Review on PON-B15 Portable Computer Protector - 15.6" Waterproof, Frameless, Tilt Adjustment, Built-In Speakers, IPS with 60Hz Refresh Rate by Tracy Pfettscher

I have, well; try to use it as a second monitor when traveling. When it works it's a great product. However, I spend more than a week trying to identify cable connections than actually using it as a second monitor. Cable connections are weak, unreliable, and their operation does not cause difficulties. Mostly it works for 10-15 minutes and then starts flashing when connecting and disconnecting. When it works, your overall sound quality will also be worse than your standalone laptop or PC.
