Matching the field of view between Desktop and Oculus Rift DK2

[Jeff]

If the FOV set in Vizard does not match the physical FOV of the display then it will appear distorted. Since the user is much further away from the monitor than the HMD, the FOV of the monitor window is less relative to the user's total FOV. You may need to have a large monitor or multiple monitors to reproduce the same FOV of the Oculus. You can calculate the vertical FOV of the display using the following:

verticle FOV = 2*arctan((H/2)/D)
H = height of display and
D = distance of viewer from screen
