Testing the input latency of the Steam Link in different scenarios. Some considerations: CAT6 is 50ft; wireless is 5Hz through one wall (closed closet) and 30 ft directly from Modem to Link. Response times listed are specs of the monitor and TV, not results measured. Also, sorry for the orientation of the camera but it made the process easier.

No perceptible difference in any of the tests. Played Dark Souls PVP and had no image quality loss or FPS drops, either.
