You will find that finding a 12 V or 24 V DC LCD screen is very difficult at
best. You will also find that when found for marine use, they are very
expensive. There are reasons for this beyond those very valid caveats made
bt Larry. One of which is black is not black. Most screens glow somewhat
when displaying black. Marine screens do not, as protection of night vision
is pretty importsnt on a bridge. But your requirement is not a ship's bridge
and can be met with an inexpensive computer display that runs off AC with
the use of the low wattage sine wave inverters. The good ones do not radiate
and are amazingly efficient. If you want to keep this screen inexpensive,
you may find that you will have to drop your contrast ratio spec of 1000 to
1 to 800 to 1.

While we are arguing about charging the batteries,
how about some help DIScharging them?

I'd like to put a 15 to 19 inch VGA monitor up forward to show charts and
play movies and such.

It would mount up in the fo'c'sle and fold up out of the way when not in
use.
(I'll make a nice fiberglass mount/container for it)

I've been Googling this mess (bo-ring!) for Marine, Automotive, and RV
equipment (and even cheap home computer monitors).

The marine and RV stuff are really expensive. $500 + for a $100 toy.

So far, a raw LCD 15 inch display looks best from the point of battery
usage (12 volt DC, 24 watts).

The 15 inch version pulls about 40 watts (!)

The LED displays are almost all 120 vac devices.



I'd like to find:
SVGA input. Other optional inputs are ok,
but the laptop will be the primary source.
16:9 aspect ratio.
1280 x 800 is the native laptop display.
12 volt DC power
1000:1 or better contrast ratio
5 ms or better grey-grey response time.
for a couple of bucks maybe??

Larry???
