After thoroughly cleaning the screen, I used the tabs that came with the kit to allow the filter to be reinstalled. The tongues underneath fell off after 2 days. I have a 4K all-in-one Lenovo idea center and it toned down the resolution which made some things a bit blurry. Also, it didn't quite fit my 27" screen, it was about 2cm shorter at the top and bottom. Why not make it a little bigger so you can crop it? (I just measured the filter, it's 26 11/16). Let's get back to the blue-blocking lenses.
