As to your question about producing moire patterns when the sensor has higher resolution (resolvable line pairs) than the lens: I'm skeptical that that's possible, since an optically blurred image can't be sharpened by using more pixels. You'll just get a better final image/print of the blur itself.
The effect is called Moire. It is caused by the grid pattern of the photosites in your sensor and the grid of pixels in the screen interacting. It happens when the grids do not exactly line up. It can occur with any gird or parallel lines. It is explanined in more depth here. To reduce this effect try to reduce how much of line the screen is to the sensor.

The patterns from work best and print themselves without moire more easily than the test patterns from the — either or . The concentric-circle patten in particular should be very effective, as it has decreasing distance between each circle making it almost guaranteed to interfere with your camera's sensor-pixel grid.
