I have a IBM T520 fresh out of the box today. Win7 64bit, SP1 and I just updated the latest video drivers as well.

I have 2 Display Port's and upon plugging in either on the main screen turns black and the cursor blinks rapidly. You can move the cursor around and it work but can't see anything.

The port being plugged in will light up the led on the Display Link adapter but the monitor never receives a signal to warm up the monitor and take it out of standby.

I know both of my display links are good as I can connect them to my old IBM T61p running XP 32 bit and they work perfectly.

Here is the support files as requested in a previous user with both Display Link's plugged in within a minute of each other.

Thanks.
