"The AVF extendable tilt and turn wall TV/monitor mount not only frees up valuable desk space, but it also allows you to place the monitor in your choice of landscape or portrait view, and at your desired viewing height and angle for added comfort and reduced strain. The 20° tilt and 180° rotation allows you to position your screen at a comfortable viewing height and angle to reduce strain and glare. Plus, extend out 18.3cm / 7.2"" from the wall for easy manoeuvring and push back to just 6cm / 2.36"" from the wall when not in use. Easy tool-free adjustment makes it simple to change your positioning. VESA compatible 75 x 75mm to 100 x 100mm."
