Tri TV setup, multi HDMI possible?

Hey guys.
So i want to set up a Tri TV setup. I have three 40" TVs that have HDMI as the main input (it has others but not up to par with PC standards, so it is VGA and Composite) and i want to setup my second PC as an Media Center/Guest rig. the TVs i have not decided if they will be split between 3 sections (wall, desk and near second PC) or all together like you would a work station setup. But is it possible to get a PC working all HDMI when i only have 1 HDMI slot on the GCARD?

Sorry if this is also in the wrong section, please move if i am and if possible! many thanks!

I can show pictures of the Televisions if need be!

If you want the same picture repeated on all three TVs then Yes. That's a bit like Clone mode with a dual output graphics card, but it's achieved using a simple HDMI splitter.

But if you want to spread the picture across three screens like an extended desktop then No. You'd need a new graphics card with multiple outputs or some other way to generate the segments of an entire ribbon of desktop across three different screens.

Would a system like, Display Port to HDMI, Mini HDMI to HDMI cables work in this case ?

If your graphics card has multiple outputs and the software and drivers support multiple monitors then sure. I've been running multiple monitors from desktop PCs for the last dozen years or so. It all depends on the capabilities of the graphics card. For example, a graphics card with just a single DisplayPort socket can be used with a DisplayPort Hub to give an extended desktop spread over three screens. Read THIS then look at the DP Hub that Overclockers sells HERE

The TV side of things is relatively straight forward. The inputs are HDMI. If the TVs have a PC mode then use that. If not then you should try to switch off any overscan either with a dedicated menu control or by checking which of the TV's aspect ratio options maps the 1080p incoming signal as cleanly as possible.

The rest of your questions are probably better asked in the GPU (Graphics Card) forum since it is the graphics card and its connections where most of your questions need to be asked.
