A few months ago, a crowdsource Kickstarter campaign started that would enable you to have three display on a laptop. It looks like Apple had similar idea as it has just unveiled a gaming laptop that comes with three built-in monitors and is called Project Valerie.
It has an automatic deployment mechanism and is the “world’s first concept design for portable multi-monitor immersive gaming.” The laptop packs three 17.3-inch 4K IGZO display with G-Sync and 180 NVIDIA Surround View gaming support. There is also features Razer’s Ultra-Low-Profile Mechanical switches, and Razer Chroma, for the monitors, keyboard, and trackpad.
Since this is just a concept piece, it will take some time before an actual device hits the market, but don’t expect it to be cheap.
