Hi,

The logs are showing communication errors which are typically due to faulty video cables.

I'd recommend taking a known to work cable (such as that which is connecting your PC to the "primary" monitor) and trying that on each of the three adapters.

Thanks,
James

I am using an all in one system, I do not have any monitor cables...

I have been trying to get Displaylink (Targus ACP71USZ) to work on my Lenovo U530 for the last week now. So far I have done a fresh install of windows 8, downloaded the Displaylink 7.5 M and had the same issue as those listed above. Thinking that it may be an problem with the Nividia driver I first tried to remove the driver. Once again the results were the same, disabled the Nividia video through the Device Manager, and lastly disabled it via the bios and still have the same issue. both the laptop and external monitor flash, laptop screen changes resolution. At this point I'm not sure what to do so Im attaching the Displaylink tool file in hopes that this issue can be resolved. By the way I had it working until I had to reinstall Windows 8 last Friday.
