Default Computer display for the boat?

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???




Well, 40 watts, you wanted help discharging, right?....(c;]

I have two comments that are pet peeves of mine. A boat is a BRIGHT
place to watch TV. Any surface brightly lit radiates LIGHT....duhh...

So, EVERY display on the boat MUST be NON-GLOSSY, NON-REFLECTIVE....so
you're not trying to watch the picture through a damned mirror showing
you YOU and most of the brightly-lit stuff behind you...marina, hatches,
that horrid picture the wife keeps threatening to throw overboard, the
clock on the bulkhead, etc.

THIS is FAR more important than what power it draws. TV is useless if
you can't stand to watch it without waiting for it to get dark outside.

Another issue, on a boat, is "Where are you gonna stow it?" It'd be
nice to have a super 42" beast to watch the movie, but they don't fold
up and stow in the lazerette with the dock lines when you're going to
sea. Oh, they have those stupid swinging mounts that bang the mounted
TV around when you heel over and it slams against the starboard
cabinetry, leaving a gouge, but having a big LCD TV aboard is a real
stowage problem because they're just too big! I wouldn't wanna sleep
with it in the watch berth. So, keep it small, keep it NON GLARE and
keep it LCD. 12-18" LCD high definition TV that runs on 12VDC and has
an XVGA computer input and a NON GLOSSY screen AND NON GLOSSY FRAME
AROUND THE SCREEN (flat black is best!).

That should narrow it down a lot.....




I completely agree about the non reflective screen issue.
I should have included it in the list.

7th pic down...

the screen will fold up under the deck in front of that shelf.
Out of the way, and with a hard cover, should be safe there.

Up there, with a little down angle like you were stretched out
on the bunk, even the mirror surface of my lap top looks great.
All the reflections go elsewhere.

I think 18 inches will be plenty.
But 40 watts! and that's just the display. Doesn't include the
computer or audio amp.

I've got the audio run into the stereo, and the sound is theater
quality - specially in that echo chamber.
