Problems connecting 4th display

Hello, I am currently running 3 24" monitors and just got a 42" TV mounted to become my 4th monitor. The problem is, it can pick up my TV as a display, but when I try to extend the desktop onto it, I get "unable to save display settings".

I am running a HIS 7970 that supports up to 6 monitors, I have my setup as follows:

1 monitor running VGA into a DVI converter
1 monitor runnin DVI into a HDMI converter
1 monitor running DVI to Mini Display Port

I am trying to add the TV as a HDMI to Mini Display Port. CCC can pick it up and so can the windows one, but to use it in CCC it only gives me the option to disable one of the previous displays. I tried disabling Eyefinity also but still no luck. Unplugging one of them also enables the 4th monitor immediately. Can someobody explain what I might be doing wrong here? If any more information is needed I can supply.

What outputs are on your video card ?

1 DVI, 1 HDMI and 2 Mini Display ports

That's kinda what I figured but wasn't sure !
I think it could well be the way you are using the outputs.
Too me it seems to make more sense to use the DVI and the two mini display ports for the three monitors and the HDMI for the TV.
Now you're using adapters with every connection and I think that's causing you problems, the way I see it you'd only need two adapters unless two of the monitors have display port inputs then you wouldn't need any !

Ok thanks! I guess I'll have to guy buy some new cables then and give it another try

If anybody else has any other possible solutions I'm always open to hear them

Make sure both the Displayport adapters are active adapters, not passive.

Thankyou! I had a look into that and it seems that may be the fix for my problems!
