in response to determining that a match does not exist between the input and the discovery key code, comparing, by the discovery service, the input with one or more additional discovery key codes assigned to one or more additional display devices of the plurality of display devices selected from at least one of:
a device connected to a WiFi network to which the input device is connected;
a device connected to a subnet to which the input device belongs; and
one or more display devices to which the input device has previously connected.
9. The method of claim 8 , further comprising:
receiving, by the discovery service from a display device, an answer to connect to the input device.
10. The method of claim 7 , further comprising:
determining, by the discovery service, that the input matches with a second discovery key code of a second display device of the plurality of display devices on a different WiFi network than the input device is connected to; and
transmitting an instruction, by the discovery service to the input device, to connect to the different WiFi network.
11. The method of claim 1 , wherein the display device is assigned to the discovery group based on a matching hint that indicates at least one of:
an IP address of the display device;
a WiFi network to which the display device is connected;
a wired network to which the display device is connected;
a geographic location of the display device; and
a previously-used identifier of the display device.
12. A system comprising:
a server comprising:
a network interface configured to couple to at least one network;
at least one processor coupled to the network interface; and
a computer-readable medium coupled to the processor and storing instructions to manipulate the at least one processor to execute a discovery service, the discovery service configured to:
register a display device of a plurality of display devices based on a unique identifier of the display device;
assign the display device to a discovery group, the discovery group associating the display device with other display devices of the plurality of display devices that are permitted by the discovery service to connect to an input device;
generate a discovery key code unique to the display device within the discovery group and a discovery key code length indicating a quantity of inputs of the input device to be included in a request for connection to a display device;
assign the discovery key code to the display device; and
transmit, via the network interface, the discovery key code to the display device for display on the display device.
13. The system of claim 12 , wherein the discovery service further is configured to:
receive, via the network interface, an input of the discovery key code from the input device; and
facilitate connection of the input device to the display device responsive to the input of the discovery key code.
14. The system of claim 12 , wherein the input device is a game controller and the display device comprises a television or monitor.
15. The system of claim 12 , wherein the discovery service further is configured to:
search for one or more display devices of the plurality of display devices that are available to connect to the input device;
determine a quantity of available display devices based on the search; and
determine the discovery key code length based on the quantity of available display devices.
16. The system of claim 12 , wherein quantity of inputs of the input device indicated by the discovery key code is dynamically adjusted based on a number quantity of currently registered display devices within the discovery group.
17. The system of claim 12 , wherein the discovery service further is configured to:
receive, via the network interface, a request including an input for connection to the display device from an input device; and
compare, by the discovery service, the input with the discovery key code.
18. The system of claim 17 , wherein the discovery service further is configured to:
