3MPrivacy Filter for 31.5" Widescreen Monitor (PF315W9B)

My work space is like a fish bowl. I often work with student or applicant confidential information on my computer. I always felt guilty whenever someone approached me and I hit Alt-Tab to switch to a benign screen - I worried that it suggested inappropriate use of my computer rather than work :-) !I'm using the 3M Privacy Filer PF 19 on a Dell LCD 19" monitor.Things to Consider When You Purchase a Privacy Screen:PRICE: I got out the catalog of the office supply chain that offers our institution a discount and checked the prices of privacy screens. Then I talked to our IT department and found out what they could offer my department. To say I had sticker shock is an understatement! One source was $100 more, our own IT department was $30 more than the screen I'm reviewing here and purchased from Amazon.STYLE: I checked different privacy screens throughout our 8 story building and decided that there was no clear advantage to having a frame around the screen. It added to the bulk and quite a bit to the cost. The screens I looked at without frames were held in place by small tabs that came with the screen and attached to the monitor frame. No one I spoke to who used the frameless models reported any problems with the screen falling out, and a number of users said it stayed in place without the tabs (as I discovered later, mine does too).EFFECTIVENESS: This privacy screen works very, very well. I've lost track of how many people have made me laugh by stopping and watching me stare at my screen as I'm intently reading something and asking me what's so fascinating about a monitor that's not on! I usually laugh, switch to a neutral web page and invite them over to "see" what I can see. The next question, after the "WOW", is where did I get it? I'm glad I kept the original packaging because I just pull it out and lend it to the person and usually I hear later that they've ordered one for their workstation(s).As another reviewer noted, unless someone is standing right behind you or within approximately 20 degrees of the center of your monitor, they won't be able to see what's on your screen. And yes, if someone walks behind you, there is a point in their pass-by that they can see your screen, but it's brief, and unless they stop to focus, they quickly are out of the "I can see your screen" zone.NICE FEATURES: There are two different "finishes", or looks to the screen. One side is a high gloss, the other matte. After using it both ways, I've decided that the gloss works better for my eyes. A second nice feature is a little half-circle, thumb-notch in the screen, at the top, that makes it easy and fast to pull the screen off the monitor if you want to share your screen with those around you. When I'm done sharing, I just pop it back into place. This is easy because as I mentioned before, the privacy screen stays in place wonderfully without the need for the tabs that are included.The 3M Privacy Filter -3M PF19 is a product that not only would I purchase again, but did - 4 more of them for just our little department. I've always trusted 3M products, and this item has reinforced that trust.

I mean, holy moly, over a hundred dollars for these things. Yeowch. But hey, they work perfect, the adhesive strips are nice and invisible, and the screen is mostly easy to see as long as you're right in front of it. Keep in mind, for those of you (like me) that have ultrawide screens that are NOT curved, these things work so well that, when sitting right in front of the monitor, the edges to either side of you tend to be far enough away that the picture dims considerably at those edges. The closer you sit to the monitor, the worse this gets. These things REALLY hide your screen. For that I am grateful. Highly recommended, but wow, can we please talk about the price? Ugh.

I used this on an HP Compaq LA2205wg screen and it fit PERFECTLY. There are 2 sides to this filter (which doesn't stick on the actual screen), one glossy and one matte. I used the matte side to face me, and from a distance the screen looks completely black. At closer proximity to the computer monitor, things are visible and if someone's standing directly behind, the screen is clearly visible. However, it has immensely increased the level of privacy and I can work happily knowing that no one's watching me from behind. The filter can be lifted for cleaning and the see through stickers that you attach to the screen are to help keep it put. Even without the stickers, the filter will stay put.Buy it, it's totally worth it, although HIGHLY priced.

Update: Had this for about a week now and I love it. It seems to have a tinted window effect that lowers the brightness of the screen and has reduced eye fatigue a lot. Must be a combination of anti-glare (using the matte side) and the darker tint since reducing the brightness/contrast of the monitor did not help.I bought this filter for its glare reducing properties. It has two sides: gloss or matte. The gloss side looks like a mirror and reflects all light. The matte is better defeating glare, but still reflects some light. Actually the LCD monitor I have is better are defeating glare, but not enough. After putting the filter on it has like a car tint effect that reduces a lot of the glare. The dimensions are perfect. Make sure you measure as perfect as possible, and before opening the package use the provided rulers printed on the package to verify your size. The installation is simple with the provided clear adhesive strips. The strips can barely be seen when installed.TIPS:1) The closer you are to the monitor the more you will start seeing the privacy filter properties at the edges of the screen. I have a 22" wide screen and at 25" away I can start to see darkening of the edges of the screen.2) Shake lint off the included cloth before use.3) For glare, make sure you choose the matte finish out.

Ordered this for my monitor at work since I work with confidential employee information on a daily basis. It works exactly like it's supposed to, prevents passersby from viewing my screen and also helps with glare, which gives my eyes a break. This version seems to fit my screen better than some other versions I've used In the past and I like the way it sticks directly to the screen with double-sided goo, rather than the old tabs I had to stick on the sides of my monitor with other versions. The price here on Amazon can't be beat by any other office supply retailer. I would reccomend this product and wouldn't hesitate to purchase again for another monitor.

they are great and do as they describe , Unless you are standing or siting in front of monitor you cant see what is going on . so if you need privacy in the work place , this is what you need , stops people having a look at your work when they shouldn't

While it performs its function properly, I'm not impressed with the form. The stickers are ugly - just bits of cut tape. For some reason, the filter was about half-an-inch too big, despite having ordered to measure - had to cut a bit off the bottom, so now the whole thing (with the ugly stickers) looks like a school project gone wrong.Also, the dimming works a bit -too- well- for the screen this size - looking at the middle of the screen, the sides are noticeably darkened. I suppose this can't be helped.

Always tricky to get these attached.

Perfect for use in a busy office!

Angle of visibility insufficient given wide screen. If you look at the centre then the sides are blacked out. Constantly having to move head left and right to see what is on the side of the screen rather than being able to see the screen from one head position. Design angle simply does not work on wide screens.
