I have 3 monitors and want to have joined only two. However it's not possible 4 me (please, advice, if I am wrong). Each time I need to unplug the cable from the 3rd one to make it working OK. Only eyefinity quick setup and all in row (and switched off one too - cable unpluggung needed). As I remember, in old drivers it was possible, but now. Please restore flexible eyefinity setup, I see, that many questions, like this, are present already
