Review on 27 Inch Removable Privacy Screen Filter For Widescreen Monitors - PYS Shield For 16:9 Aspect Ratio, Anti-Glare & Blue Light Reduction, Compatible With 27" Sizes (New 2022 Version) by Scott Gendron

Although I measured as directed, this filter was just a little bit too big for my monitor. I was able to trim it down and you can't even tell it's there except for the privacy aspect. When you look at it from an angle, it looks like a turned off monitor. What I like the most is the blue light filtering. My eyes feel so much better after installing these filters on all of my monitors. I don't squint as much, and I have fewer headaches. If you spend all day on a computer, you should consider installing this filter for your eye's sake! The privacy filtering works great if someone is trying to view your monitor from any angle.
