The company Expanscape created a prototype laptop called the Aurora 7 and has not one and two but seven screens attached. Each Aurora 7 screen shows its own windows and applications.
A laptop full of hinges, since the five screens extend around the main one. The main screen is 4K 17,3 inches and around it are three other screens of the same size and resolution. Above the left and right screens there is a seven-inch 1200p display. The seventh screen is touch screen, 1200p, seven inches and is located below the keyboard, next to the touchpad.
The original laptop weighs about 26 kg and is about 11 cm thick. The responsible GPU that runs seven 4K screens is an Nvidia GTX 1060. The laptop has an Intel Core i9-9900K processor and 64 GB of RAM. You can find more specifications here.
In future reviews, Expanscape wants to use the Nvidia RTX 2070, with options for the AMD Ryzen 9 3950x or Intel i9-10900K processor.
Even though it's mostly built to be one mobiles workstation and stay connected all the time, maybe some can run gamea. In addition to the main battery that only lasts an hour, it also uses a secondary 148Wh battery to power its additional displays, and that's over the FAA's legal limit for taking it with you on airplane.
Expanscape says that tries to fix it in future prototypes. As for the price, the company will ask you to sign a non-disclosure agreement, which forbids you to say publicly how much you bought it. This sounds like it probably won't be cheap.
