Review on HP EliteDisplay 21.5" Adjustable Backlit Monitor with Anti-Glare Screen, ASISP70, LED, HDMI, IPS - Ultimate Visual Clarity by Mario Romero

I would not recommend this product to anyone who wants their table flush with the wall. The arm mount seems to be designed for different sized monitors, so the arms are slightly wider for 21.5 inch monitors. To accommodate this fact, you'll need to bend your arms a bit so they stick out quite a bit behind the monitors. Arm ties don't have the flexibility to slide around easily like many other arm ties. Overall great monitors and perfect size but I would not recommend if you buy this product as the arm mount comes in handy specifically for these monitors.
