HLG/HDR flag not checked on this config, so i cannot say if it play a role, you need to export config when you have that green you mention.Sorry, here is my config. I may have to go ahead and order an ATV4k. Is there a particular feature the Shield Pro would need to implement to work like the ATV4k does in this manner? Or is it the kind of thing where we just need to test after they have done an update.
Also, if I figure out why my screen is turning green when selecting HDR+ or HLG, does this mean the shield pro will be able to process these formats with my JVC RS540? I'm guessing not.
Correction: When HDR+ is selected, it does not allow DV to be enabled on my projector and goes back to the regular HDR support. When HLG is selected, it turns the display green.
Also keep in mind that if you do any edid changes > RESTART YOUR SOURCE, otherwise issue is may be just normal.
I'm not sure about your source question, may be it was for someone else...
