Is there a 'performance' tab hiding in the left pane somewhere? If so expand it and agree to the terms.
If not you may need to enable low level tweaking of the card first before ntune will adjust settings. There was a utility for that on the install CD for an XFX card I recently installed. Coolbits I think it was called? It was a reg edit.
Not sure about the monitor. On the last system I built nvmonitor blue screens. Works OK on my current rig though.
