    HIGHLY Recommend THIS item
    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.

    We needed some protection from casual side views on a screen near a customer accessible area. We were very pleased to find an exact fit 3M privacy screen for the monitor model we were using. Easy to apply in minutes and it performs very well. We will buy 3M products of this type again over any other.

    5.0 out of 5 stars Works great to cut glare and high brightness
    Reviewed in the United States on August 19, 2014
    Size: 22.0" Widescreen MonitorVerified Purchase
    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.

    4.0 out of 5 stars Pretty good, but one caveat
    Reviewed in the United States on April 18, 2011
    Size: 22.0" Widescreen MonitorVerified Purchase
    I bought this for the office, since I wanted an anti-glare screen as well as some privacy. If you wanted the same thing, read on for my review:

    Application:
    This screen has a two step process for application.
    1. Affix this sticky tabs to inside your bezel on your monitor
    2. Insert your screen inside the bezel of your monitor, and then rely on those sticky tabs to keep the screen from falling off.

    Effects:
    Anti-Glare: The screen works pretty good! I already had a matte finish LCD, but the screen had a greater dulling effect against the glare of the sun. I highly recommend this filter if you are really going for the anti glare attributes.
    Privacy: Like advertised, the screen limits the viewing angle of the monitor so that the person directly in front of the monitor has the best view. Although it kind of defeats the purpose of these newer displays, promoting a greater viewing angle, this privacy screen works as advertised to fend off against nosy neighbors!

    Pros:
    Works as advertised!
    Anti Glare is surprisingly strong!
    Easy application (It's clean and sits inside the bezel so that you dont have to hang something on the front of the monitor, like the old school ones)

    Cons:
    Because you apply this sticky tabs to the monitor you want to dim, this thing isn't exactly portable and you can't easily transfer it from one monitor to another (as compared to the hanging old ones)
    Pretty expensive for what it is.

    Size: 22.0" Widescreen MonitorVerified Purchase
    Screen works okay as a privacy filter, and very good as a anti glare filter. Screen does work very well as a privacy filter when viewed at angles from side of monitor totally preventing prying eyes. But if a individual is looking over your shoulder, or even in-direct line of the monitor from across the room the information displayed on monitor is not filtered at all. The privacy filter has a glossy finish on one side and a matte finish on the other side, with each one providing a different degree of privacy and anti glare filtering capability. I made the mistake of applying the double sided tape supplied before I dry fitted the filter, and ended up damaging the filter trying to pull it off to refit.

    Our store has a relatively small counter where our customers pay their bill and we have long been plagued by those who lean over determined to see the computer screen and the information therein. After a little research and reading the reviews on Amazon, decided to try the 3M filter knowing it could be returned if unsatisfied; yeah, it's a little pricey.
    Arriving in 2 days with free Super Saver shipping, we could not be more delighted!!
    Simply put, it does exactly what it claims-if you aren't directly in front of the screen,you're not going to see anything but a black screen. Period. Finally, we have conquered the nosey!
    In the final analysis, it's true you get what you pay for. As for this writer (and the rest of the staff), the filter was worth every penny. If prying eyes are your problem, this is your solution.

    Privacy function works as advertised. Helps to reduce sunlight glare. Unfortunately, the reduction in clarity for reading negates the privacy and glare reduction. Had to return for a refund. Also, the screen fell off the monitor after one day. It had been installed with sticker tabs that would allow removal and insertion of the screen.
