This is the basic anti-glare screen protector– not a blue filter, or a privacy filter. As you can see in the photos, when looking directly at the screen, the screen has the nice matte screen look. The flashlight was not turned off or moved in those 2 pictures of my new 17.3″ HP Envy laptop. It’s difficult to see in the photos, but the screen protector just fits over the viewable screen area and not the black borders or the webcam.You get 2 matte screen protectors in the package. Each matte screen protector comes sandwiched between two clear sheets labeled 1 and 2.When I started, my laptop was only days old, so I thought it wouldn’t have dust on it. I looked for dust on the screen and didn’t see any, so I went ahead and followed the directions of peeling back some of layer 1 and applying the matte protective sheet. I turned on the laptop so I could see where the protector should be applied. Well, it was obvious after applying it that the matte screen had some dust trapped under the protective layer. So here’s what I learned. Some dust you can not see without a bright light. The screen needs to be dustless. Turn off the laptop. Shine a very bright flashlight at the edge of the screen which will highlight the dust. Use clear packing tape to gently lift off the dust. (The included “Dust-absorber doesn’t work as well as the clear packing tape.) When the dust is entirely removed, turn on the laptop so that the screen shows the area to cover. I started on the upper left and peeled about 2” of the left side of layer 1 from under the matte screen protector while keeping the clear outer layer (layer 2) intact. Then I lined-up the left edge and used the “applicator card” to remove the air bubbles as I went from left to right. Great, next the clear sheet labelled number 2 needs to be removed. But, be careful, the matte protective sheet tends to lift off the laptop screen as you remove the number 2 clear sheet. For me, the matte protective sheet went right back into place onto the screen with the help of the applicator card.If you can’t move what looks like an air bubble– well likely there’s some dust trapped there. On my first try, I found that peeling the film back off to remove the dust just made things worse.Well, now with my matte screen protector installed, my laptop has become a favorite.
