I use this adapter to display a second monitor from my T430s, which came with Windows 7 Pro, an Intel HD Graphics 4000 display adapter, and one VGA port.
I can use both external monitors at once: one for the main desktop and the other as an extension for palettes, etc. I sometimes use the T430s only with my small monitor and sometimes only with my main monitor. I'm able to easily switch the settings in the Display control panel to use either monitor without restarting. I'm able to configure each monitor individually in all these situations. I can also indicate in the control panel how the monitors sit in relation to each other.
I was able to use the clone mode, where each monitor displays the desktop at the same time. However, my monitors have different resolutions and aspect ratios, and I had to choose only one for both cloned displays.
I chose this device over a port replicator because I was confident it would work well. I didn't need all the features of a port replicator.
