Review on 31.5 Inch Computer Privacy Screen Filter - 16:9 Aspect Ratio, Anti-Glare & Anti-Scratch Protection For Data Confidentiality by Adam Rogers

Look at pics and video! Shows what you get from multiple angles and both matte and shiny vs absent.This works very well (shiny side) for privacy. The matte side reduces glare but isn’t as good for privacy. I have included pictures showing the differences on my two screens in the same space. My office is very well lit, like high noon in an all white space in Arizona bright. I cannot say how this would be in a dimmer space. See videos and pics.If you have people directly behind you, it doesn’t block their view.
