Monitor not displayed through Displayport NVIDIA

[betlolecols]

Hi everybody!


I've recently got two monitors, but the secondary monitor doesn't show anything. I have a NVIDIA Quadro 4000 with 2 Displayports and 1 DVI. The Monitor is a Samsung S22D300 (both of them).
When I connect the monitor through the DVI connector it works fine (with both monitors) but not with the Displayport (none of them). What can I do?!

I have tried already to unplug and plug again. install newest drivers from Nvidia... AHHHHHH!!! help!

Hi,
Did you use the link my display is not shown ?

 

[betlolecols]

yes I did. Is searching but not finding anything....

it has to be something with the displayport connector I think, but I don-t get to make it work...

Hi,
Try winkey+p and see what appears
I would usually start with choosing duplicate
Otherwise yea could be a bad display port
Personally I have not connected 2 monitors via display ports yet might try in a bit to see what happens.
I'm using 372.70 NVidia driver which one are you using ?

HI,
I am using the 375.63. I think is the newest one

when I press Win+P I can switch it to Extend but still no signal on the display... Windows should first recognize it... I guess

Hi,
Nvidia Quadro 4000. Displayport problem - YouTube

 

[betlolecols]

yes! that is exactly what it happens. No signal with the displayport, but no problem with a DVI connector...
