It comes with the Slim Fit Wall Mount*, which allows you to install it neatly and easily in any environment. QHC optimises space with its sleek design that blends seamlessly into your business.

Clean visuals in landscape or portrait mode

Even Bezel

The bezels are consistent and even on all four sides of the display, with the same thickness and dimensions. The new even bezel design prevents any visual issues from arising when the display is adjusted to portrait mode.

Centred VESA Holes*

The central positioning of the VESA holes* on the back of the display evenly distributes its weight for secure mounting. With the VESA holes* now shifted to the centre, users can adjust the display to portrait mode without the display tilting unintentionally.
