FN + F7 Presentation Director , Display Port

[WarhawkCZ]

Hi There,

can anybody give me an advice about Presentation Director ? I want to use it for swapping between external monitor (Connected via Displayport and reduction to DVI) and T500 LCD.
I managed three profiles :

Only T500
Only External LCD
T500 and External LCD

I set "Show me the Choose Display Scheme menu" when I press FN + F7 but it still switching options in cycle without any menu. When I reboot T500, sometimes it works, sometime not, sometime for a while...
My laptop is clean, because I've got clean instalation of Vista 64b.

Next trouble is with Display Port - sometimes I can't switch LCD. It seems that LCD is connected (maximum resolution 800x600), but Presentation Director show error and standard vista dialog too during operation.

Sorry about my english.
