Dual-Monitors Not Working

[FreakyShotGlass]

I have recently purchased a DVI to VGA adapter for my ATI Radeon 9250 Pro and I have plugged in an old 17" CRT aswell as my 19" LCD. However, although everything is set up to display an extended desktop it is only showing clones. When I drag a window I can move it right of the screen and onto the space that should be my secondary monitor and when I click 'Identify' in the settings tab of the ATI Catalyst software it shows both monitors as Number 1. This is really annoying me and hopefully someone can help me fix this problem.

Hmm, I have suffered problems like this before, and yes, it can be very annoying.

Go into the ATI Catalyst options again, and go to Monitors. You should be able to select each one and catorgarise them. One as secondary and one as primary, and to make one particular one the main one.

I would show screenshots, but I'm afraid I recently switched to Nvidia :(

The options definietly there, and with a bit of tinkering you will find it. I found the ATI suite pretty confusing too.

Its all set properly, the only problem is that even though it detects my LCD on 9250 and the CRT on 9250 Secondary they still show the same thing but its obvious that there is a space where the extended desktop should be. Check out the screenie for a window that has been maximised to fill both monitors, but I can only see what is selected in black, but it shows up in both monitors.

Ah I see what you mean.

I'm afraid I can't be much help now though since I've switched over to Nvidia :(

I can only advise to keep messing with settings to see what you can get. It seems pretty weird for example that on the monitors the drivers showing, they are both the same.

Can you right click them and select anything?

dual monitors is cool...it speed up most of my work, but in rendering sense i notice its a bit slow..maybe because its using 2 resources?Or maybe something wrong with my pc..btw im using Nvidia and its all good.
At first,i got the same problem setting it but actually i miss maybe one process..in the end,i got to use my dual monitor.

the rendering process would slow down on XP. quite simply, the CPU in XP is more dedicated to showing wats onscreen, than a CPU on Vista, because vista uses the graphics card more. its a bit like software rendering for your desktop. basically, its rendering more, because you have two displays, therefor it is taking more time on your desktop, thus giving less processsing power to the rendering process in watever program ur using. it may be good for developing, and editing things, but when it comes down to the CPU work, not urs, then it will be slightly slower.
