I have a Samsung 42 inch tv. Now when i try to extend the display to all three. It says unable to display. I just read that you need a display port.

You dont need a dp on the monitor, you only need to use at least 1 dp/minidp from your video card. The 6950 has this so you should be fine.

Use HDMI out to your tv
Use a DVI to Dsub for 1 monitor
And 6950 should come with minidp -> dsub/dvi adapter

AMD Eyefinity only supports 2 legacy devices the combinations of HDMI, DVI and VGA. The third/fourth must be DisplayPort (DP).

If your third monitor doesn't have native DP, must use an active DP-to-DVI/VGA adapter. There's no away around this.

Without active adapter, no you can not.

There's no away around this. We can not change the built-in signal output type in the card. This is AMD Eyefinity requirement.

Just to clarify what im saying, is that you can run with a dp adapter that is not active. DP adapter is needed 100%, my above comment was regarding the 'active' part. I know it works because thats how i run.

HDMI -> HDMI
miniDP -> VGA
DVI -> VGA

Just to add, i didnt discover this on my own, I read it on a forum somewhere when i was investigating eyefinity. I setup myself up based on the fact VGA would mean no active adapter, and it works without fault

Configuration #3 is DVI-HDMI-DP

In your case:

HDMI -> HDMI
miniDP -> VGA <------ AMD called it MiniDP-to-VGA Active Adapter.
DVI -> VGA

So, the third monitor must use DisplayPort/MiniDP.

The only card with a built-in DAC or Active Adapter that I know of is Sapphire Flex. Such as Sapphire 6950 Flex.
