Microsoft Surface Hub
The Surface Hub includes built-in cameras, speakers, microphones, Wi-Fi, Bluetooth, and Near Field Communication (NFC). It uses OneNote to enable people to collaborate on a digital whiteboard, supporting both finger and pen input. Surface Hub also includes other Office apps as well as Skype for Business, and can run other modern apps in a large-screen format. You can even connect apps from your personal device and drive them from Surface Hub.
Both Surface Hub models are powered by the 4th generation Intel Core Haswell processors (Core i5 for the 55-inch and Core i7 for the 84-inch) and runs the 64-bit version of Windows 10 Pro. The main differences between the two variants are screen size, resolution and its graphics adapter. The 55-inch model supports 1920x1080 Full HD and contains a Intel HD 4600 controller integrated in the CPU, while the more expensive 84-inch model has 3840x2160 4K resolution powered by a Nvidia Quadro K2200 discrete graphics adapter. Microsoft Surface Hub has dual cameras built into the device. When used for videoconferencing, the cameras can automatically change when the presenter moves from one side of the whiteboard to the other.
The screen of both models has a high-quality display, though it is not meant to be used for movie or TV screening. The screen is able to get very bright (reaching 424.38 cd/m2 at its brightest), but its black levels, are quite low (1.58 cd/m2). As a communications device, the screen can be viewed clearly at any angle. The screen has a matte finish which allows it to be less susceptible to glare. Additionally, the screen has a “100-point multi-touch projective capacitance optically bonded sensor” and a 120 Hz refresh rate, which allows it to detect what input is being used on the screen, whether it be a stylus or fingers.
