How to best do 4 HDTV's from one PC?

post #1 of 6
Thread Starter 
Hey guys,

Our office is looking at mounting 4 HDTV's vertically across the main wall in our office.

The idea is that we will have one PC driving them, and all they will do is have a full screen Firefox window open, displaying content from 4 different webpages.

The HDTV's are 1920 x 1080 resolution and have HDMI inuts.

The main question I have is what the best way to drive these 4 screen from a single PC.

Graphics cards with 4 HDMI outputs are too expensive.

I was thinking perhaps a graphics card with Dual DVI-I outputs and then 2 DVI-I to HDMI splitter cable like this might work?

http://www.ebay.com.au/itm/Astrotek-DVI-I-Male-to-2-x-HDMI-Female-video-splitter-cable-0-3m-/390466309289?pt=AU_CablesConnectors&hash=item5ae99b0ca9

Will these splitters allow the 4 screens to display different content?

Is there a better way?

Will there be any issues using 15 -20m HDMI cables?

Cheers guys

You will need a GPU with 4 separate outputs. Most cards anymore have 2 DVI, 1 HDMI of sorts and 1 DisplayPort of sorts. Then respective adapters on them to get HDMI cable compatibility.

The splitter you have pictured would just duplicate the output provided by a single DVI output.

There isn't a whole lot of description on that splitter, but I am willing to bet it will only duplicate the image that it is given. Is said pc capable of housing two low end video cards?

Ahh ok,

So a GPU like this one

http://www.mwave.com.au/product/sku-aa78470-his_radeon_hd_7770_icooler_video_card_1gb#detailTabs=tabOverview

1x DVI, 1x HDMI & 2x Mini-Display Port

Is there any way I can get a DP to dual HDMI output adaptor?

Hmm. Description on that card says it will support up to 6 monitors but you will have to use a dongle http://www.amd.com/EyefinityDongles unless the tv's have display port (unlikely). But yeah, should work.

With that 7770, you would need:

Two of these Mini DP to HDMI adapters and one of these DVI Male to HDMI Female adapters.

You would of course have to search via your local means instead of what I've provided.
