I don't know why you bother to look for DC driven display.. They will be very expensive and as you know rare. I have purchased a
sinusoidal DC to AC converter. It is high quality, electrically quiet and 88% efficient. Your LCD screen needs about 35 watts.
What problem?

We'll have to wait to see what Lary says.

I've been leaning toward a mini-ITX fanless system - with a fan in the case
and a 12 volt power supply.

Heat is nearly as bad for electronics as water.
So we are running in a hostile environment.

The other issue is mounting. An ITX case is small and can be tucked in
almost any corner. The display can be wall mounted.
No need to take up precious horizontal filing space.

The screen is still a problem for me.
I've yet to find one at a reasonable price that runs on 12 volts.

The first flat screen TV's I saw all were 12VDC. Has a brick power
supply like a laptops. Now they all have built in ... progress I
guess.

I wonder whether they are still 12 VDC internally?

I actually have one of those early ones.
It's a Phillips flat screen 4:3.
But the wall wart makes 60 VDC - not 12.

I was sure that I remembered 12 volts..... old age, I guess.

You can get small inverters to make 110 from your batteries. They do
vary a lot in efficiency so it is worth while doing some checking
before you buy, but I used one for years to power a Toshiba laptop
that was my nav system.
