Docking station - specs

I am looking at docking stations and the Toshiba dynadock® U Universal USB Docking Station
includes some specs I am unclear on.
Would really appreciate some clarification.
1.) Built-in HD Digital Video card supports up to 1920x1200 resolution.
All the screens I will be using are  HD 1080, would it be best to have a docking station with that output or will the Toshiba simply adjust accordingly and there will not be any difference to using one with automatic 1080 output.

2.) Built-in Digital Audio card adds virtual 7.1 surround sound though S/PDIF port.
Does this actually add anything to your existing sound or does it simly allow you to use a 7.1 surround system with the station.

1920 x 1200 resolution is designed for 16:10 monitor;   if you're using a 16:9 HD based panel, 1920 x 1080 is the exact equivalent, so it will work fine.      Note that this is a USB-based adapter, so the bandwidth won't be as good as an internal video card.

The "virtual sound" support simply means it adds an SPDIF port to play 7.1 audio through.    The drivers for this apparently add a "virtual" mode that expands audio with fewer channels to 7.1 -- just like many amps lets you use all 7 speakers for stereo material.    It does not actually turn stereo into 7.1 :-)   [Actually, I've yet to see one of those modes that sound any better -- or even as well -- as the correct playback for the specific material].
