3M PF140W9B Privacy Filter. 14 inch black Privacy Screen. Widescreen laptop filter. Anti glare. Protect your data from visual hacking.

Delivered right away, meets all the specifications and works exactly as described. The filter makes the screen look completely black from any angle except the frontal position. From the frontal position, visibility remains unchanged, with no significant decrease in image quality or resolution when the filter is on. Very easy to remove and re-apply. I haven't noticed any issues with the adhesive substance as reported by other users, it keeps working like the first time.

Second one of these privacy screens that I’ve had. Pricey, but excellent and easy to attach and remove to your laptop screen. I use the option provided to stick it on permanently. Unless someone is directly behind you they will really struggle to see your laptop screen The two sides provide a gold and dark option. I use the gold side as I think it looks much better and reflects the price (no pun intended). My colleagues have other options so I know that you can get much cheaper options that will work for you just as well, but we’ve all agreed this is the premier privacy screen of the ones we all have.

Great filter for keeping your online secrets away from prying eyes

Nicely packaged. It comes with three double sided tapes to stick the filter to the screen, and it also comes with a set filter holders to stick to the edge of the screen to slot the filter into place. The filter can be black or gold forwards, I found it made little difference except one looks a shade of gold and one a shade of black (you know what I mean!) from the side. It also comes with a cleaning cloth and instructions. The size is prefect for a 15.6 inch screen. That's all there is good about it. The efficacy is disappointing to say the least on both side (I went for the black in the end). There are five main issues with it which together make it a waste of money for me - I had to remove it in the end: 1. Moving from directly in front to round the side, it rapidly goes dark for the first 30 degree or so. But then it stops getting dark all the way round to the side. I do quite a bit of graphics work on the laptop and I can see the images I'm working on in a shade of dark grey all the way to an almost side-on view of the screen. Text is not legible but images are, so it is probably acceptable to keep text private only. 2. The problem with it rapidly half-working is that looking at the screen head-on, the edges are darker than the centre! This is a big distraction for me. I find myself moving my head from side to side to see the whole screen in the same shade. 3. It significantly reduced the brightness. I normally have my screen to about half brightness and now have to turn it right up to achieve the same brightness. (Which means I can do less work on the train because of the impact on battery life!). 4. The screen itself has a clearly visible mesh of parallel fine diagonal lines over it. If it was just darker, I could cope by turning up the brightness to the maximum as above, but looking through a diagonal mesh is very distracting. 5. The double-sided fixers are down the left, just where the icons are and they are very visible (they make the screen look "cheap"). OK, I could move the icons, but surely the filter should work for me, not the other way round? If you work only with text, have an amazing battery life (or work off the mains only), don't mind looking through a fine wire mesh, and don't mind the edges of the screen darker then the middle, then you may find this filter OK. But, for me, these things are too much of a distraction and unfortunately, this is over £40 very much not well spent. I shall look elsewhere.

The screen may be fine for most 17" laptops but is not really suitable for the MacBook Pro Unibody. Pros: 1) The filter does prevent people seeing data on your screen 2) the filter has a gloss and a matt side so you can use it to reduce the glare on your screen ( main reason I purchased it was to reduce the glare on my Macbook pro) 3) Is removable (the tabs do get a bit loose if you do this too often, and you will get finger prints all over it) 4) the quality of the plastic seems to be fairly good Cons: 1)The connectors that hold the filter in place look VERY cheap and tacky, on a sexy laptop in this, it looks like a do-it-yourself job. 2)If you have a high "dots per square inch" (DPI) resolution (like this17 inch screen) you will notice the separation of red green and blue, so it looks like a bit like you're looking through some kind of multicolour mesh. So not great during graphics or colour matching work. Does not produce the gauss effect so much for lower DPI screens, just tried it on my Samsung monitor. 3) There is a small piece cut out at the bottom of the filter so it looks a bit odd (its to help you remove the filter off the screen, still duff design) 4) I had to keep my screen on maximum brightness to match my previous monitor setting of 50%. 5) The battery life gets reduced by about 30% due to extra power consumption required to keep screen bright enough. Overall it does what it says on the tin but don't expect it to do it in style or efficiency. It doesn't fit the MacBook Pro well (wasn't expecting it either), I purchased it to reduce the glare on the screen without having to put the films on it and it does that well. In short, buy it but don't expect too much from it, if you want a privacy filter this is fine, as a basic anti glare this will also works for non high dpi screens. Its a little pricey for what seems like some sort of polarised plastic, but hey, most of us can't make them at home for less then what you pay for this.

It is a good fit and works well. But it wasn’t easy to get to that point. The guidance on the posting was helpful but it’s still quite hard to get to the exactly right size and I almost ordered the wrong one a couple of times before double checking. I couldn’t get the size I needed in gold which would have been better for my eyesight I think. You lose your touch screen with it. This is probably inevitable but I didn’t think to look to see if this was an option when choosing. So some guidance on that would be helpful, especially as it mentions that tablet/touchscreen is an option when exploring ways to stick it to the screen. The sticker system isn’t easy as it’s hard to get the bubbles out when sticking it to the screen.

These were a necessity for my organization's HR Specialist as her workspace is in an area with more traffic than would be desired. These provide ample privacy for her displays as almost any movement from center obscures the screen. Installation was straight forward; each filter included several strips of double-sided tape. This was applied near each edge of the inner side of the filter and the it was attached directly to the LCD surface. Adhesive tape was not my optimal choice for installation, but the tape is generally not noticed. I have not had any instance to remove theses filters, so I do not know if there is any difficulty in removing the adhesive.

もっと早く購入するべきでした。隣の席からは画面が全く見えずシャットダウンしているように真っ暗です。取り付け用シールの粘着力が弱いとコメントされているようですが、そのようなことは全くありません。３枚の取り付けシールが入ってますが、誤って取説の紙の上に１枚落としてしまい剥がすことができず無駄にしてしまいました。クリアーシートとブルーのシールの間に両面テープが入っているのですが、とても薄いので しっかり見ないと見つけられません。

Arrived quickly; easy to install; works perfectly!
