I will soon purchase a Plasma TV. It will can also act as a computer
screen. I am thinking of taking an old PC CPU and basically loading
it with Power Point and continually run a PP show on the Plasma, and to
2 other Flat Screen displays, one in the kitchen, one in the study.
(burn in not an issue, since it will be constantly changings, screen
life is something I still need to research)
Questions:
Can you easily split a Computer Screen Signal 3 ways.
Can you send that signal a distance (25 feet)
What wire would you use, I do not think I want Coax or RCA Jack,
unless there is a cheap converter from Computer Monitor signal (RGB I
think) to RF for Coax or to RCA Jack.
I have my first floor currently torn out back to the studs, so now is
the time to put the wire in.
Ideas
(I plan to run family photos on the screens, maybe some motivational
messages, or even countdowns to Christmas, start of school, stuff like
that. Just for fun around the house)

I don't know about the cable specs but we have 3+ flat screen monitors
in the lobby of my office that run the same powerpoint presentation so
I believe it can be done. They are all more than 25 feet apart so I
don't think distance will be an issue.
As for burn-in, watch out for burn-in that could occur if you use the
same powerpoint template/background for your slides. The template used
for the powerpoint slides at my office have a red stripe on the left
side of all slides. Even though the text and images in the main area of
the slide are changing, most if not all of the slides have the red
stripe, and the screens show some burn-in from that.

No, but you can easily buy a three (or four) output graphics card,
or install a couple of dual-head capable cards in the PC.

Depends on the resolution. 25' should be possible, at least at
lower resolutions.

VGA or DVI.

A VGA splitter and amplifier isn't cheap. A quick search turned up a
1->4 VGA splitter for around $450. (I did a search for VGA digital
amplifier, which is equipment I've seen used to split a VGA connection
from a source computer to 2 projectors).
If it were me, I'd probably look into getting an old ATI All in Wonder
Pro or something like that, and get something like
this:http://www.hometech.com/video/amp.html to broadcast the signal to
the other TVs.
I currently use an ATI AIW 7500 on my TV (through S-Video) as my
primary monitor, and it works very well. Pictures display very nicely,
even if not to the best resolution.

FWIW:
I have a plasma monitor in the living room along with a good audio
system. A media PC drives the monitor through a DVI cable (the only
way to go - and get a video card that will match the screen's
resolution 1:1).
When I'm not watching a movie, I use Winamp for general music. This
would burn in the screen in a big hurry (even with a screen saver), so
I leave a laptop computer in the kitchen to control the media PC
through a VNC remote desktop connection (I've wired ethernet into every
room, but wireless would work just as well). The plasma screen stays
turned off but I control the PC from the laptop in the kitchen.
Anyways, both screens show the same thing all the time. You could do
this wirelessly, or run some Cat5 while the walls are open. This
involves having a PC at the location of each monitor, which could be a
good or a bad thing. There are some really compact PCs available.
By the way, I've observed so far that burn in on plasma screens seems
to be cumulative. Even with a 1 minute delay on the screen saver, I've
already managed to leave some lasting marks on mine. An LCD is really
more suitable to what you're trying to do.
