Radeon X300 does not display two monitors
Posted on 2009-07-07
Working with a Dell Desktop - Optiplex Gx280 with a Radeon X300 card.
Trying to get it to work with two monitors.
We have a splitter for the card with the two plugs labeled 1 and 2.
We have two Dell monitors (analog) and two analog (blue) video cables.
When we plug monitor 1 into the splitter connector #1, monitor #1 displays fine. If we disconnect monitor 1, and then...
Plug monitor 2 into the splitter connector #1, monitor #2 displays fine.
Each monitor has its own analog cable... and the above exercise tells me that both the cables and monitors are functioning fine.
HOWEVER, when we plug Monitor 1 into spltter connector 1, and monitor 2 into connector 2. Only monitor 1 lights up.
If we reverse the connections on the spliiiter (monitor 2 into plug 1 and monitor 1 into plug 2)... only monitor 2 lights up.
When I right click on the desktop, it confirms that I have already selected "extend my Windows desktop onto this monitor.
Also, from a remote connection, I can see the two monitors fine... which tells me the Radeon card is working fine... it is the hardware, or software of the radeon that is affecting the connection of anything to the number 2 port on the splitter.
Is there another suggestion somewhere?
