A number of methods to display interlaced video on non-interlaced monitor are disclosed. One method is to display all of the incoming fields but one at a time, and correcting for the positional offset of one field relative to another in the interlaced data. An important aspect of the present invention is the correction of the positional offset of the two interlaced video fields. There are two ways presented to deal with the vertical offset of the two fields in accordance with the present invention. The first way is that the two fields can be displayed at different positions on the display using a non-interlaced display. The second way is that the video data can be altered to correct the positional offset between the fields. Another method of the present invention is to lock the frame rate of the output video to the incoming field rate or a multiple of the incoming field rate, or to certain sub-multiples of the incoming field rate. An important feature of this method is that each frame of the output monitor need not match the incoming field time precisely. As long as each output frame is displayed exactly the predetermined number of times, the appearance of smooth motion will be maintained.
