    I did some more experiments with Line 4x mode, and I think I found the optimal settings:

    Line 4x (Generic 4:3)
    H. samplerate 1560
    H. synclen 72
    H. backporch 170
    H. active 1280
    V. synclen 3
    V. backporch 30
    V. active 270

    Mainly what I did from defaults was decrease V. active a little bit, and then centered the picture with V. backporch.

    This gives a “4:3 1080p” mode that the 4K TV handles optimally (scaling and motion).

    Picture was a bit dark now, so I Increased brightness in OSSC a bit from 128 to 138 for all three colors (R/Pr G/Y B/Pb offset)

    Here is some photos of the result (colors are off from camera, doesnt really do it justice):
