Accessories The Surface Pro 4 is the fourth-generation Surface-series 2-in-1 detachable, designed, developed, and marketed by Microsoft.

The Surface Pro 4 is an update over its predecessor, featuring Skylake CPUs, more RAM and SSD options, and a 12.3-inch display with a greater resolution.

It includes heat pipes with a flowing liquid, which is meant to avoid the use of the internal fan when the device is used for less demanding tasks such as web browsing.

The common traits, inherited from the previous-generation Surface Pro 3, are a continuous kickstand, magnesium casing with a silver-colored back side, 802.11a/b/g/n/ac Wi-Fi radio, Bluetooth 4.0 Low Energy, full-size USB 3.0 port, microSD card reader, headset jack, Mini DisplayPort, Cover Port, and a renamed SurfaceConnect, a port on the side to connect a wall charger, Docking Station or Surface Dock accessories.

Windows 10 comes pre-installed with Mail, Calendar, People, Xbox (app), Photos, Movies and TV, Groove, and Microsoft Edge.

[5] The Surface Pro 4's CPU falls short of Microsoft's minimum requirements, and thus cannot be officially upgraded to Windows 11.

Although the Surface Pro 4 is backward compatible with the predecessor's Type Cover accessory, an attachable keyboard which doubles as a screen protector, the Surface Pro 4 Type Cover has been announced with and without a fingerprint ID sensor.

[8] The Surface Pro 4 is known to have wide spread flicker issues with the display[9] named as Flickergate[10] after the independent website flickergate.com which was set up by the affected users after getting no fix from Microsoft.

[11] Microsoft's spokesperson acknowledged the issue stating: "We are aware that some customers have experienced a screen flicker on Surface Pro 4 and are monitoring the situation closely.
