Targus 4Vu Privacy Filter Screen for 19-Inch Widescreen (16:10 Ratio) Monitor (ASF19WUSZ) 19 inch Widescreen (16:10 Ratio)

I bought this because, unlike most other privacy screens which explicitly state they don't work vertical/portrait mode, this screen claimed to work in both landscape and portrait. It's fine in landscape, but not very effective in portrait.

Lo considero buen producto, no es del todo lo que esperaba ya que a máximo brillo de la pantalla una persona que está a lado tuyo podría ver sin problemas lo que estás haciendo en tu computadora. Cayo perfecto para mi Dell Latitud de 14 pulgadas y los soportes donde se coloca la pantalla son fáciles de instalar. Hay otras marcas como 3M que su protectores aun teniendo toda la pantalla con el brillo alto, no deja que otros vean lo que haces. Para que no se vea nada, tienes que tener tu pantalla con brillo medio a bajo. emmm!! Si lo recomiendo para aquellos que quieren que sea difícil que otros vean lo que estás haciendo, pero para aquellos que son exigentes y buscan que nada se vea, este producto no será para ustedes.

I didn't use this for a laptop but I found another great use for it. You can turn it 90° and cut it to the size of your license plate and it will completely block the view of an overhead toll camera! Would buy it again but it has held up so long so I don't think I would need another!

The kit and everything it comes with is great, and it fits my laptop like a glove. But the screen could definitely be darker/offer more privacy from angles.

I have two 27" Thunderbolt Displays and just moved into a new office with floor to ceiling windows and a great view. Due to the office configuration, I am sitting with my back to the windows and the glossy displays were a nightmare due to the glare. I almost couldn't see the screen. I tried the cheaper film protectors but it was a disaster of air bubbles, so I invested in these. Just installed them and the glare is 100% eliminated. In fact, the privacy screen covers only the display portion, not the borders, so you can see the contrast of the glare of the borders vs. non-glare of the display dramatically. As another reviewer said, I don't care for the mounting brackets so I plan to use large black rubber bands to strap the screens to the display. I am using small pieces of tape for now and can finally get some work done! UPDATED: After a few weeks, I still love these. I actually tried the tabs and they were useless, especially on the Thunderbolt displays. The display borders are flush with the display itself, so there is no way to slide the privacy screen into the tab. And when I tried with the slightest pressure they just popped off. I threw them away and went with the large black rubber bands - 2 on the sides and 2 on the top/bottom. This does the trick perfectly, as another reviewer said. One other note - I was a little disappointed in a few larger air bubbles but noticed you could remove them easily by lifting the screen from the bottom and slowly setting back down. Be sure to clean the screens on both sides with a damp soft cloth to remove smudges and dust. Once they are clean and affixed they work great. Finally, be aware that there is a glossy side and a matte side, either of which will work for privacy. But if you want to eliminate glare you'll need to use the matte side.
