Windows 8, Lenvo USB 3.0 dock = lag + fuzzy image

Hate to say it, but perhaps the thing to try is a non-Lenovo dock. Given that all these docks use the same DL chipset (and their associated drivers), you would think that they'd behave remarkably similarly.

While my initial experience with the Plugable UD-3000 was a little rocky at first, it's been operating very well recently. I frequently swap between my MacBook Air and the Lenovo Twist, and things generally don't miss a beat (the exception being the missing USB 3.0 sound on the Mac side, coupled with some wired ethernet quirks on the Mac). GigE, Logitech Wireless mouse, a power hungry IBM Model M mechanical keyboard (with PS/2 to USB adapter), 1920x1080 DVI display... All just fine.

While I jokingly referred to Lenovo botching things in an earlier post, perhaps it's not a joke after all -- given that Lenovo has nearly smashed their solid IBM heritage to bits, it wouldn't be entirely surprising.

Perhaps Wim, or the other DL guys here, can possibly suggest whether something Lenovo has done (fatally in the hardware, or perhaps in some custom firmware for their dock) could contribute to the misery that's posted here.
