It seems possible, though unlikely, that the firmware might have
something to do with it. The other thing to consider is that ARC is
running at standard VGA (640x480, 60Hz), while SRM tends to default to
something more DEC-like (1024x768, 72Hz, usually), so all the timings
are different, and the SRM mode is more demanding of the hardware.

I've never seen a Multia with this disease though. Are they all the
older VX40 model?
