When the monitor arm is fixed at the top end of the bar, the support plate for a small monitor comes approx. 44cm above table height. The plate can be tilted downwards. This Samsung monitor Samsung C49HG90 (49", 3840x1080) is 52cm high, so it won't work to fix a small monitor behind it without it being covered.
By the way, I would better not steal it, but buy it ;-)
