thanks for your replies .
My problem appears with static images . I tried "Sharper/smoother" - it does not really help . The slide gets softer and dramatically less sharp , but the moire doesn't disappear . What is really astonishing for me is that---- all the other software products (Windows FOTO , Capture one etc. ) don't show that effect , which for me is only visible in PTE . As soon as I resize the slide / reduce the number of pixels from full frame to eg.1920x1080 px the moire disappears in PTE . Any explanation ?
