Defective adapter replaced immediately, works flawlessly even over USB 2.0

I bought this I-TEC USB 3.0 Display Adapter Video DVI HDMI VGA (USB3HDTRIO), to connect two additional monitors to my laptop computer and be able to use all three displays simultaneously. I have a 6 year old Dell Inspiron 9400 laptop computer with built-in graphics card NVIDIA GeForce Go 7900 GS. Without an adapter, I was able to connect two additional monitors, but do not operate all three displays simultaneously.

After installing the driver software, the adapter turns out to be defective. A DVI connection on the monitor connected is detected, but no image appeared on it. A connected via the VGA adapter Monitor was not recognized. I had to return the adapter to Amazon.

Very positive was the settlement of the replacement. She became automatically and immediately ordered, without that I had to speak or correspond with someone.

After receiving the new adapter I connected him. All three monitors at once functioned as desired. I had only the "DisplayLink Manager" to set the required parameters, especially my desired arrangement of the three displays.

Although my laptop computer only has USB 2.0 ports, the adapter is functioning properly. The procedure, as an indication of a slow USB 2.0 connection is operated is, (the supplier of chipsets) summarized in a declaration at the site for DisplayLink. Not every whole image, but only the changes from one image to be transmitted via the USB connection.

I have not installed the driver software from the CD, but it downloaded from the Internet. The current version can be downloaded from the website of i-tec Europe or from the website for DisplayLink.
