Hi Paul,

Yes, it is odd! I’m not sure about the driver i have. Do i have to remove the previous driver to install a new one, or can i just click on “update driver” in windows display task manager?

I succesfully installed 3 monitors using the 2xDVI’s and DP ports in eyefinity mode before.
The reason i purchased the 1.2 MST is in order to run a 4th one. Since i haven’t been able to, i disconnected everything and just tried to connect 2 screens on the DP port with the MST 1.2. At that point i realized that neither the display control panel nor Catalyst identified them as two different signals.

Regards,

Laurent
