Just upgraded to Sky Q - only have a 1080 42 inch TV - same TV, same HDMI lead - Sky Q picture is softer and colors washed out compared to picture from my old Sky HD box - new box is 1TB UHD ready box. Have set Sky Q to 1080i. Read on Sky forums lots of others have noticed same - picture on Sky HD was great, then 'upgrade' to Q and its noticeably worse. This is watching HD content - I did not sub to UHD or HDR as my TV does not support it. Are Sky Q boxes somehow set up to look best with OLED or something? My TV is a 5 year old LCD model (Sony). As I said, Sky HD looked awesome. Now with Sky Q the image is much softer and the colors a lot more muted. Now don't get me wrong, I don't want in your face neon TV showroom color and contrast and sharpening artefacts, but I was not expecting this.
