designed around the 3.3 volt logic family, then
the sync inputs must be 5 volt tolerant.

TTL input loading shall be equivalent to one TTL
input load. When logic 0 is asserted by a sync
input, the maximum current source from any
single monitor sync input to the driver is 1.6 mA.
When logic 1 is asserted, the maximum current
source from the driver to any single monitor sync
input is 400 mA.
1.4.6 Abnormal Signal Immunity
The monitor shall not be damaged by improper
sync timing, pulse duration, or absence of sync,
or abnormal input signal amplitude (video and/or
sync too large or too small), or any other
anomalous behavior of a graphics card video
generator when changing modes or when any
combination of input signals is removed or
replaced. Additionally, under these conditions,
the monitor shall not cause damage to the driving
source.
