I've tried a number of powered usb hubs and none of them have been able to get more than 2 screens working simultaneously on Windows 7.

The most success I've had is with an Inland 7-port hub which gets 2 working consistently and 3 sporadically. The Syba 7-port USB 3.0 hub can't even get 1 working. For most of the hubs I've tried are rated for 480Mbps (minus the USB 3.0 which is 5Gbps), the AC power supplies are 5V at 2A.

What typically happens is you plug in one or two screens and they extend automatically, but as soon as you plug in another screen to the USB hub, the screen just gives you a gray screen.

Are there any hubs that reliably support 3 or more 9" LCD Screens? I've troubleshot the screens, USB ports on the PC, and USB ports on the hubs, and the hubs themselves. I've gotten up to the maximum of 6 screens running simultaneously using a combination of hubs and standard USB ports.

I've been using Doublesight DS-90U screens. I'm on a Windows 7 Enterprise Atom dual core 1.8Ghz system with a Foxconn motherboard with Intel graphics. I've tried two different versions of the Displaylink driver (including the latest).

I was thinking I might need a 3A hub--does what I describe sound like a power issue?

Can anyone recommend any hubs that they've gotten 3 or more screens working?

Thanks!
