DIY Privacy Monitor – Lets Only You See What’s On Your Monitor

Tired of people trying to have a peak at what you’re looking at on your computer monitor?  I currently don’t have that problem but did have it when I used to work in an office and every time someone visited me in my cubicle, while talking to me, they’d always try to read MY emails or whatever was on the screen.  A user at has come up with a very nice solution for this problem, although I wouldn’t recommend doing this to your work computer.

Instructables user dimovi took a regular monitor and turned it into a “Privacy Monitor” that displays a white screen to everyone except those wearing special glasses.  So what do you need to turn your monitor into the one pictured above?  Check out the instructions below:

Do-It yourself privacy monitorTake an old LCD monitor (if you want to use a new one, be my guest); open it up from the back.  On the front of the monitor you’ll see two thin films on the glass, a frosted anti-glare film and a polarized film that filters out light you’re not supposed to see.  Cut out the polarized film with a box cutter or any other cutting tool and peel it off, there will be glue left on the glass part which can be removed with a damp cloth.  Now put everything back together the way you found it.

  1. Hello,

    My film “spoiled”. After I remove it from the monitor she aged and lost the polarized effect. where can I find another? It is normal to lose its effect after a while?
