Cant duplicate screens in Windows 8.1

[drumdogg]

Just moved from windows 7 to 8.1 and cant seem to duplicate my screens.

Before I duplicated my monitor and TV, but don't seem to have that option in windows 8.1.

I'm running Nvidia's 327.23 driver for my 2x GTX460s. This is a newer driver than I was running in previous build so don't know if its the new driver or just win 8.1.

Don't seem to have the option in Nvidia control panel or through windows itself to duplicate.

Anyone come across this issue before?

Thanks

I can see the option through Windows:

How are the monitors connected to the PC?

Sorry school boy error!! Was using both cards as output instead of just one!!

Thanks anyway

ps Just noticed that Nvidia released a newer driver there today so downloading it now.
