David,
There are several issues that make PC screens unsuitable for marine use.
There are considerations for power, protection from the harsh enrinment
etc., but a real driver that few people are aware of is night viewing. It is
imperitive that the display dims to black. PC monitors will not. Marine
grade monitors are more money for two reasons. One is certification tests
and the other is durability. Please check out this site.
http://www.hatteland.com/ They make a large majority of the available marine
screens relabled under different brands. If you avoid the commercial
certified screens and go with the yacht screens, you will end up with the
marine performance sans certification costs.

Please also be aware that when interfacing things like black box radars, be
aware of aspect ratio, not just screen size. If the screen size does not
physically match the resolution to be used, circles appear as ovals and that
really looks horrible.

Hi all, different topic. SO in setting up my nav center - Dell laptop
with
SeaClear software... I want to keep the laptop in the cabin so as to
avoid
exposing it to elements... So I was thinking I could find some sort of
waterproof external monitor to run from the laptop to outside the boat
near
the tiller.... Does anyone know of such a monitor for this purpose?

Thanks,
David
