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>

<br>
well what hardware do you have?<br>
<br>
Interlaced resolutions are not used any more on modern
hardware, so they <br>
are not well tested.<br>
