With no tape required for installation, you can easily remove it at any time without worrying about leaving adhesive marks on your computer display. In addition, it is endurable and reusable due to the use of PET material. 2、PRODUCT SIZE: Computer private screen protector fits 26 inch, 27 inch widescreen displays with 16:9 aspect ratio. Actual filter size: width: 24.1inch (612.6 mm), height: 14inch (356 mm), diagonal: 27inch (685.8 mm). Please verify the width and height size of your computer screen before ordering.
