In HDR mode i watched natural hdr mode in which dynamic contrast is off, actually i did it off. Hdr bright mode it will more bright then natural preset. I think it is enough bright for me in natural hdr mode. My room is well lit but it does not get sunlight directly.
My picture setting SDR and hdr respectively;
Thank you C anatomist
I will try but I don't have HDR Bright mode on my TV,
Maybe it's the problem
