A:Answer Lenovo claims that you can use it as a standalone monitor. Here is the deal - your PC should have DP output. You will need DP to DP cable, and for the sound you will need a USB cable. And then, I personally didn't get to work the system together. Too much effort and too many cables. I am not discounting the product though - in fact I loved the concept. If you are on the market for All-in-One system - this is worth consideration. It's kind of modular All-in-One. You can get smaller monitor and more powerful computer. In time, you can replace monitor to a larger screen without spending the money on the computer. Or, you can replace computer without replacing the monitor. From visual perspective you get a standing monitor with the PC neatly packed behind it.
Please visit Lenovo's web site to see the detail. It's kind of hard to find information about this system, so you are welcome.
