3M PF240W1B Privacy Filter for 24 inch widescreen LCD monitor. Black anti-glare privacy screen. Protect data from visual hacking.

Terrible product, clearly visible netting lines which are very widely spaced, does almost nothing to shield the screen from the side.Please see the pictures to see this product vs a competitor product.I immediately started the return process as this doesn’t meet requirements from my work.

Really, really, really disappointed with this product, which DOES NOT PERFORM AS ADVERTISED. Not only is the angle or extent of privacy no better than that for the "standard" all black version, despite the extra expense, the performance is also grossly inferior. Even for the laptop owner's own viewpoint, this screen significantly dulls the colour contrast, adds a very grainy tinge, and is negatively impacted by diagonal lines running across the whole screen which make continued usage painful on the eyes. The screen also starts to curve slightly after even a day's usage, further impacting user clarity and refraction of light through it. Finally, the screen is also highly reflective (glossy) even in UK office light, making large portions of the screen wholly illegible with light reflections. The screen is no better on either side, despite one side being "gold" and the other a (still glossy/grainy) "black". Had to remove it after only a couple of days and unfortunately cannot use it at all. Stick with the original all black screen instead!!! Cheaper, and though still not perfect (someone sitting immediately to your left or right can still read your screen unless significantly angled away from them) at least it doesn't dull the user's own experience (eg it's not nearly as reflective). Would be keen to swap it for the plain black one, but have obviously already opened the package. Feeling completely missold on a product just not up to usual 3M standards.

Works really effectively and is a great fit. Others have commented on how well it works. It has a Matt and a glossy side. In the past I have always used the matt side on these things, but on this one it really sharpens the image on the screen and the extra reflectivity increases the effectiveness of the privacy.My only grumble is the fixing mechanism. Sticky strips to be attached to the screen means that it introduces areas of distortion at the edge of the screen or wherever you put the double sided tape. I have not yet had anything get behind the filter and had to remove it, so I can't comment on the re-use abilities of the double sided tape. I do prefer the variants that have a restraining strip that attach to the plastic surround, not to the screen itself.

It does what it is supposed to but here are the issues I found. 1) coating cracked on the top right, amazon replaced it BUT I would expect 3M to have got this bit nailed to a tee. 2) You can see fine diagonal lines running across the filter. Quite reflective, a matt coating would have been nice.I do like the fact it is reversible (Black / Gold) and comes with permanent and non permanent mounting options.

When I'm working on the go or at my client and partner offices I need to know my laptop and it's content remains secure.This privacy screen works fantastically at doing just that. The angles are great! People literally have to invade your personal space and come up behind you to see your screen.It's super easy to install and remove as needed and works well as an anti-glare screen too.If you have a micro-manager who is always looking over your shoulder this is ideal! and if asked tell them it's just an anti-glare screen, they can't stop you from using it ;).Best thing I've ever bought for the office!Fast delivery and product came in great condition. Though it isn't cheap, it makes the product even better because few people have them or even know they exist.

Diagonal lines make this unusable on my Dell Precision 1920x1080 portable workstation, so it's going straight back. Have a look at the photo. Actually even without this feature, it would be no use to me because it is just plain annoying and does not 'protect' the nearer parts of the screen, so if someone approaches from your left, yes they will see the left of the screen. It also has a nick cut out - I suppose to enable you to get a purchase on it when you want to remove it - which would be annoying also. Not recommended.

The adhesive strips are useless. Despite cleaning my screen thoroughly and ensuring it was dry, I applied the filter as per the instructions. Within just a few hours the filter was coming away from the screen and wasn't sticking. I could try an alternative sticking method although I am not sure how that would affect the transparency of the filter or the touchscreen capability. Massively disappointing. Would not buy again.

My main concern about using this was that screen/text clarity would be too impaired as I'm failry sensitive to distortion/sharpness but I've had this fitted to my laptop for 2x12-hour shifts and so far I'm very impressed with it. The level of clarity is fantastic and doesn't cause me any issues even with my extended windows of use. The privacy element kicks in such that colleagues sat to my left, right and diagonally behind me can't see any confidential information but instead are presented with a solid gold/orange screen. Fitting was simple, the slide mount tabs allow for smooth removal and replacement as necessary. My only gripe so far is it appears to be something of a fingerprint/dust magnet, probably to do with it being gloss compared to my matte laptop display but ultimately this is manageable as I'm focussed more on my work than fluff.
