I have a hisense h8g, my base ps4 does 12bits of color (obvious banding) at 1080p hdr, my ps4 pro does 8bits color at 4k, is it a hdmi cable issue? I only have high speed (10gbs) ones. Also, since we got a stimulus, should I sell it and buy a Sony x900h? I originally got it for hdr gaming (brightest tv in my area)
