Detects Display But Blank
 

Hi I am using two external monitors HP 2511 and HP 2311x and it was working fine till yesterday night when i installed 1.7 (previous had v5 beta). After that i did uninstall 1.7 and reinstalled v5 beta but now i don't see anything in the display but its detected.

logs Attached
 

Attaching the details.

More info
 

i had connected my displayLink to a high speed USB hub.
now i have disconnectd and connected back to the mac native ports

Black Screen
 

On the last beta and the release Version of 1.7 I don't see a screen. The second monitor (2 Apple Cinema Displays) is detected, but the display stays black. Rebooting, reinstall etc. did not solve the problem.

Debug Info
 

Attached you find the debug info... by the way - the problem occurs since Beta 5 (b5). I hoped it is fixed in the final version, but does not seem to be..

An option which didn't work for me
 

This did not work for me but just found it somewhere else



Unplug the adapter from the USB port.
Disconnect the DVI cable from the DisplayLink adapter.
Power off the display you normally use with the adapter.
Connect the USB cable between your computer and the DisplayLink adapter.
Wait for your displays to flash (as if a new display was connected).
The light on your DisplayLink adapter should be on now.
Connect the DVI cable to the DisplayLink adapter.
Wait a few seconds and then power on the display connected to the adapter.
If this process doesn't work, try a reboot and repeat the process once Finder finishes starting up.

No success
 

I tried your process and it still didn't work - sorry. I tried it several times.

Yeah
 

that link did not work for me too. Just wanted to put it out there just incase someone else finds it useful.:o

Thanks for your report and the logs. Could you please uninstall 1.7b5 and reinstall 1.7 and collect the logs once again (use VERBOSE as verbosity level as before). Thanks

Thanks for debug info. Could you please change the verbosity level to VERBOSE (menu advanced->verbosity) and re-collect the debug info (unplug and replug the adapter before collecting the info). Thanks
