Anti Glare Screen
Works very well for privacy and for eye protection. If you are standing beside it it is hard for someone to see your screen. I bought it for the purpose of my eyes. The screen protection was an added benefit.

SCREEN TOO SMALL
I ordered a 24" wide screen monitor and the screen is 2 inches too short top & sides. I was very disappointed!!!!

Works well
Besides being a privacy filter it also works as a screen protector and the matte works as an anti-glare. Easy to install and fits perfectly.

They really work!
These filters are well worth the money and fit my monitors perfectly. I tried a few cheaper versions and had to return because of sizing and lack of 'privacy'. These fit my screens perfectly and have maximum privacy.

Works great! Perfect Fit
It fits perfectly and works great. You can't even tell it's there. From the periphery my screen looks totally black. Very satisfied.

Exactly as described
Items were delivered quickly and by Staples own delivery team. The privacy screens do have both a shiny side and matte side to them they also come with both the tabs to slide the screen into if your computer has a set back screen and clear double sided adhesive strips which you don’t see unless directly looking at them or for them. Works great to keep screens private f...

solid privacy screen
does the job from close parameters. same angles but from slightly further distance such as just outside my office door loses its privacy component. otherwise it is a perfect fit for my monitor as well

Privacy Screen
Love Love Love it. Blocks people from seeing my screen as well as well as reduces the light so I don't get migraines as often.

Overall good screen
The screen works great with the exception that the sticky strips provided do not keep the screens on very well. Had to resort to scotch tape on the sides. Otherwise works as it should.

Barely works
It's not completely private. If someone is standing behind you they can still see everything. The side view is a bit more private and blacked out. Not happy with the quality especially for that price. I don't get why this thing costs so much and does so little.

3Mâ„¢ Black Privacy Filter for 18.5" Widescreen Monitor
They work great. Would love it if they were just a few cm's bigger. The notch is noticeable and doesn't go beyond the screen into the black area. It's a little distracting only because I keep wanting to move it but if I do the entire opposite side shows.

Doesn't work unless you're at a sharp angle
I tried this both sides. If you're standing to one side or the other it does obscure the screen but if you're standing directly in front of the monitor even if you're 8 ft away you can still see the monitor very clearly. The idea was that someone should not be able to stand behind me and see my screen. This doesn't work for that at all. Plus it arrived damaged. I'...
