As a non technician I am using Ugoos AM6B+/CE/CPM A14 for DV FEL on Sony 42A90K.
When connected to LG42C2 OLED, I had sublime image for DV. After first install DV FEL seemed to look very good on Sony A90K, but after a day/restart I was not thát sure anymore if I was looking at the same quality. I am reading about switching between Standard, Enhanced, and Dolby Vision mode for HDMI, and about different HDMi cables. Is there for the average user a solution to be sure I have 100% quality FEL on Sony Bravia?
