I have two graphics cards in my Windows 10 Machine.
Before I upgraded to Windows 10 over 6 months ago I was able to run 3 screens from the two cards.
The Two cards are a AMD Radeon HD 6450 and 6530.
Since the upgrade I have only been able to use one graphics card at a time so am limited to just the two screens. I keep looking for updates or solutions every now and then but keep coming up short.
Windows can see both cards, as can the AMD Catalyst control centre, however, I just cannot get more than the two screens on one card to work.
Therefore thought I would ask on here to see if there is something I am missing. Any suggestions gratefully received.
More information would be useful to determine the root cause.
What driver version do you have installed ?
How are the monitors connected to the cards - what port on the card and what port on the monitor ?
