Two screen displayed on monitors

This is an image of Bruce Nauman's piece titled 'Good Boy Bad Boy'.
This piece consisted of two videos with a different actor in each who read the same lines as each other which are very repetitive, slowly they become out of sync as they both talk at different paces and progressively get more of an angry tone as they go through the speech. When they become out of sync the audio and the images on screen clash with one another, creating a very confusing contrast, and almost makes you feel anxious when watching it. What interests me about this piece is that is isn't projected, it is displayed on two monitors which gives it a more separated feel, whereas two screen almost merges into each other and feels like one. The fact that they are on monitors works well with this work, this is because they are very different and they are clashing, its like putting two different channels on two TV's and putting them in the same room, they clash and become confusing.
