Hi, i am new owner of Z1000 Pro, got it a week ago and still struggling with one problem. I found a lot help on this forum thanks to you and red tons of posts about Zidoo. I have seen some members asking about problem of very dark scene when playing 2160P video (happens both with SDR and HDR). Same happened to me. I tried everything. Switching cables, direct Zidoo connection to TV without Onkyo, changing settings on Zidoo,tv picture settings...nothing helped. My Tv is Sony XE9005 (HDR, no DV), HT receiver Onkyo RZ800 and Zidoo Z1000Pro. Sony TV settings All picture tweaks off, HDR auto,Colour Space auto, HDMI video range - Limited Zidoo settings are at the moment Color - as per HDMI 2.0,HDMI color range 16-235,HDMI Signal format-Standard . HDR- Auto. Dolby vision compatibility - TV Led.MaxCLL and MaxFLL enabled. Custom EDID - disabled. HDCP off. Playback Auto frame rate-Match frame rate only. ZIDOO FW 6.4.20 All the time while playing 2160p content picture is too dark. Same content\movie but 1080p - everything is perfect. Only difference what I saw is when i changed Zidoo setting of HDR to Highest SDR REC.2020 that picture looks better regarding brightness and contrast (little bit washed out) but colours are messed up (too yellow skin tone, etc...). Is there a way to help with some advice? Thanks in advance. Attached is EDID file saved when Zidoo was connected directly to TV.
