Nvidia Quadro 4000 for Mac 50Hz???

[Oscar Jimenez Casabella]

2 outputs, 1 DVI I can select it at 50Hz and OK, and another one DisplayPort that I only can select it al 60Hz and I need it works PAL 50Hz.
Does anyone have any solution besides changing the graphics card?.
Thanks!

What's the device connected to displayport? Maybe it's not support EDID 50Hz?

When I force operating at 50Hz with a edit the Mac recognizes 50 ok but the output is blackout.
