Best Dual Display Solution

I'm going to be making a computer here pretty soon for my work. We just ordered 2 Vizio 42" TV's to put in our foyer. They will just be simply running PowerPoint and the occasional DVD. Nothing too fancy.

Anyways, I need the best solution to send the signal to both TV's. 1 TV is in fairly close proximity to the PC. The other will have the cable run up the wall, across the foyer and down the other wall. Let's say 100 feet for safety sake.

What would be the best way to do that for the cheapest?

Here's my thoughts:

Option 1a: DVI or HDMI splitting (passive)
I was thinking about sending either a DVI or HDMI signal out the PC to a splitter. I found a passive splitter on Monoprice...

...but I'm not sure if that would work or not. I'm not too familiar with HDMI (they also have a DVI version) and if it would cause problems. This obviously seems like the cheapest solution.

Option 1b: DVI or HDMI splitting (active)
Same as option A but use an active splitter. They are just a lot more expensive. I would prefer to spend less and I don't care about signal loss as long as it's not to the un-readable point. If the passive would work, I'd choose it.

Option 2: Dual Video Out
I know a lot of video cards have 2 DVI (or 1 DVI and 1 D-Sub) outputs. I would send 1 to each TV. I'm just not sure how that works on the software side. I know how to "extend" the desktop, but I've never tried to send the same display out both video outs except on a laptop which has a special setup for that since 1 is the internal display.

Option 3: HDMI -> CAT 5
I know the converters are expensive, but is there anyway to multiply the signal to multiple cables? If there is we would want this for future upgrade ability.

Option 4: The one I haven't thought of.
Any other suggestions?


Thanks

Alright, I'm bumping this again. An update is that we decided we are going to keep the TV's fairly close to each other, so distance running is not a problem.

Due to this, I'm adding another possible solution and wondering if anyone knew about this:

Is there some sort of Media Extender that would send PowerPoint to the screens? I was looking at setting up a whole new computer for running the signal, but since this is for a church, I have several computers that could run PowerPoint and/or DVDs during Sunday mornings which aren't being used except on weekdays. I could send the signal via cheap CAT5e cables to a Media Extender and offset the cost of cabling since a Media Extender should be a lot cheaper than a whole new computer. If it has Component Video rather than HDMI, I may even be able to save costs on cabling all together.

Is this a possible option? If so, what products would run this?

How do you clone the displays? I only know how to extend onto two separate desktops (and I'm not currently at a computer where I can test to figure it out).

Not necessarily. On my computer, it saves 1 setting for 1 video port and another setting for the other as I switch between my DVI port and my VGA port all the time for my personal HTPC. When I turn on the computer, it usually auto-detects which port and adjusts the resolution.
