A movie-nut friend tried one and a 17" flat panel on his computer for
DVD viewing on his boat - he returned both as the blacks weren't black
enuf and one or the other had white light creeping ariound the edges
of the screen. We always "view-test" screens with images that have
lots of color and bright images but interestingly, black is hardest to
reproduce and most less expensive flat panel screens have lower
contrast numbers - 300 to 1, not 500 or 600 to 1 that it takes for a
good movie image. Another problem is slow response and the ghosting
that cheaper screens are prone to.

I have been looking at the Sharp 15" LCD and it is great in all levels of

While look considering it for the boat, I get to thinking about the
feasability of using it as a monitor for the LapTop.. Anyone have an idea of
this and the hardware involved to do this through the A/V ??

Actually both. Most computer devices and I think at least some of the LCDs
can work on 11-13V, but I am afraid that my supply won't be that stable.
I think that the voltage in my system might vary at least from 15V to 11V or
probably from 11V to 17V.
The lower limit is probably not critical (though someone selling the stuff
told me that low voltage might some how shorten the lifelength of the LCD,
because it might get turned on an off to much). That is how ever I risk I
would take. What worries me more is the high voltage levels. I believe there
is a reason that they sell "vehicle converters" for use in cars, campers and
the likes that converts 11-17V to a stable 12V.
I would not like my gear to melt down if I forget to disconnect the computer
while I start the engine or connect the AC connection.

This was discussed in an earlier thread, but I never reached a conclusion,
and would still not dare to run a system without a "vehicle converter" that
accepts 11V-17V.

I would like to be proven wrong, so I could save the money, but I am not
convinced yet.

The problems I se is: Is your current supplie stabile enough? If not you
might need a 11-17V to 12V converter which might set you back another
50-150$.

I have solved the problem of a stable 12v for my Laptop with a 'brick'
that
was made for the Toshiba (discussed in another thread).
The Sharp 15" LCD comes as a 12-13 vdc unit with a wall wart for domestic
use..

I am currently using a duel power, 12vdc/110vac, cathode type tv now but
it
is only 10" and draws more current than the LCD..

I'm just waiting for the cost of the LCD TVs to come down in price.. The
Sharp 15 LCD is now available online for $490~ and that is $100 cheaper
than
in the discount stores.

BTW. My son is in the industry and told me that several new LCD screen
production plants have been open recently and that production of LCD
screens
is now cheaper and easier than cathode color picture tubes (production
equipment less involved). He expects the price of all color LCDs to drop
dramaticly in the next 2 years.

Whoa, Sport! All you say is oh-so-true.....BUT THE DAMNED COMPUTER
ISN'T A CRAY! If you're jamming up the motherboard with ALL THAT
VIDEO DATA, it's slower than hell while that's going on.....

Now, if you plug in a bus TV card with DirectX access to the video
memory that DOESN'T hog the computer resources with all this video BS,
it uses no computer resouces you can detect.

If you think an external USB TV plugged into the NOTEBOOKS they're
talking about is gonna work great.....you must come from another
planet! Hell, notebooks are ALREADY bogged down. They're running
WinXP!

I disagree with you Larry. Provided the video is sufficiently compressed,
enough bandwidth on the USB bus can be allocated for streaming video in TV
quality.

Even USB 2.0 is too slow,

No. USB 2.0 is 480Mbit/s while the FireWire bus, which is suitable for

We have a Sharp 12V 10.5 LCD TV in our V-Berth. Works great! Has a remote,
also
you can mount it upsidedown and can program it to invert the image. Cable
ready and
we also have it connected to our DVD via direct video inputs.

Another thing that could work for me, on the boat of course, is
12vdc/120vac
small-LCD-screen flat panel TV, cable ready. I've seen ads for one or two,
but know nothing about them. If you or someone else can commnet pro or

would appreciate it.

Please excuse the oversight, but I left out a potentially important detail
for using that Hitachi 15" aux TFT LCD. It needs 120vac. I supplied that
with a small 400w inverter, the same one I use with the notebook's brick.
Maybe everyone already knew that, but just in case. . .

As a matter that will be of interest to some, that particular Hitachi had
fairly low power requirements as those screens go. Net, net if I used it
instead of notebook's screen the additional draw was about 1amp. To make
this test, I removed the notebook's battery.

Mmmm, I can run a video clip on my rather slow computer (450MHz). The clip
is 352 x 288 pixels and runs at 25 frames/second. That is almost comparable
to normal TV.
And we've run some DirectX experiments here which gave full TV resolution at
over 100 frames/sec on a 700 MHz AMD.

Now, if you plug in a bus TV card with DirectX access to the video
memory that DOESN'T hog the computer resources with all this video BS,

Oh I agree. I have run two framegrabbers simultaneously in one computer and
four wouldn't have been a problem too.

If you think an external USB TV plugged into the NOTEBOOKS they're

planet! Hell, notebooks are ALREADY bogged down. They're running

I think the average notebook today is much faster than my computer here :-)

Steve is correct. It has a wall wart for 120VAC. We bought ours at Tweeters
for
a good discount since it was a display model and the packaging had been lost
including
the remote and cables. They ordered all the missing items and
gave us a discount of $350. I suspect they are alot cheaper now though. The
model we have is LC-10A23U-B. Draws a whopping 2A.

Well, USB 1.0 is too slow, full screen was kinda blocky and bad sound sync.
