Windows 7: Secondary monitor not displaying

Secondary monitor not displaying

I have seen a couple dual monitor problems on this forum, but no solutions for my issue. I have Windows 7 32 with dual 4850 cards and CCC installed with Crossfire configured. I am using 2 20" LCD monitors, my primary works fine. Windows detects my second 20" monitor and I have set the resolution and that it should extend my desktop but there is no display.
When windows is loading both monitors display the Windows 7 splash page so I know the signal is getting there. Also I have tried resetting the drivers, uninstalling them, etc. At no point have I been able to get windows to display on both monitors. Any ideas?

Make sure the settings are applied correctly in CCC and in Windows. The two could be contradicting each other.

Yeah I thought of that but ccc doesn't offer the same options to configure dual monitors as it does in the xp version I use. This leaves only the windows options to mess with. Also this issue persisted with and without ccc installed, and windows should be able to atleast mirror the monitors without ccc being installed.

You could try (if you haven't already) right-clicking the desktop & selecting Screen Resolution. From here if you should see the 2 monitors, if you right click the second 1 you should get an option to enable. If not you could click 'Detect' & see what happens.

Hope this helps

Yeah I have done every standard/obvious technique I could think of. Ive used dual monitors on several operating systems before. Right now Im booting Vista64/XP32/xp64/ and Ubuntu and I have set up dual displays on each of them with no trouble.
I have used Windows' display features as well as ati's. And I have tired every variation of both.
