Default Lenovo ThinkPad W520 Windows 8 issue, same dock works with ThinkPad T61 Win 8

I've got a Lenovo ThinkPad W520 laptop, using RTM version of Windows 8 Pro (64 bit) and the new Lenovo video drivers for NVIDIA Quadro 1000M 8/28/2012 9.18.13.614 from:
http://support.lenovo.com/en_US/guid...DocID=UM014961

and using the 7.0 driver for Windows 8 here:
http://displaylink.com/support/downloads.php

So nothing is beta.

This particular system shows the DisplayLink service starting, and Device Manager shows Device ID 17E9 properly according to these articles:
http://www.displaylink.org/forum/showthread.php?t=896
http://www.displaylink.com/support/ticket.php?id=323

But I get Device Manager issue with no USB Display device.
Instead, I get it showing:

Other devices, ThinkPad USB 3.0 Dock

with these properties:

The drivers for this device are not installed. (Code 28)
There is no driver selected for the device information set or element.

I have been fighting this issue for a while, and realize I may need to wait for Lenovo to release their own Windows 8 drivers for smoother sailing, but it is strange that the same dock works fine with the same Windows 8 Pro (64 bit) on a ThinkPad T61. In other words, there's some sort of recovery/cleanup that seems to be needed, and hoping I can figure out what that procedure is, short of re-installing Windows 8 entirely. I also discussed this matter over here, in the now-closed forum:
http://www.displaylink.org/forum/showthread.php?t=1971

Uninstalling the DisplayLink 7.0 software and rebooting and reinstalling didn't help. Uninstalling the devices through Device Manager didn't help either. Sticking with Discreet video mode in the BIOS didn't help either (since single GPU is recommended since multiple GPUs like Optimus mode can be a problem with DisplayLink).

Any ideas? Will post diags below shortly...

See DisplayLink Support Tool 1.0.0.13 output attached.

Our drivers should work with this. It would be worth cleaning the install and trying again, following this article:

Hopefully that will let Windows associate our USB driver with our device.

Just to re-cap, here's my config:
left monitor 1920x1200, using DVD-D to DVD-D cable from laptop dock
center monitor 2560x1440 using DisplayPort to DisplayPort cable from laptop
right monitor using Lenovo USB 3.0 dock DVD-D to HDMI 1920x1080

Here's what did work for me:

Used the new DisplayLink USB Graphics Software for Windows* V7.0 M2
http://displaylink.com/support/sla.php?fileid=78

And tada, it updated the firmware in the Lenovo dock, and suddenly my 3rd display began working again.

Yep, the fix was that easy for me.

I also noticed that it only works when my ThinkPad W520 is set to Discreet Graphics mode in the BIOS.

So I made sure I'm using all the latest Windows 8 drivers, which are now GA, here:
http://support.lenovo.com/en_US/rese...DocID=HT063273
which means NVIDIA video driver 9.18.13.0614 / 9.17.10.2843, but it didn't matter, only Discreet Graphics seems to work with my config, Optimus mode is a no go (only my left and center monitors seen).

Annoying this in the Discreet Graphics mode, when my laptop is using its internal screen only, it locks up solid soon after finishing booting Windows 8. This was a problem throughout the betas, and now with the GA Win 8 64 bit and the GA level NVIDIA drivers as well, sigh. But that's a laptop issue, not a DisplayLink issue.

Anyhow, this is progress, turns out I didn't have to use the DisplayLink Install Cleaner.

Thank you!

Sigh, soon realized that resuming from suspend usually resulted in BSOD. So did unplugging monitors, then plugging them back in (power strip used when stepping away).

Much more stable leaving the NVIDIA driver alone (described above), changing over to thew new DisplayLink software (uninstall, reboot, then install). It's from the Lenovo site, with Lenovo USB 3.0 dock firmware, and driver to go with it from here, version V10611
http://support.lenovo.com/en_US/guid...DocID=UM014961

But unfortunately, still, about 1 in 5 wake-ups from sleep result in BSOD on Windows 8 64 bit. Re-cap, Windows 7 x64 was stable, with the same BIOS settings, same exact hardware config.

I've uploaded the log files for analysis, and please let me know if you need any other information.

Thanks!

Figured I'd post this new info, just in case it gives you any ideas for things I can do to help fix this.

In a few days, I'll backup, then try the DisplayLink cleanup utility, and NVIDIA cleanup. Then reinstall NVIDIA, then Lenovo branded DisplayLink software, and see how it goes.

Turns out that I can only turn off my primary 2560x1444 DisplayPort connected display (straight from the laptop's DisplayPort) by it's power switch, not by turning off the power strip it's plugged in to. Why? Well, I get BSODs if I use the power strip, very strange, seems to have to do with NVIDIA drivers (problem happened on one beta driver earlier this summer too). Still in NVIDIA Discreet Video mode in my W520's BIOS (NVIDIA Optimus mode still problematic under Windows 8).

But those issues have nothing to do with the DisplayLink stuff really, and at least I've found stability as long as I don't use the power strip for now.

Still waiting for a Windows 8 DisplayLink driver set with iPad-as-monitor support, looking forward to that experience.

Also found that the Lenovo provided driver here:
http://support.lenovo.com/en_US/guid...DocID=UM014961
works well finally with the Lenovo USB 3.0 dock under Windows 8, but I believe it still doesn't support iPad as an additional monitor.

Nevermind, the wait would be forever.
Looks like they've suspended all iPad support:

Everything working nicely now:
http://tinkertry.com/enjoy-windows-8...ernal-monitors
using Lenovo's variant of the DisplayLink Windows 8 drivers (latest DisplayLink drivers work too)

Woo hoo, victory at last! Strange that putting the NVIDIA 1000M into Discreet Mode, coupled with turning off VT-d in the BIOS, was most of the secret sauce.

Guess I'll just have to let go of the iPad 4th screen option I had shown at the bottom of this article:
http://tinkertry.com/mydesk

So glad such DisplayLink products exist at all, finally, 2560x1440 bliss, with 3 external monitors, on a laptop. Awesome!
