Hi, i just bought a Samsung 4K UHD, model 43RU7172.This is the tv, the page is in romanian, here are the specs : Televizor LED Smart Ultra HD 4K, HDR, 108 cm, SAMSUNG 43RU7172 . I tried to calibrate the image for it for watching movies, bluray, from my pc, but i didn t get to the result i wanted. I ve used the following settings for calibration : from here Samsung NU7100 NU7400 NUxxxx UHD TV series picture settings and tips and from here Samsung RU7100 Calibration Settings . My pc to tv connection is hdmi hdmi, the tv doesn't recognize the hdmi as pc, and if i don't use the input signal plus my pc to tv picture is croped, and i can't use the fit to screen option.I only have two options on picture here, standard and dynamic. The ps4 works with no problem, i just can't get to set up the image setup from my pc.Thanks in advance.
