Hi everybody. - I still have some problems with video image since buying this device (Z9S). Youtbe works fine -I tried the settings shown in another section of this forum and still can't achieve normal picture quality.. It is impossible to achieve a clear image in the video, either foggy or grained. Black is green in some scenes, not black. Tested on two TVs : TLC & Thomson 4K + HDR10, port HDMI 2.0 HDMI cable : I tried 3 different cables (Received with the box, the Zidoo label, and two HDMI premium cetified + chroma) Tested factory reset and different versions of Firmware, the same result. I tired ZDMC, VLC player. I have the following image settings : (The image is either very black or there is a lot of fog. Visually it looks like 6bit, not 10Bit). Video UHD@4K 2160p results: Now I have the configuration: (but I tried all the different combinations) - HDMI range : 16-235 (limited range) - HDR10 - Color : Auto - 4K @2160 60Hz + auto frame for video. - I really do not understand that ATV at half price has a much more accurate and clear picture. Is it a feature or a defective device? Either the film is filled with fog or is very grained. Zidoo test video 1080p : (On another ATV, the same films on the same TV work fine. This problem is only with the Z9S. My second ATV box (S905X + Mali 450) have a sharper and more vivid picture, I do not understand where the problem) Thank you in advance for any advice from experienced users and for any help or suggestion. Thank you.
