I bought the following video card:
I bought this card because I need to extend my windows desktop on 3 display.
Reading specifications on http://www.amd.com/en-us/products/graphics/desktop/r5 it seems that the card support 3 display.
So, I tried the following configuration:
Display #1 - SAMSUNG SyncMaster 930BF -> HDMI port (DVI adapter)
Display #2 - SAMSUNG SyncMaster 930BF -> DVI port
Display #3 - LG W1934S -> VGA port
But windows let me use only 2 display.
I have windows desktop extended on display 1 and 2, display 3 is not active.
If I try to enable display 3, windows automatically disable display 1 or 2.
The same problem occours if I try to enable eyefinity from AMD Catalyst driver.
So, why I cannot use 3 display? what am I doing wrong?
My hardware configuration is:
Asus Rampage II Extreme
Intel i7 920
12 GB DDR3
Windows 7 Professional ITA
Thanks in advance
There are two different types of R5 230, one with a DisplayPort connection as seen in the one in the picture on amd.com which supports three displays. The other type has a DVI/HDMI/VGA connection and supports a maximum of two display connections. This is due to a limitation on Radeon GPUs which can only support a maximum of two passive (HDMI/DVI/VGA) display connections and the third display and beyond must use a native displayport connection, or an active adapter.
