    Hi Alberto,<br>

    <blockquote type="cite">I think the driver should only support

    <br>
    Why do you think so?, the 24Hz resolution seems to be the native one
    of the display.<br>

          <div> Mhm, no idea why an interlaced resolution would cause a
            crash. Maybe some miscalculation in the display code.<br>
            <br>
            But apart from that if you just connected your PC to a TV I
            also wouldn't recommend using an interlaced resolution in
            the first place.<br>
            <br>
            See those resolutions only exists for backward compatibility
            with analog hardware.<br>
            <br>
            I think we would just disable those modes instead of
            searching for the bug.<br>

                  well what hardware do you have?<br>
                  <br>
                  Interlaced resolutions are not used any more on modern
