Optoma Cinemax P1 4k help

My brother gave me this projector since he's hardly using it. I have it connected to my Onn Android tv device.
On the Onn device my settings are
Ycbcr 4:2:2 12 bit
HDR auto
On the projector my input source always says 2160/60Hz no matter what I play from the Onn device. Whether it's YouTube or Netflix or prime, it always shows 2160p.
My HDMI settings are EDID 2.0

I haven't been able to play the PJ in HDR at all and it always says 2160 even on 1080p videos

What am I doing wrong? Thanks!
