Before registering a new signal, check the items for horizontal and vertical timing under the specifications. • If new timing is registered, the old timing settings will be deleted. • If the difference between any of the factory preset timings and the user's timing is smaller than the allowable deviation, and the polarity of their synchronizing signals are the same, then they are considered to be the same, and the user's timing will not be registered. 24 Operation ViewSonic PT770
