[Newbie]3.3.6 -> 4.2.0: unable to find working Mode parms for NEC LCD1700V

[Michael Sierchio]

I've just upgraded, and have it working fine on my laptop,
but am unable to get anything other than a blank or blinky
screen on my NEC MultiSync LCD1700V monitor.  The old
config, which worked under 3.3.6, is attached.

Any insights into how to make this work?

Thanks,

Michael
