    4k@34Hz
    4k@36Hz
    4k@39Hz
    4k@41Hz

    Or similar fractional refresh rate, but with integer pixel clock.

    I did not try all of them, but the TV does not seem to like any. "DVI" input port did not help.

    I am trying to max out HDMI 1.4b (or 1.3) and DisplayPort 1.1.

    I tried making BOTH MHz and refresh rates integer with no luck.

    Partial success.

    The maximum I could do for both HDMI 1.4b and DisplayPort 1.1 was 4k@31Hz.

    Just by reducing the front porch from 30Hz.

    The TV does not seem to like any of the 3 kinds of CVT timing.
