugs.freedesktop.org/show_bug.cgi?id=105887
This was a problem with ITE66317 HDMI retimer chip.
NUC11TN block diagram mentions LS/Retimer on native HDMI port. So I suppose it could be a buggy HDMI implementation specific to NUC11TN.
