I have got an dual monitor issue that has stumped everyone I have tried asking about so grateful for any new advice!
When I try hooking up 2 monitors to my video card (ATI Mobility Radeon 7500), both monitors display the same content. Instead of being an extension, the second monitor just duplicates what's on the first screen.
I've tried to change the display in the Setting tabs on the Display options but to no avail. The dual monitor icons are displayed and it does let me click on the second monitor icon and allows me to do both of the following :
Right-click and select "attached" to activate it
Or check the "Extend my Windows desktop onto this monitor"
However, after then clicking "Apply", and allowing the machine to accept the settings, the computer appears to be accepting the settings - but then just reverts back to duplicating the info from the first screen onto the second monitor.
When I bring up the Settings again to check what's happened the second monitor is again not active anymore. Even when I move the two monitor icons around, and then it ask me that it will activate the second monitor for me, and I reply yes, the problem still does not go away - and the settings revert back again.
I think the issue is that the computer thinks that both monitors are the same as when I press the Identify button both monitors are identified as "1".
I'm sure I am using the correct cable and connections, and a compatible graphics card - otherwise I would not be able to see the same info on both monitors - right ?!
Do I need to update my drivers ??!! Please somebody help!!!
