Matte screen a screen much better brilliant!

We must not dream, right in direct sunlight, the filter is not removed any stray brightness.
But anyway! mitigat it so well that I rediscovered glare screen of my laptop. And there's no picture, a matte screen ca has much more class than a glossy screen! (Much less fingerprints, the screen looks cleaner longer).
I can then use my pc outdoors as the sun's rays do not strike the screen directly, formerly impossible without the filter.
Question arises: are ultra-patient and rigorous if you want a perfect installation of the filter, and do not hesitate to tape the filter on screen to help you unroll the adhesive face properly. If you trap dust in a drop-down, do not try to remove it! too bad, you had better prepare you.
