Can you use multiple Philips 221SU3 screens on a single computer
 

All,

After reading up on the Dsplaylink technology and seeing that up to 6 adaptors are supported I ordered 3 Phillips 21" Displaylink monitors.
If I hook up more than one all screens keep flashing.

I also have a separate adapter and a Toshiba portable displaylink screen.
When i add those together with 1 Phillips screen all goes well.

I've already updated both the displaylink drivers and the nvidia drivers to the latest versions, I'm running windows 7 64bit.

Trying it on two different laptops gives identical issues

Could it be that the Phillips screens are conflicting with each other ?

Tnx in advance,

Peter

Are the Phillips screens bus powered? It sounds like they cannot get enough power from the USB bus and cannot all switch on at the same time. They need to be connected to externally powered USB hubs (and the hub to have a power supply that allows it to deliver the maximum 5W on each port).

Got second one working
 

Wim,

Ik had them hooked up to a powered hub but this wasn't giving sufficient power i guess, i have now added a usb charger and hooked up the second usb to that, this allows me to hookup and work with a second one.

Phillips has a dedicated power adaptor for the screens in their manual but they don't actually sell them, guess I'll be looking for a alternative one.

Or do you know of USB powered hubs that provide that kind of power ?


Tnx & Rgds,

Peter

Plugable might be able to help with this, or at least know how much power can be delivered from their hubs.
