To calculate how many pixels is one yard I used Breath of Heaven, whose range is 12 yards. It turned out that 12 yards is about 130 pixels, or 1 yard = 10.83 pixels. So you can easily calculate that the entire width of the screen (1368 pixels) is over 126 yards. In short, Monk sees on left or right sides no more than 63 yards.
Due to the fact that the camera is at unknown distance from the Monk, it was difficult (with available in Beta skills) to calculate the proper range behind and in front of Monk.
Other players tests result (using the Demon Hunter's Vault - thx HardRock and Theocide ) that the range behind the hero (bottom of the screen) does not exceed 35 yards. The range from hero to the top of the screen is larger.
