I was pleasantly surprised that I could get the Insignia's built-in screen + DVI + VGA + USB3.0 adapter to work simultaneously with HD YouTube playback without lag on all 4 screens at 89% CPU load! This is a big problem for devices older than 5 years compared to my Thinkpad T550 which has a software limit of max 3 screens when using a document. The dock looks brand new/unused and comes without a power adapter, but that's not a problem as you can reuse your laptop.
