Went out and snagged an HDMI to mini display port convertor, and the system is still only allowing two screens to be active at a time. I can switch between the screens, but can't get all three working at once. Ideas?
According to a number of reviews I read, they upped the number from 2 to 3. http://www.pcworld.com/article/2055507/hands-on-with-amds-radeon-r9-290x-gpu.html
In my newest build I went with the amd radeon r9 290x to run my 3 way set up, as one of the promised features was I could use 2 DVIs and 1 HDMI to do so. Plugged in all three and the HDMI won't work. Any advice on how to get this operational?
