there are 2 others that are identical also….

The monitors are not the same. It was totally cut and pasted. Look near the guys head, the top of the monitor and at the bottom right hand corner of the monitor.

If you're talking about the first and fourth images in the first row, look at the one one the right, specifically the right side of the image. *It extends off the side of the monitor.*

Also, in the highlighted images, you can see a white bar at the top of the bottom one that doesn't extend across the whole monitor, and isn't there in the other pic.

Maybe they are hiding the Excel documents as the status bar shows Excel is open.

The reason they faked it was because it wouldn't look very good if people saw that they were playing XBOX at this time.
