Hi Mike,
Actually, adding graphics would have to be done via some method other
than PSET / PRESET. These ROM functions work directly with the LCD
drivers and don't even go through RST hooks to intercept. So they can
ONLY output to the internal LCD. Adding any type of graphics to a
modern DVI solution would involve creating a whole new API / function
call interface.
My original idea for adding graphics to TDock was to add the capability
to AsciiPixels.

Although I'm pretty sure that the answer is as Brian posted, I did
(and still do) want to do some testing on a real DVI as you asked
instead of making an assumption; I thought about the same thing quite
a few years ago and did some investigating, even disassembling parts
of the Disk BASIC overlay, but unfortunately can't find my notes from
that time.
Unfortunately I didn't realize that this was an urgent issue requiring
immediate action and thought it could wait until I could find some
time to dig the DVI out of storage, find a monitor, hook up an
LA, etc. etc.
Sorry you couldn't wait; that's the trouble with asking hobbyists to
do something for you...
I understand that you want a solution that connects through the system
bus and emulates DVI video exactly; I just wanted to display the
M100's screen across the room on a 40" TV while comfortably reposing
an the couch playing games, so I chose the easy way using the serial port.
I thought maybe this would be interesting while waiting for Ken's
complete solution (especially since using the com port allows a
wireless Bluetooth connection), but apparently not, so I was curious
what you and others wanted to do that this didn't satisfy.
As John pointed out it does tie up the serial port, but it seems that
you might also be able to use the same connection with TS-DOS or similar.
BTW, there's also an article in Portable100 about using the parallel
port, but although I happen to have the exact obsolete hardware used
it looked a lot more complicated and limiting.
I'm not sure where you're getting '40 x 16' video as in your other
post; AFAIR it's either the normal 8 x 40 or 24/25 x 80.
One other thing: the DVI is text only; if you're going to the trouble
(as Ken probably will) then you might want to also add graphics (even
if only the PSET etc. functions) and maybe even colour, which will
obviously complicate the situation somewhat.

What's so interesting abou an external screen ? I can hook up a
HDMI 24" screen to my modern laptop, but you don't see me hauling
one around. It is just another thing that makes working on you
computers a bit more comfortable when you're not on the move. You
only use your Model T when you travel ?
The DVI is the old-school equivalent of a docking station or a
port-replicator. Why would it be useless to re-create that with
modern technology, certainly now that 'its so cheap?
Anyway, forget it, forget I asked. I have gotten the impression
that by asking something that doesn't sound useful for the
technical guys, I have irritated those people.
Sorry guys, I won't do it again. Just drop it.

I guess the thing that makes it relatively uninteresting for
me is that you'll have to be tethered to a display of some
kind, which negates the most attractive aspect of the ModelT,
its portability; you might as well just run VT on a laptop.

Well might nice for dev on real hardware. But the only time I do
that is when I’m testing serial port stuff so, yeah.
Which I think is why when we’ve talked about this before the
parallel port seems the better way. But then you need even more
hardware.
